White dwarfs are the result of the evolution of stars that are not massive enough to become neutron stars or black holes when they die and are what most stars become when they die. Option C) is correct.

A white dwarf is the final stage of evolution for low to intermediate-mass stars, including our Sun, after they have exhausted their nuclear fuel and shed their outer layers as a planetary nebula. The core of the star collapses to a very small, hot, and dense object that is supported against further collapse by electron degeneracy pressure. White dwarfs are not massive enough to become black holes or neutron stars, and they are not the same as brown dwarfs, which are failed stars that never ignited nuclear fusion in the first place.

The red dots have a negative charge are known as electron.

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical characteristic of electric charge. You might have a positive or negative electric charge. Unlike charges attract one another while like charges repel one another.

A positively charged nucleus and one or more negatively charged particles known as electrons make up an atom.

There is no overall charge in any atom (neutral). This is due to the fact that they have an equal amount of positive and negative electrons. The atom becomes neutral as a result of the cancellation of these opposing charges.

Answer:

\(\boxed {\boxed {\sf 243.75 \ J }}\)

Explanation:

Kinetic energy is energy an object has due to motion. The formula is:

\(KE=\frac {1}{2}mv^2\)

The mass of the object is 78 kilograms and the velocity is 2.5 meters per second.

\(m= 78 \ kg \\v= 2.5 \ m/s\)

Substitute the values into the formula.

\(KE= \frac {1}{2} (78 \ kg)*(2.5 \ m/s)^2\)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Solve the exponent first.

\(KE= \frac {1}{2}(78 \ kg)*6.25 \ m^2/s^2\)

Multiply all three numbers together.

\(KE=39 \ kg * 6.25 \ m^2/s^2\\\)

\(KE=243.75 \ kg*m^2/s^2\)

1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 243.75 kg *m²/s² is equal to 243.75 Joules.

\(KE=243.75 \ J\)

The object has 243.75 Joules of kinetic energy.

F/4F is the correct answer because the electrostatic force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.

This means that if the distance is doubled, the inverse of the square of the distance will increase four times, thus reducing the force by a factor of one-fourth. So, if the distance is doubled, the electrostatic force between the charges will become F/4F.

This can be expressed mathematically as F1/d2 = F2/d22, where F1 is the original force and d1 is the original distance and F2 is the new force and d2 is the new distance. Thus, if d2 is doubled, the new force will be F/4F.

a) The initial phase angle is 45 degrees, (b) displacement at t=0 s is 1.414 m, (c) the velocity at t=0 s is -5.656 m/s, (d) maximum velocity is 1.568 m/s.

Simple harmonic motion (SHM) is a type of periodic motion in which an object oscillates back and forth around a central point with a constant amplitude and a sinusoidal pattern.

The equation of a simple harmonic motion (SHM) is given by:

y = A cos(ωt + φ)

where A is the amplitude, ω is the angular frequency, t is the time, and φ is the phase angle.

Comparing with the given equation, we have:

A = 2.0

ω = 4

φ = 45 degrees

a) The initial phase angle is 45 degrees.

b) To find the displacement at t=0 s, we substitute t=0 in the given equation:

y = 2.0 cos(4t + 45)

y = 2.0 cos(45)

y = 1.414 m

Therefore, the displacement at t=0 s is 1.414 m.

c) To find the velocity at t=0 s, we differentiate the given equation with respect to time:

v = dy/dt = -2.0ω sin(ωt + φ)

Substituting t=0, we get:

v = -2.0 x 4 sin(45)

v = -8.0 x 0.707

v = -5.656 m/s (Note: the negative sign indicates that the direction of the velocity is opposite to the direction of the displacement)

Therefore, the velocity at t=0 s is -5.656 m/s.

d) To find the maximum velocity, we differentiate the given equation with respect to time and set it equal to zero (since the maximum velocity occurs when the displacement is zero):

v = -2.0ω sin(ωt + φ) = 0

Solving for t, we get:

ωt + φ = nπ (where n is an integer)

4t + 45 = nπ

t = (nπ - 45)/4

At t=0, n=1, so:

t = (1π - 45)/4 = -11.25 degrees

(Note: the negative sign indicates that the displacement is at its maximum position, whereas the velocity is zero)

Substituting this value of t in the expression for velocity, we get:

v = -2.0 x 4 sin(-11.25 + 45)

v = 8.0 x 0.196

v = 1.568 m/s

Therefore, the maximum velocity is 1.568 m/s.

The horizontal distance traveled by the cannonball at 30° and 60° angles will be the same, given that the initial velocity and mass of the cannonball are held constant.

According to projectile motion equations, the horizontal distance traveled by the cannonball can be calculated as:

d = (v²/g) * sin(2θ)

where d is the horizontal distance traveled by the cannonball, v is the initial velocity of the cannonball, g is the acceleration due to gravity, and θ is the angle of the cannon with respect to the horizontal.

For a given initial velocity, the maximum range is obtained when the angle is 45 degrees. At angles, greater or less than 45 degrees, the range is less.

When the cannon is fired at an angle of 30°, the theoretical horizontal distance can be calculated as:

d = v²/g) * sin(60°)

d = v²/g) * 0.866

When the cannon is fired at an angle of 60°, the theoretical horizontal distance can be calculated as:

d = (v²/g) * sin(120°)

d = (v²/g) * 0.866

Both of these equations have the same value for the sine of the angle, which is due to the fact that the sine function is symmetric around 90 degrees.

Therefore, the horizontal distance traveled by the cannonball at 30° and 60° angles will be the same, given that the initial velocity and mass of the cannonball are held constant.

An online calculator of Simpson's rule is a tool available on various websites that allows you to approximate the definite integral of a function using Simpson's rule.

Simpson's rule is a numerical integration technique that approximates the area under a curve by fitting a second-degree polynomial (i.e., a parabola) to three consecutive points on the curve, and then integrating the polynomial over the interval of interest.

The formula for Simpson's rule can be expressed as follows:

∫_a^b f(x) dx ≈ (b-a)/6 [f(a) + 4f((a+b)/2) + f(b)]

where f(x) is the function to be integrated, a and b are the limits of integration, and the approximation sign indicates that the formula is an approximation of the exact value of the integral.

Online calculators of Simpson's rule typically have fields for entering the function to be integrated, the limits of integration, and the number of subintervals (i.e., the number of parabolas to be used in the approximation). The calculator then applies Simpson's rule to the function over the specified interval, and returns an approximate value of the definite integral.

Some online calculators of Simpson's rule may also provide additional features, such as graphing the function and the approximation, or comparing the results of Simpson's rule to other numerical integration techniques.

The graph shows that the block of ice is initially heated until it reaches the melting point, where it undergoes the phase change from solid to liquid.

Based on the information provided, the graph of temperature against thermal energy absorbed indicates the heating process of a block of ice starting at -20°C until it turns to steam. The key feature to consider in this scenario is the plateau region on the graph, which represents the phase change from solid to liquid and from liquid to gas. The latent heat of fusion of ice is the amount of energy required to change a substance from a solid to a liquid state without changing its temperature. In this case, it is given as 340 kJ/kg. During the initial phase, as the ice is heated from -20°C, its temperature gradually rises until it reaches the melting point of ice (0°C). At this point, the energy absorbed is used to break the intermolecular bonds and convert the ice into water. The temperature remains constant at 0°C during this phase change, despite the continuous addition of thermal energy. Once all the ice has melted into water, the temperature starts rising again until it reaches the boiling point of water (100°C). During this phase, the thermal energy absorbed is utilized to convert the liquid water into steam or water vapor. Similar to the melting phase, the temperature remains constant at the boiling point during this phase change. The plateau regions on the graph represent the latent heat of fusion and the latent heat of vaporization, respectively. These phases require a significant amount of thermal energy to break intermolecular bonds and change the substance's state without a change in temperature. Then, the temperature continues rising until it reaches the boiling point, where another phase change occurs from liquid to gas. The latent heat of fusion of ice (340 kJ/kg) represents the energy required to convert the ice into water without changing its temperature.

The skydiver is falling at a velocity of 212 kilometres per hour. The speed of the skydiver is 212 miles per hour.

If a skydiver leaps out of a plane and lands at 212 mph, it is necessary to know the skydiver's velocity and speed. Velocity is speed with a direction, whereas speed just exists as a number with a speed unit at the end. While velocity refers to both the speed and direction of an object's motion, speed is the rate at which an object moves along a path over time. The skydiver is falling at a speed of 212 kilometres per hour. 212 kilometres per hour is the speed at which the skydiver is travelling. Speed is the rate at which an object travels along a path over time, as opposed to velocity, which describes the speed and direction of an object's motion. A scalar quantity is speed.

The height to which the ball rises is approximately 20.3 meters.

We can use the principle of conservation of energy to determine the height to which the ball rises. At the instant the ball leaves the foot, the total initial energy is the kinetic energy of the ball:

K_i = 1/2 * m * v_i^2

where m is the mass of the ball, and v_i is the initial velocity of the ball, which is 20 m/s. Substituting the given values, we get:

K_i = 1/2 * 0.45 kg * (20 m/s)^2 = 90.0 J

At the highest point of the ball's trajectory, its kinetic energy is zero, so all the initial energy has been converted into gravitational potential energy, given by:

U_f = m * g * h

where g is the acceleration due to gravity, which we take as 9.81 m/s^2, and h is the height to which the ball rises. Substituting the given values, we get:

U_f = 0.45 kg * 9.81 m/s^2 * h = 4.3965 h

Now we need to find the height h. To do this, we can use the principle of impulse and momentum, which states that the impulse of a force acting on an object is equal to the change in the object's momentum:

I = F * t = m * (v_f - v_i)

where I is the impulse of the force, F is the average resultant force acting on the ball, t is the time for which the force acts, and v_f is the final velocity of the ball, which is zero at the highest point of the ball's trajectory. Solving for v_f and substituting the given values, we get:

v_f = v_i - (F * t) / m

v_f = 20 m/s - (180 N * 0.050 s) / 0.45 kg

v_f = 2.2222 m/s

Now we can use the principle of conservation of energy to find the height h:

K_i = U_f

1/2 * m * v_i^2 = m * g * h

h = (1/2 * v_i^2) / g

h = (1/2 * (20 m/s)^2) / 9.81 m/s^2

h = 20.3 m

Therefore, the height to which the ball rises is approximately 20.3 meters.
