what is the potential difference between yi =−8cm and yf =8cm in the uniform electric field e⃗→ =(20,000i^−50,000j^)v/m?

Answer:

Matter in the universe is made up of atoms, particles if electrons were to be stationary, they would have fallen into the nucleus because of electrostatic force acting on them destroying very existence of an atom we know.

To find the electric field vector on the y-axis at y = 31 cm due to the two charges, we can use the principle of superposition. The electric field at a point is the vector sum of the electric fields produced by each charge individually.

Given:

Charge q1 = +12.6 nC at the origin (x = 0)

Charge q2 = -31.3 nC at x = 24 cm = 0.24 m

Point of interest: y = 31 cm = 0.31 m

We can use Coulomb's law to calculate the electric field produced by each charge at the point of interest.

Electric field due to q1 (E1):

Using Coulomb's law, the electric field at point P due to charge q1 is given by:

\(E1 = k * (q1 / r1^2) * u\), where k is the Coulomb's constant, r1 is the distance from q1 to P, and u is the unit vector pointing from q1 to P.

Since q1 is located at the origin, the distance r1 is the distance from the origin to P, which is equal to the y-coordinate of P.

r1 = y = 0.31 m

Plugging in the values:

E1 = \(k * (q1 / r1^2) * u1\)

Electric field due to q2 (E2):

Similarly, the electric field at point P due to charge q2 is given by:

E2 = k * (q2 / r2^2) * u, where r2 is the distance from q2 to P, and u is the unit vector pointing from q2 to P.

The distance r2 is the horizontal distance from q2 to P, which is given by:

r2 = x2 - xP

  = 0.24 m - 0

  = 0.24 m

Plugging in the values:

E2 =\(k * (q2 / r2^2) * u2\)

Total Electric Field (E):

The total electric field at point P is the vector sum of E1 and E2:

E = E1 + E2

Calculating the magnitudes and directions:

1. Calculate E1:

E1 = k * \((q1 / r1^2) * u1\)

2. Calculate E2:

E2 = k \(* (q2 / r2^2) * u2\)

3. Calculate E:

E = E1 + E2

Remember to include the appropriate signs and directions for the electric field vectors based on the signs and electric of the .

The age of the sample can be determined using the first order equation of the nuclear decay. The age of the parent isotope here is 45 years.

Unstable radioactive nuclei undergo nuclear decay to produce more stable nuclei with more life time. The time required to decay half of the initial amount of a material is called its half life.

The half life of a sample is related with the decay constant k as follows:

k = 0.693/t1/2

Given that, t1/2 = 15 years

k = 0.693/15 = 0.0462 yr⁻¹

The first order equation of the decay process is written as:

k = 1/t ln w0/wt

where w0 is the initial amount and wt be the amount after time t.

then t = 1/k ln w0/wt

Given that, the sample was decayed to one eighth of the initial amount .

t = 1/k ln 8

 = 1/0.0462 ln 8

 = 45 years.

C) 3 mls to the right. The positive direction is to the right, the velocity of the wave is in the positive direction, which means it is 12 mls to the right.

The equation y(x,t) = 6 cos(3x + 12t) describes an ID travelling wave on a string. The velocity of the wave can be determined by finding the coefficient of t in the argument of the cosine function. In this case, the coefficient of t is 12. Since the positive direction is to the right, the velocity of the wave is in the positive direction, which means it is 12 mls to the right. Therefore, the correct answer is C) 3 mls to the right.
The given equation for the traveling wave is y(x,t) = 6 cos(3x + 12t). To find the wave's velocity, we must identify the wave's angular frequency (ω) and wave number (k) from the equation. In this case, ω = 12 and k = 3. The wave's velocity (v) can be calculated using the formula v = ω/k.

The part of the microscope that the objectives are attached to is called the (C) nosepiece.

The nosepiece is a rotating mechanism located below the microscope's body tube. It holds the objectives, which are the lenses responsible for magnifying the specimen. The nosepiece typically has multiple positions, allowing the user to switch between different objective lenses for varying levels of magnification.

This convenient feature eliminates the need to manually remove and replace objectives when changing magnification. By rotating the nosepiece, different objectives can be brought into position above the specimen. This allows for quick and efficient adjustments in magnification without disrupting the viewing process.

Hence, the nosepiece plays a critical role in the microscope's functionality by providing a convenient way to switch between objectives and adjust the magnification level.

A football player throws a football 30 meters in 2.5 seconds, divide 30 by 2.5 and get 12.

An object's speed, also known as "v," is the amount by which its position changes over time or by how much it changes per unit of time, making it a scalar number.  

The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance traveled by the object divided by the duration of the period. Velocity and speed are not the same thing.

The parameters of speed are time divided by distance. The metre per second (m/s), the SI measure of speed, is the most widely used unit of speed in daily life.

The amount manager should invest today in GIC to have C$5 million in 10 years is C$2,775,633.

To find the amount the manager should invest today in a GIC, we can use the future value formula:

FV = PV(1 + r/n)^(nt)

Where FV is the future value, PV is the present value, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, FV = C$5 million, r = 6% (0.06), n = 12 (compounded monthly), and t = 10 years. We need to solve for PV.

Rearrange the formula to solve for PV:

PV = FV / (1 + r/n)^(nt)

Now, plug in the given values:

PV = 5,000,000 / (1 + 0.06/12)^(12*10)

PV ≈ C$2,775,633

Explanation:

The acceleration of the object is closest to 2.62 m/s² when the friction force on this object is 30n to the left and has an horizontal pull of 50n.

To find the acceleration of the object, we need to use Newton's second law, which states that the net force on an object is equal to the product of its mass and acceleration:

F_net = ma

where F_net is the net force acting on the object, m is the mass of the object, and a is its acceleration.

In this case, the net force on the object is the sum of the force applied by the pull and the force of friction:

F_net = F_pull - F_friction

where F_pull is the force applied by the pull, and F_friction is the force of friction.

Substituting the given values, we get:

F_net = 50.0 N - 30.0 N = 20.0 N

Since we know the weight of the object is 75.0 N, we can find its mass using the formula:

F_gravity = mg

where F_gravity is the force of gravity or weight, m is the mass, and g is the acceleration due to gravity, which is 9.81 m/s² on Earth.

Substituting the given weight, we get:

75.0 N = m * 9.81 m/s²

Solving for m, we get:

m = 7.64 kg

Now we can use Newton's second law to find the acceleration:

a = F_net / m = 20.0 N / 7.64 kg ≈ 2.62 m/s²

at the top           h = L - L cos 50     height to which pendulum raised

   h = L (1 - cos 50) = 1.2 * .357 = .429 m

potential energy = m g h

PE = .8 kg * 9.8 m/s^2 * .429 m = 3.4 J

If a  frictionless pendulum has a length of 1.2 m and a mass of 0.8 kg. If the pendulum is raised to an angle of 50 degrees before it is released, then the pendulum’s gravitational potential energy at the point of release would be 3.4 Joules, therefore the correct answer is option A.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.

As given in the problem if a frictionless pendulum has a length of 1.2 m and a mass of 0.8 kg. If the pendulum is raised to an angle of 50 degrees before it is released,

At the top height to which the pendulum was raised,

Height  = L (1 - cos 50) = 1.2 * 0.357 =0 .43 m

The potential energy = m× g ×h

The gravitational potential energy =0.8 * 9.8  * 0.429 m = 3.4 Joules

Thus, the pendulum’s gravitational potential energy at the point of release would be 3.4 Joules, therefore the correct answer is option A.

Explanation:

The correct answer is The minuscule hills and valleys of two contacting surfaces grow, which causes friction. Describe how friction is impacted by the pressure pressing two surfaces together. The amount of friction between two surfaces increases as the force pulling the surfaces together increases.

Frictional force is the force produced when two surfaces slide against and touch each other. The surface texture and amount of force needing them together have the biggest an impact on these forces.

The forces of adhesion between the sites of contact areas of the surfaces, which are always minutely uneven, are the primary cause of friction between objects. The action of the imperfections of the harder surface tilling across the softer surface shears these "fused" connections, causing friction.
