Answer:

Assumption: the acceleration of this vehicle is constant until it comes to a stop.

Acceleration: \((-2)\; \rm m\cdot s^{-2}\).

The acceleration of this vehicle is negative because the velocity of this vehicle is decreasing over time.

Explanation:

Assume that the acceleration of this vehicle, \(a\), is constant. The SUVAT equations would apply.

The time \(t\) required for braking is neither given nor required. Hence, make use of the SUVAT equation \(v^{2} - u^{2} = 2\, a\, x\) to relate \(u\), \(v\), \(a\), and \(x\!\).

Rearrange this equation to find an expression for \(a\), the acceleration of this vehicle:

\(\begin{aligned}a &= \frac{v^{2} - u^{2}}{2\, x} \\ &= \frac{(0\; \rm m\cdot s^{-1})^{2} - (10\; \rm m \cdot s^{-1})^{2}}{2\times (25\; \rm m)} \\ &= \frac{0^{2} - 10^{2}}{2 \times 25}\; \rm m \cdot s^{-2} \\ &= -2\; \rm m\cdot s^{-2}\end{aligned}\).

Acceleration is the rate at which velocity changes over time.

The velocity of the vehicle in this question is getting smaller over time. Hence, the rate of change of the velocity of this vehicle (that is, the acceleration of this vehicle) would be a negative number.

The minimum thickness of the film needed to cancel light of wavelength 550 nm reflected toward the eye at normal incidence is zero. No other wavelengths of visible light will be cancelled or enhanced in the reflected light.

To determine the minimum thickness of the film needed to cancel light of wavelength 550 nm reflected toward the eye at normal incidence, we can use the concept of interference in thin films.

For constructive interference to occur and cancel the reflected light, the phase difference between the light waves reflected from the top and bottom surfaces of the film should be an integer multiple of the wavelength.

The condition for constructive interference in a thin film is given by:

2nt = mλ

Where:

n = refractive index of the film

t = thickness of the film

m = integer representing the order of the interference (m = 0 for the first minimum)

λ = wavelength of the incident light

In this case, the incident light is traveling from the medium flint glass (refractive index 1.62) to the fluorite coating (refractive index 1.432).

For the first minimum (m = 0), the phase difference should be zero. Thus, the thickness of the film (t) should satisfy:

2nt = 0

Since the refractive index of the film is less than the refractive index of the medium flint glass, we can assume the film is thinner than a wavelength of light. Therefore, we can disregard the higher-order interference effects.

Now we can solve for the minimum thickness of the film (t) using the equation:

2nt = 0

t = 0 / (2n)

t = 0

The minimum thickness of the film needed to cancel light of wavelength 550 nm reflected toward the eye at normal incidence is zero.

(b) Since the minimum thickness of the film is zero, no other wavelengths of visible light will be cancelled or enhanced in the reflected light.

Therefore, option (b) is the correct answer. It is important to note that increasing the speed of the ball will also increase its kinetic energy and potential energy, as well as the tension in the string.

The force on the string holding the ball swinging in a circle is related to the speed and mass of the ball. When the ball is moved twice as fast, the force on the string will increase. This increase in force can be calculated using the equation F = mv²/r, where F is the force on the string, m is the mass of the ball, v is the velocity of the ball, and r is the radius of the circle. As the velocity of the ball is doubled, the force on the string will be four times as great. This is because velocity is squared in the equation.

The work done by the tension is 593.4 Joules, the work done by the gravity is -179 Joules, the work done by the normal force is 0 Joules and the increase in the thermal energy of the create and incline is 25.7 Joules.

The mass of the crate is 8 kg and it is being pulled up 5m on 30 degree inclined plane by a rope inclined at an angle 18 degree above the incline itself.

The tension in the Rope is 120 Newton and the coefficient of friction between the crate and the incline is 0.25.

The angle made by the tension T with respect to the horizontal ground will be 30 degree + 18 degrees.

So, the angle made by Tension is 48°.

There will also be a normal force N on the crate.

(a) Solving for work done,

So, work done by tension,

W = Tcos48°(5)

W = 593.4J

Work done by gravity, W',

W' = Mgsin30°(5)

W' = -179J

Work done by gravity will be negative because the direction of the force applied and the displacement of the crate is opposite.

There will be no work done by the normal force because the force applied by the normal force is perpendicular to the direction of the motion of the crate.

(b) the increase in the thermal energy of the create and inclined will be equal to the work done by the friction,

Work done by friction = un(5)

Work done by friction = (uMgcos30°-Tsin18°)(5)

Work done by friction = 25.76J.

acceleration due to gravity = g = 9.8 m/s²

Mass of the earth is= 6.4*10^24

G = 6.67*\(10^{-11}\)

In comparing the human eye to a camera, the film would be located in the eye's B) retina.

The retina is the innermost layer of tissue in the eye that contains photoreceptor cells known as rods and cones.

These photoreceptor cells convert light into electrical signals that are sent to the brain via the optic nerve, where they are interpreted as visual images.

In a camera, the film or image sensor serves the same function as the retina in the human eye. The film or sensor captures the light that enters the camera through the lens and converts it into a photograph.

The momentum of an isolated system before and after a collision must equal each other, according to the law of conservation of momentum.

The only thing that happens when two bodies collide is that their momentum changes. Thus, for bodies colliding, changes in momentum are always equal and opposite. The momentum of the other body must decrease by the same amount if the momentum of the first body increases. As a result, momentum always remains constant.

Regardless of the type of collision, momentum is always conserved. Although mass is conserved regardless of the type of collision, an inelastic collision may cause the mass to deform, leading to the two possibilities.

Explanation:

The momentum is equal to the mass times the velocity, so for each car the momentum is equal to

Car A

Momentum = Mass x Velocity

Momentum = 1,500 kg x 10 m/s

Momentum = 15,000 kg m/s

Car B

Momentum = Mass x Velocity

The Maria travels at an average speed of 3 miles per hour. the difference between the shift of position or displacement (x) and the time periods (t) during which the displacement takes place.

What is the purpose of average velocity?

An element's displacement over time is its average velocity. When calculating an object's actual speed, we divide the distance traveled by the time passed. We are aware that velocity is a vector quantity, and we can calculate the average velocity by dividing the displacement by the time.

How can I calculate the average velocity?

Actual velocity is determined by dividing the overall distance you went by the total duration, while average velocity is determined by dividing the total distance you traveled by the whole time.

Using these values, we can calculate the heat flow as follows:

Q = m * cp * ΔT

First, we need to convert the airflow rate from CFM (cubic feet per minute) to SI units of mass flow rate (kg/s).

\(2000 CFM = 944.9 L/s\) (liters per second)

\(944.9 L/s * 1.225 kg/ m^{3}= 1156.5 kg/s\)

Answer:

I = 0.75 Amp

Explanation:

Ohm's Law

Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points. The constant of proportionality is called the Resistance (R) of the conductor.

The formula can be expressed as:

V = I.R

The intensity of the current through a resistor can be calculated by solving the equation for I:

\(\displaystyle I=\frac{V}{R}\)

A flashlight bulb is an example of a resistor with the specific task to emit light when it's hot enough.

The potential difference (or voltage) is V=6 V and the resistance is R=8Ω, thus the current is:

\(\displaystyle I=\frac{6~V}{8~\Omega}\)

I = 0.75 Amp

Where:

\(\vec F_{1}\), \(\vec F_{2}\), \(\vec F_{3}\) - External forces exerted on the ring, measured in newtons.

\(\vec O\) - Vector zero, measured in newtons.

If we know that \(\vec F_{1} = (70.711,70.711)\,[N]\), \(\vec F_{2} = (-126.859, 46.173)\,[N]\), \(F_{3} = (F_{3,x},F_{3,y})\) and \(\vec O = (0,0)\,[N]\), then we construct the following system of linear equations:
