A car starts from rest and accelerates at a constant rate after the car has gone 50 m it has a speed of 21 m/s what is the accel

Leya [2.2K]

Answer:

4.41 m/s^2

Explanation:

(v_f)^2 - (v_i)^2 = 2a * change in distance

(21)^2 - (0)^2 = 2a * 50

a = (21^2)/(2*50)

a = 4.41 m/s^2

A lens has a focal length of 0.1 m .Find the image distance when the object distance is

Black_prince [1.1K]

Answer:

A) 0.125 m (the image is real)

B) -0.4 m (the image is virtual)

Explanation:

For both situations we will use the <u>Lens Equation</u>:

$\frac{1}{f}=\frac{1}{v}+\frac{1}{u}$ (1)

Where:

$f=0.1 m$ is the focal length

$u$ is the distance between the object and the lens

$v$ is the distance between the image and the lens

Isolating $v$ :

$v=\frac{uf}{u-f}}$ (2)

Knowing this, let's begin with the answers:

A) When $u=0.5 m$

$v=\frac{(0.5 m)(0.1 m)}{0.5 m-0.1 m}}$

$v=0.125 m$ The image is real

B) When $u=0.08 m$

$v=\frac{(0.08 m)(0.1 m)}{0.08 m-0.1 m}}$

$v=-0.4 m$ The negative sign indicates the image is virtual

Suppose that you wish to construct a simple ac generator having 64 turns and an angular velocity of 377 radians/second (this is

Trava [24]

Answer:

$\epsilon_{max} =12.064\ V$

Explanation:

Given,

Number of turns, N = 64

angular velocity, ω = 377 rad/s

Magnetic field, B = 0.050 T

Area, a = 0.01 m²

maximum output voltage = ?

We know,

$\epsilon_{max} = NBA\omega$

$\epsilon_{max} = 64\times 0.05\times 0.01\times 377$

$\epsilon_{max} =12.064\ V$

The maximum output voltage is equal to 12.064 V.
