Through what angle does it turn during that time interval if the angular acceleration is constant: 32.0rad.

<h3>What is angular acceleration?</h3>
  • Angular acceleration is the term used to describe the temporal pace at which angular velocity varies. Radians per second is the accepted unit of measurement. Consequently, = d d t. Angular acceleration is also known as rotational acceleration.

  • Angular acceleration can be calculated by dividing the angular velocity by the acceleration duration. (t). Use pi instead, or the drive speed (n) divided by the acceleration time (t) multiplied by 30. The usual SI unit for the rotational acceleration that results from this equation is radians per second squared (Rad/sec2).

Through what angle does it turn during that time interval if the angular acceleration is constant:

v(initial) = 4rad/s

v(final) = 12

t = 4 sec

a = ?

v(final) = v(initial) + at

12 = 4 + a(4)

a = 2 rad/sec2

s = ?

v(initial) = 4rad/s

v(final) = 12

a = 2rad/sec2

v(final)^2 = v(initial)^2 + 2as

12^2 = 4^2 + 2(2)(s)

144 = 16 + 4s

s = 32 rads

d) 32.0rad.

An ac power generator produces 73.37 a (rms) at 4623 v. the voltage is stepped up to 105,033 v by an ideal transformer, and the
evablogger [386]

Step up transformer is a device which is used to step up the voltage which is input with some value.

This is based upon the principle of mutual inductance and in this the voltage input and voltage output is different because of number of turns.

Here if ideal transformer is given then power input and power output of the transformer must be same as there is no power loss in ideal transformer.

So we can write

i_pV_p = i_sV_s

here

i_p = 73.37 A

V_p = 4623 V

V_s = 105033 A

now using above equation we will have

73.37*4623 = 105033*i_s

solving above we will have

i_s = 3.23 A

Answer:

1, When Jane brakes, the brakes slow the car wheels turning and the road surface exerts a backwards force on the tires, causing the car to decelerate. The pocket book tends to continue on in a straight line (Newton's first law). If she brakes hard enough that the friction between the book and the car seat is insufficient to decelerate the book as fast as the car is decelerating, the book will slide off the seat, and gravity pulls it to the floor

2.

When the diver uses his / her force to depress the springboard, the springboard pushes him back with equal force
