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


144 = 16 + 4s
s = 32 rads
d) 32.0rad.

Considering the frequency of 2,450 MHz, the wavelength of microwave oven radiation is about 12 cm and the quantum energy of a microwave photon is about 1 x 10-5 eV.
The mutual forces of gravity between the Earth and an object on or near
its surface are (<em>mass of the object</em>) x (<em>acceleration of gravity on Earth</em>).
These two forces are equal, and we call their strength the "weight" of
the object. It's the number shown on the scale as long as nobody has
their thumb on the scale. In this problem, the force is 45N . (That's
about 10.12 pounds.)
The acceleration of gravity on Earth is about 9.8 meters per second² .
So 45N = (mass in kilograms) x (9.8 meters per second²)
Divide each side by 9.8 : Mass = 45/9.8 = <u>4.59 kilograms</u> (rounded)
