Answer:

The angular acceleration of CD player is $13.93\ rad/s^2$ .

Explanation:

Initial angular speed of a CD player is 0 and final angular speed is 41.8 rad/s. Time to change the angular speed is 3 s.

It is required to find the angular acceleration. The change in angular speed of the CD player divided by time taken is called its angular acceleration. It can be given by :

$a=\dfrac{\omega_f-\omega_i}{t}\\\\a=\dfrac{41.8-0}{3}\\\\a=13.94\ rad/s^2$

So, the angular acceleration of CD player is $13.93\ rad/s^2$ .

irina [24]

Answer:

110 g

Explanation:

q = mCΔT

where q is heat, m is mass, C is specific heat capacity, and ΔT is change in temperature.

Given q = 250 J, C = 0.228 J/g/°C, and ΔT = 10.0 °C:

250 J = m (0.228 J/g/°C) (10.0 °C)

m = 110 g
