Answer:

E∝A²

Energy varies as square of change in amplitude

If amplitude of 1 has energy of 2

Amplitude of 2 (double of 1) = (2x2)=4x2=8  4 times the energy at amplitude of 1.

For 8 units of amplitude change

8x8=64x2= 128  or C:

andrey2020 [161]

Answer:

w = w₀ / 2    the angular velocity is half the initial value.

Explanation:

We can analyze this exercise as if we added another disk to obtain a disk with twice the mass, for which if the system is two disks, the angular tidal wave is conserved

initial instant.

          L₀ = I₀ w₀

final moment

          L_f = I w

the moment is preserved

          L₀ = L_f

          I₀ w₀ = I w

the moment of inertia of a disk is

         I = ½ m R²

we substitute

          ½ m R² w₀ = ½ (2m) R² w

          w = w₀ / 2

for the case of a disk with twice the mass, the angular velocity is half the initial value.

A net force, the magnitude of which is 2800 n, accelerates a 1250-kg vehicle for 8.0 s. the vehicle travels 80.0 m during
ASHA 777 [7]

The power output is, 2800 watt. Power is defined as the rate of the work done.

<h3>What is force?</h3>

Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

The power output is found as;

\rm P = \frac{W}{t} \\\\ P= \frac{F \times d }{t} \\\\ P= \frac{2800 \ N \times 80.0\ m}{8.0 \ sec} \\\\ P=2800 \  Watt

Hence,the power output is, 2800 watt.

To learn more about the force, refer to the link;
