Answer:) The answer is D decreasing the radius of the swing.

Explanation:

Decrease the radius of the swing Each swing moves around the perimeter in the same amount of time, but the smaller the radius of the circle the slower the speed.

Answer:

D. Decrease the radius of the swing in the circle

Explanation:

Decreasing the friction on the chain and increasing the radius of the swing in the circle will both increase the speed.

If the angular frequency of the motion of a simple harmonic oscillator is doubled, by what factor does the maximum acceleration

Nataly_w [17]

Answer:

When we double the angular velocity the maximum acceleration $(a_{max})$ will changes by a factor of 4.

Explanation:

Given the angular frequency $(\omega)$ of the simple harmonic oscillator is doubled.

We need to find the change in the maximum acceleration of the oscillator.

$a_{max}=A\omega^2$

Now, according to the problem, the angular frequency $(\omega)$ got doubled.

Let us plug $\omega=2\times \omega$ . Then the maximum acceleration will be $a_{max'}$

$a_{max}=A\omega^2$

$a_{max'}=A(2\times \omega)^2\\a_{max'}=A\times 4\omega\\a_{max'}=4A\omega$

$a_{max'}=4a_{max}$

We can see, when we double the angular velocity the maximum acceleration will changes by a factor of 4.

M)³ / 6 = 4.2e9 m³
so its mass is 
M = 3300kg/m³ * 4.2e9m³ = 1.4e13 kg 
and so its KE at 16 km/s = 16000 m/s is 
KE = ½ * 1.4e13kg * (16000m/s)² = 1.8e21 J

# of bombs N = 1.8e21J / 4.0e16J/bomb = 44 234 bombs
give or take.
