Answer:
here on the surface of moon the gravity decreases so the frequency of oscillation will also decrease
Explanation:
As we know that frequency of oscillation of the simple pendulum is given as
here we know
g = acceleration due to gravity at the surface of the planet
L = length of the pendulum
Now we know that the pendulum is on the surface of earth then gravity is given as
now when same pendulum is taken to the surface of the moon then we have
so here on the surface of moon the gravity decreases so the frequency of oscillation will also decrease

I pretty sure this the answer your looking for
Kinetic energy = (1/2) (mass) (speed)²
The rock's kinetic energy is not
(1/2) (4 kg) (10 m/s)²
= (1/2) (4 kg) (100 m²/s²)
= 200 Joules .
It may be more, or it may be less. The only thing
we can be sure of is that it is not 200 Joules.
Answer:
32 pounds
Explanation:
The amount of water in the 200 pound person is
200 * 60% = 200*0.6 = 120 pounds
Of the 120 pounds, a third of this is extracellular fluid, the amount of extracellular fluid is
120 / 3 = 40 pounds
20 % of this is in the blood, which amounts to
40 * 20% = 40 * 0.2 = 8 pounds
The rest is interstitial fluid, which is
40 - 8 = 32 pounds
Momentum of the bullet is m×v = 0.01 kg × 800 m/s = 8 kgm/s
so momentum of baseball also= 8 kgm/s
8= mass of baseball × velocity
8= 0.145 × v
on solving for v,
v= 55.17 m/s which is the required velocity
