we know that momentum is given as
P = mv
where P = momentum , m = mass , v = velocity
taking derivative both side relative to "t"
dP/dt = v (dm/dt)
we know that : dP/dt = F = force
hence
F = v (dm/dt)
given that :
dm/dt = rate of mass expelled = 1500 kg/s
v = velocity = 4 x 10⁴ m/s
hence , inserting the values in the above formula
F = (4 x 10⁴) (1500)
F = 6 x 10⁷ N
Answer:
hm my mom said the net force changes
Answer:
The Moon rotating around Earth and the Earth rotating around the Sun
Explanation:
<span>the sun raises the temperatures of molecules inside the balloon. As the molecules receives more kinetic energy, they move apart from each other and expand in volume. Depend on the balloon's material, it might not be strong enough to handle the pressure exerted by the gas inside, and the balloon will pop.</span>
