Answer:
m = 7.48 kg
Explanation:
force (f) = 11,500 N
length of barrel (s) = 1.7 m
angle above the ground = 49.3 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
initial velocity (u) = 0 m/s
final velocity (v) = 72.3 m/s
mass (m) = ?
force = mass (m) x acceleration (a)
acceleration (a) = force / mass (m)
acceleration (a) = 11500 / m
applying the equation of motion
, we can get the mass

5227.3 = 0 + 
m = 
m = 7.48 kg

Answer: <u>Centrifugal Force </u>
Explanation:
The force that pulls out from the center on a body in circular motion is called centrifugal force and it increases with acceleration. Centrifugal force results in strong outward pull on your vehicle.
The answer is 20 meters would be the water depth started to feel bottom. This is half of the wavelength. The reason behind this is the wave travels half or the partial of the wavelength underneath the surface. For that reason that is where the wave would be starting to feel the ground.
Answer:
Vdc=10V
Explanation:
in a closed loop consisting of a super charged capacitor and an inductor, the super charge capacitor acts as a supply when the loop is closed, at t=0, the emf stored in the capacitor is 10V (q/c); and at that same time Vl= voltage across the inductor or loop too would be 10V,
if the loop remains closed for a longer period, the inductor would absorb energy from the capacitor till it dissipates all charges with itself.
