Conservation of momentum requires that the sum of momenta after is equal to that before. Since initially nothing is moving, the sum after the shot will also add to zero.
m₁v₁ = -m₂v₂
Solve for the cannon's velocity v₁
v₁ = -m₂v₂/m₁ = -2.10m/s
The negative sign means it's moving 2.10m/s south.
Lactic acid fermentation. hope this helps :)
Answer:
A. A coil of wire with current running through it
Option (d) is correct.
Explanation:
centripetal acceleration = a = r ω²
r= radius= 10 cm= 0.1 m
ω= angular velocity
9800= (0.1) ω²
ω=313 rad/sec
ω= 313 rad/s * (1 rev/2π rad)
ω=49.8 rev/s
If you take a fluid (i.e. air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is<span><span> not heated.</span> </span>
