Answer:
11.4m/s I think mb not 100% lol
Explanation:
P=mv
P1 = 1200×60 = 72000
P2 = 3000×40 = 120000
120000+(-72000) = 48000
v=P÷m
m=1200+3000 = 4200
48000÷4200 = 11.4m/s
Answer:
Air
Explanation:
The mixing of cooler air in the lower troposphere with air flowing in a different direction in the middle troposphere causes the rotation on a horizontal axis, which, when deflected and tightened vertically by convective updrafts, forms a vertical rotation that can cause condensation to form a funnel cloud.
Answer:
When a ray of light passes from a denser material into a less dense material it is bent towards the surface between the two materials. This means that in this situation the angle of refraction is always greater than the angle of incidence. ... They also apply to light passing through lenses
Yes ,you can work output exceed work input
