A
longitudinal wave is a mechanical wave that causes the medium to vibrate
parallel to the direction of the wave. Its wave’s forces travel through
multiple rarefactions and compressions where compression is the closest
distance in the longitudinal wave and rarefaction is the farthest distance
apart in the said wave.
Power = energy/time=20/4=5.0
According to cuneiform tablets in the ancient world, straight lines cannot cross, and no motion in the world is not relative. Btw...I KNOW!!! GOT MILK???
Answer
given,
force = 94 lb
weight of crate = 220 lb
Assuming the static friction be equal = 0.47
kinetic friction = 0.36
Maximum force applied to move the object is when object is just start to move.
F = μ N
F = 0.47 x 220
F = 103.4 lb
As the frictional force is more than applied then the object will not move.
so, the friction force will be equal to the force applied on the object that is equal to 94 lb.
hence, the direction of force will left.
