Answer:
v0 = 24.42 m/s (Approx)
Explanation:
Given:
Increase in frequency = 7.1% =
Computation:
Assume n = 100%
n1 = [(v+v0)/(v+v1)]n
[100 + 7.1] = [(344+v0)/(344+0)]100
107.1 = [(344+v0)/(344)]100
v0 = 24.42 m/s (Approx)
<span>Well, ice is NOT more compressed than water.
Ice molecules do NOT have more charge than water molecules.
Water does NOT have a lower temperature than ice.
But water molecules DO move around more easily than ice molecules</span>
Answer:
22 N applied force
Explanation: Since they are both pushing the wagon in the same direction the force adds up.
Answer:
Axis rotation to determine the length of a day
Explanation:
The length of time it takes a planet to complete one full rotation on it's axis is what we would measure as being one day. On Earth, it takes slightly less than 24 hours to rotate on its axis and this is one day.
Answer:
a) P1+P2
Explanation:
The magnitude of their combined momentum is just the addition of each momentum, because in this case of inelastic collision, the kinetic energy of the two cars are both converted to some form of energy because the velocity of both cars becomes zero, i.e., V=0, making P = mv = 0, this means the magnitude of P1 + P2 = 0.
