Answer:
B and C
Explanation:
Both of them have to do with the ocean which was mentioned
Explanation:
Momentum is mass times velocity.
p = mv
720 kg m/s = m (5 m/s)
m = 144 kg
The Olympic sport of curling is one that is practically designed to show Physics in motion. Curling is a sport in which two teams alternate sliding smoothed stone pucks down an ice rink court with the intent to seat their stone closest to the center of the target (called the house). Each team has eight stones, meaning that the team that goes second has the (could be) massive advantage of sending the last stone.
The mass of the stone is important in that the more massive a stone (m) and the speed at which it travels (v) dictates it's momentum (momentum=mxv). As the curling stone slides down the ice (which is relatively frictionless unless acted upon by other players or objects) and having inertia, continues in it's straight course (again, unless acted upon by outside forces). If the stone hits another stone, it transfers some of its momentum in an elastic collision to that stone and the original stone is deflected in a calculable manner.
Collisions are used in the game to either clear opponent's stones from the house or out of their defensive positions, or to make adjustments to one's stones present in the house, all based on the momentum of the moving stone, and its transference.
Answer:

Explanation:
From the question we are told that:
RF source oscillation speed 
The external field
.
Pro- ton magnetic moment component 
Generally the equation for magnitude of
is mathematically given by




Answer:
1. Speed=0
2. 2.46 s
3.30.1 m
4. 22.0 m
5.1.004 s
Explanation:
We are given that
Initial speed of blue ball, u=24.1 m/s
Height of blue ball from ground y_0=0.5 m
Initial speed of red ball , u'=7.2 m/s
Height of red from ground=y'0=32 m
Gravity, g=
1.When the ball reaches its maximum height then the speed of the blue ball is zero.
2.v=0

Using the formula and substitute the values

Where g is negative because motion of ball is against gravity


3.
Using the formula


4.Time of flight for red ball=3.77-2.9=0.87s


Hence, the height of red ball 3.77 s after the blue ball is 22.0 m.
5.According to question






Hence, 1.004 s after the blue ball is thrown are the two balls in the air at the same height.
