<u><em>Answer:</em></u>
Momentum of the skier is 350 Kg.m/sec
<u><em>Explanation:</em></u>
<u>Momentum of a body can be calculated using the following rule:</u>
P = m * v
<u>where:</u>
P is the momentum of the body
m is the mass of the body given as 70 Kg
v is the velocity of the body given as 5 m/sec
<u>Substitute with the givens in the above rule to get the momentum of the skier as follows:</u>
P = m * v
P = 70 * 5
P = 350 Kg.m/sec

The motion of particles to one side of the rest position will be the same as the motion of the other side of the rest position in a wave motion. because in a wave motion or wave function, it symmetrical. meaning the motion on the other side will be identical to the other side of the rest position
Answer:
Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion. Hence why they can be distinguished. Have a good day
Answer:
6.82%
Explanation:
If 44 ±3 beats are counted in 30 seconds, twice the number of beats will be counted in 1 minute or 60 seconds, i.e. 88 beats per minute. The absolute uncertainty in 1 minute will also be twice the uncertainty in 30 seconds, so 88 ±6 beats per minute.
The percentage uncertainty can be found by below:
The percentage uncertainty can also be found for the 30 second interval
While the absolute uncertainty varies depending on the time interval, the percentage uncertainty remains the same: 6.82%
