<u>Step-by-step</u><u> Explanation</u><u>:</u>
Momentum is given by the product of mass and velocity of any object.
We have:
- Mass of the puck = 0.1 kg
- Velocity of the puck = 55 m/s
Then, Momentum:
= 0.1 kg × 55 m/s
= <u>5.5 kg </u><u>m/s</u> (Ans)
~
Pressure = Force / Area
Put your data in front of yourself.
Force = 600 Newtons
Area = 300 cm^2
Firstly you need to convert the area into m^2 and you do this by diving 300 with 10000.
Now you use the formula:-
Pressure = 600/ 0.03
Which comes out to be 20,000 Pa.
Hope this helps!
Answer:
The expression for the time taken by an object to move with a speed at some distance is,
t=<u> </u><u>d</u><u>/</u><u>v</u>
Here, t is the time taken by the opponent to react, d is the length of the court, andis the speed of the ball.

Hello! Your answer would be D. Interference
This is because interference causes vibration!!!
Answer:
Explanation:
Given
No of logs
diameter of log
Length of log
42 % of log volume(V) is above water when no one is on raft
so 58 % of log volume(V) is submerged in the water
Weight of 14 log
Buoyancy force on 14 logs
as system is in equilibrium so
Specific gravity of log
