Answer:
Magnetic force, 
Explanation:
It is given that,
Velocity of proton, 
Angle between velocity and the magnetic field, θ = 53°
Magnetic field, B = 0.49 T
The mass of proton, 
The charge on proton, 
The magnitude of magnetic force is given by :



So, the magnitude of the magnetic force on the proton is
. Hence, this is the required solution.
Power = Work/Time =(Force* Displacement)/Time
Power = (100N* 10m)/10s = 100 Watts
Answer:
they are all involved in our daily lives
Explanation:
Given :
You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you travel 250 miles in an hour and a half.
To Find :
Average speed.
Solution :
We know, average speed is given by :

Therefore, average speed of the journey is 100 miles/hr.
Hence, this is the required solution.
Shock waves can be observed in outer space between planets where there is very little matter. Although little, plasma does exist in outer space which allows the waves to travel.
