Answer: A proton is a positively charged particle located in the nucleus of an atom.
To solve the problem it is necessary to apply conservation of the moment and conservation of energy.
By conservation of the moment we know that

Where
M=Heavier mass
V = Velocity of heavier mass
m = lighter mass
v = velocity of lighter mass
That equation in function of the velocity of heavier mass is

Also we have that 
On the other hand we have from law of conservation of energy that

Where,
W_f = Work made by friction
KE = Kinetic Force
Applying this equation in heavier object.






Here we can apply the law of conservation of energy for light mass, then

Replacing the value of 

Deleting constants,


Answer:
The resultant velocity of the plane relative to the ground is;
150 kh/h north
Explanation:
The flight speed of the plane = 210 km/h
The direction of flight of the plane = North
The speed at which the wind is blowing = 60 km/h
The direction of the wind = South
Therefore, representing the speed of the plane and the wind in vector format, we have;
The velocity vector of the plane = 210.
The velocity vector of the wind = -60.
Where, North is taken as the positive y or
direction
The resultant velocity vector is found by summation of the two vectors as follows;
Resultant velocity vector = The velocity vector of the plane + The velocity vector of the wind
Resultant velocity vector = 210.
+ (-60.
) = 210.
- 60.
= 150.
The resultant velocity vector = 150.
Therefore, the resultant velocity of the plane relative to the ground = 150 kh/h north.
d. both a and b
Explanation:
Seismic waves are both transverse and compressional or longitudinal waves.
A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.
- Seismic waves are both longitudinal and transverse waves.
- There are two main types of seismic waves which are the surface and body waves.
- The surface waves runs on the earth surface. These are the rayleigh and love waves.
- The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
- Body waves moves within the earth surface. They are p-waves and s-waves.
- P-waves are longitudinal or compressional waves that propagates within the earth surface.
- S-waves are transverse waves that moves perpendicularly to their direction of propagation.
