Explanation:
It varies with altitude, but at sea level, it's 9.8 m/s².
Since momentum is a vector quantity, take any direction as positive and other as negative. Answer won't change.
Answer:
In the nucleus
Explanation:
You find it in the nucleus. This is where protons and neutrons are. Don't forget the quarks as well ;)

Answer:
The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction
Explanation:
In order to calculate the magnitude and direction of the magnetic field, you take into account the following equation for the magnetic force on the proton:
(1)
v: speed of the proton = 9.9*10^5 m/s
q: charge of the proton = 1.6*10^-19C
B: magnetic field = ?
FB: magnetic force on the proton = 1.6*10^-13N
When the proton travels in the positive y direction (^j), you have that the proton experiences a force in the positive z direction (+^k). To obtain this direction of the magnetic force on the proton, it is necessary that the magnetic field points in the negative x direction, in fact, you have:
^j X (-^i) = -(-^k)=^k
To obtain the magnitude of the magnetic field you use:

The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction
