Answer:
The radius described the proton moving is
r=3.91mm
Explanation:
The magnetic field that moving the proton with the velocity
v=15 km/s
To find the radius combinate the magnetic field with the mass of the proton and the charge of the proton
r = mv=eB
r = mv/eB
r = 3.9mm
Significant
Explanation:
All the digits shown on a measuring device and one estimated digit are all considered to be significant.
A significant digit is a set of values that shows how precise a measurement is reported.
Measuring devices such as calculators gives their values in significant digits.
- Non- zero digits in a measurement are always significant.
- Zero's before a decimal are not significant. Those after a number in a decimal are significant.
- Zero's between digits are significant.

Answer:
B. silicate rocks and metals
Answer:
Decrease
Explanation:
Working at a constant temperature when more pressure is exerted, the volume decreases.
This is known as Boyle's law.
According to Boyle's law;
"the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states.
Answer:
The magnitude of their velocities will be the same but their direction will be reversed.
