Answer:
in the ball
Explanation:
potential energy is where an object has energy, always, but it isn't always moving, and when you drop the ball, it has kinetic energy.
Answer:
Force on the proton will be 
Explanation:
We have given speed of proton is 20.3% of speed of light
Speed of light 
So speed of proton 
Magnetic field B = 0.00629 T
Charge on proton 
Angle between velocity and magnetic field 
Force on the proton is equal to 
Answer: Thermal energy is 8,2 kJ
Explanation: Heat Q = m c ΔT . c = 385 J/kg C and
ΔT = (1085 - 25)C = 1060 C. Q = 0.020 kg · 385 J / (kg C) ·1060 C
= 8162 J
Answer:
decrease by a factor 10
Explanation:
The parallax angle of a close star is given by

where
p is the parallax angle
d is the distance of the star from Earth, in parsecs
From the formula we see that the parallax angle is inversely proportional to the distance.
In this problem, the distance of the star is increased by a factor 10:
d' = 10 d
so the new parallax angle would be

So, the parallax angle would decrease by a factor 10.
