Answer:
Acceleration:
C. Meters per second squared
Velocity:
B. Meters per second
Distance:
A. Meters
Explanation:
We must remember that the international system of measures (SI) takes into account for the length as the main unit the meter, for the mass the kilogram, for the time the second.
The acceleration is calculated using the following expression
a = v/t = (m/s/s) = (m/s^2]
The velocity is calculated using the following expression
v = x/t = (m)/(s) = (m/s)
The distance for the SI system is given in meters
Answer:b
Explanation:
velocity of a falling object increases.
so Kinetic energy of a falling object increases
height of a falling object from the ground decreases.
so the potential energy of a falling object decreases
-- The amount of energy radiated by the sun is not affected at all by how much
of it we use or don't use.
-- The sun is not expected to quit shining on us, or to change its rate of energy
output, at any time within the next several many human lifetimes.
Solar energy is going to keep arriving here, continuously, at the same rate,
free of charge, for a long long time, whether we feel like using it or not. It's
the closest thing to manna from heaven that has been seen around here for
thousands of years.
Answer:
electrons
Explanation:
The total charge Q is the sum of the charge of the N electrons contained in the sphere:
charge of a electron
We solve to find N:
The time measured is 25 seconds. The error in the measurement is 0.2 seconds. The % error is therefore
(0.2/25)x100 = 0.8%.
The period of one oscillation is 25/20=1.25 seconds. The error in the period is 0.8/100 x 1.25 = 0.01 second.

ie period = 1.25 +/- 0.01 s.
