Answer:
2.76×10⁻¹⁰ C
Explanation:
Applying,
V = W/q................... Equation 1
Where V = Electric Potential, E = Electric potential energy, q = charge.
make q the subject of the equation
q = W/V................ Equation 2
From the question,
Given: W = 4.26×10⁻⁸ J, V = 154.5 V
Substitute these values into equation 2
q = 4.26×10⁻⁸/154.5
q = 2.76×10⁻¹⁰ C
Prior to the discovery and elaboration of Copernicus with the theory of heliocentricism, which states that the sun is the center of the universe and that the planets orbit around it in a circular manner. The theory of geocentrism was first published by another astronomer and philosopher, Ptolemy. As a custom in the early years of the society, people already stood for the idea that the earth is the center of the universe which is easy to believe at that time given that their perspective shows that the sun moves when observed from earth's atmosphere.
Velocity is not changing.
Acceleration is zero.
Net force is zero.
Answer:
80 N
Explanation:
From the question,
F = ma .......................... Equation 1
Where F = Force, m = mass of the object, a = acceleration of the object.
make m the subject of the equation
m = F/a.................... Equation 2
Given: F = 24 N, a = 3 m/s²
Substitute into equation 2
m = 24/3
m = 8 kg.
If the acceleration of the object becomes 10 m/s²,
Substitute into equation 1
F = 10(8)
F = 80 N.
