Answer:
i'm pretty sure it is alternative sources of energy.
Explanation:
Answer:
V = 5 Volts
Explanation:
Given the following data;
Work done = 20 Joules
Charge = 4 Coulombs
To find the potential difference;
Mathematically, the work done in moving a charge is given by the formula;
W = qv
Where;
W is the work done
q is the quantity of charge
v is the potential difference
Substituting we have;
20 = 4 * v
V = 20/4
V = 5 Volts
Aggregat 4, Aggregat 4, Aggregat 4, Aggregat 4,
Answer:
a) 20.54 J
b) 30.97 J
c) 10.43 J
d) -20.54 J
Explanation:
m = Mass
g = Acceleration due to gravity = 9.81 m/s²
h = Height
Work done by the ball's weight is 20.54 J
Gravitational potential energy of the basketball, relative to the ground, when it is released is 30.97 J
Gravitational potential energy of the basketball, relative to the ground, when it is released is 10.43 J
Change in gravitational potential energy
Change in gravitational potential energy is given by -20.54 J
