Answer:
The mass of the copper is 3.00kg
Explanation:
Answer:
the weight of the object, the force of gravity acting on said object, and the mass of the object are needed for Newton's second law of motion.
Answer: a) 0.11 Amp b) 0.000429 Joules c) 0.000514 watt
Explanation:
a)current
I=V/r I=6.0/550 =1.1*10^-2 A
b) energy
E= 1.1*10^-2 x (6.0) x 0.00065s(<-- remember to convert ms to seconds) = 0.000429J
C) Average power
P = (0.000429 x 72) / 60
P = 0.000514 W
Answer:
It is nutrients you get from food
The energy in a photon is given by the formula, E=hf
Where h(plank constant)=6.63×10∧-34Js and
f = frequency of the photon
So the energy of the photon is;
E=(6.63×10∧-34) × (6.0×10∧20)
= 3.978×10∧-13J
