Efficiency = (Wanted) energy out ÷ energy in × 100
Energy in = 400J
Wanted Energy out = 240J
Energy cannot be used up, only transferred, so the remaining energy is most likely to be transferred into unwanted energy (loss of energy) such as heat energy.
Efficiency = 240 ÷ 400 × 100
Efficiency = 0.6 × 100
Efficiency = 60%
Answer:
ratio =0.3075 T
Explanation:
The magnetic field B creates a force on a moving charge such that
Now this causes a centripetal acceleration
so
...........(i)
...............(ii)
If accelerating potential V is same and then kinetic energy equals the potential energy difference
put these value in equation (ii)
simplifying we get
for same location r will be same in both case
..............(iii)
..........(iv)
dividing (iv) and (iii) equation we get
so on solving we get
=0.3075 T
I believe the answer to be she stopped for 4 mins
The 4 signifies the
atomic weight, and the 2 subscribes the element's
atomic number(aka the number of protons in the atom).
