Answer:
Number of significant figures=3
Explanation:
15.0/124=0.121
In scientific notation 1.21× 10-1
or,
1.21e-1
Answer:
W = 76 N
Explanation:
In this exercise you are asked to find the weight of the body.
Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is
W = g m
where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars
W = 3.8 20
W = 76 N
-Geographic north and south poles are determined by the earth's spin.
-Magnetic north and south is determined by the direction a compass points.

Answer:
a. The stored electric field energy can be greater than the stored magnetic field energy.
b. As the capacitor is discharging, the current is increasing.
d. The stored electric field energy can be less than the stored magnetic field energy.
e. The stored electric field energy can be equal to the stored magnetic field energy.
Explanation:
We know that total energy of capacitor and inductor system given as
L=Inductance ,I =current
C=Capacitance ,V=Voltage
The total energy of the system will be remain conserve.If energy in the inductor increases then the energy in the capacitor will decrease and vice -versa.
The values of stored energy in the capacitor and inductor can be equal ,greater or less than to each other.But the summation will be constant always.
Therefore the following option are correct
a ,b , d , e
Answer:
A decreases while B increases because the equilebrium only reacts to different sphers of this substance.
