Answer:
C and D are correct
Explanation:
An electric dipole moment for pair of equal and opposite charges is defines the magnitude of charge times the distance between them and the direction is always towards the positive charge. According to the definition only points C and D are correct.
C) No net force acts on the electric dipole.
D) There are no electric forces exerted on each pole of the dipole.
Answer:
U = 12,205.5 J
Explanation:
In order to calculate the internal energy of an ideal gas, you take into account the following formula:
(1)
U: internal energy
R: ideal gas constant = 8.135 J(mol.K)
n: number of moles = 10 mol
T: temperature of the gas = 100K
You replace the values of the parameters in the equation (1):
The total internal energy of 10 mol of Oxygen at 100K is 12,205.5 J
Answer:
=26.92 m/s
Explanation:
Speed is calculated as a ratio of the total distance covered ( It is directionless) to the total time taken to cover the distance.
Average speed= total distance/total time
=x/t
Total distance from the question= 3500m
Total time taken to cover the above distance = 2×60 +10=130 Seconds
Therefore, average speed= 3500m/130 s
=26.92 m/s
Answer:
Today, scientists believe that the main reason the earth has had periodic ages is that the climate of earth is controlled by the difference in heating of it's surface by the sun. As for example, the equatorial regions are the warmest as the sun is vertically overhead of those areas and the polar regions where the sun is at the extreme angels are the coldest ones.
Explanation:
Answer:
The emf is 0.574 volt.
Explanation:
Given that,
Magnetic field
Length = 75.0 m
Velocity = 255 m/s
We need to calculate the emf
Using formula of emf
Where, v = velocity
l = length
B = magnetic field
Put the value into the formula
Hence, The emf is 0.574 volt.
