Answer:
Gravity is dependent on the mass of two bodies and the distance between them. There is a strong gravitational attraction between Earth and the Moon because they’re relatively close to one another. There is a strong gravitational attraction between Earth and the Sun because the Sun is so massive
Answer:
1885.2 ohms
Explanation:
Step one:
given data
L=5H
f=60Hz
Required
The inductive reactance of the inductor
Step two:
Applying the expression
XL= 2πfL
substitute
XL=2*3.142*60*5
XL=1885.2 ohms
Answer:
Explanation:
If you add or subtract a proton from the nucleus, you create a new element. If you add or subtract a neutron from the nucleus, you create a new isotope of the same element you started with. In a neutral atom, the number of positively charged protons in the nucleus is equal to the number of orbiting electrons.
Answer:
The maximum value of the magnetic field in the wave is 
Explanation:
Given that,
Average value of pointing vector = 0.724 W/m²
We need to calculate the magnetic field
Using formula of pointing vector
The average value of pointing vector
We know that,
Put the value of 
in equation (II)
substitute the value in the formula
The maximum value of the magnetic field in the wave is
It caused the balloons to turn into physical energy
