Answer:
Correct answer is 2B
Explanation:
The electric field magnitude and magnetic field magnitude in an electromagnetic waves are related as under

where 'c' is velocity of light in the medium of transmission
According to the given question if we double the electric field we have

Thus the magnetic field also doubles
Answer:
V = 5.83 m/s
Explanation:
Given that,
Mass of a ball of a clay, m = 2 kg
Initial speed of the clay, u = 35 m/s
Mass of a box, m' = 10 kg
Initially, the box was at rest, u' = 0
We need to find the velocity of the box after the collision. Let V be the common speed. Using the conservation of momentum to find it.

So, the velocity of the box after the collision is equal to 5.83 m/s.
Since Monique is able to hear the heartbeats of her baby, it's the Fetus stage of pregnancy when the body starts developing inside the womb.
<u>Explanation:</u>
The Fetus Stage of Pregnancy:
Once the 4th-7th weeks of pregnancy passed, the embryo start developing inside the womb of the mother and the respective symptoms reflects. This is the Fetus stage of pregnancy which occur in approximately around the 10th week of pregnancy.
In the fetus stage, the human body begins to develop inside the womb. In this phase, most of the organs are developed and the limbs starts to form firmly. The Fetus stage comes after the Embryo stage but usually, the transition varies according to the growth and circumstances of the atmosphere.
But, what is certain is that the mother can feel the impulse and heartbeats of the baby inside her womb which is an exciting and memorable feeling for her.
When heat is applied to a substance/material or steel in our case, a series of changes will occur, one of which is Expansion.
Hence the hole will expand from 1cm to a diameter that is greater.
Thermal expansion refers to the expansion or contraction of the dimensions of the solid, liquid or gas when their temperature is changed.
<h3>Types of Expansion</h3>
- Linear expansion
- Areal expansion and
- Volumetric volume.
