Answer:

No electromagnetic waves can not exists if changing magnetic field could produce electric fields but the changing electric fields could not produce magnetic fields. Electromagnetic waves are oscillating waves and they are based on this fact that the changing magnetic field produce electric field and the changing electric field produce the magnetic field. That is why these waves are known for self propagation and can even travel through vacuum. In this wave the electric field and the magnetic field lies perpendicular to each other. These waves travel with the speed of light and their example is light and other radiations coming from sun.

Cerrena [4.2K]

Answer:

the  force exerted by the seat on the pilot is 10766.7 N

Explanation:

The computation of the force exerted by the seat on the pilot is as follows:

F = Mg + \frac{MV^2}{R}\\\\= 70 \times 9.81  + \frac{70 \times 120^2}{100}\\\\= 10766.7 N

Hence, the  force exerted by the seat on the pilot is 10766.7 N

A solenoid of length 5.0 cm has a cross sectional area of 1.0 cm2 and has 300 uniformly spaced turns. The solenoid is wrapped in
OleMash [197]

The calculated mutual inductance is 8.544 x 10⁻⁵ H.

Two coils have a mutual inductance of 1 henry when emf of 1 volt is induced in coil 1 and when the current flowing through coil 2 is changing at the rate of one ampere per second.

Length of the solenoid= 5.0 cm

Area of cross-section=1.0 cm²

no of spaced turns=300 turns

turns of insulated wire=180 turns

Mutual inductance (M) = μ₀μr N1N2 A/ L

                                     =(4xπx 10⁻⁷) x (6.3 x 10⁻³) x 300 x 180 x 1/ 5

                                     =79.12 x 10⁻¹⁰ x 54000 / 5

                                     =8.544 x 10⁻⁵  H

hence, the mutual inductance is 8.544 x 10⁻⁵ H.

*PLEASE HELP! FIRST CORRECT ANSWER GETS BRAINLIEST!*
scoray [572]

Answer:

Explanation:

1 advantage of genetic engineering:

It allows for a faster growth rate. Because with genetic engineering, plants and animals are allowed to be modified so their maturity would occur at a quicker pace.

1 disadvantag of genetic engineering:

The nutrition value of foods can be less. For example, in a research show that genetic enginnering make chicken increase the fat content by 220% but reduced the amount of protein.

1 advantage of cloning:

When cloning, the object would be able to create tissue and organs that doctor can use when needed during the surgery.

1 disadvantage of cloning:

If original organism has genetic deffects, it will be passed down through all the continuous generations

1 advantage of artificial selection (can be called as selective breeding):

It will provide improvements to plants and animals. For example, seedless fruits, increast the tast of food, etc.

1 disadvantage of artificial selection (can be called as selective breeding):

It may lead to a lack of variety in plant or animal species. As the breeding is selective so the variety in plant would be decrease. For example, people like seedless fruits than normal included-seed fruit so that would make the new fruit become more popular and may lead to decrease the diversity in fruits.

Hope this help you :3

Assume that the potential energy of the basketball is 0 J at position E. At which point is the ball's potential energy half of i
Nookie1986 [14]
The potential energy of a body is the maximum at the highest position of that body. So for example, if the maximum position of the ball is at 3 m, there will be the maximum potential energy.

To get the half of the maximum potential energy, the ball should be at the half of the maximum position, which is 1.5 m.
