Explanation:

Answer:

Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.

The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.

Thermal energy is defined as the energy present within an object because of the motion of its particles.

So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.

Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.

Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Which factor has the least effect on the strength of an electromagnet? A. The length of the connecting wires
B. The number of coils of wire.
C. The material of the core.
D. The strength of the battery
​

Answers

The length of the connecting wire has the least effect on the strength of an electromagnet.

What factors influence the strength of an electromagnet?

  • An electromagnet is a type of magnet where an electric current creates the magnetic field. The wire that makes up an electromagnet is typically twisted into a coil.
  • A magnetic field is produced by a current flowing through the wire and is concentrated in the hole, designating the centre of the coil.
  • The type of core material, the strength of the current flowing through the core, the number of wire turns on the core, and the size and form of the core are all factors that determine an electromagnet's strength.
  • Stronger magnetic fields can be created by using alloys like alnico, which is an alloy of aluminium, nickel, and cobalt.

The strength of the electromagnet's magnetic field increases when:

(a) the current increases

(b) the number of turns increases

(c) the wire is wound so that the length of the electromagnet is reduced

(d) Soft iron core inserted into magnetic coil

A plant with round seeds is crossed with another plant with round seeds. Round are dominant over oval seeds. When two heterozygous round-seeded plants are crossed, what is expected of their offspring, assuming random chromosome segregation?

Answers

Because the plants are heterozygous their alleles will be Ss (for example) Therefore if you crossed them over your possible outcome would be SS, Ss, Ss, and ss. Because the round seeds are dominant (shown as the capital S) this means that if the S is shown then the plant will have ROUND seeds. Therefore in this situation 3/4 of all the offspring would have round seeds.

Predatory fish that swim in the water column, usually have what kind of coloration?disruptive
counter shading
cryptic
fusiform

Answers

The answer is counter shading.

Countershading is used by the predatory fishes. It is a form of camouflage in which the animal's pigmentation is darker on the upper side and lighter on the lower side of the body. It made the predators detection from the prey but counterbalancing the effects of self-shadowing.
