What is latent heat energy's definiton

Physics
1 answer:
tamaranim1 [39]3 years ago
6 0
The heat energy which has to be supplied to change the state of a substance is called its latent heat. Latent heat does not increase the kinetic energy of the particles of the substance, so the temperature of a substance does not rise during the change of state. :))

Explain in terms of energy how dissipative forces such as friction reduce the amplitude of a harmonic oscillator. Also explain h
miss Akunina [59]

Answer:

There is the conservation of energy in a harmonic oscillator. As a result, the system amplitude will remain constant. The dissipative forces (i.e. friction) lead to loss of energy in different forms and the system amplitude is reduced due to the reduction in both kinetic and potential energies at the end of each oscillation.

The external forces acting on a driving mechanism must be accounted for at all times. In this case, there is a loss of energy because dissipative forces can be returned back to the system in the presence of the driving to account for the loss in energy.

Below, the two-way table is given for a class of students. Freshmen Sophomore Juniors Seniors Total Male 4 6 2 2 Female 3 4 6 3
julsineya [31]

The required probability is 3/4.We have to compute the probability

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.Juniors=2+6=8

<h3>What is the probability?</h3>

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8=3/4

Therefore, the required probability is 3/4.

Heat rash is caused by chemical exposure Truth or false
Harrizon [31]

Answer:

This is false.

Explanation:

Heat rash develops when some of your sweat ducts clog. Instead of evaporating, perspiration gets trapped beneath the skin, causing inflammation and rash. Heat rash is usually self-limited, meaning it resolves on its own without treatment. Over-the-counter treatments such as calamine, hydrocortisone cream, itch preparations (such as Benadryl spray), or sunburn lotions can be used as skincare to treat the itching and burning symptoms. Heat rash usually goes away on its own within three or four days so long as you don't irritate the site further. Heat rash happens when the sweat glands get blocked. The trapped sweat irritates the skin and leads to small bumps.
