What is the difference between heat temperature and thermal energy?

1 answer:

4 0

Well Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat. While <span>Heat energy (or thermal energy or simply heat) is defined as a form of energy which transfers among particles in a substance (or system) by means of kinetic energy of those particles. In other words, under kinetic theory, the heat is transferred by particles bouncing into each other.</span>

Starting fom rest, a car accelerates at a constant rate, reaching 88 km/h in 12 s. (a) What is its acceleration? (b) How far doe

JulsSmile [24]

Answer:

(A) $a=2.0.37m/sec^2$

(B) s = 146.664 m

Explanation:

We have given car starts from the rest so initial velocity u = 0 m /sec

Final velocity v = 88 km/hr

We know that 1 km = 1000 m

And 1 hour = 3600 sec

So $88km/hr=88\times \frac{1000}{3600}=24.444m/sec$

Time is given t = 12 sec

(A) From first equation of motion v = u+at

So $24.444=0+a\times 12$

$a=2.0.37m/sec^2$

So acceleration of the car will be $a=2.0.37m/sec^2$

(b) From third equation of motion $v^2=u^2+2as$

So $24.444^2=0^2+2\times 2.037\times s$

s = 146.664 m

Distance traveled by the car in this interval will be 146.664 m

A white dwarf in a binary system suddenly flares, but in a few months it settles back to its original luminosity. This process m

Anvisha [2.4K]

Answer:

A Pulsar

Explanation:

Such white dwarf is a Pulsar (from pulsating star). Three main features we find in this kind of celestial body

1. Incredibly high density, in a pulsar there is not what we can define as free interspace. Everything is mass

2.- Huge rotational speed (more than hundreds of kilometer) spinning at more than hundreds of kilometer per second

3.-Intense magnetic field

Combinations of thse features make pulsar emits important amount of energies with pricese periods of time. And if on earth we look a jet of electromagnetic radiation with a precise rigurosity (at pricese period of time) is because we are looking a pulsar spinning and each time the radiation appears is a turn of the pulsar

A person wants to determine the spring constant of an exercise stretch cord. He pulls the cord with a force probe that exerts a

amid [387]

Answer: 180N/m(to 2 significant figures)

Explanation:

According to hooked law which states that the extension of a material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically, F = ke where;

F is the applied force in newtons

k is the elastic/spring constant in N/m

e is the extension in meters

Given applied force = 35N

extension = 20cm = 0.2m

Since F = ke,

k = F/e = 35/0.2

k = 175N/m

The spring constant is 175N/m

= 180N/m (to 2significant figures)
