What is the relationship between thermal energy and temperature?

1 answer:

6 0

As the air becomes warmer, heat is transferred between molecules and kineticenergy is created which produces thermal energy. As the molecules move faster to transfer heat, the temperature also increases.

Figure 23.9 shows a sliding mass on a spring. Assume there is no friction.

Tom [10]

Without friction, there will be undamped simple harmonic motion. The force of the spring is proportional to the distance from the equilibrium point. The period of oscillation will be independent of the amplitude.

I hope my answer has come to your help. God bless and have a nice day ahead!

The stoplight had just changed and a 2100 kg Cadillac had entered the intersection, heading north at 3.2 m/s , when it was struc

elena55 [62]

Explanation:

It is given that,

Mass of the Cadillac, $m_1=2100\ kg$

Speed of Cadillac, $v_1=3.2\ m/s$ (towards north)

Mass of Volkswagen, $m_2=1100\ kg$

The cars stuck together and slid to a halt, leaving skid marks angled 35 degrees north of east.

According to the law of conservation of momentum,

The momentum along x axis, $m_1v_1=(m_1+m_2)\ usin35$ ............(1)

The momentum along y axis, $m_2v_2=(m_1+m_2)\ ucos35$ ...........(2)

From equation (1) and (2) it is clear that,

$\dfrac{m_1v_1}{m_2v_2}=tan35$

$v_2=\dfrac{m_1v_1}{m_2\ tan35}$

$v_2=\dfrac{2100\times 3.2}{1100\times \ tan35}$

$v_2=8.72\ m/s$

So, the Volkswagen going just before the impact is 8.72 m/s. Hence, this is the required solution.

A car can go from 0 m/s to 38 m/s in 4.5 seconds. If a net force of 6570 N acted on

masha68 [24]

The Mass of the car = 782.1 Kg

The mass of the car is calculated as follows:

Mass = Force/ acceleration

The force on the car = 6570 N

The acceleration of the car, a = 38 - 0/4.5

acceleration = 8.44 m/s²

Mass of the car = 6570/8.44

Mass of the car = 782.1 Kg

In conclusion, the mass of the car is obtained from the acceleration and force on the car.

The product of the frequency and the wavelength of a wave equals the

Svetllana [295]

Answer:

b. speed of a wave

Explanation:

The speed of a wave is defined as the product between the wave's frequency and the wave's wavelength:

$v=\lambda f$

where

$\lambda$ is the wavelength of the wave

f is the frequency

Therefore, we see that this matches the definition listed in choice B:

b. speed of the wave.

The other options are:

a. number of waves passing a point in a second. --> frequency

c. distance between wave crests. --> wavelength

d. time for one full wave to pass. --> period
