The different types of energy transfers are convection, conduction, and radiation.
I'm not too sure on the second one but thermodynamics relates thermal energy, kinetic energy, and potential energy. I'm basing this on the formulas of the laws of thermodynamics, but it could also be temperature, heat, or work.

Summarize how the components of health are related to wellness.

skelet666 [1.2K]

Answer:

there are 5 main aspects of personal health: physical, emotional,social,spiritual, and intellectual.

physical weelness indicates a high levelnof endurance, flexibility and strength. it incorporates daily exercise through cardiovascular and muscular activities.

mental or emotional wellness focuses on an acceptance and afreement with one's emotions and feelings. A person need to reach a high level of self-respect and dignoty.

lifestyle wellness doesn't have a definite, agreed upon route or direction for accomplishment. lifestyle wellness incoporates many different dimentions of wellness. but deals mostly with having a balanced lifestyle. every person has a different idea of what a balanced idea includes.

intellectual wellness encourages us to engage in creative and mentallu-stimulating activities. these activities should expand ur knowledge and skills while allowing you to share ur knowledge and skills with others. intellectual knowledge includes learning. its important to explore new ideas and understanding in order to become more mindful and better-rounded. having an optimal level of intellectual wellness inspires exploration. also stimulates curiosity.

A proton travels with a speed of 1.8×106 m/s at an angle 53◦ with a magnetic field of 0.49 T pointed in the +y direction. The ma

Likurg_2 [28]

Answer:

Magnetic force, $F=1.12\times 10^{-13}\ N$

Explanation:

It is given that,

Velocity of proton, $v=1.8\times 10^6\ m/s$

Angle between velocity and the magnetic field, θ = 53°

Magnetic field, B = 0.49 T

The mass of proton, $m=1.672\times 10^{-27}\ kg$

The charge on proton, $q=1.6\times 10^{-19}\ C$

The magnitude of magnetic force is given by :

$F=qvB\ sin\theta$

$F=1.6\times 10^{-19}\ C\times 1.8\times 10^6\ m/s\times 0.49\ Tsin(53)$

$F=1.12\times 10^{-13}\ N$

So, the magnitude of the magnetic force on the proton is $1.12\times 10^{-13}\ N$ . Hence, this is the required solution.

1. Elastic potential energy (D. EEl)

In this situation, the spring is compressed with the toy on top of it. The toy is stationary, so it does not have kinetic energy. However, the spring is compressed, so it does have elastic potential energy, given by:

$E_{EL}=\frac{1}{2}kx^2$

where k is the spring constant and x is the compression of the spring.

2. Gravitational potential energy (C. Eg)

In this situation, the spring has been released, so it returns to its natural position, so its elastic potential energy is zero. The toy is also stationary, since it is at its top position, where its velocity is zero, so its kinetic energy is also zero. However, the toy is now at a certain height h above the spring, so it has gravitational potential energy given by:

$E_g = mgh$

where m is the mass of the toy and g is the gravitational acceleration.

3. Gravitational potential and kinetic energy (A. Eg and EK)

In this situation, the toy is falling: so, it is moving with a certain speed v, so it has kinetic energy given by

$E_k = \frac{1}{2}mv^2$

Also, since it is at a certain height above the spring, it still has some gravitational potential energy, as in the previous point.

4. Gravitational potential energy (C. Eg)

The jumper is standing on the bridge, so it has gravitational potential energy given by its height h above the ground:

$E_g=mgh$

where m is the mass of the jumper.

5. This exercise has the same text of the previous one.

klasskru [66]

Answer:

If you punched thousands of holes in the aluminum foil, you would see thousands of small images in the viewer.

Explanation:

If thousands of holes is punched/perforated in an aluminum foil, such that there were more holes than foil.

Thousands of small images would be formed, which can be seen in the viewer. Aluminum foil has a good reflective property which allows the thousands of holes punched to reflect equal number of images, although the images are smaller in size than the original image size.
