Dark clothing feels warmer than white clothing on a sunny day. Which interaction causes the dark clothing to feel warm?

Answers

Answer 1
Answer:

Answer: Absorption

Explanation: Because the darker clothing absorbs the heat more than the lighter clothing beacuse of contrast i guess . A P E X

Answer 2
Answer:

Explanation:

The darker the object, the better it emits heat, because it's a better absorber of light. On the other hand, a white object appears white because it reflects all the different wavelengths and absorbs little to no light.

If an object is accelerating to the right , then net force on the object must be directed towards the right ! True Or False ?

Answers

Not so fast.

I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.

If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.

If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.
This is correct. Just think about it. If you push an object to the right then it will accelerate to the right.

What kind of system is generally composed of a fluid system to move the heat from the collector to its point of usage and a reservoir to stock the heat for future use?A.
coal burning
B.
nuclear power
C.
solar heating

Answers

Solar heating is the system composed of a fluid system to move the heat from the collector to its point of usage and a reservoir to stock the heat

Explanation:

The options given here like coal burning uses solid material as the source to heat and to generate energy. Similarly, nuclear power also requires solid particles like atoms or neutrons to strike the moderators forming energy.

In both of these cases, fluid system is present but it is used completely as coolant and to maintain the temperature. Thus, the remaining system that is solar heating has been done for water tanks where the fluid as water is used to move the heat from its collector to its point of usage. Even in solar system it is used as reservoir to stock the heat.

Which of the following is an example of an organism maintaining homeostasis? A.
a boy riding a bike


B.
a cat grooming itself


C.
a bear nursing her cubs


D.
a man sweating while he runs

Answers

Homeostasis is generally maintained by an organism inside the body. Option D is the best example of the given statement.

How do organisms maintain homeostasis?

The state which maintains the physical, chemical and internal condition inside the body by the living system is called homeostasis. This is the condition at which an organism functioned optimally which includes body temperature and blood sugar.

In other words, homeostasis is the tendency of the body to monitor and maintain its internal states up to a stable level.

Option D states that "A man sweating while he runs". It means that when a man runs, his body itself maintains its temperature and the heat energy generated during the movement of the body is converted into a sweat. Thus the man started sweating while the body temperature increases.

Hence we can conclude that option D is an example of an organism maintaining homeostasis.

To know more about homeostasis follow the link given below.

Should rare earth metals continue to be used in magnets? How come?

Answers

I believe yes because then if some how someone discovers a new metal substance then we can judge wheather or not that substance is magnetic.
No because since they are rare they should find some other metal for this because they're rare so we are going to run out soon because we are using them for magnets.
P.S. if you can think of any thing else to put on go a headand do it because your answer could be yes for some reason
