What happens to the heat energy the particles receive during convection and conduction?

For every action there is an equal and opposite reaction. What does this phrase mean in Physics?

Trava [24]

Answer:

Explanation:

The Term "For every action, there is an equal and opposite reaction" is derived from Newton's third law of motion.

This can be explained by an example of a block placed on the flat surface.

The weight of the block applies an action force on the surface while Surface applies a reaction force on the block. Action and reaction force applies to different bodies other would have canceled each other. Action and reaction forces are always acting in pairs. The magnitude of reaction force depends upon the action forces as both of them are equal in magnitude but opposite in direction.

All BUT one statement applies to electromagnetic radiation. That is

koban [17]

A) Radio waves are a form of electromagnetic radiation.

TRUE

It is the type of electromagnetic wave with least energy range and longest wavelength range among all

B) Electromagnetic radiation does not require a medium to travel.

TRUE

This radiation can travel through vacuum also and its speed is maximum in vacuum

C) In a vacuum, electromagnetic radiation travels at the speed of light.

TRUE

speed of all electromagnetic radiation is same as speed of light in vacuum

D) Electromagnetic radiation travels in the form of longitudinal waves.

FALSE

All electromagnetic radiation is always in form of transverse waves

So correct options are

A, B, C

As shown in the diagram, two forces act on an object. The forces have magnitudes F1 = 5.7 N and F2 = 1.9 N. What third force wil

galina1969 [7]

Answer:

Second option 6.3 N at 162° counterclockwise from

F1->

Explanation:

Observe the attached image. We must calculate the sum of all the forces in the direction x and in the direction y and equal the sum of the forces to 0.

For the address x we have:

$-F_3sin(b) + F_1 = 0$

For the address and we have:

$-F_3cos(b) + F_2 = 0$

The forces $F_1$ and $F_2$ are known

$F_1 = 5.7\ N\\\\F_2 = 1.9\ N$

We have 2 unknowns ( $F_3$ and b) and we have 2 equations.

Now we clear $F_3$ from the second equation and introduce it into the first equation.

$F_3 = \frac{F_2}{cos (b)}$

Then

$-\frac{F_2}{cos (b)}sin(b)+F_1 = 0\\\\F_1 = \frac{F_2}{cos (b)}sin(b)\\\\F_1 = F_2tan(b)\\\\tan(b) = \frac{F_1}{F_2}\\\\tan(b) = \frac{5.7}{1.9}\\\\tan^{-1}(\frac{5.7}{1.9}) = b\\\\b= 72\°\\\\m = b +90\\\\\m= 162\°$

Then we find the value of $F_3$

$F_3 = \frac{F_1}{sin(b)}\\\\F_3 =\frac{5.7}{sin(72\°)}\\\\F_3 = 6.01 N$

Finally the answer is 6.3 N at 162° counterclockwise from

F1->
