Answer:
how ever many layers it has i think
Explanation:
Answer:
The length of the stick is 0.28 m.
The time the stick take to move is 0.97 ns.
Explanation:
Given that,
Relative speed of stick v= 0.96 c
Speed of light 
Proper length of stick = 1 m
We need to calculate the length of the stick
Using formula of length

Put the value into the formula



We need to calculate the time the stick take to move
Using formula of time

Put the value into the formula



Hence, The length of the stick is 0.28 m.
The time the stick take to move is 0.97 ns.
None of the choices in the picture is correct.
The blue wave has a higher pitch than the orange one, (because its waves are shorter so there are more of them in the same length of time).
AND the blue wave is also louder than the orange one, (because the amplitude of its waves is slightly greater).
Answer:
Explanation:
The work (W) done on the cube to be pushed across the floor is equal to the total thermal energy (ΔE) of the system:
(1)
Also, the work done on the cube by the horizontal force is giving by:
(2)
<em>where F: force applied to the cube , d: displacement of the cube </em>
<em>By equaling the equations (1) and (2)</em>, we can find the thermal energy of the floor:


So, the increase in the thermal energy of the floor is 51 J.
Have a nice day!
