In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. Which statement a

ccurately describes the change in potential energy?
a
The potential energy does not change because the magnets in the system do not change.


b
The potential energy increases because Magnet 1 moves against the magnetic force.


c
The potential energy decreases because Magnet 1 moves against the magnetic force.


d
The potential energy decreases because Magnet 1 moves in the same direction a

The index of refraction of n-propyl alcohol is 1.39. Find the angle of refraction of light in that medium if light comes from ai
iogann1982 [59]

Answer:

36.11 degrees

Explanation:

index of refraction n = sin i/sinr

i is the angle of incidence

r is the angle of refraction

Substitute into the expression

1.39 = sin55/sin(r)

1.39 = 0.8191/sin(r)

sin(r) = 0.8191/1.39

sin(r) = 0.5893

r = arcsin(0.5893)

r = 36.11

hence the angle of refraction of light is 36.11 degrees

A concave mirror can form a real image, which is a copy of an object that forms _____.
viktelen [127]
I hope I can help! :)

A concave mirror is when the object is anywhere from infinity to focus the image so form will be real and inverted.

And when the object is between pole and focus of concave mirror then image so formed will be virtual and erect and the size of image is greater than size of object.

So, the answer would be "where light rays disperse."

Have a great day/evening/night! :)

A football player kicks a ball with an initial velocity of 25 m/s at an angle of 53 degrees above the horizontal. The vertical c
Verdich [7]

Answer:

20 m/s

Explanation:

initial velocity, u= 25m/s

u has two components. one in horizontal and in one vertical.

so,

u sin theta = vertical component.

=> u sin theta = 25× 4/5

= 20 m/s
