For this case we have that by definition, physical power refers to the amount of work done for a unit of time.
So:

Where:
W: It's the work
t: It's time
The power units are in 
So, according to the problem data we have:

Clearing the work of the formula:

Thus, the work is 1200 joules.
Answer:
Option C
Answer:
24.30 m
Explanation:
v(final)=v(initial)+at
0 m/s= 9 m/s +a(3.2s)
a=-2.81 m/s^2
delta x= vt+ (1/2)at^2
=(9 m/s * 3.2 s)+ (.5* -2.81 m/s^2 * 3.2s)
=24.30 m

it contains every color that humans can see. There are distinct properties of visible light that set it apart from other types of electromagnetic radiation.
Answer and explanation:
A.
Muon travelled straight down towards the earth. Therefore the tree moves up in the rest frame of muon (option a)
B.
In muon rest frame it travels Zero meters
C.
Distance, d = Velocity, v * Time, s


D.
Distance from the top of the mountain to the tree is the same as the distance travelled by the tree in the muons rest frame
that is same as in part C which is 594m
E.
Using lorentz contraction
In the rest frame of someone standing on the mountain
the distance is given by




d' = 258.92m
F.
in the rest frame of someone standing on the mountain,
muon moves straight down
