can you please translate to english?
Explanation:
Answer: Cannot determine cause we need to know the change of time to calculate the work.
Explanation:
m = 0.5kg
V = 3m/s - 5m/s = -2m/s
P = W/t = Fv
F = ma
W = Fvt
W = (0.5)(9.8)t = 4.9t
In general, pitch increases more rapidly than frequency for tones below 1000 Hz and less rapidly for tones above 1000 Hz. That is, for frequencies above 1000 Hz a greater change in frequency is needed to produce a corresponding change in pitch.
The volume corresponds to the measure of the space occupied by a body. From the given dimensions we can intuit that we are looking to find the Volume of an Cuboid, that is, an orthogonal rectangular prism, whose faces form straight dihedral angles.
Mathematically the volume of this body is given as

Where,
L = Length
W = Width
H = High


Note: The value given for the height was in centimeters, so it was transformed to meters.
I think the answer is 120 minutes hope this helps
