Given required solution
M=10kg W=? W=Fd
v=5.0m/s F=mg
t=2.40s =10*10=100N
S=VT
=5m/s*2.4s
=12m
so W=12*100
W=1200J
If u mean pressure, pressure = Force/Area
Correct me if I am wrong :D
Answer:
(a) gravitational potential energy converted to kinetic energy
(b) chemical energy is converted to light or heat energy
(c) mechanical energy is converted into kinetic energy
Answer:
the answer is 32.0-25.0=7
Explanation:
the absolute pressure at the bottom of the container is 7
From the theory we know that:
c = λ / T
f = 1 / T
Where:
c = 3.
/ m (the speed of light)
λ is the wavelengh (in meters)
T is the period (in seconds)
f is the frequency (in Hz)
We were told that:
f = 7.30 .
And we want to find out the value of λ.
c = λ / T
c = λ . 1/T
Swaping 1/T = f
c = λ . f
λ = c / f
λ = 3 .
/ 7.30 . 
λ = 4.12
m
Response: 4.12
m = 412 nm
