It seems you didnt give the last answer, but a - d seem like pretty reasonable things to do so it is probably C.
It is a passive electronic that stores energy
Answer:
net outward force on a passenger's eardrum is 0.6115 N
Explanation:
Change in pressure is calculated as follows
h= height of liquid column =480 m
ρ= density of liquid= 1.3 kg/m^3
putting values we get
ΔP= 6115 Pa
Area of the eardrum is approximately
= 1 cm^2
Therefore, net force F = AΔP
=
= 0.6115 N
Answer:
- As an ice cube melts, its shape changes as it acquires the ability to flow. ... A physical change is a change to a sample of matter in which some ... The salt may be regained by boiling off the water, leaving the salt ... The resulting mixture is a solution with a pale green color. ... Answer b: chemical change.
Explanation:
First you must convert the weight to mass. So:
W = mg (assuming that gravity is 9.8 Nkg-1)
m = W/g
= 72 / 9.8
= 7.3kg
Then we can use Ep = mgh
= 7.3*9.8*1.4
= 100.1N
