I think the answer should be that, Kinetic energy is contained in a moving object, while potential energy exists in a stored form.
Yeah we need a video to know what you’re talking about
Answer:
6.82%
Explanation:
If 44 ±3 beats are counted in 30 seconds, twice the number of beats will be counted in 1 minute or 60 seconds, i.e. 88 beats per minute. The absolute uncertainty in 1 minute will also be twice the uncertainty in 30 seconds, so 88 ±6 beats per minute.
The percentage uncertainty can be found by below:
The percentage uncertainty can also be found for the 30 second interval
While the absolute uncertainty varies depending on the time interval, the percentage uncertainty remains the same: 6.82%
Answer:
16.5 m
Explanation:
The following data were obtained from the question:
Time (t) = 0.1 s
Speed of sound in air (v) = 330 m/s
Distance (X) =?
The Lenght (i.e distance) of the room can be obtained as follow:
v = 2X / t
330 = 2 × X / 0.1
Cross multiply
2 × X = 330 × 0.1
2 × X = 33
Divide both side by 2
X = 33/2
X = 16.5 m
Thus, the length of the room is 16.5 m.
Answer:
The work done on the gas is 37 J.
Explanation:
let P be the pressure in the chamber.
let V1 be the initial volume of the chamber.
let V2 be the final volume of the chamber.
then, the work done on the gas is given by:
W = P(V2 - V1)
= (1×10^5)(1 - 0.633)×10^-3
= 37 J
Therefore, the work done on the gas is 37 J.
