Answer:
B im pretty sure
Explanation:
Answer: The answer is A.
Explanation:
Suppose you are in an elevator. As the elevator starts upward, its speed will increase. During this time when the elevator is moving upward with increasing speed, your weight will be greater than your normal weight at rest.
3.2 m
0.80 m
4.0 m
Answer:
Explanation:
It is known that the oscillation period of a pendulum can be described as
,
where T is the oscillation period, L is the length of the pendulum and, g is the gravity.
Solving For the length we get:
.
We know that g equals 5 times earth's gravity,
,
and from the angular displacement graphics, it can be seen that the period is
.
Now, we can easily compute the length of the pendulum:
Explanation:
The period (time per cycle) is 1.0 s. The gravity is 5g or 49 m/s². Therefore:
T = 2π √(L / g)
1.0 s = 2π √(L / 49 m/s²)
L = 1.2 m
cooled air
I also think it's hot air, but I'm pretty sure it's because hot air rises. I'm not 100% sure so I'm sorry if it wrong :)
Please and Thank you
