I'd say move faster, unless it's asking something else.
Answer:
1.26 s
Explanation:
Draw a free body diagram. There are three forces: weight force mg pulling down, vertical tension component Tᵧ pulling up, and horizontal tension component Tₓ pulling radially.
Sum of forces in the vertical direction:
∑F = ma
Tᵧ − mg = 0
Tᵧ = mg
Sum of forces in the centripetal direction:
∑F = ma
Tₓ = m v² / r
Tension force must be in the same direction as the string, so:
Tₓ / Tᵧ = 75 / 40
40 Tₓ = 75 Tᵧ
40 m v² / r = 75 mg
8 v² / r = 15 g
v = √(15gr / 8)
Plugging in values:
v = √(15 × 10 m/s² × 0.75 m / 8)
v = 3.75 m/s
The circumference of the path is:
C = 2πr
C = 2π (0.75 m)
C = 4.71 m
So the period is:
t = C / v
t = 4.71 m / 3.75 m/s
t = 1.26 s
Round as needed.
Answer:
direction
Explanation:
because particles surround the bell, so when the bell vibrates, it causes particles surrounding it to vibrate back and forth vigorously. as these particles vibrate they collide with the neighbouring particles, passing on the energy.
hope this is what you are asking, if not please report it so that someone else gets to try it.
