Answer:
The Tension
The horizontal component =
The vertical component =
The angular acceleration ∝ =
Explanation:
The illustration of what the question depicts is shown in the diagram below;
SO; Equilibrium
although the net torque is zero about any point ;
Now;
The horizontal component is :
The vertical component is :
F⊥ = mg - T sin θ
=
b) Torque about point 0 =
I is just the uncertainty over the actual number multiplied by 100.
example:
36.1( +/- 0.1)
The percentage of the uncertainty here is 0.1/36.1x 100=0.3%
Answer:
distance traveled by 3 second ball ≈ 45m
distance traveled by 1 second ball ≈ 5m
Explanation:
Since the 2 balls started at rest, their v initial = 0, and since no other force is acting on them except for the gravitational force, they accelerate downwards at 10m/s2.
To calculate the distance traveled by both balls, we apply the second formula of UARM motion:
• Δx = 1/2(a)(t^2) + (v0)(t)
Applying both 1s and 3s in this formula will yield you 5m and 45m respectively.
Hope this helps, brainliest would be appreciated :)
Mercury has less mass than earth. So the answer is B
