Explanation:
The given data is as follows.
Distance (s) = 20 m
time (t) = 0.775 s
Also, it is given that mass per 1 meter length (m) = 0.300 kg
Formula to calculate the velocity is as follows.
Velocity (v) = 
Putting the given values into the above formula as follows.
v =
= 
= 25.80 m/s
We know that,
v = 
Taking square on both the sides, the formula will become as follows.
T = 
= 
= 199.692 N
Therefore, we can conclude that tension in the given tightrope is equal to 199.692 N
.
We are given with
<span>m1 = 9.3 kg
R = 0.22 m
ω = 31 rad/s
m2 = 3.9 kg
L = 2R = 0.44 m
The angular momentum is determined using the formula
L = I w
where I is the moment of inertia
For a solid disk
I = (1/4) MR^2
For a rectangular rod
I = (1/12) ML^2
The rotational energy has the formula
E = (1/2) I w^2
Substitute the given values for getting the answers

Answer:
θ = 4.092 °
Explanation:
Given that
Initial Angular speed ,ωi = 0.76 rad/s
Final angular speed ,ωf= 2.96 rad/s
The angular acceleration ,α = 1 rad/s²
We know that
ωf² = ωi ²+ 2 α θ
θ=Angle rotates
2.96² = 0.76²+ 2 x 1 x θ
Therefore the angle rotates by machine part will be 4.092 degrees.
θ = 4.092 °
Answer:
i wanna say tranverse if not surface
Explanation:
Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles. ... The positive and negative charges cancel producing a neutral atom. images.tutorvista.com. Later discoveries by Rutherford and others lead to additional revisions to atomic theory.
