Answer:
(a) Force and Pressure
Explanation:
Acc to the formula,
Force = Pressure/Area
Therefore it depends on force and pressure
The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path
Hope this helps.
Answer:
Yes.
Explanation:
When you move your hand from the cold water to the “warmer” (room temp) water, one hand feels warm.
As you move your hand from the warm water to the “colder” (room temp) water, that hand feels colder.
Although both hands experience the last bowl of water at the same temperature, your brain senses two
separate sensations. So the water feels “warm” or “cold” relative to the water your hand was in previously.
The greater the difference in temperature, the easier it is to sense a difference.
The tension in the rod when the ratio of speed is 8 is 1.34 × 10⁴ N.
The longitudinal waves speed is determined using the density of the material and the Youngs modulus with the expression:
v = √(Y/rho)
A wave in a stretched string can be used to represent the transverse wave.
The length of the metal rod is 150 cm and the radius of the rod is cm.
The mass of the rod is 50.9 g.
Now, the Youngs modulus for the material is 6.80× 10¹⁰ N/m².
For the longitudinal wave
v(l) = (Y/ρ)^{1/2}
For the transverse wave :
v(T) = (Y/μ)^{3/2}
Now, we need
v(L) / v(T) = 8
And we know,
T = (μY) / (64ρ) where μ= m /L
And the density, ρ = mass / volume = (m) / (πr²L)
Therefore,
T = (πr²Y) / 64
T = (π)(2 × 10⁻³)² × (6.8 × 10¹⁰) / 64
T = 1.34 × 10⁴ N
