Answer:
the tension of the rope is 34.95 N
Explanation:
Given;
length of the rope, L = 3 m
mass of the rope, m = 0.105 kg
frequency of the wave, f = 40 Hz
wavelength of the wave, λ = 0.79 m
Let the tension of the rope = T
The speed of the wave is given as;
Therefore, the tension of the rope is 34.95 N
Answer:
The velocity at discharge is 100.46 ft/s
Explanation:
Given that,
Pressure = 68 psi
We need to calculate the pressure in pascal
We need to calculate the velocity
Let the velocity is v.
Using Bernoulli equation
Now, We will convert m/s to ft/s
Hence, The velocity at discharge is 100.46 ft/s

Answer:
It will keep moving at the same speed.
Explanation:
In space, there is vacuum which means that there is no air resistance. Since we remain in the state of free fall in the space, the impact of gravity is also negated on the friction. So the friction will be zero.
As per Newton's first law, we will need to apply external force to change the state of motion of a body. In this case when he let go of the lunch box it has a certain speed. This speed will not changes as there is no friction and no acceleration. So the box will keep on moving with the same speed.
