Answer:
Yes is large enough
Explanation:
We need to apply the second Newton's Law to find the solution.
We know that,
And we know as well that
Replacing the aceleration value in the equation force we have,
Substituting our values we have,
The weight of the person is then,
<em>We can conclude that force on the ball is large to lift the ball</em>
Answer:
a
The speed of wave is
b
The new speed of the two waves is
Explanation:
From the question we are told that
The mass of the string is
The length is
The tension is
Now the velocity of the first wave is mathematically represented as
Where is the linear density which is mathematically represented as
substituting values
So
Now given that the Tension, mass and length are constant the velocity of the second wave will same as that of first wave (reference PHYS 1100 )
