The period is the time taken by the wave to complete an oscillation. The frequency of the given sound is 500 Hz.
<h2>Period:</h2>
It is the time taken by the wave to complete an oscillation. The frequency is inversely proportional to the time:
Where,
- frequency
- period = 0.002 s
Put the value in the equation,
Therefore, the frequency of the given sound is 500 Hz.

Answer:
Maximum acceleration will be equal to
Explanation:
We have given coefficient of kinetic friction
And coefficient of static friction
Acceleration due to gravity
When truck moves maximum force will be equal to
It is given that half of the weight is supported by its drive wheels
So force required
From newtons law maximum acceleration will be equal to
Answer:
The same as the escape velocity of asteorid A (50m/s)
Explanation:
The escape velocity is described as follows:
where is the universal gravitational constant,
is the mass of the asteroid and
is the radius
and since the scape velocity is 50m/s:
Now, if the astroid B has twice mass and twice the radius, we have that tha mass is:
and the radius is:
inserting these values into the formula for escape velocity:
and we have found that , so the two asteroids have the same escape velocity.
We found that the expression for escape velocity remains the same as for asteroid A, this because both quantities (radius and mass) doubled, so it does not affect the equation.
The answer is
Asteroid B would have an escape velocity the same as the escape velocity of asteroid A
