Given :
A bicycle racer rides from a starting marker to a turnaround marker at 10 m/s.
She then rides back along the same route from the turnaround marker to the starting marker at 25 m/s.
To Find :
Her average speed for the whole race.
Solution :
We know, average velocity is given by :

Therefore, average speed for the whole race is given by 17.5 m/s.
False because they all travel at the same rate
Answer:
The value of variable capacitor is
F
Explanation:
Given :
Inductance
H
Frequency
Hz
According to the cutoff frequency,

Now we find the value of capacitance,


F
Therefore, the value of variable capacitor is
F
The reading on the scale is equal to the weight of the student which is 646.8 N.
The given parameters;
- <em>mass of the student, m = 66 kg</em>
The reading on the scale is determined by applying Newton's second law of motion as follows;

<em>The student is at rest and not accelerating, a =0</em>

Thus, the reading on the scale is equal to the weight of the student which is 646.8 N.
The complete question is below:
A 66 kg student stands on a very light, rigid board that rests on a bathroom scale at each end as shown in (Figure 1). what is the reading on the scale?
