Answer:
The density of the sun is 4434kg/m³
This was found by dividing the mass (1.989 ×10³⁰kg) by the volume (4.486×10²⁶ m³) which was calculated using V = 4/3×pi ×r³
Explanation:
See attachment below.
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?
