Answer:
a) Volume = 2/3 
r³
Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³
b) Total surface area = 3r²
Area = 3 × 22/7 × 14 × 14 = 1848 cm²
Explanation :
In Newton's prism experiment, a ray of white sunlight is passed to the prism. It is observed that the light gets refracted at different angles and different colors spread.
Sunlight is made up of seven colors. The colors are the same as the colors seen in the rainbow. The colors are :

The answer is A , the forces are balanced
Answer:
80 N
Explanation:
From the question,
F = ma .......................... Equation 1
Where F = Force, m = mass of the object, a = acceleration of the object.
make m the subject of the equation
m = F/a.................... Equation 2
Given: F = 24 N, a = 3 m/s²
Substitute into equation 2
m = 24/3
m = 8 kg.
If the acceleration of the object becomes 10 m/s²,
Substitute into equation 1
F = 10(8)
F = 80 N.
