Objects can have the same mass (but different <span>compositions). Only mass or volume cannot tell you if the object is solid or vo</span>lumes) or same volume (but different masses)
Answer:
m₁ (R +ℓ/2) / /( m₁ + m₂ )
Explanation:
We shall consider centre of the club's head as origin .
The centre of mass of the rod attached with sphere will be away from the centre of sphere by a distance
= R + ℓ /2 and its mass is m₁
mass of sphere is m₂ and distance of its centre of mass from origin is zero
So required CM = m₁ x₁ + m₂ x₂ / ( m₁ + m₂ )
= m₁ (R + ℓ /2) + m₂ x 0 /( m₁ + m₂ )
= m₁ (R +ℓ/2) / /( m₁ + m₂ )
Answer:
<h2>c. remain constant</h2>
Explanation:
Such type of field that is created by the magnetic condition is known as magnetic field. Such type of the developed by electrical condition and some other ways. This filed has many important roles in electrical engineering and some other fields.
When any magnetic field acts in perpendicular condition then no work is done by the field. Thus the kinetic energy and speed of the particle remain in constant condition.
