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 )
I think its b because when there is unbalanced forces it accelerates.
Hope this helps you out
We have negative acceleration when an object projected upwards, while positive acceleration is a free fall.
The further the planet is from the sun the smaller the year is
Answer:
in series, R1 + R2 = RT
6 + R2 = 10
R2 = 4
IN SERIES COMBINATION,
CURRENT REMAINS THE SAME.
IT = VT/RT
IT = 20/10
= 2A
I remains the same in series, hence
I1 = 2A
I2 = 2A
V1 = I R1
= 2 x 6
= 12V
V2 = I R2
= 2 X 4
= 8V
P1 = I2R
= 2 X 2 X 6
= 24 W
P2 = I2R
= 2X 2X 4
= 16 W
TOTAL POWER = P1 + P2
= 40W
