Answer:
The answer is A.) Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Your weight would change if you went to the moon because the gravitational pull is different but your mass would stay the same because the amount of matter in you wouldnt change.
A. Because there is still electricity going through the appliance even though it's turned off
To find or discover by investigation?
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
Answer:
8.5 kg
Explanation:
Angular momentum is conserved.
I₁ ω₁ = I₂ ω₂
I ω₀ = (I + mr²) ω
(49 kg m²) (40 rpm) = (49 kg m² + m (1.2 m)²) (32 rpm)
61.25 kg m² = 49 kg m² + (1.44 m²) m
m = 8.5 kg
The mass of the clay is 8.5 kg.
