Answer:
a) The car’s speed just after leaving the icy portion of the road is the first part
Explanation:
It probably floats since grams per cm are small
Answer:
A
Explanation:
an electric motor is a machine that converts electrical energy to mechanical energy. a generator is a machine that converts mechanical energy to electrical energy
Centripetal Force (Fcp) = ?
His arm length = Radius (R) = 0.75 m
Discus velocity = Linear Velocity (V) = 5 m/s
Discus mass (m) = 2 kg
Centripetal Acceleration (Acp) = V^2/R or W^2 x R
In this case i will use the V^2/R formula, because it uses the discus velocity (V).


Answer: Last option, 66 N.
Answer:
20 N.
Explanation:
The following data were obtained from the question:
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
Force is simply defined as the product of mass and acceleration i.e
Force = mass (m) × acceleration (a)
F = ma
Thus, we can say that the gravitational force on block B will be the product of the mass of block B and acceleration due to gravity i.e
Gravitational force (F) = mass of block B (m) × acceleration due to gravity (g)
F = mg
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
F = mg
F = 2 × 10
F = 20 N
The, the gravitational force exerted on block B is 20 N
