Answer:
They are both extremely hot, they both produce a form of light, they both have/use fire(typically)
Explanation:
Refer to the diagram shown below.
Let I = the moment of inertia of the wheel.
α = 0.81 rad/s², the angular acceleration
r = 0.33 m, the radius of the weel
F = 260 N, the applied tangential force
The applied torque is
T = F*r
= (260 N)*(0.33 m)
= 85.8 N-m
By definition,
T = I*α
Therefore,
I = T/α
= (85.8 N-m)/(0.81 rad/s²)
= 105.93 kg-m²
Answer: 105.93 kg-m²
Answer:
d. Direction and magnitude
Explanation:
The two components of a vector are its magnitude and direction.
Magnitude is the quantity of the substance
Direction is the path.
- Other quantities are called scalar quantities.
- Scalar quantities have only magnitude but no direction.
Examples of vector quantities are velocity, displacement, acceleration.
Answer:
The spring constant is 45.94 N/m.
Explanation:
Given that,
Length = 50 cm
Mass = 270 g
Stretching the spring = 24 cm
We need to calculate the spring constant
Using formula of energy
The change in potential energy equal to the change in kinetic energy.

Put the value into the formula



Hence, The spring constant is 45.94 N/m.
