Answer:
I =1.8 kgm^2
Explanation:
In order to calculate the moment of inertia of the door you use the following formula, which relates the torque applied to the door with its moment of inertia and angular acceleration:
(1)
τ: torque applied to the door
I: moment of inertia of the door
α: angular acceleration = 5 rad/s^2
The torque is also given by τ = Fd, where F is the force applied at a distance of d to the pivot of the door (hinge axis).
F = 10 N
d = 0.9 m
You replace the expression for τ, and solve for I:
The moment of inertia of the door is 1.8 kgm^2
Answer:
2 x 10⁻¹²F
Explanation:
Capacitance is defined as the ration of charge (q) on either plates to the potential difference V between them.
C =
Where q is the charge on the plates
V is the potential difference
From the given parameters:
Charge on plate, q = 2.0 x 10⁻¹⁰C
Potential difference across the plate = 100V
Unknown parameter:
Capacitance of the system = ? = C
Solution
Capacitance = 2.0 x 10⁻¹⁰/100 = 2 x 10⁻¹²F
Answer:
The acceleration of the car is 1.02 m/s².
Explanation:
Given that,
mass = 10 g
Angle = 6°
Suppose we need to find the acceleration of the car.
We need to calculate the tension
Using balance vertical force
Put the value into the formula
We need to calculate the acceleration of the car
Using balance equation
Put the value into the formula
Hence, The acceleration of the car is 1.02 m/s².
