Answer: E = 1.62*10^-3 v
Explanation:
Given
L = 1.9 m
V = 19 m/s
B = 4.5*10^-5 T
Induced emf can be found by using the formula for induced emf in a moving conductor.
e = blv, where
B is the component of the earth's magnetic field.
L is the width of the car in m
V is the velocity of the car in m/s
E is the induced emf in volts.
E = 4.5*10^-5 * 1.9 * 19
E = 1.62*10^-3 v
The drivers side is more positive, so the charge would remain positive
Answer:
The force is
Explanation:
From the question we are told that
The tangential resistive force is
The mass of the wheel is m = 1.80 kg
The diameter of the wheel is
The diameter of the sprocket is
The angular acceleration considered is
Generally the radius of the wheel is
=>
=>
Generally the radius of the sprocket is
=>
=>
Generally the moment of inertia of the wheel is mathematically represented as
=>
=>
Generally the torque experienced by the wheel due to the forces acting on it is mathematically represented as
Here is the force acting on the sprocket
So
Generally the torques that will cause the wheel to move with is mathematically represented as
So
Answer:
570 nm
Explanation:
The wavelength of an electromagnetic wave is given by:
where
is the speed of light (the speed of the electromagnetic waves in a vacuum)
is the frequency of the emitted light
Substituting the numbers into the equation, we can find , the wavelength of the emitted light:
Mass is a measure of the amount of matter in a substance or an object.
Answer:
Charles law explains that volume is directly proportional to temperature
Explanation:
- u would equate V1/T1=V2/T2
- U are looking for V2 since u already have V1 , T1 and T2
