Insulators does not allow flow of electric charges at all.
bad conductors are those which can conduct electricity but offers more opposition (resistence) to the flow of current compared to the flow of current in a good conductor.
all dielectrics are insulators, but all insulators are not dielectric.
hope this help
Answer:
The Energy possessed by a body by virtue of its position or state is called Potential energy.
Mathematically potential energy can be written as,
Potential energy = mgh
Where 'm' represents mass of the body, 'g' represents gravity of the earth and 'h' represents height of body. Potential energy depends on the height, higher the hight from the surface of the earth, maximum will be the potential energy.
Answer:
distance = 27.95 [mi]
Explanation:
in order to solve this problem, we must use the appropriate conversion factor, i.e. a conversion factor that relates the kilometers to Miles.
![1 [km] = 0.6214 [mill]\\45[km]*0.6212[\frac{mill}{1km} ]=27.95 [mill]](https://tex.z-dn.net/?f=1%20%5Bkm%5D%20%3D%200.6214%20%5Bmill%5D%5C%5C45%5Bkm%5D%2A0.6212%5B%5Cfrac%7Bmill%7D%7B1km%7D%20%5D%3D27.95%20%5Bmill%5D)
The new frequency of oscillation when the car bounces on its springs is 0.447 Hz
<h3>Frequency of oscillation of spring</h3>
The frequency of oscillation of the spring is given by f = (1/2π)√(k/m) where
- k = spring constant and
- m = mass on spring
Now since k is constant, and f ∝ 1/√m.
So, we have f₂/f₁ = √(m₁/m₂) where
- f₁ = initial frequency of spring = 1.0 Hz,
- m₁ = mass of driver,
- f₂ = final frequency of spring and
- m₂ = mass on spring when driver is joined by 4 friends = 5m₁
So, making f₂ subject of the formula, we have
f₂ = [√(m₁/m₂)]f₁
Substituting the values of the variables into the equation, we have
f₂ = [√(m₁/m₂)]f₁
f₂ = [√(m₁/5m₁)]1.0 Hz
f₂ = [√(1/5)]1.0 Hz
f₂ = 1.0 Hz/√5
f₂ = 1.0 Hz/2.236
f₂ = 0.447 Hz
So, the new frequency of oscillation when the car bounces on its springs is 0.447 Hz
