Answer:
B
Explanation:
Because of the voltage attached to the iron nail
know how to ride a bike simply put also wear safety gear like a helmet knee pads things like that
hope this helps
Explanation:
(a) Given that,
Area of a parallel plate capacitor, 
The separation between the plates of a capacitor, 
The dielectric constant of, k = 2.1
When a dielectric constant is inserted between parallel plate capacitor, the capacitance is given by :

Putting all the values we get :

(b) We know that the Teflon has dielectric strength of 60 MV/m, 
The voltage difference between the plates at this critical voltage is given by :

or
V = 0.6 kV
Answer:
4.8 m
Explanation:
When it hits the ground, all the kinetic energy is converted to potential energy. Potential energy, PE is given by mgh where m is the mass of the box, g is acceleration due to gravity and h is the height which is unknown for this case
PE=mgh and making h the subject of the formula then
and substituting g with 9.81, PE with 1500 J and m with 32 kg then
