Answer:
a. 11.5kv/m
b.102nC/m^2
c.3.363pF
d. 77.3pC
Explanation:
Data given
to calculate the electric field, we use the equation below
V=Ed
where v=voltage, d= distance and E=electric field.
Hence we have
b.the expression for the charge density is expressed as
σ=ξE
where ξ is the permitivity of air with a value of 8.85*10^-12C^2/N.m^2
If we insert the values we have
c.
from the expression for the capacitance
if we substitute values we arrive at
d. To calculate the charge on each plate, we use the formula below
Answer:
(X - 25)/Y
Explanation:
Change in velocity = X - 25
Time elapsed = Y
Acceleration = Change in velocity/Time = (X - 25)/Y
Answer:
l = l0 ( 1 - u^2/v^2) ^0.5
Explanation:
This is the equation of lenght contraction of special relativity
A mold fossil is a 3D example of an object, while a mold fills up with a sediment like mud. The mold fossil is related to the cast fossil because both can hold an organism or part of an organism.
