Answer:
i don't know if this is right but here,9900 kgm/s
Explanation:
calculator UwU
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
A displacement time graph is able to show if an object is going backwards or forwards for example usually a line with a negative gradient means going backwards (or back to the start) This CAN’T be shown on a distance time graph
A distance time graph shows how far an object has traveled in a given time
So for example...
Distance is plotted on the Y-axis
Time is plotted on the X-axis
So not they are not the same, hope this helped :)
Answer:
Well I'll say the answer is
A.21
B.21
Explanation:
The law of conservation of momentum states that the total momentum in a system remains constant
And
To find the Total momentum in a body, you'll have to multiply the mass of the body to it's velocity
And
To find the total momentum, you'll add the momenta in every body present in the system
A = 4\pi r^2
A = 4\pi (2\mu m /2)^2 (10^{-6}m/1\mu m)^2 (1mm/10{-3})^2
A = 1.33*!0^{-5}MM^2
