Answer:
B
Explanation:
it's converts electrical energy to mechanical energy.
We r made of atom so v can’t touch anything hehe I just joking
the earth exerts a gravitational force
Answer:
(a) Kav Ne = Kav Kr = 7.29x10⁻²¹J
(b) v(rms) Ne= 659.6m/s and v(rms) Kr= 323.7m/s
Explanation:
(a) According to the kinetic theory of gases the average kinetic energy of the gases can be calculated by:
(1)
<em>where 
: is the kinetic energy, k: Boltzmann constant = 1.38x10⁻²³J/K, and T: is the temperature </em>
<u>From equation (1), we can calculate the</u><u> average kinetic energies for the krypton and the neon:</u>
(b) The rms speeds of the gases can be calculated by:
<em>where m: is the mass of the gases and 
: is the root mean square speed of the gases</em>
For the neon:
For the krypton:
Have a nice day!
Answer:
if we double the distance the energy stored will be doubled also
Explanation:
The energy stored in a capacitor is given as
Energy stored =1/2(cv²)
Or
= 1/2(Qv)
Where c = capacitance
Q= charge
But the electric field is expressed as
E= v/d
where v= voltage
d= distance
v=Ed
Substituting into any equation above say
Energy stored =1/2(Qv)
Substituting v=Ev
Energy stored =1/2(QEd)
From the equation above it shows that if we double the distance The energy stored will be doubled also
