Answer: 14.52*10^6 m/s
Explanation: In order to explain this problem we have to consider the energy conservation for the electron within the coaxial cylidrical wire.
the change in potential energy for the electron; e*ΔV is equal to energy kinetic gained for the electron so:
e*ΔV=1/2*m*v^2 v^=(2*e*ΔV/m)^1/2= (2*1.6*10^-19*600/9.1*10^-31)^1/2=14.52 *10^6 m/s
Answer:
Mechanical advantage
Explanation:
Machines help us in giving more output than the input incurred so it only increases mechanical advantage, all the other quantities are dependent on the mechanical advantage.
Answer:
n=770,880.
Explanation:
Given that
P= 2200 MW
Power of wind farm = 0.4 or 40%
So the power produce by wind farm = 0.4 x P
P'=0.4 x 2200 MW
P'=880 MW
P'=880,000 KW
We know that
1 year = 365 days
1 day = 24 hr
So
1 year = 365 x 24 hr
1 year = 8760
So the energy produce in one year
E= 8760 x P'
E= 8760 x 880,000 KW
Given that average house hold use 10,000 KW-hr
So lets take total n number of house hold use power
E= n x 10,1000
n=770,880.
Answer:
The frequencies are the same.
Explanation:
This is similar to the photoelectric effect. The frequency of the electromagnetic wave has to match a threshold frequency before it can set electrons into oscillation in a receiving antenna. After the frequency of the electromagnetic waves have matched and exceeded this threshold frequency, all of it's energy is converted to the kinetic energy of the electrons it sets into oscillation. And since their energies are similar, the frequencies too, subsequently, will be the same.
Answer:
It is located at the point where circles intersect on a map.
Explanation:
The name 'EPICENTER' was formed by a seismologist from Ireland can Robert Mallet.
An epicenter of an earthquake can be defined as the exact point in the center where as earthquake originated from.
An epicenter of an earthquake can also be defined as the point that is located directly above the focal point of an earthquake.
In other to be able to accurately determine the exact place where an earthquake happens, seismologist try to find out the distance of the earthquake from at least three seismic recording stations. The distance of the earthquake is obtained from a an equipment used by seismologist called seismograph. After obtaining the values if this distance, circles with the right radius are then drawn around each station. The point where the three circles meet or intersect shows us the earthquake's epicenter.
