Answer:
e. 7V
Explanation:
If the potential created at the point P by the first charge is 5 V, and the electric potential created by the second charge is 2 V, as the potential is proportional to the electric field created by the charges, which is linear (due to it is directly proportional to the value of the charges), we can apply the superposition principle.
In this way, we can calculate the total potential, at a point P, as the algebraic sum of the potentials created by all the charges, as if the other ones were not present.
In this case, we have:
V = V₁ + V₂ = 5 V + 2 V = 7 V
any two uses of good conductor of heat are
aluminium, cooper, metal are good conductor of heat and they are used for making utensils.
gold, silver, are also good conductor of heat they are used for making jewelleries.
To determine the answer to this item, we use two (2) equations.
Equation for kinetic energy:
KE = 0.5 mv²
Equation for momentum:
P = mv
From the second equation, we can deduced that,
m = P/v
Substituting the known values from the given above,
m = 30/v
Using this expression in the first equation,
KE = 0.5 mv²; 150 = 0.5(30/v)(v²)
The value of v from the equation is 10 m/s.
The mass is therefore calculated as such,
m = 30/v = 30/10 = 3 kg
Hence, the answers are,
<em> Mass = 3 kg</em>
<em> Velocity = 10 m/s</em>
Answer:
Gamma rays
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
