Answer:
E = 7.99 *10^{-13} J
Explanation:
the given reaction is
we know that energy is given as
where
m_1 H^1 is mass of proton = 1.672622 *10^{-27}
m_1 H^2 is mass of deuterium = 3.344494 *10^{-27}
m_2 H^3 is mass of He = 5.008234 *10^{-27}
E = [1.672622 *10^{-27} + 3.344494 *10^{-27} - 5.008234 *10^{-27} ] *(3*10^8)^2
E = 7.99 *10^{-13} J
A metal spoon. Because metal travels the fastest
Answer:
As the number of turns in the coil increases, the strength of the electromagnet increases.
Explanation:
When current flows through a coil the coil behaves as an electromagnet. The strength of electromagnet depend the amount of current, no of turns of coil and the core of coil.
B=μ₀ N I
μ₀ = permeability of the core
N = Number of turns of the coil
I = Current flowing through the coil
Increasing the current and number of coils increase the strength of electromagnet.
V(y) is the same in all cases so time taken for all cannonballs to go up and down is the same.
