Answer:
0.0757 kg
Explanation:
m = mass of the body = 95 kg = 95000 g
ΔT = change in the temperature of the body = 0.45 °C
c = specific heat capacity of the body = 4.0 J/(g °C)
M = mass of water evaporated
L = latent heat of vaporization of water = 2260 J/g
Using conservation of heat
Heat gained by water = heat lost by body
ML = m c ΔT
M (2260) = (95000) (4.0) (0.45)
M = 75.7 g
M = 0.0757 kg
We know that a charge moving in a magnetic field is subject to the force:
F = q · v · B
But we also know that:
F = m · a
Therefore, it must be:
m · a = <span>q · v · B
And solving for a:
</span>a = <span>q · v · B / m
Recall that for a proton:
q = 1.6</span>×10⁻¹⁹ C
m = 1.673×10⁻²⁷ kg
Now, you can find:
a = 1.6×10⁻¹⁹ · 7.0 · 1.7 / <span>1.673×10⁻²⁷
= 1.14</span>×10⁹ m/s²
Hence, the acceleration of the proton is 1.14<span>×10⁹ m/s²</span>.
