Answer:
F = M a
W = M g equivalent equation to express weight of object of mass M
M = W / g = 2867 N / 9.8 m/s^2 = 292.6 kg
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:
1.48 kg
Explanation:
mass of copper = 4 kg
Decrease in temperature of copper = 36.9°C
increase in temperature of water = 9.20°C
Let the mass of water is m.
Specific heat of water = 4181 J/Kg°C
Specific heat of copper = 385 J/kg°C
According to the principle of caloriemetery
Heat lost by copper = heat gained by water
mass of copper x specific heat of copper x decrease in temperature = mass of water x specific heat of water x increase in temperature
4 x 385 x 36.9 = m x 4181 x 9.20
56826 = 38465.2 m
m = 1.48 kg
Thus, the mas of water is 1.48 kg.

The BIG Equation. Newton's second law<span> of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.</span>
