Answer:
kJ
Explanation:
= mass of 1 mole of water = 18 g
= given mass of water = 50 g
Number of moles of water in the given amount is given as
= Heat of fusion of water = 6.01 kJ/mol = 6010 J/mol
= specific heat of water = 75.3 J/mol
= Change in temperature = 22.0 °C
Amount of heat required is given as
J

The detailed steps and appropriate derivation is as shown in the attached file.
The force exerted by the laser beam on a completely absorbing target is .
The given parameters;
- <em>power of the laser light, P = 1050 W</em>
- <em>wavelength of the emitted light, λ = 10 μm </em>
The speed of the emitted laser light is given as;
v = 3 x 10⁸ m/s
The force exerted by the laser beam on a completely absorbing target is calculated as follows;
P = Fv
Thus, the force exerted by the laser beam on a completely absorbing target is .
