A 5 mole sample of liquid acetone is converted to a gas at 75. 0°C. If 628 J are required to raise the temperature of the liquid to the boiling point, 15. 600 kj are required to evaporate the liquid, and 712 J are required to raise the final temperature to 75. 0°C, what is the total energy required for the conversion?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
