A bar of soap (mass 0.1 kg) is sliding at 1.5 m/s, before smashing into a motionless bar of soap (mass 0.08 kg). After hitting each other, the soap sticks together and continues to slid. Ignore friction. what is the velocity of bars of soap after sticking together?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
