Two masses 5kg and 7kg, placed on a frictionless, horizontal surface are connected by a light string. A force of 50N is exerted on the 5kg mass at angle of 20° to the right. Calculate the acceleration of the system​

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus

An object's buoyant force and weight mean the same thing.a. trueb. false

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
