Aconstant force of magnitude f acts on an object of mass 0.04kg initially at rest at a point o. if the speed of the object when it has moved 50m from o is 500m/s. what is the value of f?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

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.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
