If you can show the complete solution, and complete diagram that would be great Each formula ( if it is not a general one) should be derived. You should also apply a cross-product formula to solve the first part.
Pull about two 8 cm ( 3” ) of Scotch tape off the roll. Tape the pieces together, adhesive side to non-adhesive side. Predict what will happen when the pieces of tape are simultaneously pulled apart and brought in proximity. Was your prediction correct? Explain your reasoning.
Each of the systems shown is initially at rest. Neglect axle friction and the mass of each pulley. Determine the velocity of block A for each system after it has moved through 24 ft The velocity of block A for system (1) is _____ft/s. The velocity of block A for system (2) is _____ft/s. The velocity of block A for system (3) is _____ft/s.
TRUE OR FALSE. On the answer sheet, shade the circle for Letter A if the statement is correct. Otherwise, shade the circle for Letter E. I. 1. Boat floats because there is a force that is pushing it up. 2. Only the weight of the object determines if the object will sink or float. 3. If I change the shape of the clay, its weight and volume also change. 4. Cutting a wood in half will also make its density half of the original density. 5. The pressure exerted by the fluid at rest on an object is directly proportional to the density of the liquid and depth and is sometimes called as gauge pressure.
