... 5. Two forces are acting on an object. Which of the following statements is correct? (a) The object is in equilibrium if the forces are equal in magnitude and opposite in direction. (b) The object is in equilibrium if the net torque on the object is zero. (c) The object is in equilibrium if the forc ...

... In the figure shown, the coefficient of kinetic friction between the block and the incline is 0.29. What is the magnitude of the acceleration of the suspended block as it falls? Disregard any pulley mass or friction in the pulley. Draw the free body diagrams for each mass. Derive a general solution ...

... SET UP: First use energy conservation to find the speed of the alpha particles as they enter the region between the plates: qV 1/2 mv2. The electric field between the plates due to the battery is E Vbd . For the alpha particles not to be deflected, the magnetic force must cancel the electric for ...

... We have an idea of what mass is from everyday life. In physics: Mass (in Phys 207) is a quantity that specifies how much inertia an object has (i.e. a scalar that relates force to acceleration) (Newton’s Second Law) Mass is an inherent property of an object. Mass and weight are different qua ...
