Explanation Given info: The operating voltage of x-ray tube is 4.00 MV and the current of beam is 25.0 mA . Write the expression for the power delivered by the beam. P = I Δ V Here, P is the power. I is the current. Δ V is the operating voltage. Substitute 4.00 MV for Δ V and 25.0 mA for I in above equation. P = ( 25.0 mA ( 10 − 3 A 1 mA ) ) ( 4.00 MV ( 10 6 V 1 MV ) ) = ( 25 × 10 − 3 A ) ( 4.00 × 10 6 V ) = 100 × 10 3 W =1 .0 × 10 5 W Write the expression for consumed energy. Q = P t (1) Here, Q is the energy or heat. t is the time. Write the expression for the required heat to raise the temperature of water. Q = m c Δ T (2) Here, c is the specific heat of the water

1. A 50-N crate sits on a horizontal floor where the coefficient of static friction between the crate and the floor is 0.50. A 20-N force is applied to the crate acting to the right. What is the resulting static friction force acting on the crate? (a) 20 N to the right. (b) 20 N to the left. (c) 25 N to the right. (d) 25 N to the left. (e) None of the above; the crate starts to move.

3. The problem that shall not be named. m A (a) A block of mass m = 1 kg, sits on an incline that has an angle 0. Find the coefficient of static friction by analyzing the system at imminent motion. (hint: static friction will equal the maximum value) (b) A block of mass m = 1kg made of a different material, slides down an incline that has an angle 0 = 45 degrees.
