[ans: 0.25 kg] 2. A proton moves with a speed of 0 .800c through a particle accelerator In the accelerator's frame of reference,calculate (a) the total and (b) the kinetic energies of the proton in megaelectron-volts TA A [ans: (a) 1.57times 10^3 MeV; (b) 6.26times 10^2MeV]Filinthe Blank 2points The difference between gravitational potential energy and elastic potential energy is that GPE Is due to square while elastic potential energy is due v to square vbar is pivoted on the left end and a force is applied downwards on the right end. The rotation of the bar will be: (a) clockwise (b) counter-clockwise (c) neutral (d) upwardWhen work is done energy is transferred from one object to another. Where is the energy being transferred to from this candle? Chemical energy and nuclear energy Thermal energy and light energy Light energy and electrical energyQuestion 7: (1 point) A 15 m long bar is pivoted on the right end and a force of 5 N is applied downwards on the left end. The moment of force is: (a) 3 Nm counter -clockwise (b) 3 Nm clockwise (c) 75 Nm counter -clockwise (d) 75 Nm clockwisePREV 727374757677787980 NEXT
