Amouse is running along the floor in a straight line at 1.3 m/s. a cat runs after it and, perfectly judging the distance d to the mouse ahead, springs up at a speed of 2.5 m/s and an angle 38 degree, landing right on top of the mouse.
what is d, the distance between the cat and mouse at the instant the cat springs into the air?
c) 0.401 m
i believe it would be could be wrong
recall the equation relating an object's change in thermal energy to its change in temperature:
δq = mcδt
δq is the change in thermal energy.
m is the mass of the object.
c is the object's specific heat.
δt is the object's change in temperature.
m = 0.5 kg = 500g
δt = (7-0)⁰c = 7°c
online sources say the specific heat of silver is 0.240 j/g⁰c
substitute the terms in the equation with the given values and solve for δq:
δq = 500×0.240×7δq = 840 j
the answer to your question is high voltage and high currency
