A Carnot engine takes in heat from a reservoir at 470°C and releases heat to the lower-temperature reservoir at 200°C. What is its efficiency.
To estimate the muzzle speed of a blow dart, fire dart straight up into the air and time how long it takes to come back down. Roughly half of that time is the time for object to decelerate from its initial velocity to motionless. Estimation the in..
What is an acceleration of the car
Discuss briefly centripetal acceleration, the speed and the force exerted by a ball attached to a string.
A gymnast of mass 69.0 kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
A stand, string, a paper or plastic cup, a nail, a roll of paper towels or similar sized paper, coloured sand, or some other dry powdery product, and a ruler or measuring tape.
define the speed of the particle when the string is parallel to the electric field.
