Ablacksmith is flattening a steel plate that measures 10 cm × 15 cm × 1 mm. he has heated the plate to 900 k. if the emissivity of the plate is 0.75, what is the total rate atwhich it radiates energy

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
