Which of the following is not an example of acceleration? A.) A bird, flying at a speed of 5 m/s, speeds up to 10 m/s in a constant direction of north

B.) A car travels along a straight section of highway at a constant 100 km/h

C.) A person runs at a constant 3 mi/h while turning from the north to the east

D.) A car travels along a curve while slowing down to 60 km/h from 100 km/h

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
