Answer:
no
Explanation:
the metal spoon would be higher temperature
All black surfaces is the correct answer
A microscope is an instrument from which you can see the cells of an object.
It helps you to observe the cells of substance.
Powerful microscopes helps better in observing minute particles or bacterias.
Hope it helps...
Kinetic energy. thermal energy (a low form of energy ) is a form of kinetic energy as it is produced as a result of motion of particles either if they vibrate at their position or they move along longer paths. Motion produces friction or resistance which leads to excitation and thus the heat is produced. The higher the motion of the particles, the higher would be the thermal energy.
Applying conservation of momentum
Quarterback mass = 80 kg
ball mass = 0.43 kg
Initially both together but horizontal velocity of both 0
initial momentum = 0
Final momentum = 15*0.43 - 80v
initial = final (law of conservation of momentum)
6.45 = 80v
v = 0.08 m/s
