Considering borrowers race sex and national origin
Explanation:
Edge
Answer:
Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.
Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
Steaming cup of hot tea - The steam is showing heat being transfered into the air.
Ice melting - Heat moves to the ice from the air. This causes the melting from a solid to liquid.
Hot air balloon - A heater inside the balloon heats the air and so the air moves upward. This causes the balloon to rise because the hot air gets trapped inside. When the pilot want to descend, he releases some of the hot air and cool air takes it place, causing the balloon to lower.
Frozen material thawing - Frozen food thaws more quickly under cold running water that if it is placed in water. The action of the running water transfers heat into the food faster.
Answer:
Magnitude of fourth displacement is approximately 95 metres,
Direction of fourth displacement is straight west.
Answer:
The height of the ball, h = 81.63 m
The velocity of the ball at the highest point is zero
Explanation:
Given data,
The mass of the ball, m = 1 kg
The initial velocity of the ball, u = 40 m/s
Using the conservation of energy, the total mechanical energy of the ball initially at u = 40 m/s
E = P.E + K.E
E = 0 + ½ mv²
= ½ x 1 x 40²
= 800 J
The maximum height the ball reaches with the energy E = 20 J
The K.E of the ball is zero at the maximum height
E = mgh
h = E / mg
= 800 / (1 x 9.8)
= 81.63 m
The height of the ball, h = 81.63 m
The velocity of the ball at the highest point is zero.
