Answer:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... When the pressure exerted on a substance increases, it can cause the substance to condense.

Answer:
It doesn’t really relate
Explanation:
heavier load the parachute must be moving faster to match the downward force of the greater load
and approx terminal velocity when the parachute is open
velocity for Ping pong ball with parachute = 9m/s
velocity for Soccer ball with parachute = 15m/s
velocity for Golf ball with parachute =24m/s
velocity for Watermelon with parachute = 25m/s
so weight of an object doesn’t really realted how fast it falls with a parachute
2.) <span>Heat is transferred from your body into an ice cube by "Conduction"
3.) </span><span>The loudness of a sound will be determined by the wave’s "Frequency"
4.) </span>The speed of a sound wave <span>"is slower than an electromagnetic wave"

Answer:
When he weight of the car is 8.55 x 
N then power = 314.012 KW
When he weight of the car is 1.10 x 
N then power = 43.76 KW
Explanation:
Given that
Initial velocity 
= 0
Final velocity 
= 24.8 
Time = 7.88 sec
We know that power required to accelerate the car is given by
P = 
Change in kinetic energy Δ K.E = 
Since Initial velocity = 0
⇒ Δ K.E = 
⇒ Power P = 
⇒ Power P = 
-------- (1)
(a). The weight of the car is 8.55 x N = 8550 N
Put all the values in above formula
So power P = 
P = 314.012 KW
(b). The weight of the car is 1.10 x N = 11000 N
Put all the values in equation (1) we get
P = 
P = 43.76 KW
Answer:
The number of cell phone users increases every year.
Explanation:
Cell phone providers want people to buy cell phones because they make money off of it. The other two options might cause people not to want a cell phone, which could potentially harm their business.
