All of them apply because they all are doing some thing to move
Answer:
define 1 second time
One second is the time that elapses during 9,192,631,770 (9.192631770 x 10 9 ) cycles of the radiation produced by the transition between two levels of the cesium 133 atom. ... One second is equal to 1/86,400 of a mean solar day.
A) <u>Weight = mass × acceleration (due to gravity) </u>
= 60×9.8
= 588 N
<u>B) Potential energy = mass x gravity x change in height
</u>
1,000 = 60.0 x 9.8 x h
h = 1.7 m
<u>C) Kinetic energyF = potential energyI
</u>
KEF = 1/2mv2
PEI = mgh = 1,000 J
1/2mv2 = 1,000
1/2(60.0)v2 = 1,000
v2 = 33.33
v = 5.77 m/s
Answer:
Explanation:
mass of liquid m₁ = 161 g
temperature t₁ = 31.8
final temperature t₂ = 28.8
Let m g of ice melted to cool the liquid
heat gained = mass x latent heat of fusion + mass x loss of temp x s heat of water
= m x 80 + m x 1 x ( 31.8 - 28.8 ) ( latent heat of ice = 80 cals/g )
= 83 m
heat lost = 161 x 1 x ( 31.8 - 28.8 ) ( specific heat of water = 1 cal / g / k )
= 161 x 3
heat lost = heat gained
83 m = 161 x 3
m = 5.82 g
mass of remaining ice = 131 - 5.82
= 125.18 g
There is a a thing. so you use the scientific method by
The observation, measuring, and the experiment. also the formulation and then testing of your hypothesis
