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
Not ice to hand, but ice to nail to hand. The longer you have the nail on the ice the colder it becomes. Therefore resulting in your hand becoming colder.
- "Gravity is a universal attraction between any two objects with mass. Every object in the universe is affected by the force of gravity. The two factors that affect the magnitude of gravity are the mass of the attracted objects and the distance between them. The greater the masses the greater the gravitational force between two objects."
I think it is chlorine
protons =17
z= 17
neutron=18
