Answer:
cuz he use parachute
Explanation:
free fall is when you are falling and accelerating with G, so as parachuist using parachute and decelerating it's not free fall.
Answer:
Scientists have identified about a dozen major and several minor tectonic plates
As we know by the first law of thermodynamics
here we know that
Q = heat given to the system
W = work done by the system
now here we can say
now we can say that heat will be given as
now here we can say that Jin does the error in his first step while calculation of change in internal energy as he had to subtract it while he added the two energy
So best describe Jin's Error is
<em>B )For step 1, he should have subtracted 78 J from 180 J to find the change in internal energy. </em>
Answer:
7506 cal
Explanation:
Given: Mass of water = m = 13.9 grams.
Heat energy required to determine the conversion of 13.9 grams of water to steam or vapor is m L,
where L = Latent heat of vaporization of water=540 cal/g.
Q = mL = (13.9)(540) = 7,506 cal.
Answer:
Geologists have known for about 100 years that the Earth is composed of four layers; the Crust, the Mantle, the Outer Core, and the Inner Core . Scientists still argue about the makeup of these layers and exactly how each layer interact with the other layers.
