The body systems that help cells get the energy they need are the digestive system and circulatory system. The first system is the digestive system because when you eat food, your body breaks it down using the stomach and other different parts of the digestive system. The next one is the circulatory system because your blood carries the nutrients you acquired from food you digested to the cells throughout your body.
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
Answer:
a) 0.323m/s b) 54.278 m/s
Explanation:
The shell is moving upward with a speed of 17m/s
1.7s after it was launch
Using equation of motion on a straight line,
Vfinal = Vintial + acceleration due to gravity *time
Where V represent the speed(velocity)
Vinital = V(at 1.7s) - 9.81* 1.7
Vinital = 17 - 16.677
a) Vinital = 0.323m/s
b) using the same equation,
V(after 5.5s) = Vinital + 9.81*5.5s
Vafter5.5s = 0.323 + 53.955
V after 5.5s = 54.278m/s
Decreasing pressure on a gas will cause its volume to increase, as it isn't being forced into a smaller space. Increasing temperature causes the atoms in the gas to contain more energy, making them move around more. This too increases the volume.
So basically both would increase the volume of the gas. Hope this helps
Answer:
Northeast
Explanation:
I'm not sure if there's some fancy thing you have to do, but if there's no cardinal compass given, I think it's safe to assume that the answer is based off of one. Therefore, up is north, right is east, so Maple Creek flows to the northeast.
However, if they do give you one where, say, north points downwards, the creek would flow to the southwest. But again, from what is shown, there's no compass, so NE is your best guess here.
