Answer:
The lid becomes tighter
It becomes tighter because metals have a lower heat capacity than glass meaning their temperature drops (or increases) much faster than glass for the same energy change. So in this example, the metal will contract faster than the glass causing it to be more tighter around the glass.
Whenever the motion of an object <em><u>changes</u></em> . . . speeding up, or slowing down,
or changing direction . . . that change is called "<em><u>acceleration</u></em>". Acceleration is
produced by force on the object.
If there is <em><u>no force</u></em> on the object, then there is no acceleration. That means that
its motion <em><u>doesn't change</u></em>. The object remains in constant, uniform motion ...
moving with steady speed, in a straight line.
No force is necessary to <em><u>keep</u></em> an object moving, only to <em><u>change</u></em> its motion.
Answer:
It is a predator.
Explanation:
They eat other insects so therefore I think they're a predator.
It would be a neutral,
The acidity of water is 7 as well
Answer:
-60.82 m/s²
Explanation:
recall that the acceleration due to gravity, g = 9.81 m/s²
We must also realize that during the car crash, the moving car is being brought to a stop. Hence, it is actually a deceleration (i.e a negative acceleration)
Therefore we must add a negative sign to our acceleration to describe the deceleration.
acceleration = - 6.2g
= -6.2 x 9.81 m/s²
= -60.8 m/s²
