Because a liquid can take the wheight of the hydraulic press while a gas could combust under pressure.
Answer:
Where is the graph??
If a car travels from zero to 4 m/s ins 8 sec
a = 4 / 8 = .5 m/s^2
V (2) = 2 * .5 = 1 m/s after 2 sec
S = V t + 1/2 a t^2
S = 1 * 3.9 + 1/2 * 1/2 *3.9^2 = 3.9 + 3.80 = 7.70 m from 2 to 5.9 sec
Check:
Total distance traveled = 1/2 a t^2 = 5.9^2 / 4 = 8.70 m
Distance traveled in 2 sec = 1/2 * 1/2 * 4 = 1 m
Total distance from 2 to 5.9 = 8.7 - 1 = 7.7 m agreeing with thw above
Answer:
True
Explanation:
Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.
I tried, hope this helps :)
