The answer is A vaporization
Answer:
False
Explanation:
The time rate of flow of electric current is not the charge. Electric current is the time rate of flow of electric charge.
Its unit is in Amperes;
Electric current =
Therefore, it wrong to say charge is the quantity of electric current that flows per unit of time.
Charge is the amount of electrons within an atom
<span>So we want to know what the proces in which heavy materials sink toward the planets center and lighter materials accumulate near the planets surface is called. The process described here is called differentiation. So the correct answer is C. Differentiation</span>
Answer:
False
Explanation:
False
If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.
By driving zig-zag motion friction force on the tires may stop the car after some distance.
Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.
Short answer, 10kg, it must be the same mass as Ball 1
Long calculation to prove the answer:
M1 = Mass of Ball 1
M2 = Mass of Ball 2
U1 = Initial speed of Ball 1
U2 = Initial speed of Ball 2
V1 = Final speed of Ball 1
V2 = Final speed of Ball 2
M1U1 + M2U2 = M1V1 + M2V2
10 x 20 + M2 x 20 = 10 x 40 + M2 x 0
200 + 20M2 = 400
20M2 = 200
M2 = 200 / 20
M2 = <u>10 kg</u>
Alternatively you could say that because the velocity of ball 1 increased by the exact velocity of ball 2, their masses must be equal, so both ball 1 and 2 are 10 kg.
