Answer:
10 mL= 0.01 L
Explanation:
V(water) = 20 mL
V(water + a marble) = 30 mL
V(marble) = V(water + a marble) - V(water) = 30 mL - 20 mL = 10 mL= 0.01 L
Speed is defined as distance over time. So, since it traveled 100m in 25 sec, the speed was 100 / 25 = 4 m/s.
Answer:
A
Explanation:
Momentum conservation will cause 0.08kg to move to the west (opposite of 0.02 kg).
and because both are at the same height above the ground, they will take the same time to reach the ground.
The speed of 0.08kg will be less than 0.02 kg, let v be the speed of 0..02kg, then speed of 0.08kg V is
0.02v - (0.08)V = 0
V = 0.02 v/ 0.08 = v/4
The speed of 0.08 kg = v/4
The speed of 0.08 kg is less than 0.02kg.
So 0.02kg strikes the ground farther from the launch point than does the 0.08 kg
The answer would be threshold voltage. It is the minimum value of voltage needed to produce an action potential. It is also known as gate voltage. It is the minimum value that would make turn a transistor on. Hope this answers the question.
Streamlined means less air resistance. The car will need less force so less fuel in order to overcome air resistance. This will make it more fuel efficient.
