I am not sure if this is what your looking for but most machines use oil
Answer:
G. It will take twice as long.
Explanation:
Let's call 
the original speed of the plane and 
the distance between Dallas and Pensacola. The time the plane originally takes to complete the flight is
In this problem, we are told that the plane encounters wind moving at half of its speed: 
, in the opposite direction. This means that the new speed of the plane is
And so, the time the plane takes now to complete the flight is
So, the plane takes twice the time as before.
Answer:
The current in the circuit must be zero.
Explanation:
In a RC circuit, the steady state is reached when either the capacitor is fully charged or fully discharged. In either case, there must not be any current through the circuit because if it exists, it will deliver charge to the capacitor and thus change its charge, which is not a steady state.
Answer:
B. 1500 kg*m/s
Explanation:
Momentum p = m* v
In any type of collision, the total momentum is preserved!
The total momentum before and the total momentum after the collision is the same. We know the mass and speed after the collision so we can calculate the total momentum.
p1 + p2 =
m1*v1 + m2*v2
m1 = me = 300 kg
v1 = 3 m/s
v2 = 2 m/s
Substitute the given numbers:
300*3 + 300+2
900 + 600
1500 kg*m/s, which is answer B.
