Answer:
if your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts
Answer:
Kinetic energy = 0.25 J
Explanation:
The question is "If we take container one as a reference and apply 5 grams of ink and the water moves at a speed of 10m / s, what would the kinetic energy of the solution be?"
We have,
Mass of ink, m = 5 grams = 0.005 kg
Speed of water, v = 10 m/s
We need to find the kinetic energy of the solution of water and ink. Kinetic energy is associated with the motion of an object. Its formula is given by :
So, the kinetic energy of the solution is 0.25 Joules.
The relevant equation to use here is:
y = v0 t + 0.5 g t^2
where y is the vertical distance, v0 is initial velocity =
0, t is time, g = 9.8 m/s^2
y = 0 + 0.5 * 9.8 * 3^2
<span>y = 44.1 meters</span>
Answer:
Yes.
Explanation:
Since, the front end of the car exactly even with the front of your car, this means the relative velocity between the two cars is zero. This surely, means that both cars have same velocity such that both person in different cars are in rest with respect to each other. Had their velocities been different, there must had been a relative velocity between them causing them to pass each other.
Answer:
<h2>a) secondary oil recovery.</h2>
Explanation:
Secondary oil recovery is used when the pressure inside the well is to high, being not possible to do a primary oil recovery.
To do this method, high pressure is needed, like this case because it says that ''squirts strongly''.
On the other hand, tertiary oil recovery is used when another method is not possible. Hydraulic fracturing or fracking, it's develop with a horizontal drilling, which is not the case.
