Answer:
9.43 m/s
Explanation:
First of all, we calculate the final kinetic energy of the car.
According to the work-energy theorem, the work done on the car is equal to its change in kinetic energy:
where
W = -36.733 J is the work done on the car (negative because the car is slowing down, so the work is done in the direction opposite to the motion of the car)
is the final kinetic energy
is the initial kinetic energy
Solving,
Now we can find the final speed of the car by using the formula for kinetic energy
where
m = 661 kg is the mass of the car
v is its final speed
Solving for v, we find
Ans: Dilute the solution
Explanation:
To decrease the over-saturation, dilute the solution. Dilution<span> is the process of decreasing the solute's concentration in the </span>solution. It is<span> usually done by mixing with more solvent. In other words, to </span>dilute<span> a </span>solution<span> means to add more solvent without the addition of more solute.</span>
Answer:
True.
Explanation:
When you say something has a velocity, you are measuring its change of position relative to some reference point which may itself be in motion. All motion is relative to a chosen frame of reference.
Answer: i'm not fully sure but i think it's A.
Explanation: why do i think the answer is a? well the parallel circuit definition is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. which means that if you unscrew/remove one bulb it would still work, but in a series circuit it will not work, because if you remove one it turns all the bulbs off.
C. Molecules in the original disturbance disturb (move) adjacent molecules which disturb more adjacent molecules and so the wave travels.
<h3>What is wave?</h3>
A wave can be defined as a propagating dynamic disturbance of one or more quantities.
A wave can be propagated in longitudinal or transverse method.
When waves start as a disturbance (an input of energy) in a medium (water, air, the earth etc).
The energy of the disturbance is moved from the starting point to other places in the medium by molecules in the original disturbance disturb (move) adjacent molecules which disturb more adjacent molecules and so the wave travels.
Thus, the correct option is C.
"Molecules in the original disturbance disturb (move) adjacent molecules which disturb more adjacent molecules and so the wave travels".
