Water in a tank which is positioned 5 feet above the ground is _____ potential energy? (answers would be like thermal, electric, mechanical)
Answer:
Mechanical
Explanation:
The tank is at rest. And energy of any substance at rest is known as potential energy.
Now, in forms of energy, potential energy is a type of mechanical energy.
Thus, the correct option is mechanical Energy.
the distance and direction between starting and ending positions
Answer:
The length traveled by an object moving in any direction or even changing direction is called distance. The location of an object in a frame of reference is called position. For straight line motion, positions can be shown using a number line. The separation between original and final position is called displacement
Explanation:

in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)
A girl who is watching a plane fly tells her friend that the plane isn't moving at all. Describe a frame of reference in which the girl's description would be true.
The girl's reference frame must be moving with the same speed as the plane.
If an observer is stationary and he watches a car moving he can observe that the car has a momentum and is moving with certain speed. But if the observer is in the car or moving with same speed, the car does not appear to move away form the observer. Likewise, two observers moving with different speed will have different observation about the same car.
Similarly, if the girl describes the plane is not moving that means either she is in the plane or moving with the same speed along with the plane.

A car is traveling at 120 kilometers per hour with 35,000 joules of kinetic energy on the freeway when it suddenly applies its brakes and comes to a screeching stop. How much of the original 35,000 joules of energy is left?
Answer:
0 J is left (No amount of the original 35000 J energy is left)
Explanation:
From the question
Kinetic Energy (K.E) = 1/2mv²................... Equation 1
Where m = mass of the car, v = velocity of the car.
make m the subject of the equation.
m = 2K.E/v²..................... Equation 2
Given: K.E = 35000 Joules, v = 120 km/h = (120×3600/1000) = 432 m/s
Substitute these values into equation 2
m = (2×35000)/432²
m = 0.375 kg.
If a brake is suddenly apply,
Then, the velocity of the car = 0 m/s.
Therefore,
K.E = 1/2(0.375×0²)
K.E = 0 J.
From the baove analysis, No amount of the original 35000 J energy is left.
