Answer:
✔️Car A and Car B are moving in opposite directions.
✔️Car A is moving faster than Car B.
✔️Car A started ahead of car B.
Explanation:
The position-time graph shows Car A and Car B. The graph reveals that both cars are moving in opposite directions.
Car A shows a positive slope and Car B shows a negative slope.
The graph also shows that Car A started ahead of Car B. It's seen from the graph that Car A started from the origin.
Therefore, we conclude that the correct statements are:
✔️Car A and Car B are moving in opposite directions.
✔️Car A is moving faster than Car B.
✔️Car A started ahead of car B.

Using Newton's 2nd law,find the mass if the force is 18 N and the acceleration is 2 m/s/s.
Answer:
9 kg
Explanation:
According to Newton's second law:
[tex]f = ma[/tex]
[tex]m = \frac{f}{a} [/tex]
Given:
f = 18 N
a = 2 m/s^2
Substitute the given values in the formula.
[tex]m = \frac{18}{2} [/tex]
[tex]m = 9[/tex]

How much time will it take an armadillo traveling 0.1 m/s to go 2010 meters?
Answer:
20100s
Explanation:
1. List the point where the car has the greatest potential energy.
2. List the point where the car has the least potential energy.
3. List the point where the car has the greatest kinetic energy.
4. List the point where the car has the least kinetic energy.
Answer:
1) The point where the car has the greatest potential energy is Point A
2) The point where the car has the least potential energy is Point C
3) The point where the car has the greatest kinetic energy is Point C
4) The point where the car has the greatest kinetic energy is Point A
Explanation:
The potential energy of the car is given by the formula, PE = Mass × Gravity × Height
Therefore, as the height increases, the potential energy of the car increases
The total mechanical energy of the car, which is constant, is given by the following equation
The total mechanical energy = The Potential Energy + The Kinetic Energy
Therefore, at the point where the potential energy is lowest, the kinetic energy is highest.

After this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. The bird repeats the back and forth trips until the runner reaches the finish line. How far does the bird travel from the beginning (including the distance traveled to the first encounter)? Answer in units of km
Answer:
The appropriate answer will be "8.378 km".
Explanation:
The subsequent trip device runner hits B by repeating the bird. Then the time taken by that of the runner around P to hit B would be:
⇒ [tex]P=\frac{1.2556}{7.3}[/tex]
[tex]=0.172 \ hr[/tex]
Although in this time bird has always been perpetually flying.
Distance covered by bird even before runner approach from P to B will indeed be:
= [tex]29.2\times 0.172[/tex]
= [tex]5.0224[/tex]
Apart from the first encounter, the overall distance traveled by bird would be:
= [tex]5.0224+3.3556[/tex]
= [tex]8.378 \ km[/tex]
which element on the periodic table has the largest atomic number?
Answer:
Oganesson
Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope 294Og have been detected.

Explain why the roller coaster’s potential energy is greater at point 1 than at point 4.
Answer:
Answer: 1/17/2020
Potential energy is directly related to the height of an object. Point 1 is higher than point 4, so the potential energy is greater at point 1.

water is used in hot water bag why
Answer:
Explanation:
Water has highest specific heat compared to other liquids , therefore water gives out largest amount of heat for a fixed temperature change , as compared to other liquids i.e. it cools down slowly than any other liquid . Hence used in hot water bags so that bag remains hot for a long time .

Help please!! 20 points
Answer:
I cant hardly read the words for me to answer
Explanation:
As you add heat, what happens to the kinetic energy of atoms?
The atoms in a hot object move faster than atoms in a cold object.
Answer:
The atoms in a hot object move faster than atoms in a cold object. The atoms in a hot object have more kinetic energy than the atoms in a cold object. Adding heat to a substance will make the atoms vibrate more and when heat leaves the substance; the atoms will vibrate less. Potential energy is stored energy.
A rock is thrown downwards from the edge of the Grand Canyon. With
what velocity will it hit the donkey-riding tourist who is 40 m below?
Answer:
Vf = 28 m/s
Explanation:
In order to find the final velocity of the rock, we will use the 3rd equation of motion. The third equation of motion for vertical direction is written as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height dropped = 40 m
Vf = final velocity of the rock = ?
Vi = Initial Velocity of the rock = 0 m/s (since, rock was initially at rest)
Therefore,
(2)(9.8 m/s²)(40 m) = Vf² - (0 m/s)²
Vf = √(784 m²/s²)
Vf = 28 m/s

We would like to make a 600-ohm resistor out of Nichrome wire with a cross-sectional area of 3.0 10-3 square centimeter. If the resistivity of Nichrome is 110 × 10-6 ohm-centimeter, how long should the wire be?
l = AR/ resistivity
A = 3 × 10^-3 square centimeter
R = 600 ohms
resistivity = 110 × 10^-6 ohmh centimeter
substitute the values in the formula and find l
