seconds.
The average time to the second quarter checkpoint is
seconds.
The average time to the third quarter checkpoint is
seconds.

seconds.
Answers
Answer:
The average time to the first quarter checkpoint is 2.07 seconds.The average time to the second quarter checkpoint is 3.16 seconds.The average time to the third quarter check point is 4.11 seconds.The average time to the finish line is 4.92 seconds.Explanation: I got it right on edge2021 :)
s
average we find the average times for each checkpoint
point 1 [tex]t_{avg}[/tex] = 2.07 s
point 2 t_{avg} = 3.16 s
point 3 t_{avg} = 4.11 s
point 4 t_{avg} = 4.92 s
given parameters
* Graph with time for each interval
to calculate
* average time for each interval (checkpoint)
The average of a magnitude is
[tex]t_{avg} = \sum \frac{t_i}{n}[/tex]
where [tex]t_{avg}[/tex] in the average time, t_i each time the magnitude is measured and n the number of times the measurement is repeated for the same point.
The table shows the times measured for each interval
measurement time (s) in interval,
1 2 3 4
1 2.02 3.17 4.12 4.93
2 2.05 3.07 3.98 4.81
3 2.15 3.25 4.23 5.01
we look for the average time to get married check point
point 1
t_{avg} = (2.02 + 2.05 + 2.15) / 3
t_{avg} = 2.07 s
Point 2
t_{avg} = (3.17 +3.07 + 3.25) / 3
t_{avg} = 3.16 s
point 3
t_{avg} = (4.12 + 3.98 + 4.23) / 3
t_{avg} = 4.11 s
checkpoint 4
t_{avg} = (4.93 + 4.81 + 5.01) / 3
t_{avg} = 4.917 s
We use the criterion of significant figures for the sum, which is stable that the result must be given with the number of decimal places of the figure that I have the least.
t_{avg} = 4.92 s
the average allows to find the average times for each check point
point 1 tavg = 2.07 s
point 2 tavg = 3.16 s
point 3 tavg = 4.11 s
point 4 tavg = 4.92 s

A 1000 kg boulder sits at the top of a 50-meter high cliff. Determine the amount of potential energy possessed by the boulder if the acceleration due to gravity is 9.8 m/s2. The boulder has_______(magnitude/ number)_______(units) of Potential Energy.
Answers
Answer:
490000J
Explanation:
Given parameters:
Mass of boulder = 1000kg
Height of cliff = 50m
Acceleration due to gravity = 9.8m/s²
Unknown:
Potential energy = ?
Solution:
Potential energy is due to the position of a body. It is expressed as;
P.E = mgH
m is the mass
g is the acceleration due gravity
H is the height
Now insert the parameters and solve;
P.E = 1000 x 9.8 x 50 = 490000J
Data:
m = 1000 kg
h = 50 m
g = 9.8 m/s^2
Find:
P.E = ?
Formula:
P.E = mgh
Solution:
P.E = mgh
P.E = (1000)*(9.8)*(50)
P.E = 490000 J
Result:
P.E = 490000 Joule

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?
Answers
Answer:
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Explanation:
Answer:
For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.
Answers
Answer:
It actually depends.
Explanation:
in the case of a metal ur hand will absorb the heat (but it depends on the temperature, this ans favours hot and cold but not neutral or room temperature), in the case of human to human I think no heat transfer will take place, in the case of liquids(for hot temperature ,it would even for cold but not room).
It basically involves application

What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.
Answers
Answer:
Explanation:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object
which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

C.a 100-pound car moving at 80 miles per hour
D. a 50-pound car moving at 100 miles per hour
Answers
Answer:
B
Explanation:
Momentum is the product or multiplication of a body's mass and its speed.
Since all options have the mass and speed in the same units, there is no need for conversion.
A. 20 x 500 = 10000, B. 200 x 60 = 12000

What is a characteristic of a gas?
Answers
Answer:
Gases have three characteristic properties: 1. they are easy to compress, 2. they expand to fill their containers, and 3.they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.
Explanation:
Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
