1. A Baltimore passenger train traveled 80 meters in 15 seconds. What was the average speed
of the train?
Show your work ! PLEASEEEE HELPPP !!
Answer:
45
Explanation:
The average speed of the train was 5.33 meter/second.
What is speed?Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.
Given parameters:
Distance travelled by the train is: d = 80 meters.
Time taken by the train: t = 15 seconds.
Hence, the average speed of the train =
total distance travelled/total time taken
= 80 meters/ 15 seconds.
= 5.33 meter/second.

which pair of chromosomes is the s3x chromosomes? Why?
Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

what is the average acceleration of a car if a car rest from 0m/s and reaches a final velocity is 50m/s in 10m/s
Answer:
Assuming that you meant the final velocity of 50 m/s was reached in 10 s, the answer would be 5 m/s^2.
Explanation:
[tex]V_{f} = V_{i} + at[/tex]
So we update that with the values that we have.
[tex]50 = 0 +a(10)[/tex]
then simplify that using algebra to solve for a and we get 5 m/s^2
force of 7 N acts on an object.
The displacement is, say 8 m, in
the direction of the force
(Fig. 11.3). Let us take it that the
force acts on the object through
the displacement. What is the
work done in this case?
Explanation:
Given
Force (F) = 7 N
Displacement (d) = 8 m
work done (W) = ?
We know that
W = F * d
= 7 * 8
= 56 J
The work done in this case is 56 Joule.
PLEASE HELP ASAP! i will really appreciate it
A driver pushes on a car with a force of 8000 N for 15 seconds but is unable to move it. How much work is done
Answer:
the work done is zero.
Explanation:
Given;
applied force, F = 8000 N
time of force application, t = 15 s
Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.
Work done = Force x displacement
Work done = 8000 N x 0
Work done = 0
Therefore, the work done is zero.

A 0.20 kg baseball is traveling at 40 m/s toward the batter. The ball is hit by the bat with a force of 200N, and is
now headed toward the pitcher at 25 m/s. How long was the bat in contact with the ball?
Answer:
Time, t = 0.015 seconds.
Explanation:
Given the following data;
Mass, m = 0.2kg
Force, F = 200N
Initial velocity, u = 40m/s
Final velocity, v = 25m/s
To find the time;
Ft = m(v - u)
Time, t = m(v - u)/f
Substituting into the equation, we have;
Time, t = 0.2(25 - 40)/200
Time, t = 0.2(-15)/200
Time, t = 3/200
Time, t = 0.015 seconds.
Note: We ignored the negative sign because time can't be negative.
What are the first two of Newton's Laws of Motion?
Answer:

13. Harry used the energy stored in his muscles to cycle up a hill. What happened to this energy when he reached the top?
A. The energy stored in Harry's musclesbwas destroyed.
B. The energy was returned to Harry's muscles
C. Kinetic energy changed to potential energy.
D. Potential energy changed to kinetic energy.
Answer:
C. Kinetic energy changed to potential energy.
Explanation:
The kinetic energy is converted to potential energy when he reaches the top of the hill.
As with every system, energy is neither created nor destroyed but transformed from one form to another.
This is from the law of conservation of energy.
Kinetic energy is produced when Harry moves the up the hill. As he reaches the top of the hill and comes to rest, potential energy is formed.
Potential energy is the energy due to the position of a body.

Ill mark the brainliest pls lmk what answer ty
2800 m
Further explanationGiven
time = 80 s
average velocity = 35 m/s
Required
total distance before it broke down
Solution
Average velocity : total displacement : total time
Can be formulated
avg velocity = Δx : Δt
Input the value :
Δx=avg velocity x Δt
Δx = 35 m/s x 80 s
Δx = 2800 m
In addition, if we are asking for velocity, we must know the starting and ending points (displacement)
But if we calculate the total distance, what is written is the average speed
avg speed = total distance : total time

•Most of the components that make up curcuits are conductors. Electricity flows easily thought conductors such as metal or water.Electricity does not flow easily thought insulators such as wood or rubber.
•When a battery is used to power a circuit, the circuit the current must travel from one pole of the battery to the opposite battery.
•Resisotors show the flow of Electricity throught a circuit this can prevent components of the circuit from 'brning out'. In a curcuit diagram, resistors are represented by bending lines.

a dvd player that is not playing but still plugged in still uses 10.0 of power. what is this vampire current if the machine is plugged into a 120 v electric outlet
Answer:
Current = 0.0833 Amperes
Explanation:
Given the following data;
Power = 10Watts
Voltage = 120V
To find the ampere-current;
Power = current * voltage
Substituting into the equation, we have;
10 = current * 120
Current = 10/120
Current = 0.0833 Amperes
