A locomotive is pulling 19 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at on a level track, what is the tension in the coupling between the second and third cars? (The car nearest the locomotive is counted as the first car, and friction is negligible.)
Explanation:
The tension between cars 2 and 3 accelerates cars 3 through 17. That is a total of 15 cars.F = M*a, with M = 15*37,000 = 555*10^3 kga = 0.7 m/s^2Solve for F, in Newtons

Do you think that Franklin actually performed the kite experiment? Why or why not?
Answer:
He not only hypothesized that lightning and electricity were linked, but that metal objects could be used to draw lightning in order to protect homes from being hit. But Franklin didn't feel that he could get his conductor high enough into the clouds to do any good, so he never completed the experiment.

Electromagnets are an example of how electricity can create magnetism is True statement.
What is Electromagnet?Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.
The coils stop functioning as a magnet when the electricity is turned off. When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.
They both make use of electromagnets, which use electricity to apply a magnetic field. Extremely strong electromagnets are used by wrecking yards to transfer heavy scrap metal or even entire cars from one location to another.
Therefore, Electromagnets are an example of how electricity can create magnetism is True statement.

what is resistance
Answer:
Resistance is the measure of the opposition to current flow in an electrical circuit
Resistance refers to the opposition or hindrance that a material or object offers to the flow of electric current. It is a fundamental concept in the field of electrical engineering and physics.
Resistance is measured in ohms (Ω) and is denoted by the symbol "R."
In electrical circuits, resistance is caused by various factors, including the type of material, its dimensions, and its temperature.
The primary element contributing to resistance is the collisions between electrons and atoms within the material through which the current is passing.
When an electric current flows through a conductor, such as a wire, the electrons move along the path of the conductor. However, as they do so, they encounter resistance.
This resistance causes the electrons to collide with atoms, which generates heat and dissipates energy.

A geosynchronous satellite orbits Mars (mass = 6.42 x 1023 kg) once every Martian day, 88640 s. At what radius does it orbit?
Answer:
angular speed ω = 2PI / T rad/sec
ω^2*r = M*G/r^2
r = ³√ M*G/ω^2 = ³√6.42*10^23*6.67*10^-11*88640^2/39.5 = 2.04*10^7 m
Explanation:
A geosynchronous satellite orbits Mars once every Martian day, 88640 s then the radius of the orbit will be equal to 2.04 × 10⁷ m.
What is gravity?The fundamental force of attraction operating on all matter is recognized as gravity, also spelled gravity, in mechanics. It has no impact on identifying the interior properties of common matter because it is the weakest force known to exist in nature.
As per the given data in the question,
Mass, m = 6.42 x 10²³ kg
Time, T = 88640 s
Use the formula of velocity for satellite,
v = 2πR/T
Where R represents the radius
Use the formula of centripetal acceleration,
[tex]a_c[/tex] = v²/R
Thus;
[tex]a_c[/tex] = (2πR/T)²/R
= 4π²R/T²
The formula for gravitational acceleration is:
[tex]a_g[/tex] = Gm/R²
G = 6.674 × 10⁻¹¹ m³/kg. s²
Now, the satellite's gravitational acceleration is what is responsible for its centripetal acceleration. Thus,
Centripetal acceleration = gravitational acceleration.
Thus;
4π²R/T² = Gm/R²
Making R the subject gives;
R = ∛(GmT²/4π²)
Substitute the values in the above equation,
R = ∛((6.674 × 10⁻¹¹ × 6.42 x 10²³ × 88640²)/(4 × π²))
R = 2.04 × 10⁷ m

If Manuel exerts a force of 10 N to push a desk to the right at the same time Lynn exerts a force of 15 N to push the desk to the left, the desk will move to the
left
right
sideways
it won't move
Answer:
The desk will move to the left.
Explanation:
Since Manuel is exerting a force of 10 N to the right, and Lynn is exerting a force of 15 N to the left, it means that Lynn is exerting a force of 5 N more than Manuel, meaning that the desk will move to the left, the direction Lynn is pushing it too.

If the initial velocity of a ball is sent straight upward at 10.5m/s from the ground what will its final velocity be when it hits the ground at the end of its flight?
Answer: -10.08 m/s
Explanation:
Here we only need to analyze the vertical problem.
When the ball is in the air, the only force acting on it will be the gravitational force, this means that the acceleration of the ball, is equal to the gravitational acceleration, then:
a(t) = -9.8m/s^2
Where the negative sign is because gravity pulls the ball down.
To get the velocity equation we need to integrate over time, we get:
v(t) = (-9.8m/s^2)*t + v0
Where v0 is the initial vertical velocity, here it is v0 = 10.5 m/s
Then the velocity equation is:
v(t) = (-9.8m/s^2)*t + 10.5 m/s
To get the position equation, we need to integrate again over time, we get:
p(t) = (1/2)*(-9.8m/s^2)*t^2 + (10.5 m/s)*t + p0
Where p0 is the initial position, we know that the ball is sent upward from the ground, so p0 = 0m
Then the position equation is:
p(t) = (1/2)*(-9.8m/s^2)*t^2 + (10.5 m/s)*t
Now we need to find the value of t such that the position is equal to zero (this means that the ball hits the ground again).
Then we need to solve:
p(t) = 0 = (1/2)*(-9.8m/s^2)*t^2 + (10.5 m/s)*t
If we divide both sides by t, we get:
0 = (1/2)*(-9.8m/s^2)*t + (10.5 m/s)
Now we can solve it:
(1/2)*(9.8m/s^2)*t = 10.5 m/s
t = (10.5 m/s)/((1/2)*(9.8m/s^2)) = 2.14 s
This means that after 2.14 seconds, the ball will hit the ground again.
The velocity of the ball when it hits the ground is equal to:
v(2.14s) = (-9.8m/s^2)*2.14s + 10.5 m/s = -10.08 m/s

What is the final temperature when 625 grams of water at 75.0° C loses 7.96 x 10^4 J? (cwater = 4186 J/kg°C)
Answer: 44.57°C
Explanation:
The following can be deduced from the question:
Specific heat of water = 4.186 J/kg
From the question, we can infer that 625 × 4.186 joules of heat will be lost when there's a 1°C drop of water.
We then calculate the amount if degrees that it'll take to cool for 7.96 x 10⁴J. This will be:
= 7.96 × 10⁴ /(625 × 4.186)
= 79600/(625 x 4.186)
= 79600/2616.25
= 30.43°C
The final temperature will then be:
= 75.0°C - 30.43°C
= 44.57°C
How does wavelength change depending on whether the pipe is open or closed?
Answer:
* in a tube with both ends open
λ = 2L / n n = 1, 2, 3,…
* tube with one end open and the other closed.
λ = 4L / n n = (2n ’+ 1 )
Explanation:
When a sound wave enters a pipe, a resonance process occurs, whereby only some wavelengths can occur.
* in a tube with both ends open
in this case there are maximums at each end, so if the length of the had is L
λ = 2L 1st harmonic
λ = 2 L / 2 2nd harmonic
λ = 2L / 3
λ = 2L / n n = 1, 2, 3,…
* In the case of a tube with one end open and the other closed.
At the open end there is a belly and at the closed end a node
λ = 4L 1st harmonic
λ = 4L / 3 3rd harmonic
λ = 4L / 5
λ = 4L / n n = 1, 3, 5,… odd
n = (2n ’+ 1 ) where n’ are all integers
