4200 N is the tension in the cable that pulls the elevator upwards.
The correct option is A.
<h3>What does tension ?</h3>
Tension is the force that is sent through a rope, thread, or wire whenever two opposing forces pull on it. Along the whole length of the wire, the tensile stress pulls equally on all objects at the ends. Every physical object that comes into contact with that other one exerts force on it.
<h3>Briefing:</h3>
We employ the following formula to determine the cable's tension.
Formula:
T = mg+ma............ Equation 1
Where:
T is the cable's tension.
M = Mass of the elevator and the Joey
Accelerating with a
g = Gravitational acceleration
Considering the query,
Given:
m = (300+60) = 360 kg
a = 2 m/s²
g = 9.8 m/s²
Substitute these values into equation 2
T = (360×9.8)+(360×2)
T = 3528+720
T = 4248 N
T ≈ 4200 to the nearest hundred.

Answer:
If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object (that is, the object with the greater temperature) to the colder (lower temperature) object, until both objects are at the same temperature
Matter> anything that has mass and takes up space.
Then it’s pure substances (goes on right) then definition is the one that is, “matter that only has 1 set of chemical and physical properties” > divides into compounds and elements. The detention of compounds is, contains two or more elements chemically bonded together.
Oxygen, is under elements.
Then on the left goes mixture; definition, “
Under compounds goes sodium, co2, h2o
under it goes homogeneous (left) def: “more than 1 type of matter that looks different through” and heterogeneous (right Im sure). Def. of heter is, “two or more substances chemically combined and can be separated.”
Under heter goes; soil and blood
Under homo: kool aid,
Chex mix and cake batter
That’s what I’ve gotten so far
Answer:
Velocity=0.2m/s
Explanation:
Velocity=displacement / time
Velocity=7.6m/38s
Velocity=0.2m/s
