The force of tension supporting the elevator is 400.0 N
To find the force of tension supporting the elevator, we need to find the acceleration of the elevator from the gradient of the graph.
So, a = Δv/Δt = (v₂ - v₁)/(t₂ - t₁) where v₁ = 2 m/s, t₁ = 0 s, v₂ = 6 m/s and t₂ = 6 s
So, a = (6 m/s - 2 m/s)/(6 s - 0 s)
a = 4 m/s ÷ 6 s
a = 2/3 m/s²
a = 0.67 m/s²
So, the force of tension on the elevator, T = ma where m = mass of elevator = 600 kg and a = acceleration of elevator = 2/3 m/s².
So, T = ma
T = 600 kg × 2/3 m/s²
T = 400 N
So, the force of tension supporting the elevator is 400.0 N

Why does plasma challenge what we know about matter? How does it confirm what we already know?
Being made of charged particles, plasmas can do things gases cannot, like conduct electricity. And since moving charges make magnetic fields, plasmas also can have them. In an ordinary gas, all the particles will behave roughly the same way. Auroras, lightning, and welding arcs are also plasmas; plasmas exist in neon and fluorescent tubes, in the crystal structure of metallic solids, and in many other phenomena and objects. The Earth itself is immersed in a tenuous plasma called the solar wind and is surrounded by a dense plasma called the ionosphere.
Plasma is a type of matter in which many electrons freely roam around the nuclei of atoms.
What is plasma?Although plasma is commonly thought of as a subset of gases, the two states behave very differently. Plasmas, like gases, have no definite shape or volume and are denser than solids or liquids.
Plasma is a sort of matter in which numerous electrons freely roam around the nuclei of atoms.
Plasma has been described as the fourth state of matter, alongside solid, liquid, and gas.
Normally, electrons in a solid, liquid, or gaseous sample of matter remain bound to the same nucleus.
Thus, plasma is considered a distinct phase because it does not conform to the standard descriptions and physical laws that are used to describe the standard three states of matter.

PLEASE HELP ASAP! WILL GIVE BRANLIEST! Pay attention to what happens to the things around you as you go about your day. Describe three examples of Newton’s third law in action. In your examples describe the action and the equal and opposite reaction.
Answer:
jumping, pulling a elastic band, bouncing a ball
Explanation:
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
When we pull an elastic band, it automatically returns to its original position. The more you pull the more force it generates. This is the same when you pull or compress a spring. The action (applied force) is stored as energy and is released as a reaction with an equal and opposite force
A ball is able to bounce because of the reaction from the ground. If there was no reaction then the ball would not bounce but rather stick to the ground.

11 An aeroplane is travelling horizontally at a speed of 80 ms", and drops a crate of emergency supplies
(Figure 2.39). To avoid damage, the maximum vertical speed of the crate on landing is 20 ms.
You may assume air resistance is negligible.
80 ms
Figure 2.39 For End-of-chapter Question 11.
a Calculate the maximum height of the aeroplane when the crate is dropped.
b Calculate the time taken for the crate to reach the ground from this height.
• The aeroplane is travelling at the maximum permitted height Calculate the horizontal distance travelled
by the crate after it is released from the aeroplane.

a.
The maximum height of the aeroplane when the crate is dropped is 20.41 m
Using v² = u² - 2gs where u = initial vertical speed of crate = -20 m/s(since it is falling), v = final vertical speed of crate = 0 m/s (since it stops immediately it lands), g = acceleration due to gravity = 9.8 m/s² and s = maximum height of airplane when crate is dropped.
So, making s subject of the formula, we have
s = -(v² - u²)/2g
Substituting the values of the variables into the equation, we have
s = (v² - u²)/2g
s = -((0 m/s)² - (-20 m/s)²)/(2 × 9.8 m/s²)
s = -(-400 m²/s²)/(19.6 m/s²)
s = 400 m²/s²/19.6 m/s²
s = 20.41 m
So, the maximum height of the aeroplane when the crate is dropped is 20.41 m
b.
The time taken for the crate to reach the ground from maximum height is 2.041 s
Using v = u + gt where u = initial vertical speed of crate = -20 m/s(since it is falling), v = final vertical speed of crate = 0 m/s (since it stops immediately it lands), g = acceleration due to gravity = 9.8 m/s² and t = time taken for the crate to reach the ground from maximum height.
Making t subject of the formula, we have
t = (v - u)/g
Substituting the values of the variables into the equation, we have
t = (v - u)/g
t = (0 m/s - (-20 m/s))/9.8 m/s²
t = (0 m/s + 20 m/s))/9.8 m/s²
t = 20 m/s/9.8 m/s²
t = 2.041 s
So, the time taken for the crate to reach the ground from maximum height is 2.041 s
c.
The horizontal distance travelled by the crate after it is released from the aeroplane is 163.27 m
Since the horizontal velocity of the crate is the horizontal velocity of the crate, we calculate the horizontal distance the crate travelled after it is released from the aeroplane.from
d = Vt where V = horizontal velocity of crate = 80 m/s and t = time taken for crate to drop from maximum height = 2.041 s.
So, substituting the values of the variables into the equation, we have
d = Vt
d = 80 m/s × 2.041 s
d = 163.27 m
So, the horizontal distance travelled by the crate after it is released from the aeroplane is 163.27 m
