How is a plant able to cycle matter through the processes of cellular respiration and photosynthesis?
The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.
How photosynthesis and cellular respiration are similar:
Photosynthesis is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration.

Dimas reads that it takes 270 N to lift a firefighter's equipment. If a firefighter does 5400 J of work carrying the equipment up a staircase, how high does the firefighter climb? (Work: W = Fd) 20 m 200 m 5130 m 1,458,000 m
Answer:
h = 20 m
Explanation:
Given that,
Force to lift a firefighter's equipment, F = 270 N
Work done, W = 5400 J
We need to find the height climbed by the firefighter. We know that,
Work done, W = Fd
So,
[tex]d=\dfrac{W}{F}\\\\d=\dfrac{5400}{270}\\\\d=20\ m[/tex]
So, the firefighter climb from a height of 20 m.

Q1) Calculate the gravitational force between two large trucks, each with a mass of 6500 kg, if
they are parked next to each other separated by a distance of 0.5 m Ignore all other
gravitational forces.
Answer:
F = 0.0112 N
Explanation:
Given that,
Masses, [tex]m_1=m_2=6500\ kg[/tex]
The distance between masses, d = 0.5 m
We need to find the gravitational force between two large trucks. The formula for the gravitational forces is given by :
[tex]F=G\dfrac{m^2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{6500^2}{(0.5)^2}\\\\F=0.0112\ N[/tex]
So, the required force between masses is equal to 0.0112 N.
Increasing the force acting on an object increases its acceleration.

Amy pulls a spring with a spring constant k = 100 stretching it from its rest length of 0.10 m to 0.2
Answer:
Elastic potential energy E = 0.5 J
Explanation:
Let us assume we have to find the elastic potential energy stored in the spring.
Given: k = 100
change in the length of the spring x = 0.2-0.1 = 0.1 m
Elastic potential energy
E = [tex]\frac{1}{2} kx^2[/tex]
plugging the values we get
[tex]E = 0.5\times100\times0.1^2\\=0.5 J[/tex]
Hence, Elastic potential energy E = 0.5 J
Amy pulls a spring with a spring constant k = 100 N/m, stretching it from its rest length of 0.10 m to 0.20 m.
What is the elastic potential energy stored in the spring?
Answer: 0.5 J

You cannot classify matter based on chemical properties. true or false?
Answer:
ture i think
Explanation:
It is false that one cannot classify matter based on chemical properties.
What is a matter?Matter is the scientific term for any type of material. Matter is defined as anything with mass that occupies space.
Matter requires at least one subatomic particle, though most matter is made up of atoms. A pure substance is sometimes referred to as matter.
Solids, liquids, and gases are the three forms or phases of matter. A substance is defined as matter that is homogeneous and has identical parts.
Substances are classified as either elements or compounds. Elements are pure substances that cannot be chemically decomposed into simpler substances.
Chemically, matter can be classified as pure substance elements and compounds, mixture, or impure substance.
Thus, the given statement is false.

An object moves from point A to B to C to D and finally to A
along the circle shown in the figure below.
a) Find the distance covered by the moving object.
b) Find the magnitude of the displacement of the object.
Answer:
a) The distance covered by the moving object is approximately 18.85 km
b) The magnitude of the displacement of the object is 0 (no displacement)
Explanation:
From the drawing, we have;
The sale of the drawing is 1 unit = 1 km
The radius of the circle in the drawing along which the object moves = 3 units
Therefore;
The radius of the circle along which the object moves, r = 1 km/unit × 3 units = 3 km
a) The distance covered by the object that moves from point A to B to C to D and finally to A is equal to the circumference of the circle
Therefore;
The distance covered by the moving object, d = 2·π·r
By pugging the value for r = 3 km
d = 2 × π × 3 km = 6·π km ≈ 18.85 km
The distance covered by the moving object, d ≈ 18.85 km
b) The displacement = The object's change in position
The initial position of the object = Point A
The final position of the object = Point A
Therefore, the displacement of the object, A = No displacement = 0 (No difference between the initial and final location of the object
There are some ways objects in motion are affected. _______________, or pushes and pulls, affect the motion of an object. _______________ is a force that pulls objects down to Earth. _______________ is a force that slows things down or can even make them stop. Did you know acceleration means more than the increase of an object’s speed? It also describes an object that is slowing down or changing _______________. Since acceleration is a change in speed or direction, that means, _______________ is a change in velocity
Answer:
Forces, Gravity, Friction, Direction, Acceleration.
The answers for the fill-in-the-blanks would be Force, gravity friction
direction and acceleration respectively.
What is gravity?It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another,
There are a few ways that moving objects are impacted. Pushes and pulls, or force, have an impact on how an object moves.
The force of gravity drags items toward the Earth.
Friction is a force that causes objects to move more slowly or even come to a stop.
It also applies to an item that is reversing course or slowing down. Since acceleration is a change in velocity, it can also be a change in speed or direction.
Thus, Force, gravity friction direction, and acceleration are the answers respectively.

A student shakes a rope such that 20 complete vibrations are made in 4.00 seconds. Determine the vibrational frequency of the rope, along with the corresponding unit.
Answer:
The vibrational frequency of the rope is 5 Hz.
Explanation:
Given;
number of complete oscillation of the rope, n = 20
time taken to make the oscillations, t = 4.00 s
The vibrational frequency of the rope is calculated as follows;
[tex]Frequency = \frac{number \ of \ complete \ vibrations}{time \ taken} \\\\Frequency = \frac{20 }{4 \ s} \\\\Frequency = 5 \ Hz[/tex]
Therefore, the vibrational frequency of the rope is 5 Hz.
Blue-ray disc accelerates from rest to a constant rotational speed of 466 rpm, it rotates through an angular displacement of 0.250 rev. What is the angular acceleration of the CD?
Answer:
[tex]\alpha =434312\ rev/s^2[/tex]
Explanation:
Given that,
Initial angular speed, [tex]\omega_i=0[/tex]
Final angular speed, [tex]\omega_f=466\ rpm[/tex]
Angular displacement, [tex]\theta=0.25\ rev[/tex]
We need to find the angular acceleration of the CD. Using third equation of rotational kinematics as follows :
[tex]\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{466^2-0^2}{2\times 0.25}\\\\\alpha =434312\ rev/s^2[/tex]
So, the angular acceleration of the CD is equal to [tex]434312\ rev/s^2[/tex].

An aircraft is moving horizontally with a speed of 50m/s, at the height of 2km, an object is dropped from the aircraft. What is the vertical and horizontal velocity of an object if the angle is 23 degrees and the time interval for the object hits the ground?
Explanation:
use the diagram^
horizontal velocity of the object nvr changes, it'll stay 50m/s till it hits the ground
initial vertical velocity = 0
to find the final vertical velocity, use the formula:
[tex]v {}^{2} = u {}^{2} + 2as[/tex]
where u = 0m/s, a = 9.8m/s², and s = 2000m
solve for v.
for time taken to reach ground, use the formula:
[tex]v = u + at[/tex]
where v = the value for v u calculated above, u = 0 m/s, a = 9.8m/s² and solve for t.
14. A light bulb has a resistance of 8 ohms and a maximum current of 10 A How much voltage can
be applied before the bulb will break?
Answer:
80 volts.
Explanation:
From the question,
Applying Ohm's law
V = IR...................... Equation 1
Where V = Voltage, I = maximum current of the bulb, R = Resistance of the bulb.
Given: I = 10 A, R = ohms
Substitute these values into equation 1
V = 10×8
V = 80 volt.
Hence the voltage that can be applied is 80 volt.
