Based on the information in the article, how could plants be used in the future to help counteract some human
emissions?
Answer:
Having more plants performing photosynthesis could help reduce the amount of carbon dioxide in the atmosphere.
Explanation:
sample answer
The plants can be used in the future to help counteract some human
emissions they absorb carbon dioxide from the air and release oxygen.
What is photosynthesis?It is a process carried out by photosynthetic autotrophic organisms, such as plants, algae and some prokaryotes. These organisms capture sunlight, convert it into chemical energy, which will be used to produce organic compounds, based on water and carbon dioxide.
Trees, like other plants, in the process called photosynthesis, absorb carbon dioxide from the air and release oxygen. They also make the air wetter and cooler. In this way, plants contribute to the good quality of the air we breathe.

Please help me calculate this question along with the equation
Hi there!
We can use the following:
U (Gravitational Potential Energy) = mgh
m = mass of object (kg)
g = acceleration due to gravity OR gravitational field strength
h = height, or displacement (m)
ΔU = Uf - Ui, so:
Uf = 3 × 1.5 × 10 = 45 J
Ui = 3 × 0 × 10 = 0
ΔU = Uf - Ui = 45 - 0 = 45 J
Find the acceleration if the force is 10 N and the mass is 5000 g.
Answer:
If the force is 10N and mass is 5000G, then a=2m/s2
Explanation:
F=10N
m=5000
g=5kg
a=10N/ 5kg
and finally; a= 2m/s2

b. Proton 2000 +1
c. Neutron 2000 0
2. a. An uncharged nucleon is neutron. It is a chargeless subatomic particle.
b. The particle with the least mass is electron. The mass of an electron is so small that it is considered to be negligible while calculating the atomic mass of an element.
c. The particle with the same mass as a neutron is proton. However if we see the absolute mass of neutron and proton then it is seen that neutron has a greater mass than proton.
d. The particle with the same amount of charge as an electron is proton. Note that the amount of charge is only same. Electron is negatively charged while proton is positively charged.
e. A particle that is negatively charge is electron. The relative charge of electron is -1.

Find the mass of the second object if the force of gravity between the two objects is 0.128N. The mass of the first object is 1300 kg and the 2 objects are 0.23 m apart.
Considering the Law of Universal Gravitation, the mass of the second object is 78090.19 kg.
The Law of Universal Gravitation is a law that states that bodies, by the simple fact of having mass, experience a force of attraction towards other bodies with mass, called gravitational force.
This law establishes that every particle attracts any other particle with a force directly proportional to the product of the masses of both and inversely proportional to the square of the distance that separates them:
[tex]F=G\frac{m1m2}{r^{2} }[/tex]
where m1 and m2 are their masses; r the distance between them and G a universal constant that is called the constant of gravitation.
In this case, you know:
F= 0.128 NG=6.67× 10⁻¹¹ Nm²/kg²m1= 1300 kgm2= ?r= 0.23 mReplacing:
[tex]0.128 N=6.67x10^{-11}\frac{Nm^{2} }{kg^{2} } \frac{1300 kg m2}{(0.23 m)^{2} }[/tex]
Solving:
[tex]0.128 N=1.639x10^{-6}\frac{N}{kg }x m2[/tex]
m2=0.128 N ÷ 1.639×10⁻⁶ [tex]\frac{N}{kg}[/tex]
m2=78090.19 kg
In summary, the mass of the second object is 78090.19 kg.

what is the magnitude of the torque that the axle must apply to prevent the disk from rotating?
The required torque at the axle, is given by the difference between the
moments of the applied forces.
The torque required is 19.62 N·m counterclockwise
Reasons:
The given parameters are;
Mass of the disk, m = 5.0 kg
Location of the axle = Half the radius of the disk
Diameter of the disk, D = 40 cm = 0.4 m
Applied mass, 0.1 m from the axle = 15 kg
Applied mass, 0.3 m from the axle = 10 kg
Required:
Magnitude of torque at the axle that prevent the disk from rotating
Solution:
Torque needed = Clockwise moment - Counterclockwise moment
Clockwise moment = (10 kg × 0.3 m + 5 kg × 0.1 m) × 9.81 m/s² = 34.335 N·m
Counterclockwise moment = 15 kg × 0.1 m × 9.81 m/s² = 14.715 N·m
τ + Counterclockwise moment = Clockwise moment
τ + 14.715 N·m = 34.335 N·m
Torque required, τ = 34.335 N·m - 14.715 N·m = 19.62 N·m
Torque required, τ = 19.62 N·m counterclockwise

A 4.6 kg bucket of water is raised from a well by a rope. The acceleration of gravity is 9.8 m/s 2 . If the upward acceleration of the bucket is 3 m/s 2 , find the force exerted by the rope on the bucket. Use g
Hi there!
If we sum the forces acting on the bucket:
∑F = T (upward) - Mg (downward)
Thus:
ma = T - mg
We can rearrange for T:
ma + mg = T
Plug in the given values:
4.6(3 + 9.8) = T = 58.88 N
A vinyl "record" with a diameter of 0.3 m is spinning at a rate of 1 m/s.
a) What would the centripetal acceleration be for a piece of gum (0.005kg) stuck to the outside edge of the record?
b) How much centripetal force will the gum have to overcome to remain "stuck" to the vinyl?
This question involves the concepts of centripetal force and centripetal acceleration.
a) The centripetal acceleration for the piece of gum stuck to the outside edge of the record will be "6.67 m/s²".
b) The gum will have to overcome "0.033 N" centripetal force to remain stuck to the vinyl.
a)
The centripetal acceleration of the gum can be found using the following formula:
[tex]a_c=\frac{v^2}{r}[/tex]
where,
[tex]a_c[/tex] = centripetal acceleration = ?
v = linear speed of record = 1 m/s
r = radius of the record = [tex]\frac{diameter}{2}=\frac{0.3\ m}{2}=0.15\ m[/tex]
Therefore,
[tex]a_c=\frac{(1\ m/s)^2}{0.15\ m}\\\\a_c = 6.67\ m/s^2[/tex]
b)
Now, the centripetal force can be given as follows:
[tex]F_c=ma_c\\F_c=(0.005\ kg)(6.67\ m/s^2)\\F_c=0.033\ N[/tex]

Answer:
For example, an earthquake of magnitude 5.5 releases about 32 times as much energy as an earthquake measuring 4.5. Another way to look at this is that it takes about 900 magnitude 4.5 earthquakes to equal the energy released in a single 6.5 earthquake.
Explanation:
