What process is represented by this redox equation ? 6H 2 O+6CO 2 C 6 H 12 O 6 +6O 2
Answer:
C. Photosynthesis
Explanation:
The redox reaction given in this question is given as follows:
6H2O + 6CO2 → C6H12O6 + 6O2
In this reaction, water (H2O) reacts with carbon dioxide (CO2) to form glucose (C6H12O6) and oxygen (O2). This is the general equation for PHOTOSYNTHESIS process, which is the process whereby plants manufacture their food (sugar) by combining water and carbon dioxide.
In the equation above, water is oxidized into oxygen, while carbon dioxide is reduced into glucose. This makes it an oxidation-reduction (redox) reaction.
Which statement explains how planets move in orbit as supported by Newton’s first law of motion?
Planets can change the direction of their own orbital path.
Planets can change orbits due to their inertia.
Planets in motion will have a constant speed unless acted on by an outside force.
Planets with a greater mass will orbit more quickly than smaller planets.
Answer:
C
Explanation:
When the planet in motion should have the same speed so until it should be acted by an outer force. This statement explained the movement of the planets.
The information regarding the first law of motion is as follows:
In the case when the body is at rest or moves at the same speed on the straight line so it should be the same at rest or a movement until it is acted by an outside force. It is also called as law of inertia.Therefore, the third option is correct.

True or False: While steroids are not allowed in chicken production, selective breeding has caused chickens to grow very large, very quickly.
1. True
2. False
Answer:
True.
Explanation:
In biology, selective breeding is the mechanism by which certain traits or a combination of traits are consciously selected in animal breeding or plant breeding and cultivation. Artificial selection is seen as a counterpart to natural selection, the mechanism by which, in nature, individuals are selected who are better adapted to their natural environment. Both processes have the same genetic principles and background. Man selects the individuals with the desired traits to produce progeny, making these traits more and more common.

9. Bryce drove his car 10 km from his house to Belle Plaine. It took him 8 minutes. He got stopped at a long
traffic light on the return home and so he took 2 minutes longer on the return trip. What was Bryce's average
speed in km per minute? (3 pt)
Answer:
2 km/minuteExplanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Average speed = Total distance ÷ Total time takenHere,
→ Total distance = 10 km + 10 km
Because, he first drove 10 km from his house to Belle Plaine and then he again came back to his house.→ Total distance = 20 km
→ Total time = 8 minutes + 2 minutes
→ Total time = 10 minutes
Substitute the values in the formula of average speed,
→ Average speed = Total distance ÷ Total time taken
→ Average speed = 20km ÷ 10 minutes
→ Average speed = 2 km per minuteA solid metal ball with a mass of 10.0 kg is placed on a smooth floor what force would be needed to accelerate the ball at a rate of 2.0 m/s2.

An object is 10.0 cm from a plane mirror. The object is 5.00 cm tall.
a. What is the image position?
Answer:
...............
Explanation:
If an object is placed in front of a plane mirror, the size of the object remains same. This is the property of plane mirror. So the height of the object will be 10cm only.
The image position in the plane mirror is 5 cm.
What is meant by magnification ?The ratio of the height of the formed image to the height of the object is used to define the magnification created by the mirror.
Here,
Position of the object, u = -10 cm
Height of the object, h = 10 cm
We know that magnification produced by a plane mirror is 1.
So,
Magnification, m = -v/u
1 = -v/u
Therefore, image distance,
v = -u
v = 5 cm
Hence,
The image position in the plane mirror is 5 cm.

A ___ is a large ball of gas that generates its own energy. This energy is created by the fusion of ___ atoms to make ___.
Answer:
Star, hydrogen and energy
Explanation:
A star is a large ball of gas that generates its own energy by fusing hydrogen atoms to make helium. It is held together by its own gravity. This process emits a tremendous amount of energy, and some of the energy is in the form of light.
The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
According to the graph, how many atoms would remain after two half-lives?
20 atoms
80 atoms
40 atoms
50 atoms
Answer:
Let No be initial no of atoms
N = N0 / 2 after 1 half-life
N = N0 / 4 after 2 half-lives
So after 2 half-lives 20 of the 80 atoms remain
1. Peter throws four stones having the same weight on four different surfaces. The surfaces aee icy, sandy, dry and cemented. He throws the stones with the dame force. On whoch of the given surfaces will the stone go to the maximum speed before it stops?
2. ____ is the body shape which offers very little resistance to the flow of air.
3. Spring balance is a device used for measuring the ______ of an object
Answer:
1. Icy
This is so because the icy surface will be slippery due to ice and water residue on it. Not only the stone, anything that goes on the icy surface is likely to slip. There won't be much friction offered by the surface.
If we talk about the sandy surface, the stone won't go far and will be stopped at the nearest point possible and it's also possible that the stone will settle down in the surface.
The dry and cemented surfaces will cause friction when the stone will be thrown on them, which will stop the stone from going far away.
2. Streamline is the body shape which offers very little resistance to the flow of air.
3. Spring balance is a device used for measuring weight of an object object.

How much work is done by 0.070 m3 of gas, when the volume remains constant with pressure of 63 x 105 Pa?
Answer:
W = 0 J
Explanation:
The amount of work done by gas at constant pressure is given by the following formula:
[tex]W = P\Delta V[/tex]
where,
W = Work done by the gas
P = Pressure of the gas
ΔV = Change in the volume of the gas
Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:
[tex]W = P(0\ m^3)\\[/tex]
W = 0 J

Three 18-ohm resistors are connected in series with an ideal 12-volt battery. What is the equivalent resistance of the circuit?
Answer:
RT = 54 Ohms
Explanation:
Given the following data;
Resistance = 18 Ohms
Voltage = 12 Volts
To find the equivalent resistance (RT) of the circuit;
For a series connection, the formula is;
RT = R1 + R2 + R3
RT = 18 + 18 + 18
RT = 54 Ohms
Or
RT = 3*R
RT = 3 * 18
RT = 54 Ohms

what would be the final temperature of a mixture of water at 40 degree celsius temperature and 60 grams of water at 80 degree celsius temperature
Answer:
T = 60°C
Explanation:
We are given;
Mass of water in both cases as 60g.
Thus; m1 = m2 = 60 g
Temperature of first water; T1 = 40°C
Temperature of 2nd water; T2 = 80°C
Let final temperature be T.
To solve for the final temperature, we will use the formula;
(m1 + m2)T = ((m1•T1) + (m2•T2))
(60 + 60)T = ((60 × 40) + (60 × 80))
120T = 7200
T = 7200/120
T = 60°C

8. Gravity pulls a skydiver down as air
friction (drag) pushes the skydiver up. Is
this an action-reaction pair?
Answer:
Air resistance is pushing up on the parachute and force of gravity is pulling down so she slows down. This increases friction which slows free fall down. So when the skydiver reaches terminal velocity, the force of gravity is balance by air resistance. But when the forces are balance, there is no acceleration.
Which is not true about the role of gravity in the formation of planets?
Dust and gas particles that were attracted to each other began to rotate into a protoplanetary disk.
Gravity between planetesimals caused them to join together into conglomerate clumps. Our solar system is the only place in the universe where gravity played a key part in the formation of planets.
Gravity of larger objects in orbit around the sun attracted, and cleared the orbital path of, smaller planetesimals, gas, and dust.
Our solar system is the only place in the universe where gravity played a key part in the formation of planets.

calculate the heat required to change 2.0kg of ice at 0°C to water at 0°C
Answer:
160000 calories or 669440 Joules
Explanation:
Using the formula as follows;
Q = L × m
Where;
Q = amount of heat (J)
L = specific latent heat
m = mass (g)
* Latent heat (L) required for melting of ice is 80 calories/grams.
* Mass of ice in grams = 2kg × 1000 = 2000g.
Hence, Q = 80 × 2000
= 160000 Calories
1 calorie = 4.184J
160000 calorie = 160000 × 4.184
= 669440J

The force exerted by water and air on the skier is 50 Newtons (N) to the left. The force exerted by the boat on the skier is 40 Newtons (N) to the right. How will the unbalanced forces change the motion of the skier
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Net force on a body.
We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,
and if the net force on a body is Zero, then it is a balanced force,
here,
Force to left on skier = 50 N
Force to right on skier = 40 N
hence the net force = left force - right force
Net force = 50 - 40 ==> 10 N
hence the Net force is 10 N in the left direction of the skier.
