Cellular respiration occurs in every cell of our bodies. Through this process, we obtain the energy we need for life. During cellular respiration, oxygen helps in breaking down sugar molecules into carbon dioxide and water molecules. Which reaction correctly represents the cellular respiration process?(1 point)
carbon dioxide + water → sugar + oxygen + energy
sugar + oxygen → carbon dioxide + water + energy
carbon dioxide + water + energy → sugar + oxygen
sugar + oxygen + energy → carbon dioxide + water
Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
The reaction which correctly represents the cellular respiration process is sugar + oxygen → carbon dioxide + water + energy.

A wave with a wavelength of 125 meters is moving at a speed of 20 m/s. What is it’s frequency
Answer:
0.16Hz
Explanation:
wavelength (λ) = 125 meters
speed (V) = 20 m/s
frequency (F) = ?
Recall that frequency is the number of cycles the wave complete in one
second. And its value depends on the wavelength and speed of the wave.
So, apply the formula V = F λ
Make F the subject formula
F = V / λ
F = 20 m/s / 125 meters
F = 0.16 Hz

Answer:
For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped. So, a sound wave 's amplitude decreases as it moves through a medium.

A bullet is fired in a horizontal direction with a muzzle velocity of 300m/s.In the absence of air resistance,how far will it have droppped in travelling a horizontal distance of how far it will drop one one second
Answer:
304.9m
Explanation:
Given
Velocity = 300m/s
Tim = 1sec
Required
Horizontal distance S
Using the formula
S= ut+1/2gt²
S = 300(1)+1/2(9.8)(1)²
S = 300+4.9
S = 304.9m
Hence the distance travelled is 304.9m
Consult Multiple-Concept Example 5 for insight into solving this problem. A skier slides horizontally along the snow for a distance of 12.4 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is 0.0368. Initially, how fast was the skier going
Answer:
The speed with which the skier was going is approximately 2.9906 m/s
Explanation:
The given parameters are;
The distance the skier slides before coming to rest, s = 12.4 m
The coefficient of friction between the skier and the snow, [tex]\mu _k[/tex] = 0.0368
Therefore, for conservation of energy, we have;
Initial kinetic energy = Work done by the kinetic friction force
Initial kinetic energy = 1/2·m·v²
The work done by the kinetic friction force = [tex]\mu _k[/tex]×m×g×s
Where;
m = The mass of the skier
v = The speed with which the skier was going
g = The acceleration due to gravity = 9.8 m/s²
s = The distance the skier slides before coming to rest = 12.4 m
[tex]\mu _k[/tex] = The kinematic friction = 0.0368
Therefore, for conservation of energy, we have;
1/2·m·v² = [tex]\mu _k[/tex]×m×g×s
1/2·v² = [tex]\mu _k[/tex]×g×s
v² = 2×[tex]\mu _k[/tex]×g×s = 2 × 0.0368 × 9.8 × 12.4 = 8.943872
v = √(8.943872) ≈ 2.99063070271 ≈ 2.9906 m/s
The speed with which the skier was going = v ≈ 2.9906 m/s.
have you ever wondered how clouds make shapes?
Answer:
Yes because
Explanation:
Clouds get their shapes from the air that surrounds them. ... Since clouds are made up of millions of tiny pieces of water, when they are really high up in the sky where the air is very cold, the water droplets freeze into floating ice crystals. When we observe these clouds way up in the sky, they look like wispy strands
A wave has a speed of 65 m/s and a frequency of 13 Hz. What is the wavelength of
this wave in metres?
Answer:
Explanation:
Velocity or speed (v) = 65 m/s
Frequency (F) = 13 Hz
Wavelength (λ) = ?
We know
V = λ * f
65 = λ * 13
λ = 65 / 13
Therefore Wavelength (λ) = 5 meters
Hope it will help :)
The wavelength of the wave is 5 m.
The given parameters;
velocity of the wave, v = 65 m/s
frequency of the wave, f = 13 Hz
The wavelength of the wave is calculated as follows;
v = fλ
where;
λ is the wavelength of the waveThe wavelength of the wave is calculated by substituting the given parameters;
[tex]\lambda = \frac{v}{f} \\\\\lambda = \frac{65}{13} \\\\\lambda = 5 \ m[/tex]
Thus, the wavelength of the wave is 5 m.

It's 5 kilometers from my house to the gym. If I walk to the gym and back home how many meters have I traveled
Answer:
10 km
Explanation:
Distance is a measurement of the length of space between two points or objects. Distance is a scalar quantity, that is it has magnitude and no direction. The S.I unit of distance is meter, but other units are inches, kilometers, mile and so on.
Total distance traveled = distance from house to gym + distance from gym back to the house
Total distance traveled = 5 km + 5 km
Total distance traveled = 10 km

Explanation:
Using the equation with both the minimum and where you're solving for d, (1-1/2) 675/sin(0.111), you get 174210.2 so you convert that into millimeters by moving the decimal point up 6 (the difference of nm 10^-9 and millimeters 10^-3),leaving you with 0.174.

A boat of mass 1,300 kg that is moving at a speed of 6 m/s and
a speedboat of mass 850 kg that is moving at a speed of 25
m/s. What's the total linear momentum of the boat and the
speedboat?
Answer: 29,050
Explanation:
If you notice this is a add and multiply problem .
All you are doing is finding the total linear momentum .
You would multiply 1,300 x 6= 7800
Then you would also multiply 850 x25=29050
You would add both of them (7800+21250)
And your final answer would be 29050kg •m/s
An object weighs 100 newtons on earth.What is its weight on the moon?
Answer:
a) The gravitational acceleration at the surface of the Moon is g moon=1.67 m/s

The ratio of weights (for a given mass ) is the ratio of g-values, so
W
moon
=(100N)(1.67/9.8)=17N.
(b) For the force on that object caused by Earth's gravity to equal 17 N, then the free fall acceleration at its location must be

=1.67m/s
2
. Thus , .

=2.4 "radii" from Earth's center.
Answer:
20 N
Explanation:
Consider that earth's acceleration due to gravity is approximately 9.81 m/s^2. Also consider that the moon's acceleration due to gravity is about 1.62 m/s^2. Using these two values, we can easily find the weight of the object on the moon, given that the object weighs 100 N, and that F = ma.
First, let's break it up.
100/9.81 =
10.193679918450561 kg
10.193679918450561*1.62 =
16.513761467889908 N
≈ 20 N (with one significant digit, since that is the least amount of sig figs in the problem)
