provide the reactants needed to start cellular respiration

Explanation:

The thing you should know is that photosynthesis is exactly opposite from cellular respiration.

the products of photosynthesis are the oxygen and the organics.

And the oxygen and the organics are also the reactants of the cellular respiration.

Answer:

Reaction

Explanation:

Answer: A

Potential energy = 14.7 J

Explanation:

Given that the

Mass M = 5 kg

Height h = 0.3 m

Let us take acceleration due to gravity g = 9.81 m/s^2

Potential energy = mgh

Substitute all the parameters into the formula above

P.E = 5 × 9.81 × 0.3

P.E = 14.715 J

P.E = 14.7 J approximately

The correct option is therefore A

Answer:

The other bulbs would stay lit.

Explanation:

You're just unscrewing one bulb, not turning off the circuit.

Explanation:

We have,

Force acting on the mass is 310 N

Mass, m = 120 kg

Distance covered by the mass is 30 m

Time, t = 3 s

To find,

(a) Work done (b) power developed

Solution,

(a) The work done on the mass is given by the product of force and displacement such that,

[tex]W=Fd\\\\W=310\times 30\\\\W=9300\ J[/tex]

(b) The rate at which the work is done is called power developed. Its formula is given by :

[tex]P=\dfrac{W}{t}\\\\P=\dfrac{9300}{3}\\\\P=3100\ W[/tex]

Therefore, the work done on the mass is 9300 J and the power developed is 3100 W.

Answer:

i do not know is your are talking about boyfriend and girlfriend relationship of you are talking about friendship i am just going to say both so for a friendship they do not have to like the same thing but if they do that is cool they have to be nice to each other and understand what one of them wants to do and they have to get along if they want to have a goof friendship so for boyfriend and girlfriend it is okay for them to fight and not understand each other they have to be friends so they can no what they like to do with each other then they can go on dates together

Answer:  Rancho de Area Comunes PV

Explanation: it means

Rancho de Area Comunes PV

In an AC Monte Roca PV System Profile, where the following are depicted:

Location

Production

Operator

PV system power

Module

And communication.

Answer: time t = 2 seconds

Explanation:

Given that

Power P = 50W

Energy E = 100J

How long did it take to move the box from the floor to the shelf ? This implies time taken.

Power is defined as the rate at which work is done. I.e

P = W.D/t

Where work done = energy

50 = 100/t

Make t the subject of formula

t = 100/50

t = 2 second

Answer:

1.Work done=100 joules

2.potential energy

3.kinetic energy

Explanation:

W=Force x distance

w= 20 N x 5 M

W = 100 JOULES

Answer:

Force, [tex]F=2.88\times 10^{-3}\ N[/tex]

Explanation:

Charge 1, [tex]q_1=1\times 10^{-7}\ C[/tex]

Charge 2, [tex]q_2=-2\times 10^{-7}\ C[/tex]

Distance between charges, d = 0.25 m

It is required to find the force between charges. The charges are opposite the force between them is attractive. The force between charges is given by :

[tex]F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 1\times 10^{-7}\times 2\times 10^{-7}}{(0.25)^2}\\\\F=2.88\times 10^{-3}\ N[/tex]

So, the force between charges is [tex]2.88\times 10^{-3}\ N[/tex].

Answer:

Red line is reflected ray.

Explanation:

According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.

After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.

In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.

Answer:

(A.) H2 --> 2H+ 2 e- (oxidation)

Explanation:

A. oxidation is the removal of electron(s) from a substance. This is the case here, since AFTER the reaction you can see that there were electons "removed" from H2.

H2 --> 2H+ 2 e- (oxidation)

B. reduction is the addition of electron(s) to a substance

1/2 O2 + 2 e- + 2H+ --> H2O (reduction)

By the way:

Biochemical reactions often involve the transfer of complete hydrogen atoms, meaning an electron and a proton.

The substance oxidized (H2) is electron donor.

The substance reduced (O2) is electron acceptor.

Just remember this:

Prior to the reaction, the e donor is always reduced.

Prior to the reaction, the e acceptor is always oxidized.

Answer:

Force

Explanation:

The mass of an object is the quantity of matter it contains. It is measured in kilograms.

Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].

When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.

i.e     F = m × a

where F is the force, m is the mass of the object and a its acceleration.

The two major classes of force are; contact force and field force.

Answer:

Density is independent of the

amount of the sample. (D)

Explanation:

Because density is an intrinsic property of matter.

hope it helps!

Answer:

D. Density is independent of the

amount of the sample.

Explanation:

Density is expressed in units of mass per volume, such as g/mL or kg/m3. Because the density of a substance does not depend on the amount of substance present, density is an “intensive property”. To measure the density of a sample of material, both the mass and volume of the sample must be determined.

When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. ... The earth spins around the geographic poles, but magnetic compasses point to the magnetic poles.

Answer:

It states that a graph is perfect if the sizes of the largest clique, and the largest independent set, when multiplied together, equal or exceed the number of vertices of the graph, and the same is true for any induced subgraph

Answer:

When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement. If you throw a ball, you are pushing on it to start its movement. If you drop an object, the force of gravity causes it to move.

Answer:

G

Explanation

The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.

Answer G: speed=v, distance =d.

Answer:

B

Explanation: yes

Answer:

1.82 cm

Explanation:

The relationship between the object distance (p), image distance (q) and focal length (f) is given by [tex]\frac{1}{p}+\frac{1}{q}=\frac{1}{f}[/tex]

According to question,

Object distance (p) = 3.28 cm

Image distance (q) = 4.11 cm

Therefore,

[tex]\frac{1}{3.28}+\frac{1}{4.11}=\frac{1}{f}\\\frac{3.28+4.11}{3.28\times 4.11}=\frac{1}{f}\\f=\frac{3.28\times 4.11}{3.28+4.11}\\=\frac{13.48}{7.39}\\=1.82\,\,cm[/tex]

Answer:

Hope this helped :

Explanation:

When light passes from a medium with one index of refraction (m1) to another medium with a lower index of refraction (m2), it bends or refracts away from an imaginary line perpendicular to the surface (normal line). As the angle of the beam through m1 becomes greater with respect to the normal line, the refracted light through m2 bends further away from the line.

At one particular angle (critical angle), the refracted light will not go into m2, but instead will travel along the surface between the two media (sine [critical angle] = n2/n1 where n1 and n2 are the indices of refraction [n1 is greater than n2]). If the beam through m1 is greater than the critical angle, then the refracted beam will be reflected entirely back into m1 (total internal reflection), even though m2 may be transparent!
