Here photosynthesis in a nutshell. Can you explain what is happening?

Answer:

Both will turn red

Both will turn blue

X will turn red and Y will turn blue

X will turn blue and Y will turn red

Answer:

X will turn blue and y will turn red

Explanation:

Since X has a pH of 9, it will turn blue because anything with a pH higher than 7 turns blue. Since Y has a pH of 4, it will turn red because anything with a pH lower than 7 turns red.

Answer:

Given: 6 questions with certain values of mass and acceleration.

To find: The amount of force?

Solution:

An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                    F = m x a = 2 x 2 = 4 N

An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                     F = m x a = 5 x 8 = 40 N

An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

Now in this mass is in grams, so converting it kg, we get:

                    1500/1000 kg = 1.5 kg

                   F = m x a = 1.5 x 10 = 15 N

Answer:

a. The total momentum of the trolleys which are at rest before the separation is zero

b. The total momentum of the trolleys after separation is zero

c. The momentum of the 2 kg trolley after separation is 12 kg·m/s

d. The momentum of the 3 kg trolley is -12 kg·m/s

e. The velocity of the 3 kg trolley = -4 m/s

Explanation:

a. The total momentum of the trolleys which are at rest before the separation is zero

b. By the principle of the conservation of linear momentum, the total momentum of the trolleys after separation = The total momentum of the trolleys before separation = 0

c. The momentum of the 2 kg trolley after separation = Mass × Velocity = 2 kg × 6 m/s = 12 kg·m/s

d. Given that the total momentum of the trolleys after separation is zero, the momentum of the 3 kg trolley is equal and opposite to the momentum of the 2 kg trolley = -12 kg·m/s

e. The momentum of the 3 kg trolley = Mass of the 3 kg Trolley × Velocity of the 3 kg trolley

∴ The momentum of the 3 kg trolley = 3 kg × Velocity of the 3 kg trolley = -12 kg·m/s

The velocity of the 3 kg trolley = -12 kg·m/s/(3 kg) = -4 m/s

a-The total momentum of the trolleys before separation=0

b.The total momentum of the trolleys after  separation=0

c. The momentum of 2kg trolley after  separation=12kg-m/sec

d. The momentum of 3kg trolley after separation=-12kg-m/sec

e. The velocity of the 3kg trolley=4kg-m/sec

Given-

Trolley A with mass= 2kg

Trolly B with mass= 3kg

Velocity of trolly A =6m/sec

A- Total momentum of the trolleys before separation-

Here, in this problem both the trolleys are in the rest position hence the momentum of both trolleys = 0

B- Total momentum of the trolleys after  separation-

We know that motion never changes in an isolated collection of objects,

hence the momentum of the trolleys before and after the separation=0

C- Momentum of the Trolley A (2kg)-

It is known that momentum= Mass x Velocity

[tex]P=m\times v[/tex]

[tex]P=2\times 6[/tex]

[tex]P=12[/tex]

Hence, the momentum of the 2kg trolley is 12 kg-m/sec

D- Momentum of the Trolley B (3kg)-

As we know that  motion never changes in an isolated collection of an object hence the total moment of after saparation = 0

hance the momentum of the trolley B will be equal and opposite to the momentum of trolley A=

[tex]P= -12[/tex]

Momentum of trolley B (3kg) is -12kg-m/sec

E- The velocity of the 3kg trolley-

The momentum of trolley A= Momentum of trolley B

[tex]m_{b} v_{a} =m_{b} v_{a}[/tex]

[tex]-2\times 6=3\times v_{a}[/tex]

[tex]v_{a}=-4[/tex]

The value of the velocity of the 3kg trolley is -4m/sec

Answer: The lighter object could be pushed up a much steeper incline and for a much longer distance.

Explanation: Using the formula for work, W= F d cosФ, you can see that it takes into account distance and the angle of the incline. With a much larger incline and with much more distance to cover, eventually the lighter object would require more work than a heavier object with no incline and very little distance to cover.

D. 0.276 J

Explanation:

When I solved this, I got 0.275, so I chose the one closest.

To solve:

convert 17 cm and 19.2 cm to 0.17 m and 0.192 m

W(on spring) = 1/2 (0.192 m - 0.17 m)(25N)

                     = 1/2 (.022 m)(25 N)

                     = 0.275

D. 0.276 J

Work is force applied over distance.

Examples of work include lifting an object against the Earth's gravitation, driving a car up a hill, and pulling down a captive helium balloon.

Work is a mechanical form of energy.

The standard unit of work is the joule (J), equivalent to a newton - meter (N · m).

According to the question,

W = Fs

Convert 17 cm and 19.2 cm to 0.17 m and 0.192 m

W = [tex]\frac{1}{2}[/tex](0.192 m - 0.17 m)(25N)

resistance doesn't depend upon the length of the material as the material is same

Answer: A radiator emitting warm air and drawing in cool air.

This is due to the warm air expanding and begins to rise as it is less dense. The cool air begins to "fall" as it is denser, drawing nearer to the radiator. The radiator will then heat the cool air and it will rise. The process then continues

Answer:

Strong Positive Linear Line Correlation

Explanation:

According to the diagram, there is a strong positive linear line correlation between velocity and distance of galaxies. Hubble showed that galaxies are receding away from people with a velocity that is proportional to their distance from people more distant galaxies recede faster than nearby galaxies.

About the diagram: Velocity is the distance relation among extra-galactic nebulae. Radial velocities is corrected for solar motion, are plotted against distances estimated from involved stars and mean luminosities of nebulae in a cluster. The black discs and full line represent the solution for solar motion by using the nebulae individually; the circles and broken line represent the solution combining the nebulae into groups; the cross represents the mean velocity corresponding to the mean distance of 22 nebulae whose distances could not be estimated individually.

Answer:

Q_p = 19575 J

Q_o = 8700 J

Q_g = 78300 J

Explanation:

We are given L0 = 0.5 m

From the image, we can see that;

Length; L = 3L0 = 3 × 0.5 = 1.5 m

Width; W = L0 = 0.5 m

Height; H = 2L0 = 2 × 0.5 = 1 m

Temperature of warmer surface; T_h = 37 ˚C

Temperature of cooler surface; T_l = 8 ˚C

thermal conductivity; k = 300 J/(s·m·C˚)

Time for which the heat flows; t = 3 s

Now, from Fourier's law of conduction, the rate of heat flow is given by;

Q/t = kA(dT/dx)

Where;

A is area

dt is change in temperature = 37 - 8 = 29°C

dx is perpendicular distance

Now, for the amount heat flow perpendicular to the pink surface, from the image dx will be the height 1 m.

Thus;

Q_p/3 = 300 × (1.5 × 0.5) × (29/1)

Q_p/3 = 6525

Q_p = 3 × 6525

Q_p = 19575 J

for the amount heat flow perpendicular to the orange surface, from the image dx will be the length 1.5 m.

Thus;

Q_o/3 = 300 × (1 × 0.5) × (29/1.5)

Q_o/3 = 2900

Q_o = 2900 × 3

Q_o = 8700 J

for the amount heat flow perpendicular to the green surface, from the image dx will be the width 0.5 m.

Thus;

Q_g/3 = 300 × (1 × 1.5) × (29/0.5)

Q_g/3 = 26100

Q_g = 26100 × 3

Q_g = 78300 J

Hi sorry for yesterday

Explanation:

Answer:

485.62 N

Explanation:

To obtain the magnitude of unbalanced forces acting on the body;

Unbalanced Force = Horizontal Component of Applied Force - Frictional Force

Frictional Force = Horizontal Component of  Applied Force - Unbalanced Force

f = frictional force  = ?

F = Applied force  = 593 N

m = mass of person = 49 kg

a = acceleration = 0.57 m/s²

θ = Angle with horizontal = 30°

Hence;

Horizontal Component of  Applied Force = (593 N)(Cos 30°)

Unbalanced Force = (49 kg)(0.57 m/s²)

f = (593 N)(Cos 30°) - (49 kg)(0.57 m/s²)

f = 513.55 N - 27.93 N

f = 485.62 N
