What is the instantaneous velocity of B?

What is the instantaneous acceleration at F?

Answer:

This question will be answered based on general photosynthetic understanding. The answer is:

The production of oxygen would increase

Explanation:

The characteristics of most plant forms is their ability to photosynthesize i.e. use solar energy (from sunlight) to make food (chemical energy). The product of this photosynthetic process is OXYGEN gas, which is released as a waste product via the stomata on their leaves. Note that, photosynthesis cannot occur without LIGHT as it provides the energy needed for the process.

Hence, in the duckweed plant like every other photosynthetic plant, the increase in the intensity and duration of exposure to light means the rate at which photosynthesis occurs will be increased. An increased photosynthetic rate means the synthesis of the products will also be increased i.e. glucose and OXYGEN.

Answer:the car is speeding up

Explanation:

Answer:

A. 25 m/s

B. 100 m/s (i'm not sure about this one)

Explanation:

A. To find average velocity:  velocity = distance / time

So it would be V = 500 m / 20 sec = 25 m/s

*This equation can only be used if you are finding velocity for a constant speed or direction or specific distance (in this case it was specific distance).

B.  final velocity = initial velocity + acceleration * time

Initial velocity (5.0 m/s) and time (20 sec) is given but not acceleration.

To find acceleration: a = (final velocity - initial velocity) / time

To find final velocity = 5.0 + a * 20

Since there's a missing variable for both equation we will plug the final velocity equation into the acceleration equation so it looks like this :

a = ((5.0 + a * 2.0) - 5.0) / 20  

Now solve to get a (acceleration)

Acceleration ends up being 0. So now that we know acceleration we can solve for the final velocity.

final velocity = 5.0 + 0 * 20

= 100 m/s

I know it's a lot but I hope that makes sense! Also for B. I'm not sure if it's right at all but if later I figure out it's wrong I'll edit my answer.  

Answer:  The difference between velocity and acceleration is that velocity is the current speed while acceleration is the increase in speed.

Answer:

I THINK option A is correct

Explanation:

because the electrostatic force is directly proportional to product of charges

now if the force between two electron is F charge on electron is same so their product is positive now the charge on proton is +ve and on electron is -ve so their product is -F

Answer:

Vf = 4.77 m/s

Explanation:

During the downward motion we can easily find the final velocity or the velocity with which the ball hits the ground, by using third equation of motion. The third equation of motion is given as follows:

2gh = Vf² - Vi²

where,

g = acceleration due to gravity = 9.8 m/s²

h = height = 1.16 m

Vf = Final Velocity of Ball = ?

Vi = Initial Velocity of Ball = 0 m/s (Since, ball was initially at rest)

Therefore, using these values in the equation, we get:

(2)(9.8 m/s²)(1.16 m) = Vf² - (0 m/s)²

Vf = √(22.736 m²/s²)

Vf = 4.77 m/s

Answer:

Change in velocity

Explanation:

a-p-e-x

Acceleration measures the rate of change of velocity with respect to time. It describes how quickly an object's velocity is changing over time. Acceleration can be positive, negative, or zero. The standard unit for acceleration in the International System of Units (SI) is meters per second squared (m/s²).

Mathematically, acceleration (a) is defined as the change in velocity (Δv) divided by the change in time (Δt):

a = Δv / Δt

Acceleration has both magnitude (how much the velocity changes) and direction. When an object's velocity increases, its acceleration is positive. When the velocity decreases, the acceleration is negative.

The standard unit for acceleration in the International System of Units (SI) is meters per second squared (m/s²), which represents how many meters per second the velocity changes in one second.

However, other units like miles per hour squared (mi/h²) or kilometers per hour squared (km/h²) can also be used depending on the context.

Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

Explanation:

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

Answer:

a) Frequency is inversely proportional to the wavelength, then the graphs with smaller wavelengths than A have larger frequency than A.

The correct options are: B and C.

b) The opposite as above, in this case the correct options are: D and E.

c) The ones with the same wavelength will have the same pitch:

A and F seems to have the same wavelength.

B and C also seems to have the same wavelength.

d) The vertical height of the peaks are related to the louder sounds, then the sounds louder than A are: B and F.

e) The one that has a higher pitch (or smaller wavelength) and the same amplitude than A is C.

(you need to measure the height of the peaks in both graphs, and see that are equal).

f) D has a larger wavelength than A, so it would sound "lower", and both waves have the same amplitude, so the loudness will be the same.

Explanation:

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (63 m/s − 25 m/s) / (17 s − 6 s)

a ≈ 3.45 m/s²

Scientific model of volcanic eruptions using computer programming is very helpful to identify their origin and consequences. The biggest benefit of these model is to identify the physical behaviors of magma .

Scientific model are used to visualize the complex theories and concepts. There are both theoretical models and visual models. Nowadays complex problems and processes are easily solving using well designed computer programmes and simulations.

By creating a sophisticated computer model based on the most recent physical understanding of magma behavior, its most likely path of least resistance, and statistical information obtained from prior volcanic  eruptions, scientists was able to address these issues.

They were able to predict the site of historical events that were not used to fine-tune the model by using historical data collected from Campi Flegrei, a caldera close to Naples, Italy etc.
