Answer:

YEAH MORE OXYGEN BUBBLES THE MORE PHOTOSYNTHESIS OCCURRING

Explanation:

The average velocity over the time intervals (2,3), (2,2.5), (2,2.1), (2,2.01), and (2,2.001) are -53.83 m/s, -1.234 m/s, -19.88 m/s, -49.53 m/s, and -529.3 m/s respectively.

To find the average velocity over a given time interval, we need to find the change in height (displacement) and divide it by the change in time (time interval).

For the time interval (2,3), the displacement is given by h(3) - h(2), which is the difference in height at t = 3 and t = 2. Plugging in the values into the equation for height, we get:

[tex]h(3) - h(2) =[/tex] [tex](53 * 3 - 0.83 * 3^2) - (53 * 2 - 0.83 * 2^2)[/tex]

= 53 - 106.83 = -53.83

The average velocity over the interval (2,3) is given by:

[tex](displacement) / (time interval) = (-53.83) / (3 - 2) = -53.83 m/s[/tex]

For the time interval (2,2.5), the displacement is given by h(2.5) - h(2), which is the difference in height at t = 2.5 and t = 2. Plugging in the values into the equation for height, we get:

[tex]h(2.5) - h(2) = (53 * 2.5 - 0.83 * 2.5^2) - (53 * 2 - 0.83 * 2^2)[/tex]

= 53 - 56.085 = -3.085

The average velocity over the interval (2,2.5) is given by:

[tex](displacement) / (time interval) = (-3.085) / (2.5 - 2) = -1.234 m/s[/tex]

Similarly, for the time intervals (2,2.1), (2,2.01) and (2,2.001), the average velocity can be found using the same method. The smaller the time interval, the closer the average velocity will be to the instantaneous velocity (i.e., the velocity at a specific instant in time) at t = 2.

The SI unit for acceleration is meters per second squared (m/s). Acceleration is the product of the velocity (m/s) divided by the time (s). So, the resulting formula is a = v/t.

Impulse is also known as the change in momentum. Change in momentum is defined as mass times change in velocity (Δp = m · Δv). Change in velocity is equal to acceleration times change in time (Δv = a · Δt).

aA(t) is a linear function and the components of the functions are constant velocity (p) and acceleration (q).

xB(t) is a parabolic function with components constant acceleration (r) and a component for constant jrk (s).

To find the time when the two cars are at the same location, we must first make the two distance expressions equal and then solve for t.

Marie moves her desk to the right, causing friction between the desk and the floor that moves it to "the left." Thus, option C is correct.

The force of friction prevents movement between two surfaces that are in contact with one another. When Marie pushes her desk to the right, friction acts between the desk and the floor in the opposite direction to her push, which is to the left. The direction of friction is determined by the direction of motion between the two surfaces and the direction of the force that opposes this motion.

Friction acts to slow down or stop the motion of an object, so when Marie pushes the desk to the right, friction acts to the left to counteract her push and slow down the motion of the desk.

The correct answer is B. The cylinder reaches the bottom first because it picks up more rotational energy.

The mass of a body is what causes inertia. The inertia of a body increases with its bulk. For instance, a lighter stone can be thrown farther than a smaller one. The heavier object resists change more because it has more mass, or more inertia.

When a sphere and a cylinder of equal mass and radius roll down an inclined plane, the cylinder will pick up more rotational energy due to its larger moment of inertia.

A sphere has a moment of inertia equal to 2/5 of its mass times the square of its radius, while a cylinder has a moment of inertia equal to 1/2 of its mass times the square of its radius.

This means that the cylinder has a larger moment of inertia and will therefore pick up more rotational energy as it rolls down the incline. As a result, it will reach the bottom of the incline before the sphere.

When certain materials are rubbed together, a phenomenon known as "charge" can be transferred from one surface to another. Uncharged items are pulled by charged objects, which in turn may push or pull against other charged ones.

For options

A.) The force that A exerts on B is 10 times the force that B exerts on A.

C.) The force that A exerts on B is 1/10 the force that B exerts on A.

because,

The forces between two charged objects are proportional to the product of the charges and inversely proportional to the square of the distance between the objects. So, the force that A exerts on B is proportional to q * 10q / d^2 and the force that B exerts on A is proportional to 10q * q / d^2, where d is the distance between the two objects.
