The overall function of the calvin cycle is __________.

Answers

The overall function of the calvin cycle is to produce sugars (glucose).

CALVIN CYCLE:

  • The Calvin cycle is the second stage of photosynthesis that occurs in the stoma of the chloroplast organelle.

  • The Calvin cycle uses the products of the first stage called light stage (ATP and NADPH) to produce sugar molecules.

  • Calvin cycle also recovers the raw materials needed for the process to continue in a cyclical manner.

  • However, overall function of the calvincycle is to produce sugars(glucose).

A 0.40-kg cart with charge 4.0 x 10-5 C starts at rest on a horizontal frictionless surface 0.50 m from a fixed object with charge 2.0 x 10-4 C. When the cart is released, it moves away from the fixed object. (a) How fast is the cart moving when very far (infinity) from the fixed charge

Answers

Answer:

26.82m/s

Explanation:

Given

Mass = m= 0.4kg

Initial Velocity = u = 0

Charge = 4.0E-5C

Distance= d = 0.5m

Object Charge = 2E-4C

First, we'll calculate the initial energy (E)

E = Potential Energy

PE = kQq / d

Where k = coulomb constant = 8.99E9Nm²/C²

Energy is then calculated by;

PE = 8.99E9 * 4E-5 * 2E-4 / 0.5

PE = 143.84J

Energy = Potential Energy = Kinetic Energy

K.E = ½mv² = 143.84J

½mv² = ½ * 0.40 * v² = 143.85

0.2v² = 143.85

v² = 143.85/0.2

v² = 719.25

v = √719.25

v = 26.81883666380777

v = 26.82m/s

Hence, the object is 26.82m/s fast when the cart moving is very far (infinity) from the fixed charge

according to newton's second law of motion of the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration?

Answers

Answer:

The Acceleration will increase

Explanation:

Newton's Second Law of motion: It states that the rate of change of momentum is directly proportional to the applied force and takes places along the direction of the force.

It can be expressed mathematically as,

F ∝ m(v-u)/t

Where (v-u)/t = a

F  = kma.

F = force, m = mass of the body, a = acceleration, k = constant of proportionality which tend to unity for a unit force, a unit mass, and a unit acceleration.

Therefore,

F = ma.

From the equation above,

If the net force acting on a body increase, while the mass of the body remains constant, the acceleration will also increase.

250j of chemical energy are stored in the battery. calculate how many joules of kinetic energy will the electric car

Answers

Answer:

To calculate how many joules of kinetic energy an electric car can have using the 250 joules of stored chemical energy from the battery, you'll need to consider the efficiency of the energy conversion from chemical to kinetic energy. Electric cars are not 100% efficient in converting stored energy to kinetic energy due to losses in the system, including in the motor, transmission, and drivetrain.

Let's say the efficiency of the conversion is "η," where η is a value between 0 and 1 (e.g., 0.85 for 85% efficiency). The kinetic energy (KE) the car can have will be:

KE = η * 250 joules

You can calculate the kinetic energy for different efficiency values by substituting η into the formula.

For example, if the efficiency is 85%:

KE = 0.85 * 250 joules = 212.5 joules

So, with an 85% efficiency, the electric car can have approximately 212.5 joules of kinetic energy from the 250 joules of stored chemical energy in the battery. The actual efficiency may vary depending on the specific car and its components.
