Answer: Cells have receptors because Receptors let the cell know when to let things in and out of the cell.

Explanation:

Cell receptors also called transmembrane receptors are proteins located on the surface of a cell (extracellularly) or inside the cell which receive signals that alters the functions of the cell. The functions of the cells which can be altered includes the alteration in gene transcription and the cell morphology.

Cell receptors are generally categorizes into the following groups:

--> Internal receptors

--> cell surface receptors

--> ion channel receptors

--> G protein coupled receptors

--> enzyme linked receptors

Interaction of cell membrane receptors with specific ligands that bonds to the receptors causes conformational changes in the receptor protein. This in turn, enzymatically activates the intracellular part of the protein or induces interactions between the receptor and the proteins in the cytoplasm that act as second messengers, thereby relaying the signal from the extracellular part of the receptor to the interior of the cell. This enables the cell to know when to let things in or out of it through the information conveyed.

Answer:

The momentum, ΔP, and therefore, kinetic energy given to the ball in a serve is the result of the product of the tension force, 'F', in the string and the time of contact, Δt, between the ball and the string

ΔP = F × Δt

Explanation:

The impulse, ΔP, is the produce of the force, 'F', applied to a body for a given period of time, Δt', that gives motion to the body, and it is equal to the change of momentum of the body

ΔP = F × Δt

The momentum, 'P', of a body is the product of the mass, 'm', of the body and its velocity, 'v'

P = m × v

Tension is the axial pulling force of a string

T = Axial Force, F\(_{axial}\)

The tension used in Tennis Racket strings is between 40 to 65 lbs.

When high tension is used in the string, the string is taut, and the contact duration between the Racket string and the ball is minimal, and the player needs to use more force to obtain a high momentum, and therefore, energy in the ball, which reduces control, and increase stress, as force is more emphasized

When low tension is used in the string, the Tennis Racket strings are more elastic. During a serve, the ball pushes the strings further back into the racket, such that the ball spends more time in contact with the string, (Δt is larger), and therefore, the impulse, F·Δt = ΔP, given to the ball is larger, therefore, the ball has a larger change in momentum, and therefore more energy in the intended direction.

However, a very slackened string will increase the increase area and time (large Δt) of contact of the ball and the racket such that the force given to the ball, F = ΔP/(large Δt) is reduced and therefore reduce the likelihood of gaining points from a serve against an opponent with a much forceful return of a serve.

Length of the solenoid, l = 50.0 cm = 0.50 mA = 0.385 m²µ₀ = 4π x 10⁻⁷ H/m. L = (µ₀N²A)/lL = [4π x 10⁻⁷ H/m × (100)² × 0.385 m²]/0.50 mL = 7.87 x 10⁻⁴ H.  The induced emf in the solenoid when t=20.0 s is -4.13 V

a) Find the self-inductance of the solenoid.

A solenoid is a type of electromagnet, the wire coiled up such that it produces a magnetic field when electric current passes through it.

The self-inductance of the solenoid can be given by the formula:  

 L= (µ₀N²A)/

lwhere  µ₀ is the permeability of free space

N is the number of turns of the solenoid

l is the length of the solenoid

A is the cross-sectional area of the solenoid

Given that, Number of turns, N = 100

Length of the solenoid, l = 50.0 cm = 0.50 mA = 0.385 m²µ₀ = 4π x 10⁻⁷ H/m. L = (µ₀N²A)/lL = [4π x 10⁻⁷ H/m × (100)² × 0.385 m²]/0.50 mL = 7.87 x 10⁻⁴ H.

b) Find the induced emf in the solenoid when t = 20.0 s.

The induced emf (ε) can be calculated by the formula;

ε = -L dI/dt

where L is the self-inductance of the solenoid and dI/dt is the time rate of change of the current given by;    

I(t)=(5.00A)e^t/2.00s

Differentiating I(t) with respect to t gives;   dI/dt = 5e^t/2  V/s (Volts per second)Given that L = 7.87 x 10⁻⁴ HWhen t = 20.0s;  ε = - L dI/dt  = -7.87 × 10⁻⁴ H × (5e^20/2)  = -4.13 V

Therefore, the induced emf in the solenoid when t=20.0 s is -4.13 V.

At the bottom of the hill, the roller coaster will be going 15.96 m/s. At the top of the hill, the roller coaster has potential energy (PE) equal to its mass (m) times the acceleration due to gravity (g) times its height (h).

As it moves down the hill, this potential energy is converted into kinetic energy (KE), which is equal to one half its mass times its velocity squared.

Using the law of conservation of energy, we can set the potential energy at the top of the hill equal to the kinetic energy at the bottom of the hill and solve for the velocity.

PE = mgh = KE = (1/2)mv^2

Rearranging the equation to solve for v gives us:

v = sqrt(2gh)

Plugging in the given values for g (9.8 m/s^2) and h (13 m) gives us:

v = sqrt(2 * 9.8 * 13)

v = sqrt(254.8)

786.2m/s²

Explanation:

Given parameters:

Force  = 114N

Mass  = 0.145kg

Unknown:

Acceleration of the baseball  = ?

Solution:

According to newton's second law of motion, the product of mass and acceleration is the net force on the body;

   Force  = mass x acceleration

Insert the parameters and find the acceleration;

    114  = 0.145 x acceleration

   Acceleration  = \(\frac{114}{0.145}\) = 786.2m/s²

The correct answer 13 N.

Force causes an object to come to rest when it accelerates and causes a body to accelerate when it is at rest. Force is therefore the result of mass times acceleration. The overall force applied on a body is known as the net force. The total of all forces exerted on an object is known as the net force. There are two different types of forces: balanced forces and imbalanced forces. The term "balanced force" refers to an object that is balanced on both of its sides. Unbalanced force is defined as the movement of an item caused by an excessive force applied to one side.

Force exerted by Kam = 5N

Force exerted by Jaylan = 8N

Thus the net force = 5N + 8N

                                = 13 N

the ranking that is correct if no heat is lost to the environment through the sides of the copper rod would be point A > point B > point C.

The ranking that is correct if no heat is lost to the environment through the sides of the copper rod would be point A > point B > point C. Therefore, the correct option is option B.

Heat transfer is the process of the thermal exchange of energy from one point to another.

In heat transfer, heat energy is transferred from hotter objects to colder objects until they reach the same temperature. Heat transfer can take place through three main ways which are convection, conduction, and radiation.

A uniform copper rod is a good conductor of heat and the temperature is spread evenly across the rod. In the question given, the rod is sitting with one end in a boiling beaker of water and the other end in a beaker of ice water. The heat flows along the rod from the hot end to the cold end of the rod and the heat energy is transferred by conduction.

When the copper rod is placed with one end in a boiling beaker of water, the end of the copper rod will have the highest temperature and will be point A. The point where the rod enters the beaker of ice water will be point C, which is at a lower temperature than point A. The point at which the copper rod is halfway between the boiling beaker and the beaker of ice water will be point B. It is important to note that no heat is lost to the environment through the sides of the copper rod.

Therefore, the ranking that is correct if no heat is lost to the environment through the sides of the copper rod would be point A > point B > point C.

A circular steel wire 2.00 m long must stretch no more than 0.25 cm when a tensile force of 700 n is applied to each end of the wire. The minimum diameter that is required for the wire is 1.50 × 10⁴ m.

The formula that would help solve the problem is:

ΔL = FL/ (πd²E × 4)

Where;ΔL = 0.25 cm=0.0025 m, F = 700N, l = 2.00 m, d = ?, E = 2.0 × 10¹¹Pa

For wire, E = Young’s modulus, and d = diameter.

Substituting values into the formula;

0.0025m = 700N × 2.00m/(πd² × 2.0 × 10¹¹Pa × 4)

0.0025m = 1400/(πd² × 8 × 10¹¹)

0.0025m = 0.00001745/d²

2.25 × 10⁸ = d²

d = √(2.25 × 10⁸) = 1.50 × 10⁴ m

The electron would have to move at a speed of approximately 7.15 x 10^5 m/s to have a de Broglie wavelength of 4.50 mm.

The de Broglie wavelength of a particle is given by λ = h/p, where h is Planck's constant and p is the momentum of the particle. The momentum of an electron is given by p = mv, where m is the mass of the electron and v is its velocity. By substituting these equations, we get λ = h/mv. Solving for v, we get v = h/(mλ). Substituting the values, we get v = (6.626 x 10^-34 J s)/[(9.11 x 10^-31 kg)(4.50 x 10^-6 m)] = 7.15 x 10^5 m/s.

if the mass of a body were doubled, its gravity would become 4 times stronger, False If the mass of a body were doubled.

Its gravity would only become twice as strong, not four times stronger. The strength of gravity is directly proportional to the mass of the object, but it is not a linear relationship. It follows the inverse square law, which means that doubling the mass only results in a doubling of the gravitational force.

The force of gravity between two objects depends on their masses and the distance between them, and it is given by the equation:

F = G × (m1 × m2) / r²

where F is the force of gravity, G is the gravitational constant, m1, and m2 are the masses of the two objects, and r is the distance between them.

If the mass of one of the objects is doubled, then the force of gravity between the two objects would increase, but it would not become 4 times stronger. Instead, it would become 2 times stronger. This can be seen by plugging the new mass into the equation and comparing it to the original force:

F' = G × (2m × m) / r²

F' = 4 × (G × (m ×m) / r²)

So the new force, F', is twice the original force, not four times.

Therefore, the statement "if the mass of a body were doubled, its gravity would become 4 times stronger" is false.
