Explanation:

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.

The conditions required for total internal reflection (TIR) to occur are:

1)the light must be travelling from a more dense medium into a less dense medium (ie glass to air)

2)the angle of incidence must be greater than the critical angle.

Condensed water droplets collect other water droplets to form the collector drop until they fall from the clouds as rain. In this way rain is formed in the tropics where the air is warmer.

A significant volume of water evaporates and is released into the atmosphere when water bodies are heated during the day. Evaporation is the term for this. Water vapour is carried upward by the hot air as it rises. The air cools and expands as it rises. Condensation is the term for this occurrence. Clouds are created as a result of water vapour condensation. With the assistance of the wind, these clouds are transported away, and when they become heavy, they drop to the ground as rain.

The property of a transverse wave that stays the same even as the wave's energy and other properties change is the wavelength.

The correct option to the given question is option a.

The wavelength is the distance between two successive points of the wave that are in phase. As the wave's energy and amplitude change, the distance between two successive points of the wave that are in phase remains the same.

This is because wavelength is determined by the frequency of the wave and the speed of propagation. The frequency of the wave is the number of cycles of the wave that occur in one second, while the speed of propagation is the rate at which the wave travels through a medium.

If the frequency of the wave and the speed of propagation remain the same, then the wavelength will also remain the same even as the wave's energy and other properties change. This property is known as the characteristic of the wave.The amplitude is the maximum displacement of a point on the wave from its rest position. The frequency is the number of cycles of the wave that occur in one second. The rest position is the position of the medium when it is not disturbed.

Hence, wavelength of a transverse wave remains same even as the wave's energy and other properties change.

Answer:

a. 0.947 m/s^2

b. 1304.54 N

c. 0.0966

Explanation:

mass of car = 13500 N = 13500/9.8 = 1377.55 kg

velocity = 50 km/h = 50,000 m/h = 13.9 m/s

raidus = 204 m

a. centripetal acceleartion = v^2/r = 13.9^2/204 = 0.947 m/s^2

b. centripetal force = m*centripetal acceleration = 1377.55 * 0.947 = 1304.54 N

c. In order for the car to round the curve safely, static friction = centripetal force

static friction = coefficient of friction (mu) * mg = mu* 1377.55*9.8 = 13500mu

13500mu = 1304.54

mu = 1304.54/13500 = 0.0966

The acceleration, force and coefficient of friction is required.

Centripetal acceleration is \(0.965\ \text{m/s}^2\)

Centripetal force is \(1328\ \text{N}\)

Coefficient of friction is \(0.1\)

N = Weight of car = 13500 N

v = Velocity = \(50=\dfrac{50}{3.6}=13.89\ \text{m/s}\)

r = Radius = \(2\times 10^2\ \text{m}\)

m = Mass of car = \(\dfrac{N}{g}\)

g = Acceleration due to gravity = \(9.81\ \text{m/s}^2\)

Centripetal acceleration is

\(a_c=\dfrac{v^2}{r}\\\Rightarrow a_c=\dfrac{13.89^2}{2\times 10^2}\\\Rightarrow a_c=0.965\ \text{m/s}^2\)

Force is given by

\(F_c=ma_c\\\Rightarrow F_c=\dfrac{N}{g}a_c\\\Rightarrow F_c=\dfrac{13500}{9.81}\times 0.965\\\Rightarrow F_c=1328\ \text{N}\)

Coefficient of friction is given by

\(\mu=\dfrac{F_c}{N}\\\Rightarrow \mu=\dfrac{1328}{13500}\\\Rightarrow \mu=0.098\approx 0.1\)

Explanation:

Answer: inertia

Explanation:

The magnitude of the force of the branch on the toothpick was 38.8 N.

To find the magnitude of the force of the branch on the toothpick, we can use the formula F = ma where F is the force, m is the mass and a is the acceleration.

Force can be defined as the product of mass and acceleration. We know the mass of the toothpick and we can calculate the acceleration from the change in velocity and the penetration depth.

Since the toothpick's speed was decreased at a uniform rate, the acceleration is given by a = 2d/t², where d is the penetration depth and t is the time taken for the toothpick to stop.

We are given that the mass of the toothpick is 0.15 g, its speed before entering the branch was 175 m/s, and its penetration depth was 11 mm.

Converting the mass to kg, we get 0.00015 kg.

Converting the penetration depth to meters, we get 0.011 m.

The time taken for the toothpick to stop can be found using the equation v = u + at, where u is the initial velocity, v is the final velocity (0), a is the acceleration and t is the time taken.

Rearranging this equation, we get t = u/a.Substituting the given values, we get t = 0.000875 s.

Therefore, the acceleration is a = 2d/t² = 345.7 m/s². Finally, using F = ma, we get F = 0.00015 kg × 345.7 m/s² = 0.0519 N. Rounding this to two significant figures, we get the magnitude of the force of the branch on the toothpick as 38.8 N.

The radius of the cylinder is approximately 2.19 m, and the cylinder is experiencing a deceleration of approximately 1.86 m/s². Since the cylinder is decelerating and the force applied is less than the friction force, it is not slipping.

From the given information:

Mass of the cylinder, m = 5 kg

Moment of inertia of the cylinder, I = 12 kg·m²

Diameter of the cylinder, D = 0.5 m

Force applied, F = 25 N

Coefficient of friction, μ = 0.7

Radius of the cylinder, r = ?

To determine the radius (r) of the cylinder, we can use the relationship between moment of inertia (I) and mass (m) for a solid cylinder:

I = (1/2) * m * r²

Given I = 12 kg·m² and m = 5 kg, we can solve for r:

12 = (1/2) * 5 * r²

r² = 12 / (1/2) * 5

r² = 12 / 2.5

r² = 4.8

r ≈ √4.8

r ≈ 2.19 m

So, the radius of the cylinder is approximately 2.19 m.

Now, let's determine the acceleration of the cylinder. The force applied is given as F = 25 N. The friction force can be calculated using the equation:

Friction force = μ * Normal force

Since the cylinder is being pulled by the string, the normal force is equal to the weight of the cylinder, which is given by:

Weight = mass * acceleration due to gravity

Weight = m * g

Assuming a standard acceleration due to gravity of 9.8 m/s²:

Weight = 5 kg * 9.8 m/s² = 49 N

Friction force = μ * Normal force = μ * Weight = 0.7 * 49 N = 34.3 N

Now, we can calculate the net force acting on the cylinder:

Net force = Force applied - Friction force

Net force = 25 N - 34.3 N

Net force = -9.3 N

Since the net force is negative, indicating that the force applied is less than the friction force, the cylinder will experience a deceleration rather than acceleration. The magnitude of the deceleration can be calculated using Newton's second law:

Net force = mass * acceleration

-9.3 N = 5 kg * acceleration

acceleration = -9.3 N / 5 kg

acceleration = -1.86 m/s²

The negative sign indicates that the deceleration is in the opposite direction to the force applied, which means the cylinder is moving in the direction opposite to the applied force.

Hence, the radius of the cylinder is approximately 2.19 m, and the cylinder is experiencing a deceleration of approximately 1.86 m/s². Since the cylinder is decelerating and the force applied is less than the friction force, it is not slipping.

When a neuron is in the resting potential state, the neuron is negatively charged on the inside and positively charged on the outside.

When a neuron is not actively responding to an electrical input, which is commonly accepted to be when it is in its resting state, there is widespread consensus that the neuron is in its resting state. The charge on the neuron's inner membrane is now higher than the charge on the neuron's outer membrane. Because of the selective permeability of the cell membrane, the various ion concentrations on either side of the membrane are unable to get balanced with one another.

When the membrane is in its resting state, it is permeable to the passage of potassium ions (K⁺). In the same way as chloride (Cl⁻) ions find it difficult to move through a resting state, sodium (Na⁺) ions also find it difficult to do so. There is a membrane that stops negatively charged proteins with an anion difference of one (A⁻) from passing into neighboring neurons.

A pump is also present in the neuronal cell membrane, and this pump requires energy in order to remove three ions of sodium for every two ions of potassium that enter the cell. A neuron's resting potential can be defined as the voltage difference that exists between the neuron's interior and its outside in the absence of any external influences.

Explanation:

So, we have a negative test charge that is experiencing a force to the right as a result of an electric field. What can we conclude from this description?

Well, we know that negative charges experience a force that is opposite to the direction of the electric field. In this case, the negative test charge is experiencing a force to the right, which means that the electric field is pointing to the left.

Therefore, the best conclusion to draw from this description is: "The electric field points to the left because the force on a negative charge is opposite to the direction of the field."

It's important to note that no conclusion can be drawn about the amount of charge on the test charge because that information is not given. However, we can still confidently conclude that the electric field points to the left based on the direction of the force on the negative test charge.
