Answer:

The net force is 100 N to the right.

Explanation:

To solve this problem, we simply add together the forces.  Since we know that there is a greater force to the right, we will designate this as the positive direction and the left as the negative direction.

To find the net force, let's add together the two forces we are given using our new positive/negative designations:

+150 N right - 50 N left

Now, we just perform simple subtraction to get:

100 N right

Therefore, the answer is that the net force is 100 N to the right.

No, doubling the length of a wire does not necessarily result in cutting the resistance in half. The resistance of a wire depends on several factors, including its length, cross-sectional area, temperature, and the resistivity of the material.

What is Resistance?

Resistance is a measure of how much a material opposes the flow of electric current. It is a fundamental property of electrical circuits and is denoted by the symbol "R". Resistance is typically measured in ohms (Ω), and it determines how much voltage (V) is required to drive a given current (I) through a material or a circuit.

According to Ohm's Law, the resistance (R) of a wire is directly proportional to its length (L) and resistivity (ρ), and inversely proportional to its cross-sectional area (A). Mathematically, this relationship is expressed as:

R = ρ * (L / A)

The force in the rightward direction, fx , should Marcel push is this force leads to counterclockwise torque. Fx = - (w L2 + w L3 - W Lend) / h.

A force in physics is an effect that changes the velocity, or acceleration, of a mass-moving object. It is a vector quantity since it can be a push or a pull and always has magnitude and direction.

Viewing equilibrium of torque:

W Lend + Fx × h = w L2 + wL3

Fx = (w L2 + w L3 - WLend) / h

In the rightward direction, Fx,

Fx = - (w L2 + w L3 - W Lend) / h

Answer:

4 A

Explanation:

From the question given above, the following data were obtained:

Voltage (V) = 12 V

Resistance (R) = 3 Ω

Current (I) =?

From ohm's law,

Voltage (V) = Current (I) × Resistance (R)

V = IR

With the above formula, we can obtain the current flowing in the circuit as illustrated below:

Voltage (V) = 12 V

Resistance (R) = 3 Ω

Current (I) =?

V = IR

12 = I × 3

Divide both side by 3

I = 12/3

I = 4 A

Therefore, the current flowing in the circuit is 4 A.

Answer:

From our investigation of what forces are like in a collision, we learned that when two

objects collide, a force is exerted on each object. The two forces are in opposite

directions but the same strength. This allowed us to infer that an equal strength force

was exerted on the space station and the pod, but in opposite directions.

As a result, the space station and the pod are moving in opposite directions. We need to

learn more about the effects of collisions on each object’s motion so we can report back

to Dr. Gonzales at the space agency.

You will use physical materials to gather data about

forces in a collision. You will also notice how objects

are affected by collisions. Students will use their

data to infer the force direction for objects in a

collision.

Based on the velocity change of each object,

what did you infer about the direction of forces

during a collision?

• We observed that the velocity of each object changed during a collision, so we can infer

that a force had to be exerted on each object. However, the motion of the objects

changed in different ways.

• The object that was moving forward slowed down, so I can infer that the force must have

pushed backward on this object.

• The other object started moving forward, so the force must have pushed forward on that

object. If one force was backward and one force was forward, then the forces pushed

the objects in opposite directions.

Answer:

Fractional calculus is a branch of mathematics that deals with the calculus of functions that are not differentiable at all points. This can be useful for modeling physical processes that involve memory or dissipation, such as viscoelasticity, diffusion, and wave propagation.

Explanation:

Some physical processes that need to use fractional calculation include:

Viscoelasticity: Viscoelasticity is a property of materials that exhibit both viscous and elastic behavior. This can be modeled using fractional calculus, as the fractional derivative of a viscoelastic material can be used to represent the viscous behavior, and the fractional integral can be used to represent the elastic behavior.

Diffusion: Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. This can be modeled using fractional calculus, as the fractional derivative of a diffusing substance can be used to represent the rate of diffusion.

Wave propagation: Wave propagation is the movement of waves through a medium. This can be modeled using fractional calculus, as the fractional derivative of a wave can be used to represent the attenuation of the wave.

Fractional calculus is a powerful tool that can be used to model a wide variety of physical processes. It is a relatively new field of mathematics, but it has already found applications in many areas, including engineering, physics, and chemistry.

Answer:

The given statement is false.

Explanation:

Option c. The speed of light in water compared to the speed of light in a vacuum is slower.

Light refers to electromagnetic radiation of any wavelength, whether it is visible or not. Light is a kind of energy that travels in waves. This implies that light, like other waves, has both frequency and wavelength. A vacuum is a space that is entirely devoid of matter. There is no air, liquid, or solid in a vacuum. The pressure in a vacuum is also zero. A vacuum is a place where the atmosphere's pressure is lower than the atmospheric pressure at sea level.

Speed of light in water compared to the speed of light in vacuum. The speed of light in vacuum is approximately 300,000 kilometers per second (km/s), whereas the speed of light in water is around 225,000 km/s. Light travels slower in water than in a vacuum, which means that the speed of light in water is slower than the speed of light in vacuum. Therefore, option c. slower is the correct answer.

Answer:

Dx/dt  = 4,8 f/s

Explanation:

The ladder placed against a wall, and the ground formed a right triangle

with x and h the legs and L the hypothenuse

Then

L² = x² + h²          (1)

L = 26 f

Taking differentials on both sides of the equation we get

0  = 2x Dx/dt  + 2h Dh/dt    (1)

In this equation

x = 10   distance between the bottom of the ladder and the when we need to find, the rate of the ladder moving away from the wall

Dx/dt is the rate we are looking for

h = ?    The height of the ladder when  x = 10

As    L²  =  x²  + h²

h²  =  L²  -  x²

h²  =  (26)²  - (10)²

h²  =  676  -  100

h²  = 576

h = 24 f

Then equation (1)

0  = 2x Dx/dt  + 2h Dh/dt

2xDx/dt  = -  2h Dh/dt

10 Dx/dt  = - 24 ( -2 )      ( Note the movement of the ladder is downwards)

Dx/dt  =  48/10

Dx/dt  = 4,8 f/s

The water depth just after the hydraulic jump is 0.36 m.

To calculate the water depth just after the hydraulic jump, we can use the conservation of mass principle and the momentum equation.

Given data:

Width of the rectangular channel (B) = 3.2 m

Water depth just upstream before the jump (H1) = 0.72 m

Flow rate (Q) = 13.5 m^3/s

Step 1: Calculate the Froude number before the jump (Fr1)

Fr1 = V1 / sqrt(g * H1)

Where V1 is the velocity before the jump and g is the acceleration due to gravity.

Step 2: Calculate the Froude number after the jump (Fr2)

Fr2 = sqrt(Fr1^2 / 2)

This assumes that the energy loss in the jump is minimal.

Step 3: Calculate the water depth just after the jump (H2)

H2 = H1 / (1 + (Fr1^2 - 1) / 2)

This equation is derived from the specific energy equation.

Substituting the given values, we can calculate the Froude numbers and the water depth just after the jump.

Therefore, the water depth just after the hydraulic jump is 0.36 m.

The third quartile is 183.72 minutes. So, the answer is 183.72 minutes.

Given: The typical college freshman spends an average of =150 minutes per day, with a standard deviation of =50 minutes, on social media and the third quartile is 0.75.

Therefore, we can determine the answer as follows:

We know that the third quartile, denoted by Q3, is the value such that 75% of the data lies below it. So, z-score corresponding to the third quartile is given by:

z = invNorm(0.75)

Where, invNorm is the inverse Normal distribution function.

By definition, the inverse Normal distribution gives the z-score given the area under the Normal distribution curve. Here, we need to find the area corresponding to the upper tail of 0.25 (since 75% of the data lies below the third quartile). This can be calculated as follows:

Area to the left of Q3 = 1 - Area to the right of Q3= 1 - 0.25 = 0.75

Therefore, the z-score corresponding to this area is given by:

z = invNorm(0.75) = 0.6745

Now, the value of the third quartile can be obtained by using the z-score formula as follows:

z = (X - μ) / σ

where, X = value of the third quartile, μ = population mean = 150 (given), σ = population standard deviation = 50 (given)

Substituting the values, we get:

0.6745 = (X - 150) / 50

Solving for X, we get: X = 150 + 0.6745 * 50X = 183.72

Therefore, the third quartile is 183.72 minutes. So, the answer is 183.72 minutes.
