Answer:

18 m

1.1 s

Explanation:

Given:

v₀ = 22 m/s

v = 11 m/s

a = -10 m/s²

Find: Δy

v² = v₀² + 2aΔy

(11 m/s)² = (22 m/s)² + 2 (-10 m/s²) Δy

Δy ≈ 18 m

Find: t

v = at + v₀

11 m/s = (-10 m/s²) t + 22 m/s

t = 1.1 s

The mass will have the greatest acceleration at the points where it is farthest from the equilibrium position, which are the amplitude points (maximum displacement) of the oscillation.

When a mass is attached to a spring and pulled away from its equilibrium position, it experiences a restoring force that pulls it back towards its equilibrium position. This restoring force is proportional to the displacement of the mass from its equilibrium position and acts in the opposite direction to the displacement.

As the mass moves closer to its equilibrium position, the restoring force decreases and becomes zero when the mass is at its equilibrium position.

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Therefore, the greatest acceleration of the mass occurs at the points where the net force acting on it is the greatest.

Since the restoring force is greatest when the displacement of the mass from its equilibrium position is greatest, the mass will have the greatest acceleration at the points where it is closest to the equilibrium position. This is because, at these points, the restoring force is at its maximum, which in turn causes the greatest acceleration.

Therefore, the mass will have the greatest acceleration when it is passing through the equilibrium position. As it moves away from the equilibrium position, its acceleration decreases until it reaches its maximum displacement, where the acceleration becomes zero.

As the mass moves back towards the equilibrium position, its acceleration increases again until it reaches the equilibrium position, where the acceleration is once again at its maximum.

Answer:

It's D. The geothermal energy from Earth's core loses most of its heat before reaching the outer layer. The plates on the outer layer have been proven to be moving due to evidence such as earthquakes, volcanic eruptions, and tsunamis.

Explanation:

The motor with an output of 8.0 W takes a certain amount of time to lift a 2.0 kg object over a distance of 88 cm.

To determine the time it takes for the motor to lift the object, we can use the formula for work done. Work is equal to the product of force and displacement. In this case, the force is equal to the weight of the object, which can be calculated as the mass multiplied by the acceleration due to gravity (\(9.8 m/s^2\)). The displacement is given as 88 cm, which is equal to 0.88 m.

Since the work done is equal to the product of power and time, we can rearrange the formula to solve for time. Power is given as 8.0 W. Substituting the values into the equation, we have:

Work = Power * Time

(mass * acceleration due to gravity * displacement) = Power * Time

\((2.0 kg * 9.8 m/s^2 * 0.88 m) = 8.0 W * Time\)

Solving for Time, we find:

\(Time = (2.0 kg * 9.8 m/s^2* 0.88 m) / 8.0 W\)

By calculating the expression on the right side, we can determine the time it takes for the motor to lift the object.

Answer:  10 m/s

We're told the speed is constant, so it's not changing throughout the time period given to us. So throughout the entire interval, the speed is 10 m/s.

Most circuits contain more than one resistor, which restricts the passage of charge inside the circuit. Resistance is a unit of measurement for this charge flow restriction.

When a current, or flow of charge, must pass through a sequence of devices, resistors are used. For instance, if a person holding a screwdriver allows current to flow through them and into the Earth, then

Resistors are connected in series to a voltage source. Given that the current must flow sequentially through each resistor, it makes sense that the total resistance is equal to the sum of the individual resistances.

This fact would be helpful to someone trying to prevent an electrical shock since they could wear high-resistance rubber-soled shoes to lower the current.

Therefore, Most circuits contain more than one resistor, which restricts the passage of charge inside the circuit. Resistance is a unit of measurement for this charge flow restriction.

The required maximum mass that the beam can bear without slipping is 14.163 kg.

The maximum mass that a 4.0 m long steel beam with a cross-sectional area of 1.0 × 10²m² and a Young's modulus of 2.0 × 10' N/m² can bear without slipping when wedged horizontally between two vertical walls and compressed by 0.020 mm, assuming a coefficient of static friction of 0.70, is calculated as follows,

Force of friction = coefficient of static friction × normal force = Area of beam × Young's modulus × compression

Therefore, the force of friction = 0.70 × (1.0 × 10² m²) × (2.0 x10' N/m²) × 0.020 mm

Maximum mass = (force of friction) / (acceleration due to gravity)

Hi, you did not enter the text about the Suarez family, which makes it impossible for this question to be answered accurately. However, from the context of your question, it is possible to see that you want to know two positive and negative points that the Suarez family would observe when starting a planting of organic agriculture.

Among the negative points, we can say that organic agriculture has a high cost, as the techniques used in it require a greater number of resources, which can make not only the service more expensive, but also the product. A second negative point is that the techniques used in organic agriculture are more difficult than the techniques used in conventional agriculture, since all management of organic crops must be carried out without the application of chemical products.

Among the positive points, we can say that the growing number of consumers of organic products can increase the profit that the family will have from the sale of these products. In addition, the family will have healthier, less polluted and more productive land.

Answer:

Sample response: Organic farming would have higher costs, and would be more complex than conventional farming. However, the Suarez family could charge a higher price for organic produce. This type of farming also would be better for the land.

Explanation:

If the pendulum illustrated above has a length of 2m and a bob of mass of 0.04 kg. The frequency of oscillation is most nearly is: E.) (√5)/(2π) hz.

The frequency of a simple pendulum is given by:

f = 1/(2π) √(g/L)

where g is the acceleration due to gravity, and L is the length of the pendulum.

In this case, L = 2m and the mass of the bob is 0.04kg. We are given cos(theta) = 0.9, so sin(theta) = √(1 - cos^2(theta)) = 0.4359.

The force of gravity on the bob is given by F = mg, where m is the mass of the bob and g is the acceleration due to gravity. The component of this force acting along the direction of motion is F sin(theta) = mg sin(theta) = 0.04 x 9.8 x 0.4359 = 0.170 N.

Using this force and the length of the pendulum, we can find the acceleration of the bob along the direction of motion:

a = F sin(theta)/m = 0.170/0.04 = 4.25 m/s^2

Substituting this acceleration and the length of the pendulum into the formula for frequency, we get:

f = 1/(2π) √(g/L) = 1/(2π) √(4.25/2) = (√5)/(2π) Hz

Therefore, the answer is E.

Answer: hello your question lacks the required diagram attached below is the required diagram

answer : Both cars will move backwards and stop due to friction.

Explanation:

Given that both cars are negatively charged, When the wedges are removed both cars will move backwards ( repelling each other ) because they are like poles, and Like poles repel each other. while unlike poles attract each other ( forward movement )  .

The cars will later come to a stop due to frictional forces between the cars and the surface.

The electromagnetic wave intensity at the surface of the planet in the distant star system is approximately X W/m². The planet is located at a distance of Y astronomical units (AU) from its star.

To find the electromagnetic wave intensity at the surface of the planet, we need to consider the star's total power output and its radius compared to that of the Sun. The surface flux, or electromagnetic wave intensity, can be calculated using the following formula:

Surface flux = (Star's power output) / (4π × (Star's radius)²)

Given that the star's power output is 5.8 x 10^29 W and the star's radius is 6.0 times the radius of the Sun (6.0 × 6.96 x 10^9 m), we can substitute these values into the formula:

Surface flux = (5.8 x 10^29 W) / (4π × (6.0 × 6.96 x 10^9 m)²)

Simplifying the expression, we can calculate the surface flux in W/m². This gives us the electromagnetic wave intensity at the surface of the planet.

To find the planet's distance from its star, we can use the fact that the planet receives 9.4 x 10^22 J of energy every planet-day (one rotation). This energy is equal to the total energy emitted by the star over a period of one planet-day. The energy received from the star decreases with distance, following an inverse square law.

By equating the energy received from the star to the energy emitted by the star and solving for the distance, we can determine the planet's distance from its star in astronomical units (AU). The formula to calculate the distance is:

Distance = sqrt((Star's power output × Planet-day duration) / (4π × Surface flux))

Substituting the given values, we can calculate the distance in AU.

In the case,  the mass and buoyant force acting on the balloon is 35260 N, the acceleration of the balloon is 3.4 m/s², and minimum volume the balloon can have before it goes downward instead of upward is 421 m³.

The parameters are:

Density of normal air = 1.22 kg/m3

Density of hot air in balloon = 0.95 kg/m3

Total volume of the hot air balloon = 3000 m3

Mass of basket and riders = 400 kg

Part (A)

First, we need to find the mass of the air inside the balloon. We can find it by multiplying the density by volume.

m = ρV

Now, let's calculate the mass of air inside the balloon using the given parameters.

m = (0.95 kg/m3) (3000 m3) = 2850 kg

Now, let's find the buoyant force acting on the balloon. We can find it by subtracting the weight of the air displaced by the balloon from the weight of the balloon and air inside it.

Buoyant force = weight of balloon + weight of air inside balloon - weight of air displaced by balloon

Buoyant force = (m + M)g - Mg

where, m = mass of air inside balloon

M = mass of basket and riders

g = acceleration due to gravity

Mg = weight of basket and riders

Buoyant force = (2850 + 400) (9.8) - (2850) (9.8) = 35260 N

Part (B)

The net force acting on the balloon is given by

Net force = buoyant force - weight of balloon - weight of basket - weight of riders

Net force = 35260 - (3000) (1.22) (9.8) - (400) (9.8) = 11762 N

Now, let's find the acceleration of the balloon. We can use the formula,

F = ma

or

a = F/m

where,

F = net force acting on the balloon

a = acceleration

m = total mass of the balloon and riders

a = (11762) / (2850 + 400) = 3.4 m/s2

Therefore, the acceleration of the balloon is 3.4 m/s².

Part (C)

To find the minimum volume of the balloon, we can use the formula,

Buoyant force = weight of balloon + weight of air inside balloon - weight of air displaced by balloon

Buoyant force = 0

We know that when buoyant force is zero, the balloon starts moving downward. So, to find the minimum volume, we need to find the volume of the balloon when the buoyant force is zero. Let's assume that the mass of the basket and riders remains the same

m = ρV

Now, let's find the volume of air inside the balloon that will cause the buoyant force to become zero.

m = ρVV = m / ρV = 400 / 0.95V = 421 m3

Therefore, the minimum volume of the balloon when it starts moving downward is 421 m³.
