The 80.50 dollars would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 32.0 mi/gal.

To convert a given amount expressed in terms of unit miles to unit kilometres, use the miles to km formula. There are 1.6 kilometres in a mile.

The currency and monetary unit of the European Union is the euro, denoted by the sign €. Prior to being released as currency notes and coins in 2002, it started out as a noncash monetary unit in 1999. The national currencies of participating EU members and certain non-EU states were replaced by the euro.

Calculation:

Total km so 113km per day for 7 days is 791 km.

Then we change 791km to miles = 491.211 miles.

Since the car is 32 miles per gallon we divide 491.211/32= 15.35 gallons.

We change gallons to liters so we have 15.35gal x 3.785L= 58.09 L

At 1.10 euros per liter is 58.09 x 1.10 = 63.89 euros.

Correct Answer 100%! Pls, give me brainliest. Thank You!

Answer:

Alice Distance = 100 meters

Peter's Distance = 3 km

Alice Displacement and Peter's displacement are both 100 meters upwards.

Explanation:

To solve this question, we have to first define distance and displacement.

Distance is simply the measurement of the sum of all paths travelled from one point to another while displacement is measurement of the shortest distance from initial point to final point.

Now, Alice and Peter are moving from the same point.

Alice distance travelled is 100 meters.

Also, her displacement will be 100 meters because it is the shortest distance to the summit of the cliff.

Now, for Peter, he decides to take a longer route which is 3 km in distance.

However, the shortest path which is the displacement is still 100 meters.

Thus, Peter's displacement is 100 meters.

Sediment production occurs primarily in the upper part of a river system.

In this region, the river has a higher gradient and more energy, which leads to increased erosion and weathering of the surrounding landscape. As the river flows, it picks up sediments such as sand and clay from the eroded materials. These sediments can come from various sources, including rocks, soils, and organic matter.

The process of sediment production is influenced by factors such as precipitation, vegetation, and land use. For example, heavy rainfall can result in increased erosion, while vegetation can help stabilize soil and reduce sediment production. Additionally, human activities such as agriculture, construction, and deforestation can alter the landscape and contribute to increased sedimentation in river systems.

As the river moves downstream, its gradient decreases, and it loses energy, causing the sediments to be deposited. Understanding sediment production and transport in river systems is essential for managing water resources, predicting flood risks, and conserving aquatic habitats.

Answer: 24

Explanation: because my brain said..

F b = (m * v) / t is the formula for the amount of average net force needed to reach a specific velocity.

Average speed is determined by dividing the total distance you travelled by the total time, whereas average velocity is determined by dividing your displacement (a vector pointing from your initial position to your end position) by the whole time.

The following formula can be used to determine the average net force, F b, necessary to reach a specific velocity, v:

F_b = (m * v) / t

Its net force, which is inversely related to its mass, is:

a = F_net / m

The final velocity can be related to the acceleration and time using the following kinematic equation because the fist's velocity is attained from rest:

v = a * t

When we enter the acceleration expression from Newton's second law into this equation, we obtain:

v = (F_net / m) * t

To solve for the net force by rearranging this equation, we obtain:

(a)The critical value for a 95% confidence level is approximately 1.96. (b) A higher confidence level requires a wider interval to capture the true population mean with greater certainty.

(a) To construct a 95% two-sided confidence interval on the mean life of the light bulbs, we can use the formula:

CI = X ± z × (σ ÷√n)

where X is the sample mean, σ is the population standard deviation, n is the sample size, and z is the critical value corresponding to the desired confidence level.

In this case, X= 1014 hours, σ = 25 hours, and n = 20. The critical value for a 95% confidence level can be found using a standard normal distribution table or a calculator. For a two-sided confidence interval, we divide the desired confidence level by 2 and find the corresponding z-value.

The critical value for a 95% confidence level is approximately 1.96. Substituting the values into the formula, we have:

CI = 1014 ± 1.96 × (25 ÷ √20)

the confidence interval on the mean life.

(b) To construct a 95% lower-confidence bound on the mean life, we can use the formula:

Lower bound = X - z × (σ ÷ √n)

Using the same values as in part (a), the lower bound can be calculated.

The lower bound from part (a) is the lower confidence bound for the mean life.

For the second part of the question, we have two confidence intervals: (38.02, 61.98) and (39.95, 60.05).

Applying 100 lbs. of force to 1 sq. in of area creates a fluid pressure. To determine the fluid pressure, we need to convert the force into the appropriate unit and divide it by the area.

Fluid pressure is calculated by dividing the force applied by the area over which the force is distributed. In this case, the force is given in pounds (lbs) and the area is given in square inches (sq. in). To ensure consistent units, it is necessary to convert pounds to a unit of force such as newtons (N) and square inches to a unit of area such as square meters (sq. m).

To convert pounds to newtons, we use the conversion factor: 1 lb = 4.44822 N. Therefore, the force of 100 lbs can be converted to approximately 444.822 N.

To convert square inches to square meters, we use the conversion factor: 1 sq. in = 0.00064516 sq. m. Thus, the area of 1 sq. in is equivalent to approximately 0.00064516 sq. m.

Now, we can calculate the fluid pressure by dividing the force (in newtons) by the area (in square meters): Fluid Pressure = Force / Area = 444.822 N / 0.00064516 sq. m. This yields the value of fluid pressure created by applying 100 lbs. of force to 1 sq. in of area.

Answer:

Total momentum = 50kgm/s

Explanation:

Given the following data;

Mass, M1 = 5kg

Mass, M2 = 7kg

Velocity, V1 = 10m/s

Velocity, V2 = 0m/s (since it's at rest).

To find the total momentum;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

\( Momentum = Mass * Velocity \)

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

Total momentum = M1V1 + M2V2

Substituting into the equation, we have;

Total momentum = 5*10 + 7*0

Total momentum = 50 + 0

Total momentum = 50 kgm/s

Therefore, the total momentum of the bowling ball and the putty after they collide is 50 kgm/s.

The correct answer is **c. As a planet falls closer to the Sun, the force of attraction increases, speeding up the planet**.

Kepler's Second Law states that a planet sweeps out equal areas in equal times as it orbits the Sun. This means that the planet moves faster when it is closer to the Sun and slower when it is farther away.

In the context of Newtonian gravity, the force of gravity between the Sun and the planet is inversely proportional to the square of the distance between them. As the planet falls closer to the Sun, the distance decreases, resulting in a stronger gravitational force. According to Newton's second law of motion, F = ma (force equals mass times acceleration), the increase in force causes an acceleration of the planet. Consequently, the planet moves faster as it falls closer to the Sun.

Therefore, the correct explanation for Kepler's Second Law, based on Newtonian gravity, is that as a planet falls closer to the Sun, the force of attraction increases, speeding up the planet.

According to the law of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision.

Let's assume the mass of the receiver is denoted as "m" (in kg).

Before the collision:

Momentum of the tackler (p1) = mass of the tackler (m1) * velocity of the tackler (v1)

Momentum of the receiver (p2) = mass of the receiver (m) * velocity of the receiver (0, as the receiver is standing still)

After the collision:

Total momentum = momentum of the tackler + momentum of the receiver

The total momentum after the collision is:

Total momentum = (mass of the tackler + mass of the receiver) * velocity after the collision (3 m/s)

Since momentum is conserved, we can equate the total momentum before and after the collision:

p1 + p2 = (m1 * v1) + (m * 0) = (m1 * v1) = (m1 + m) * 3

Simplifying the equation, we get:

m1 * v1 = m1 * 3 + m * 3

m1 * v1 = 3 * (m1 + m)

Now we can substitute the given values into the equation. Given:

m1 = 100 kg

v1 = 4.0 m/s

Substituting the values, we have:

100 * 4.0 = 3 * (100 + m)

Simplifying the equation:

400 = 300 + 3m

3m = 100

m = 100 / 3 ≈ 33.33 kg

Therefore, the mass of the receiver is approximately 33.33 kg.

Explanation:

A force of 40 N pushing an 80-N crate up a 30° incline for a distance of 5.0 m does 200 J of work and increases the crate's kinetic energy by

90J.

To find the work done by the force, we can use the work-energy principle, which states that the net work done on an object is equal to its change in kinetic energy. In this case, the crate is initially at rest, so its initial kinetic energy is zero.

The force pushing the crate is parallel to the slope, so we can use trigonometry to find its component force along the slope:

F_parallel = F * sin(30°) = (80 N) * sin(30°) = 40 N

The work done by the force is given by:

W = F_parallel * d = (40 N) * (5.0 m) = 200 J

The speed of the crate increases at a rate of 1.5 m/s², so its final kinetic energy is:

Kf = (1/2) * m * vf² = (1/2) * (80 N) * (1.5 m/s)² = 90 J

The change in kinetic energy is therefore:

ΔK = Kf - Ki = 90 J - 0 J = 90 J

Since the net work done on the crate is equal to its change in kinetic energy, we have:

W = ΔK = 90 J

Therefore, the work done by the force is 200 J.

Explanation:

The question is incomplete, as there are no diagrams or options to provide more information to the question.

The general explanation is as follows:

For the object not to move

(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).

(2) The two forces must be equal.

So, for instance:

If the pair of forces are 5N and 5N in opposite directions, the object wil not move.

However, if one of the forces is greater, the object will move towards the direction of the greater force.

Option b. is correct.

An electron is confined in a 1-dimensional box of length L. If the length of the box is decreased to L/2, the energy levels of the electron would...decrease.

Explanation: In a 1-Dimensional box, the energy of an electron is determined by the formula: E= h²n²/8mL²Where h is Planck's constant, m is the mass of the electron, L is the length of the box, and n is the quantum number. The energy levels of the electron would decrease when the length of the box is suddenly decreased to L/2.

This happens because the energy levels depend on the length of the box and when the length is decreased, the energy levels decrease too. The formula shows that energy levels are inversely proportional to the square of the length of the box. This means that when the length is decreased to half of its original value, the energy levels decrease to a quarter of their original value. Therefore, the energy levels of the electron decrease when the length of the box is suddenly decreased to L/2.
