a girl running at 6.72m/s has a momentum of 281kgm/s. what is her mass

The magnitude of the magnetic flux through the loop is 0

The magnitude of the magnetic flux through a loop can be calculated using the formula:

Φ = B * A * cos(θ)

where:

Φ is the magnetic flux,

B is the magnetic field strength,

A is the area of the loop, and

θ is the angle between the magnetic field and the normal to the loop's surface.

In this case, the magnetic field is perpendicular to the plane of the circular loop, so the angle θ between the magnetic field and the normal to the loop's surface is 90 degrees (cos(90) = 0).

Given:

B = 0.60 T (magnetic field strength)

r = 0.40 m (radius of the circular loop)

The area of the loop can be calculated using the formula for the area of a circle:

A = π * r²

Substituting the given values:

A = π * (0.40 m)²

A = 0.16π m²

Now, we can calculate the magnetic flux:

Φ = B * A * cos(θ)

Φ = 0.60 T * 0.16π m² * cos(90)

Φ = 0.60 T * 0.16π m² * 0

Φ = 0

Therefore, the magnitude of the magnetic flux through the loop is 0.

While using a wrench, if you double the length of the wrench, it means that you have halved the required force to do the same amount of work. Hence, option (a) is correct.

The definition of force is an external cause that, when applied, affects or tends to modify the state of the body; if the body is in motion, it will come to rest, and if it is at rest, it will go into motion. It may also result in changes to the body's orientation, form, size, etc. An illustration would be using force to push or pull a door.

In a mixed-tide system, the water levels exhibit two high tides and two low tides within a tidal cycle. The ranking of the water levels according to height is as follows:

Higher high water: This is the highest water level observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun align to produce a stronger tidal bulge. It typically happens around the time of a new moon or a full moon.

Lower high water: This is the second-highest water level observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun are not aligned, resulting in a weaker tidal bulge. It typically happens around the time of the first quarter and third quarter moon phases.

Higher low water: This is the higher of the two low water levels observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun produce a weaker tidal trough. It typically happens between the two high tides.

Lower low water: This is the lowest water level observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun are not aligned, resulting in a stronger tidal trough. It typically happens between the higher low water and the next high tide.

The third piece of the bomb flies off horizontally in the direction opposite to the vector sum of the velocities of the other two pieces.

To determine the direction of motion of the third piece, we need to calculate the vector sum of the velocities of the first two pieces. Let's break down the given velocities into their x and y components.

Piece 1: Velocity = 20 m/s at 60 degrees

Piece 2: Velocity = 12 m/s at 120 degrees

Using trigonometry, we can find the x and y components of the velocities:

Piece 1:

\(V1x = 20 m/s * cos(60) = 10 m/sV1y = 20 m/s * sin(60) = 17.32 m/s\)

Piece 2:

\(V2x = 12 m/s * cos(120) = -6 m/sV2y = 12 m/s * sin(120) = 10.39 m/s\)

Now, we can find the vector sum of the x and y components:

\(Vx = V1x + V2x = 10 m/s + (-6 m/s) = 4 m/sVy = V1y + V2y = 17.32 m/s + 10.39 m/s = 27.71 m/s\)

Finally, we can find the magnitude and direction of the resulting velocity:

\(V = sqrt(Vx^2 + Vy^2) = sqrt((4 m/s)^2 + (27.71 m/s)^2) ≈ 27.99 m/s\)

The direction of motion of the third piece is opposite to this resulting velocity, so it will be approximately 180 degrees.

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

The plane travels a distance of 325 miles if the airplane travels for 2.5 hours at an average speed of 130 miles per hour. Using the distance formula (d = rt), we can calculate the distance.

To find the distance traveled by the airplane, we can use the distance formula, which is represented as d = rt. In this formula, "d" represents the distance, "r" represents the rate or speed at which the object is traveling, and "t" represents the time taken for the travel.

Given that the airplane travels for 2.5 hours at an average rate of 130 miles per hour, we can substitute these values into the formula. The rate of the airplane is 130 miles per hour, and the time taken is 2.5 hours.

Using the formula, we can calculate the distance traveled as follows:

d = rt

d = 130 mph × 2.5 hours

Multiplying the rate (130 mph) by the time (2.5 hours) gives us:

d = 325 miles

3) If it is noon in London, it is 4:00 am in LAX. Your flight takes 10 hours, so it will land in LAX at 2:00 pm (14:00) LAX time.

1. To figure out your longitude when you crash landed on an island in the Pacific Ocean, you need to know the time difference between your watch set to Southern California time and the local time on the island.

The time difference is 4 hours earlier, which means that you are 60 minutes * 4 = 240 minutes (4 hours) behind Pacific Standard Time (PST).

To convert minutes to degrees, you can use the fact that there are 60 minutes in a degree.

Therefore, 240 minutes is equal to 240/60 = 4 degrees west of the PST meridian.

So, your longitude is approximately 118 degrees West (the meridian for Pacific Standard Time is 122 degrees West).

2. There is a 3-hour time difference between Hawaiian Standard Time and Southern California Time.

So, to call your grandma at 8:00 pm Hawaiian Time, you need to call her at 8:00 pm + 3 hours = 11:00 pm Southern California Time.

3. London is 8 hours ahead of LAX (Pacific Standard Time) in terms of time zones.

So, if it is noon in London, it is 4:00 am in LAX. Your flight takes 10 hours, so it will land in LAX at 4:00 am + 10 hours = 2:00 pm (14:00) LAX time.

In an elastic collision, both momentum and kinetic energy are conserved.

Let's denote the 620-g object as object 1 and the 320-g object as object 2.

The initial momenta of the objects are:

 \(p_1 i = m_1 v_1 i\)

       = (0.620 kg)(2.1 m/s)

       = 1.302 kg m/s (to the left)

  \(p_2 i = m_2 v_2 i\)

         = (0.320 kg)(-3.8 m/s)

        = -1.216 kg m/s (to the right)

The total initial momentum of the system is:

\(p_{initial} = p_1 i + p_2 i\)

           = 1.302 kg m/s - 1.216 kg m/s

           = 0.086 kg m/s (to the left)

During the collision, momentum is conserved, so the final momentum of the system is also 0.086 kg m/s to the left.

Let's denote the final velocities of the objects as v₁f and v₂f.

Using the conservation of momentum, we can write:

p₁i + p₂i = p₁f + p₂f

where p₁f = m₁v₁f and p₁f = m₂v₂f.

Since the collision is perfectly elastic, kinetic energy is also conserved. We can write:

\((1/2)m_1v_1i^2 + (1/2)m_2v_2i^2 = (1/2)m_1v_1f^2 + (1/2)m_2v_2f^2\)

Substituting the expressions for p1f and p2f from the momentum equation, we get:

\(m_1v_1i + m_2v_2i = m_1v_1f + m_2v_2f\)

\((1/2)m_1v_1i^2 + (1/2)m_2v_2i^2 = (1/2)m_1v_1f^2 + (1/2)m_2v_2f^2\)

Solving these equations simultaneously, we get:

\(v_1f = (-m_2/m_1)v_2i + (2m_2/m_1)v_1i\)

      = (-0.320 kg/0.620 kg)(3.8 m/s) + (2)(0.320 kg/0.620 kg)(2.1 m/s)

      = -1.87 m/s

\(v_2f = (-m_1/m_2)v_1i + (2m_1/m_2)v_2i\)

       = (-0.620 kg/0.320 kg)(2.1 m/s) + (2)(0.620 kg/0.320 kg)(-3.8 m/s)

       = 5.07 m/s

The final speed of the 620-g object is:

\(|v_1f| = 1.87 m/s\)

The change in kinetic energy of the 620-g object is:

ΔK =\((1/2)m_1v-1f^{2} - (1/2)m_1v_1i^2\)

     = \((1/2)(0.620 kg)(1.87 m/s)^2 - (1/2)(0.620 kg)(2.1 m/s)^2\)

The first three things need to be completed, or at least started, right away: Fly the aircraft as you instantly apply full carb heat and check the gasoline in both or one of the tanks, hit the fuel boost or pump, and mix the fuel to full richness.

Finding the tangent line to the curve y = x2 at that location will help us determine when Han Solo should turn off the engines.

The derivative of the function determines the slope of the tangent line at any point on the curve y = x2.: dy/dx = 2x

Han Solo should turn off the engines at position (x1, y1). Next, we have

y1 = x1^2 (since the point is on the curve y = x^2)

dy/dx = 2x1 (since this is the slope of the tangent line at (x1, y1))

The equation of the tangent line via (4, 15) can be expressed using the point-slope form of a line as follows:

y - y1 = m(x - x1)

Substituting y1 = x1^2 and m = 2x1, we get:

y - x1^2 = 2x1(x - x1)

Now, we can substitute the coordinates of the point (4, 15) to solve for x1:

15 - x1^2 = 2x1(4 - x1)

15 - x1^2 = 8x1 - 2x1^2

x1^2 - 8x1 + 15 = 0

This quadratic equation can be factored as:

A change in temperature frequently causes substances to change phases. Most substances are solid at low temperatures; as the temperature rises, they become liquid; and at still greater temperatures, they become gaseous.

Melting is the conversion of a solid into a liquid (an older term that you may see sometimes is fusion). Solidification is the process where a liquid turns into a solid. The melting point, or the temperature at which a pure substance begins to melt, is a property of that substance. A solid must expend energy to become a liquid. A specific quantity of energy is required by every pure substance in order to transform from a solid to a liquid. This amount is known as the substance's enthalpy of fusion (or heat of fusion).
