The goalie slides on the ice with a velocity of 0.24 m/s

One of physics' most powerful laws is the conservation of momentum. The law of momentum conservation is explained in the paragraphs that follow.

For an impact between object 1 and object 2, the combined momentum of the two objects prior to the collision is equal to the combined momentum of the two after the collision.

Final momentum equals initial momentum

75 kg at 0 m/s and 0.105 kg at 24 m/s equals 0.105 kg at v and 75 kg at v.

where v represents the goalie's final velocity.

calculating v:

(0.0105 kg + 75 kg)  v = 24 kg m/s

v = 0.105 kg + 75 kg / 24 kg m/s

v = 0.24 m/s

As a result, the goalie slides on the ice at a 0.24 m/s speed.

Explanation:

The best method for producing a plant similar to the one you already have will depend on the specific plant and the desired outcome. Here are some common methods of plant propagation:

Seeds: This is the most traditional and natural method of propagating plants. The seeds can be collected from the parent plant, or purchased from a reputable source, and then planted in soil or another growing medium.

Cuttings: Cuttings are pieces of stem or leaf taken from the parent plant and used to grow a new plant. This method is often used for plants that are difficult to propagate from seeds, or for plants that have special qualities (such as a particular color or texture) that the grower wants to preserve.

Layering: This is a method in which a stem is bent to the ground and rooted in soil, while still attached to the parent plant. The rooted stem can then be separated from the parent plant and grown as a new plant.

Grafting: Grafting involves taking a cutting from one plant (the scion) and joining it to the rootstock of another plant. This allows the grower to combine the desirable qualities of both plants into a single plant.

Tissue Culture: Tissue culture involves taking a small piece of tissue from the parent plant and growing it in a sterile, nutrient-rich environment. This method is often used for plants that are difficult to propagate through other means, and can also be used to produce a large number of identical plants.

The best method will depend on the specific requirements of the plant and the desired outcome. Some plants may respond better to one method over others, so it's important to do some research and choose the method that is best suited for your plant.

The athlete's average density is 1.06 kg/L.

From the question, we're given this information:

The buoyant force is 690 - 38 = 652 N

We can calculate the mass of water that is displaced using the formula
  F = m * g

  m of water displaced = 652 / 9.8 = 66.53 kg

Assuming a water density is the usual 1 kg/L, we can use the formula
  V = mass / density

  V of water displaced = 66.53 / 1 = 66.53 L

Therefore, the V of athlete is also 66.53 L

Then, we can calculate the athlete's mass using F = m * g

  690 = m * 9.8

  m = 690 / 9.8 = 70.41 kg

From here, since we already know the athlete's mass and volume, we can calculate her average density

The required work done in lifting the bucket and the water is W = 424.736 J.

The work done in lifting the bucket and the water can be calculated as:

W = [tex]m_{bucket}[/tex] * g * h + [tex]m_{water}[/tex] * g * h

where m_bucket is the mass of the bucket, m_water is the initial mass of water in the bucket, g is the acceleration due to gravity (9.8 m/s^2), and h is the height lifted (16 m).

However, since the water is leaking, the mass of water decreases over time. The final mass of water can be calculated as m_water = m_initial - kt, where k is the constant rate of leakage and t is the time taken to lift the bucket.

W = [tex]m_{bucket}[/tex] * g * h + ([tex]m_{initial}[/tex] - kt) * g * h

W = (m_bucket + [tex]m_{initial}[/tex] - kt) * g * h

W = (10 + 48 - k * h / g) * 9.8 * 16

Since the water finishes draining just as the bucket reaches the 16-m level, we know that k * h / g = 48, so k = 48 * g / h = 48 * 9.8 / 16 = 30.06 kg/s.

Finally, the work done can be calculated as:

W = (10 + 48 - 30.06 * 16 / 9.8) * 9.8 * 16

W = 10 * 9.8 * 16 + 48 * 9.8 * 16 - 30.06 * 16 * 9.8

W = 158.4 + 754.4 - 488.064

W = 424.736 J

So the work done in lifting the 10-kg bucket with 48 kg of water to a height of 16 m at a constant speed with a rope that weighs 0.7 kg/m is 424.736 J.

Explanation:

(a) The magnitude of the force on each charge = 5.05 x 10⁶ N

(b) Directions of the force = along the line between the charge and the center of the square outward of the center (option 4)

Units of mass times length over time squared are used to express the strength of a force. The most used unit in metric measurements is the newton (N), which is equal to one kilogram times one meter over one second squared. This means that an item weighing one kilogram would accelerate at a rate of one meter per second squared in response to a one newton force. The pound (lb), which is the most widely used unit in English, is equal to one slug times a foot over a second squared. This means that an item having a mass of one slug would accelerate at a velocity of one foot per second squared in response to a one pound force.

Use the equation:

F net = 2 F cos(45) + F1

= 2cos(45) k q²/a²+ k q²/d²

Where,

q = the charge= 8.65 mC

d = diagonal= √2 (0.240) = 0.339

F is the force due to adjacent particle

This is due to the fact that an electron has a negative charge and will be drawn to areas of lower potential, whereas a proton has a positive charge and will be drawn to areas of higher potential. Because it has no charge and is neutral, a neutron is unaffected by the electric field.

The English physicist J.J. Thomson made the discovery of the electron in 1897 while researching cathode rays. His discovery of electrons—originally referred to as corpuscles—revolutionized our understanding of atomic structure.

You ride your bike along a straight road for a distance d at a constant speed. The constant speed during the second part of the trip was 28.6 mi/hr.

Let's call the constant speed during the second part of the trip v. To find v, we need to use the equation for average speed:

Average speed = Total distance / Total time

We know the average speed for the entire trip and the distance traveled during the second part of the trip, so we can write:

13.0 mi/hr = (d + 2d) / Total time

13.0 mi/hr = 3d / Total time

We also know the time it took to travel the first part of the trip, which was at a constant speed of 11.0 mi/hr:

Time for first part = d / 11.0 mi/hr

So, the total time for the entire trip is:

Total time = d / 11.0 mi/hr + 2d / v

We can substitute the expression for average speed and the value of d we found earlier into this equation:

13.0 mi/hr = 3d / (d / 11.0 mi/hr + 2d / v)

13.0 mi/hr * (d / 11.0 mi/hr + 2d / v) = 3d

13.0 mi/hr * d / 11.0 mi/hr + 13.0 mi/hr * 2d / v = 3d

13.0 * d + 26.0 * 2d / v = 33.0 * d / 11.0

26.0 / v = 33.0 / 11.0 - 13.0

26.0 / v = 10.0 / 11.0

v = 26.0 / (10.0 / 11.0) = 26.0 * 11.0 / 10.0 = 28.6 mi/hr

So the constant speed during the second part of the trip was 28.6 mi/hr.
