Explanation:

The coefficient of friction between the soap and the floor is 0.081

If Juan steps on the soap with a force of 493 N, this is her weight, W. This weight also equals the normal reaction on the floor, N.

We know that frictional force F = μN where μ = coefficient of friction between soap and floor.

So, μ = F/N

Since F = 40 N and N = W = 493 N,

μ = F/N

μ = 40 N/493 N

μ = 0.081

So, the coefficient of friction between the soap and the floor is 0.081

Answer:

I guess it is the reason

Explanation:

A dam is thicker at the bottom than at the top because the forces exerted are strongest close to the ground. Water pressure increases proportionally with depth, so the lower portion of the dam has greater water pressure exerted upon it. The increasing thickness of the lower dam also helps it support its own weight.

This is because of Pressure.

Pressure is directly proportional to depth and the deeper the length the high the pressure. Thus at the bottom, water pressure is very high and the walls must be made thicker to accommodate that pressure.

Answer:

Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

Explanation:

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. ... They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.

Velocity:

Velocity is change in displacement with respect to time:

[tex]\frac{\Delta x}{\Delta t}[/tex]

Analysing the units, meters (displacement) and seconds (time) are basic units:

[tex]\frac{m}{s}[/tex]

Therefore the unit of velocity is m/s

Force:

Newton's second law of motion:

[tex]F = ma[/tex]

Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:

[tex]a=\frac{\Delta v}{\Delta t}[/tex]

Analysing the units:

[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]

Therefore, the unit of force is:

[tex]kg\frac{m}{s^2}[/tex]

Pressure:

Pressure is given by the equation:

[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force

Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:

[tex][l^2]=m^2[/tex], the unit of area

Dividing the aforementioned unit of force by the unit of area:

[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure

Work:

Work is given by the equation:

[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)

Knowing displacement's (x) unit is m:

[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.

Explanation:

Answer:

It isn't A.

Explanation:

I got it wrong with the answer A.

it is harder to swim in water with a current (like the ocean) than in contained water (like a pool) because Still water is an immovable object, but currents have their own momentum. The correct option is D.

Newton's first law of motion, also known as the law of inertia, states that "an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force."

This means that an object will continue to move in a straight line at a constant speed unless an unbalanced force acts upon it. In addition, if an object is at rest, it will remain at rest unless acted upon by an unbalanced force.

The law of inertia can be applied to many situations. For example, if a book is sitting on a table, it will remain at rest until a force is applied to it. Similarly, if a ball is rolling on a flat surface, it will continue to roll at a constant speed in a straight line unless a force, such as friction, slows it down or changes its direction.

This law is fundamental to understanding the behavior of objects in motion, and it forms the basis for the other two laws of motion formulated by Sir Isaac Newton.

Here in the Question,

Swimming in a pool versus swimming in the ocean, the difference lies in the presence of a current in the ocean.

The current in the ocean has its own momentum, and when a swimmer enters the water, they are faced with an additional force that they must overcome to move forward. This means that the swimmer must apply more force and use more energy to overcome the force of the current and move forward in the water.

In still water, on the other hand, there is no external force acting on the swimmer, so they only have to overcome the resistance of the water itself to move forward.

Therefore, The correct answer is D i.e Still water is an immovable object, but currents have their own momentum.

Explanation:

Statement of the given problem,

A truck of mass 10000 kg is moving through a sloppy road of length 20 km with the help of 5000 N force. If the truck climb the vertical height of 200 m and its efficiency is 80% calculate the additional mass that can be carried by the truck?

Let M denotes the additional mass (in kg) that can be carried by the truck.

From above data we determine that,

P.E. gained by total mass at the vertical height of 200 m = 80% of work done by the applied force [road elevation = tan^-1 (200/20000) = 0.57° (assumed negligible)]

Hence we get following relation,

(10000 + M)*g*200 = 5000*20*1000*80/100 [g = gravitational acceleration]

or 10000 + M = 50000*8/g = 50000*8/10 [g = 10 m/s^2 (assumed)]

or M = 40000 - 10000 = 30000 (kg) [Ans]

Answer:

Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.

Our Earth is a rotating planet. Fast moving air is deflected by the Coriolis effect, except exactly on the equator. This defines the direction of cyclones, hurricanes, and typhoons rotation. The wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.

The high is west of you, and the low is east of you. (If you're in the northern Hemisphere.)

Traveled north = 18 blocks

Traveled east = 10 blocks

Traveled south = 16 blocks

So total distance = (18+10+16) blocks = 44 blocks

as north and south are opposite

so traveled displacement from up to down is = (18-16) blocks = 2 blocks

and starting to east distance is 10 blocks

so using pythagoras theorem the displacement

C. She is not releasing the endorphins that she used to, and that impacts her sleep.

Explanation:

The best explanation for why Therese is having trouble sleeping is that she is not releasing the endorphins that she used to, and that impacts her sleep.

Hence, the correct option is C.

Endorphins are hormones that are released during exercise. They have mood-boosting and pain-relieving effects. When Therese stops exercising, she is no longer releasing as many endorphins, which can lead to moodiness and difficulty sleeping.

Option A is incorrect because exercise does not directly move oxygen through the blood. Instead, it increases the heart rate and breathing rate, which in turn increases the amount of oxygen that is delivered to the tissues.

Option B is incorrect because there is no evidence to suggest that Therese requires more exercise than most people to relieve stress. In fact, most people find that regular exercise can help to reduce stress levels.

Option D is incorrect because it is unlikely that Therese is not maintaining the healthy habits that she did when she was practicing. Lacrosse is a physically demanding sport, so it is likely that Therese is still eating healthy and getting enough sleep.

Therefore, the best explanation for why Therese is having trouble sleeping is that she is not releasing the endorphins that she used to, and that impacts her sleep.

Hence, the correct option is C.

Considering the definitipn of current, voltage, power, and Ohm's law,

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.

The conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.

This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.

The resistance that is measured in ohms.

Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically, Watt's law is expressed:

[tex]I=\frac{V}{R}[/tex]

So if you want to find resistance, the expression for its calculation is:

[tex]R=\frac{V}{I}[/tex]

In this case, you know:

Replacing:

[tex]R=\frac{5.26 V}{0.41 A}[/tex]
