A.
She could really injure herself with this plan since she will not feel pain.
B.
Trying it once or twice and seeing how she feels is probably the best way to go.
C.

What is ankle sprain?

A sprain takes place when your ankle is compelled to move out of its regular place, causing one or more of the ligaments in your ankle to stretch, partially tear, or completely tear.

A sprained ankle can be caused by a fall that causes your ankle to twist. Landing on your foot awkwardly after jumping or pivoting.

You should avoid strenuous exercises, such as running, until the pain and swelling have subsided, but you should keep moving so that the muscles and ankle do not stiffen. Once your ankle is less painful, begin some gentle exercises.

As she is having ankle sprain, and she is planning to take pain killers and start to work out, this can cause her even more problem as she will not feel any pain.

Thus, the correct option is A.

Three forces act simultaneously on poin J. One force is 10.0 N north; the second is 15.0 N west; the third is 15.0 N 30.0° east of north. Determine the magnitude and direction of the resultant force.​

Answers

The magnitude and direction of the resultant force are 10.0N and 101.36⁰

The sum of force along the force horizontal is expressed as:

[tex]\sum F_x=-15.0N+15cos30\\\sum F_x = -15.0N + 12.99N\\\sum F_x = -2.01N[/tex]

The sum of force along the vertical is expressed as:

[tex]\sum F_y = +10N[/tex]

Calculate the magnitude of the force:

[tex]F=\sqrt{(\sum F_x)^2+(\sum F_y)^2} \\F=\sqrt{(-2.01)^2+(10)^2} \\F=\sqrt{104.0401}\\F= 10.2N[/tex]

Hence the magnitude of the resultant force is 10.2N

Find the direction

[tex]\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{10}{-2.01}\\\theta =tan^{-1}(-4.9751)\\\theta =-78.63^0\\\theta = 180-78.63 = 101.36^0[/tex]

As shown above an adhesive has been applied to contacting faces of two blocks so that the blocks interact with an adhesive force that has a magnitude, Fadhesion A tension, T, is exerted by a wire attached to the upper blocks causing the blocks to remain at rest The two blocks have weights, Wbottom and Wtop. Which of the following must be true? (1 point) ♡ O Wtop=T OT = Wtop - Fadhesion O Wbottom Fadhesion O T = Wbottom + Wtop + Fadhesion​

Answers

The magnitude of the adhesive force allows the top block to remain

attached to the bottom when the blocks and the wire are balanced.

The option that must be true is; [tex]\mathbf{W_{bottom} = F_{adhesion}}[/tex]

Reason:

The tension exerted by the wire attached to the top block = T

Magnitude of the adhesive = [tex]F_{adhesion}[/tex]

Weight of the top block = [tex]W_{top}[/tex]

Weight of the bottom block = [tex]W_{bottom}[/tex]

Given that with the exertion of the tension, the two blocks remain at rest, we have;

T =  [tex]W_{top}[/tex] + [tex]W_{bottom}[/tex]

The adhesive causes the bottom block to remain attached to the top block, we have;

Therefore, the magnitude of the adhesive force adds the bottom weight, to the top, weight, which gives;

The magnitude of the adhesive force = The weight of the bottom block

Therefore;

Explanation:

A diver runs toward the edge of the cliff in Tobermory. This cliff is 44 m high (top of cliff to water level). They dive out, horizontally, at a velocity of 1.8 m/s [forward]. The sign below was posted for a reason. There is a section of rock right under the rough water extending from the cliff out for 4 m, as shown below. Does the diver hit the hidden rocks?

Answers

This question involves the concepts of the equations of motion for both the vertical motion and the horizontal motion.

The diver "does not" hit the rock.

First, we will calculate the time taken by the diver to land. For this purpose, we will use the second equation of motion for the vertical motion of the diver:

[tex]h = v_{iy}t+\frac{1}{2}gt^2[/tex]

where,

h = height of cliff = 44 m

[tex]v_{iy}[/tex] = vertical component of the initial velocity of the diver = 0 m/s

t = time taken to land = ?

g = acceleration due to gravity = 9.81 m/s²

Therefore,

[tex]44\ m=(0\ m/s)t+\frac{1}{2}(9.81\ m/s^2)(t)^2\\\\t = \sqrt{\frac{(44\ m)(2)}{9.81\ m/s^2}}[/tex]

t = 3 s

Now, we will calculate the horizontal distance where the diver landed. For this purpose, we will use the equation of motion for the horizontal motion of the diver. Assuming the air resistance to be zero the horizontal motion will be uniform. Hence:

[tex]s = vt\\s = (1.8\ m/s)(3\ s)\\[/tex]

s = 5.4 m

Since the section of the rock was 4 m away from the cliff. Hence, the diver crossed that rock section and safely laded at a distance of 5.4 m, which is 1.4 m ahead of the rock section.

Answers

Answer:

-Increase in temperature: increase

-Decrease in temperature: decrease

-Increase in volume: increase

-Decrease in volume: decrease

-Increase in pressure: increase

-Decrease in pressure: decrease

Explanation:

-Increase in temperature:

● Molecules gain kinetic energy and move fast thus increasing distance

-Decrease in temperature:

● Kinetic energy of molecules decrease so they have smaller distance

-Increase in volume:

● Molecules have more space to move around so distance increase

-Decrease in volume:

● Less space, molecules collide with each other because of decreased distance thus increasing pressure

-Increase in pressure

● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance

-Decrease in pressure:

● Molecules collide with each other and walls of container less frequently so distance between molecules decrease

The answer is: C - both answers above are correct.

Explanation:

The SI base units for newtons is: kg x m/s ².

When separated it is basically: the amount of force that one kilogram multiplied by one meter per second squared (this is the acceleration)

One Newton can be defined as the amount of force that would give a mass of one kilogram an acceleration of one meter per second per second.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. Newton is the SI unit of force.

From Newton's second law of motion: we know that:

Force = mass × acceleration

Now in SI system:

Unit of force is Newton.

Unit of mass is kg and unit of acceleration is meter per square second.

Hence, one Newton force can be defined as:

Hi there!

Recall that:

∑F = ma

In the given situation, there is acceleration occurring in the horizontal direction, so there is a net force.

∑F = Fa (Force applied) - Fκ (Force due to kinetic friction)

We can plug in given values to solve for the frictional force:

ma = Fa - Fκ

(4)(1) = 8 - Fκ

4 = 8 - Fk

Fκ= 4N (negative since working opposite to acceleration)

Now, solve given the new force:

4a = 12

When you describe a liquid as thick, are you saying that it has a high or a low viscosity?

Answers

It is commonly perceived as "thickness", or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity.

The liquid with greater thickness will be more viscous since it flow speed is lower. Therefore, the more thick liquids is more viscous and flow slowly.

What is viscosity ?

Viscosity of a liquid is the resistance to its flow. Viscosity depends on the density and thickness of the liquid. The more thicker the liquid the more viscous it will be.

Less thick liquids will flow fastly. For example water is a less viscous liquid as we see it flow so quickly. Whereas, honey, oil, etc are more viscous and the mobility of their liquid particles are resisted by viscosity.

The more viscous liquids generally has higher specific heat capacity as in the case of water and oil. The particle - particle attractive force is higher in highly viscous liquids.
