Why is the direction of position V upwards?

Answers

Answer:

The wave is moving from left to right (as indicated by the arrow), so, given that at the current instance the amplitude of the position V is 0 (or whatever midpoint the dashed line corresponds to), in the immediately next instance the position will continue increasing as the wave moves from left to right. The peak currently shown at U will at some point "arrive" at V. At that point the location V will have the maximum amplitude. After that the direction at position will be downward, etc.

What force is needed to keeps 20kg box moving at a constant velocity when the mk is 0.3021 and the force is applied level to the ground

Answers

Answer:

59.2 N

Explanation:

According to Newton's second law, the resultant of the forces acting on the box must be equal to the product between the box's mass and its acceleration:

[tex]F_{net}=ma[/tex]

However, the box is moving at constant velocity, so its acceleration is zero:

a = 0

Therefore, the net force along the direction of motion (parallel to the surface) must be zero.

We have two forces acting along the direction parallel to the ground:

- The applied force, F

- The frictional force, [tex]\mu mg[/tex], in the opposite direction, with [tex]\mu = 0.3021[/tex] being the coefficient of friction, m = 20 kg the mass of the box and g = 9.8 m/s^2

Therefore, the equation of motion becomes:

[tex]F-\mu mg=0[/tex]

And solving for F, we find:

[tex]F=\mu mg=(0.3021)(20 kg)(9.8 m/s^2)=59.2 N[/tex]

A 49 N box is to be pulled up a 10 degree ramp at an angle of 40 degrees to the ramp that is 5 m long. The box starts at the base of the ramp. Of the coef of Kinetic friction is 0.1, how hard do you have to pull to make the box to move up the ramp at a constant velocity?

Answers

Answer:

17.4 N

Explanation:

According to Newton's second law, the net force acting on the box along the ramp is equal to the product of mass and acceleration:

[tex]F_{net}=ma[/tex]

If we want to move the box at constant velocity, this means acceleration equal to zero: a = 0, so the previous equation becomes:

[tex]F_{net}=0[/tex] (1)

Let's now understand what are the forces exerted on the box along the surface of the ramp:

- The pull (the applied force), let's call it F, which pulls up along the ramp. However, this pull is applied at an angle of 40 degrees, so the actual pull along the ramp will be [tex]F cos 40^{\circ}[/tex]

- The component of the weight parallel to the surface of the ramp, equal to

[tex]-mg sin \theta[/tex]

where (mg) = 49 N is the weight of the box and [tex]\theta=10^{\circ}[/tex] is the angle of the ramp. This force pulls down along the ramp, so we put a negative sign in front of it.

- The frictional force, equals to

[tex]-\mu mg cos \theta[/tex]

where [tex]\mu=0.1[/tex] is the coefficient of friction. This force pulls down along the ramp (in the opposite direction of the motion), so we put a negative sign as well

Therefore, the equation for the net force (1) becomes:

[tex]F cos 40^{\circ}-mg sin \theta -\mu mg cos \theta =0[/tex]

from which we can find the value of F:

[tex]F=\frac{mg sin \theta + \mu mg cos \theta}{cos 40^{\circ}}=\frac{(49 N)(sin 10^{\circ})+(0.1)(49 N)(cos 10^{\circ})}{cos 40^{\circ}}=17.4 N[/tex]

Which free body diagram shows the forces acting on block A?




Answers

Answer:

The 3rd graph

Explanation:

A free body diagram is a diagram which shows all the forces acting on an object.

The problem asks us to find the free body diagram of block A, so we must find all the forces acting on block A.

We have 3 forces acting on block A in total:

- The force of gravity (its weight), which pushes the block downward (in the diagram, it is the force represented with [tex]F_{gA}[/tex]

- The tension in the rope 1, which pulls block A upwards: this force is represented with [tex]F_{T1}[/tex]

- The tension in the rope 2, due to the weight of block 2, which pulls block A downwards: this force is represented with [tex]F_{T2}[/tex]

Based on the direction of these 3 forces, the correct diagram is the 3rd one.

What are ph levels? Why are they important? What’s there acceptable level/condition?

Answers

The PH level is how acidic or basic something is. the scale goes from 0 to 14 with 7 being neither acid nor base

pH measures the acidity or alkalinity of a substance, with 7 being neutral.

The term pH is a measure of how acidic or alkaline (basic) a substance is. The pH scale is logarithmic and ranges from 0 to 14, where 7 is considered neutral. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity. The acceptable level of pH varies depending on the substance and the biological system. For example, in humans, the normal range of blood pH is between 7.35 and 7.45, which is slightly alkaline. Conditions such as acidosis and alkalosis occur when the blood pH falls too low or rises too high, respectively.

Maintaining a consistent pH is crucial in living organisms to ensure optimal conditions for chemical reactions. Even small fluctuations in pH levels can affect protein structure and function, which is critical for life processes. Outside of biological systems, pH levels are also significant in environmental contexts, such as the impact of Acid Rain on the pH of natural waters, which is important for the survival of aquatic life.

It is defined as "an increase in the frequency of sound, light or other waves as the source or observer moves towards each other".This effect causes the sudden change in pitch noticeable in passing siren.   You hear a siren from a few blocks away. The source is a police car that is racing in your direction. As the car approaches, zooms past you, and then speeds off into the distance, the sound of its siren keeps changing in pitch. First the siren gets higher in pitch, and then it suddenly gets lower.

C. If a positively charged rod is brought close to a positively charged object, the two objects will repel.

D. If a negatively charged rod is brought close to a positively charged object, the two objects will repel.

Answers

The only correct statement on that list is choice-C:  If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Answer:

C. If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Explanation:

According to coulomb's law, the magnitude of the electric force between two point charges at rest is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them. This force is repulsive for like charges and attractive for opposite charges.

A. the forces pointing up and down are unbalanced.
B. The forces pointing in and down are balanced
C.The forces pointing right and left are balanced
D.There is a net force of 200 N to the left

Answers

B) The forces pointing in and down are balanced 

300n on the top and 300n on the bottom results in it being balanced

In the given diagram, the forces pointing up and down are balanced since they are equal in magnitudes and will cancel each other in magnitude.

What is force?

Force acting on an object is able to deform it or to change its state of motion or rest. Force is a vector quantity and is characterised by its magnitude and direction.

When two same or different forces are acting in the same direction on an object, the resultant force will be the sum of magnitude of the two forces. If two forces are acting in the opposite directions, they will cancel each other in magnitudes.

In the given diagram, the force acting up and down are equal thus, they will cancel each other and is said to be balanced. The net force to the right direction is 200 N since 200 from 400 N is cancelled by the force with 200 N leftwards. Hence, option b is correct.

If you know the amount of air pressure exerted on a tabletop, how can you calculate the force exerted on the tabletop? Multiply the air pressure by the area of the tabletop. Divide the air pressure by the area of the tabletop. Divide the area of the tabletop by the air pressure. Add the air pressure and the area of the tabletop.

Answers

Answer:

Multiply the air pressure by the area of the tabletop.

Explanation:

The relationship between pressure, force and area is given by:

[tex]p=\frac{F}{A}[/tex]

where in this case, p is the air pressure, F is the force exerted and A the area of the tabletop. By re-arranging the equation, we can solve for F, the force exerted:

[tex]p=\frac{F}{A}\\p\cdot A=\frac{F}{A}\cdot A\\pA=F[/tex]

So, the correct answer is:

The force exerted on the tabletop can be found by multiplying the air pressure by the area of the tabletop.
