Answer:

Longitudinal wave

Explanation:

Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.

Answers

Answer:

the answer for how much work was done is 90

Work done to push a box is 150 J.

What is work?a force appearing upon an item to purpose a displacement.WORK = FORCE * DISPLACEMENTmechanical conservation of energy is the change in kinetic energy is equal to the work done.work energy theorem states that total energy change is equal to work done.

force= 30N

Why do we resort to violence when we are faced with adversity?

Answers

Well adversity is hard time or misfortune.
We turn to violence to express emotion.

I believe we resort to violence when faced with adversity because it becomes difficult to deal with. Being in a rough situation cause distress. That builds up and when a person can no longer hold it in, they can get violent. Turning to violence becomes their way of “letting it out”.

A girl weighing 500 Newtons takes 50 seconds to climb a flight of stairs 18 meters

high at a speed of 0.36 m/s. Her power output vertically is-

Answers

Answer:

180Watts

Explanation:

Power = Force * distance/Time

Given

Force = 500N

Distance = 18m

Time t = 50secs

Substitute into the formula

Power = 500*18/50

Power = 10 * 18

Power = 180Watts

Hence her power output vertically is is 180Watts

A sound wave produce by a chime 515 m away is heard 1.50 s later.What is the speed of the sound in air?

Answers

Answer:

the seed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance divided by Time

So, here speed be 515m

And, the time is 1.50 second

So, the speed of the sound is

= 515m divided by 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s

The first charge is pulling on the second. Is the second pulling on the first? Explain your reasoning

Answers

Answer:

law of action and reaction.

Explanation:

In Newton's three laws it is established that forces act in pairs, if one body interacts with another the second interacts with the first, this is the so-called law of action and reaction.

In this case, when the first load pulls on the second, the second pulls on the first, the two forces are not canceled because each one is applied to a different body.

Therefore the magnitude of the forces is the same, but the direction is opposite and each one is applied in a body

An electric force is an attractive or repulsive interaction. Newton's laws of motion define how it affects things, just like any other force. Yes, the second pulling on the first.

How does Newton's third law explain in terms of electricity?

An electric force is an attractive or repulsive interaction between any two charged things. Newton's laws of motion define how it affects things, just like any other force.

The motion of objects under the influence of such a force or combination of forces is studied using Newton's laws.

The analysis generally starts with the creation of a free-body diagram in which the kind and direction of the various forces are represented by vector arrows.

Newton's laws of motion define how it affects things, just like any other force. Hence Yes, the second pulling on the first.

A convex lens is a type of lens that is projected outwards and shows the real image of an object.  Whereas a concave lens is curved inwards and shows virtual image of objects.

The image formed at by the location of convex lenses beyond 2F is inverted, smaller and and real image. If it is at 2F, the image is inverted with the same size and real. If the lens is placed between F and 2F the image formed is beyond 2F and it will be inverted, enlarged and real.

If the object is at F , no image will be formed. If it at between F and the lens, then the image forms beyond 2 F which is upright, enlarged and virtual.

A force of 500N Is applied to a steel wire of goss_sectional area 0.2m2 the tensele stress is a. 2.5x10 1nm-2 b. 1 0x102nm-2 c. 2.5x103nw-3 d. 1.0x103nm-2

Answers

Answer:

the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².

Explanation:

Given;

applied force, F = 5000 N

cross sectional area of the steel wire, A = 0.2 m²

The tensile stress of the steel wire, is calculated as;

[tex]\sigma = \frac{F}{A} \\\\\sigma = \frac{500}{0.2} \\\\\sigma = 2500 \ N/m^2\\\\\sigma = 2.5 \ \times \ 10^3 \ Nm^{-2}[/tex]

Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
