what is the impulse applied to the block

Answer:

A

sound waves are longitudinal waves with the oscillation parallel to the direction in which energy is transferred

A longitudinal wave with the oscillation parallel to the direction in which energy is transferred is the correct. Therefore option A is correct option.

Electromagnetic wave are the wave that contains both electric wave and magnetic wave. These two waves are perpendicular to each other. There are two kinds of this wave, one is longitudinal wave and transverse wave.

When movement of particles of wave move parallel to the direction of wave propagation. To go in parallel direction, there is two way one is in the direction of propagation or anti to the direction of propagation. Transverse is the wave in which wave particle travel perpendicular to the direction of propagation.

The wave that is present in the sound wave is the longitudinal wave.  A longitudinal wave with the oscillation parallel to the direction in which energy is transferred. Therefore option A is correct option

Newton's 2nd law

[tex]\tt \sum F=m.a[/tex]

input the value:

[tex]\tt m=\dfrac{\Sum F}{a}=\dfrac{140~N}{15~m/s^2}=9.3~kg[/tex]

The mass of the ball, that  person throws, is 9.33 kg.

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.

The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

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

Force applied on the ball = 140 N.

Acceleration of the ball = 15 m/s².

According to Newton's 2nd law of motion:

Force = mass × acceleration

Mass = force ÷ acceleration

= 140 N ÷ 15 m/s²

= 9.33 kg.

Hence, the mass of the ball is 9.33 kg.

Let there be light! At the flick of a switch, a light bulb can light or illuminate an entire room, but what else is happening? One the basic laws of physics, the conservation of energy, tells us that energy is neither created nor destroyed: rather, it can only be transformed from one form to another. In the case of the light bulb, electrical energy is being transformed into light and thermal (heat) energy. Different wattages and types of bulbs give off varying amounts of light and heat. In this light bulb science project, we'll be working with incandescent and compact fluorescent lamp bulbs (CFL’s).

Answer:

The magnitude or strength of an electric field in the space surrounding a source charge is related directly to the quantity of charge on the source charge and inversely to the distance from the source charge. The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge.

Explanation:

I really hope this helps you!

The rank for the strength of electric field can be given as D>B>E>C>A. The amplitude or intensity of such an electric field inside the region around a source charge is proportional to the amount of charge.

Electric field lines are a paper representation of electric field lines. These are drawings that employ lines and arrows to illustrate electric fields surrounding charged objects, making them highly useful in understanding field intensity and direction.

The amplitude or intensity of such an electric field inside the region around a source charge is proportional to the amount of charge just on source charge as well as inversely proportional to the distance first from source charge. The rank for the strength of electric field can be given as  D>B>E>C>A.

Answer:

Container 1

Explanation:

The reason why there will be less pressure in container 1 is that it's colder than container 2. You must have learned right, that a colder thing has its molecules less moving, and they don't expand, instead they actually decrease in volume? In the same way, it's applied to gas also. So that's why, because container 1 has 15C temperature, which is half less than container 2's 30C, that's why, container 1 has less pressure than Container 2.

So hence, container 1 has less pressure than container 2 because of its a lower temperature, which doesn't make the molecules expand, and move around that much.

Answer:

The answer is T (True)

Explanation:

Answer:

The first part of the question is asking about BUOYANT FORCE or UPTHRUST.

Upthrust =TRUE WEIGHT-APPARENT WEIGHT

TRUE WEIGHT=mg

TRUE weight=50kg×10m/s²

=500N

upthrust=500N-380N

FB=120N

volume of the rock=mass/density.

since the granite is completely submerged, the volume of the displaced liquid will be equal to the volume of the body.

upthrust=Vdg

120N=V×1000kg/m³×10m/s²

120N=V×10000kg/m²s²

120/10000=V

v=0.012m³

Answer:

Hooke’s law can be applied to all materials which come back to original shape upon withdrawal of the load. It is applicable to all materials which follow the linearity of stress and strain in the elastic limit. Any object made of steel or aluminum or any other metals that follows the stress-strain linearity in the elastic zone uses Hooke’s law.

Explanation:

Answer:

No.

Materials which obeys Hook's law are called elastic material.

Elastic material are material which return to their original shape and size after force deforming them is removed.

Answer:

Line C

Explanation:

Hi there!

Speed is equal to Distance divided by Time:

speed = distance / time

Notice how distance is the dependent value on the graph, lying on the y-axis, and time is the independent value on the graph, lying on the x-axis.

The slope of a line is equal to Rise divided by Run:

slope = rise / run

"Rise" means the number of units the line travels up in the y-direction and "run" means the number of units the line travels to the right in the x-direction.

This makes the "rise" of the line equivalent to the distance, and the "run" of the line equivalent to time.

Therefore, speed = slope.

To find the line that shows the object moving at its fastest speed, we must find the line with the greatest slope (or the steepest going up).

That would be line C.

Answer:

9.8 N downward

Explanation:

The weight force is defined as w = mg, where m is the mass of the object and g = 9.8 m/s^2. Plugging in values shows that the force exerted on the ball is 9.8 N, downwards toward the ground.

Answer:

V1 A1 = V2 A2

V1 = 10m/s

A1 = 8m

10x8 =80

V2 =?

A2 = 4m

80 = V2 x 4

÷4

20 = V2

V2 =20m/s

Explanation:

If one halfs, the other doubles & vice versa. (Like inverse proportion or the reciprocal). That's why when you half 8m, the velocity doubles, on the other side. Then, balances out.

Explanation:

[tex]a = \frac{f}{m} = \frac{1}{3 }kg[/tex]

Answer: 66 kg m/s

Explanation:

The equation for Momentum is

p=mv

where P is momentum

m is mass

and v is velocity (speed)

Since we have both mass and velocity all we have to do is multiply the mass and velocity to get momentum

12kg * 5.5 m/s = 66 kg m/s

Answer:

The plane would need to travel at least [tex]8,\!580\; {\rm ft}[/tex] ([tex]8.58 \times 10^{3}\; {\rm ft}[/tex].)

The [tex]10,\!000\; {\rm ft}[/tex] runway should be sufficient.

Explanation:

Convert unit of the the take-off velocity of this plane to [tex]\rm ft\cdot s^{-1}[/tex]:

[tex]\begin{aligned}v &= 180\; {\rm mph} \\ &= 180\; {\rm mi \cdot hrs^{-1}} \times \frac{1\; {\rm hrs}}{3600\; {\rm s}} \times \frac{5280\; {\rm ft}}{1\; {\rm mi}} \\ &= 264\; {\rm ft \cdot s^{-1}}\end{aligned}[/tex].

Initial velocity of the plane: [tex]u = 0\; {\rm ft \cdot s^{-1}}[/tex].

Take-off velocity of the plane [tex]v =264\; {\rm ft\cdot s^{-1}}[/tex].

Let [tex]x[/tex] denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation [tex]x = ((u + v) / 2) \, t[/tex].

Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration [tex]t[/tex] times average velocity [tex](u + v) / 2[/tex].

The distance that the plane need to cover would be:

[tex]\begin{aligned}x &= \left(\frac{u + v}{2}\right)\, t \\ &= \frac{0\; {\rm ft \cdot s^{-1}} + 264\; {\rm ft \cdot s^{-1}}}{2} \times 65.0\; {\rm s} \\ &= 8.58\times 10^{3}\; {\rm ft}\end{aligned}[/tex].

Answer:

V1 = S / t1 = speed up stalled escalator = 10/94 = .106 m/s

V2 = S / t2 = speed of escalator = 10 / 60 = .167 m/s

V = V1 + V2     combined speed

T = S / V = 1 / t1 + 1 / t2 = t1 * t2 / (t1 + t2)

T = 60 * 94 / (60 + 94) = 36.6 sec

Check: combined speed = .106 + .167 = .273 m/s

T = 10 / .273 = 36.6
