You may have had an opportunity to skip rope or watch someone else skip rope. If you have one rope, you can skip a yourself or you can include two friends, each friend holding one end of the rope and you skipping in the middle. In this instance your friend represent notes and you were anti-node. Is it possible to skip rope with three friends with two of you in yhe middle jumping at different times?.

Answer:

Explanation:

This is a displacement vector since it is given in terms of a distance (meters, to be specific). The way you find the x-component is:

[tex]V_x=Vcos\theta[/tex] which means you multiply the magnitude (length) of the vector times the cos of the direction (the angle):

[tex]V_x=2.5cos(64)[/tex] to get

1.1 m, choice B.

Answer:

A. If motion starts and stop at the same location, then the displacement is zero

C. Distance is always greater than or equal to the magnitude of the displacement

Explanation:

The displacement of a body is a vector quantity that gives the shortest (straight line) distance moved by an object in motion, from its initial position to its final position. The displacement can also be described as the final position relative to the initial position of an object, such that the displacement vector, 's', is given as follows;

[tex]s = x_f - x _i[/tex]

The displacement gives the direct length between two points, with regards to the direction of motion between the points. It can only be described by both the magnitude and the direction

Therefore, displacement can be positive (forward motion), negative (backward motion), or zero (where there is motion that stops at the starting point)

Therefore, a correct options is; If motion starts and stop at the same location, then the displacement is zero

Displacement, being a vector quantity will have both magnitude and direction

Distance, however, is a scalar quantity, it specifies only magnitude, but does not specify direction

Distance, describes the length of the path taken from one point to the other. Distance gives the total movement a body makes, without regards to the direction of the motion

Therefore, distance is always positive or zero (here only the object is stationary)

Therefore, a correct option is; Distance is always greater than or equal to the magnitude of the displacement

Therefore, the correct options are;

If motion starts and stop at the same location, then the displacement is zero

Answer:

All matter is made up of atoms.

Answer: rarefaction

Explanation: correct answer on a p e x

Rarefaction term describes an area of low density in a longitudinal wave.

Wave is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave. Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave. Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a transverse in nature wave.  

In Longitudinal wave, wave carries energy and momentum with compression and rarefaction. Compression is region of high density, in this region particles of the medium is compressed. rarefaction is region of expansion and it is low density region of longitudinal wave.

Hence option C is correct.

Based on what we have learned so far, in what ways have the experiences of Asian-Canadians stayed the same over time? Why do you think these similarities exist? Please give specific examples to support your ideas.

Explanation:

Answer:

6.58×10⁶ F

Explanation:

Applying,

Q = CV..................... Equation 1

Where Q = charge of the capacitor, C = Capacitance of the capacitor, V = Volatage

Make C the subject of the equation

C = Q/V................. Equation 2

From the question,

Given: Q = 7.9×10⁷ C, V = 12.0 V

Susbtitute these values into equation 2

C = 7.9×10⁷/12

C = 6.58×10⁶ F

Answer:

9.7 miles per second

Explanation:

divide 200 by 20.6

Let's just suppose this situation, so it's like this;

Q --------------- q --------------- Q

Now, acc. to the question, the system is equilibrium which means that possibly both the Q should be exerting some pressure on the middle charge q, so let's suppose Q be +ve and q be -ve

The charge that we have kept at a certain distance something like this;

+Q --------------- -q --------------- +Q

<––– d ––– > <––– d ––– >

Now, we +Q will be exerting some force on the another +Q that it should be acc. to columbs law like this;

F = k × Q1Q2/r²

F = k × QQ/(2d)²

F1 = k × Q²/4d²

Also, when this +Q will exert force on -q, it could be written as;

F = k × Q1Q2/r²

F2 = k × Qq/d²

From the question, we know that the system is a equilibrium which means that these two force F1 and F2 will be equal to each other;

= k × Q²/4d² = k × Qq/d²

= Q/4 = q

= Q/4 = -q

= -Q/4 = q

So, the charge on q is -Q/4.

Experimental evidence that supports the new idea

Answer:

They gain kinetic energy

Explanation:

When the temperature of the particles in a substance rise, its internal energy increases. This internal energy is thus translated to kinetic energy of the particles in the substance. If the substance is a solid, as the kinetic energy increases, the vibrations of the particles of the substance increases causing it to undergo a change of state to liquid when the temperature reaches its melting point.

This change of state also occurs from the liquid state to the gaseous state as the internal energy of the substance, and thus the kinetic energy of the particles increase when the temperature reaches the substance's boiling point.

So, as the temperature of a substance rises, the particles of the substance gain kinetic energy.

Answer:

Sentence III

Explanation:

I. It takes positive work to bring like charges together.

Using Coulom law we know that like charges will feel a repulsion force that meen that if we want to put them together we are going againt the force, this means we need a negative work. So is False.

II. Electric field lines always point in the direction of decreasing electric potential.

The elctrical fiels depend on the charge of the particle. So if the particle is positive the field will point always outwart the charge, and if the particle is negative, the electric field will point to the charge. Also, we know that the potential is bigger clouser to the charge, so this sentence is folce when we have a negative charge. So is False.

III. If a negative charge moves in the direction of the electric field, its potential energy decreases

If a negative particle move in the direction of the elctric field in bout cases the potential will decrease. If we have a positive charge the electron will be atracted by the field, How ever the electric fild is pointing in the other direction, for that reason will decrease.

8892 ml = 8892 gm = 8892000 mg

1 ml = 1 gram

8892 ml = 8892 gram

1 gram or ml = 1000 milligram

8892 ml = 8892 × 1000 = 8892000 milligram

hope this helps

have a good day :)

Explanation:

remember: 1 kilogram = 1000 gram = 1000000 milligram.

Milliliter is expressed same as gram and liter is expressed same as kilogram.

1 meter = 100 cm, 1 kilometer = 1000 meter,

1 cm = 10 millimeter.

You can't convert ml to gm unless you know the substance. They're all different.

Answer:

Critical angle

Explanation:

The angle of incidence when the refracted angle is 90°; we have the critical angle at this point. At this point, the refracted ray lies between the boundary between the two medium, this is the angle just before total internal reflection occurs, as the refracted angle exceeds 90°, all rays are reflected. Hence, we can conclude that it is the largest angle at which reflection can still occur.
