Answer:Astronomers often use the astronomical unit to describe distances within solar systems because it is convenient and easier to understand. The astronomical unit (au or AU) is defined as exactly 149,597,870,700 meters (about 93 million mi), which is roughly equal to the average distance between the Sun and Earth.

Answer: they are compression waves

Explanation:

The unique property of light waves is that they do not require a medium for propagation.

Generally; waves are classified into electromagnetic waves and mechanical waves. Mechanical waves require a medium of propagation while electromagnetic waves do not require a medium for propagation.

Also, waves are classified into transverse waves and longitudinal waves. In transverse waves, the disturbance is perpendicular to the wave front while in longitudinal or compressional waves, the disturbance is parallel to the wave front.

Light is both an electromagnetic wave and a transverse wave. This means that it requires no material medium for propagation. This is the unique property of light waves.

Tbh I dont have an explanation I just wanted to give the answer but its for sure correct!

yesssss I am agree ......

Answer:

Yes, I agree. The pressure exerted upon the floor is larger for high heel shoes than flat shoes, hence causing more damage to the floor.

Explanation:

Pressure is force/area. High heel shoes have a sharp point at which they touch the floor, while flat shoes have a flatter surface at which they touch the floor. Due to you exerting the same force anyway, the area is smaller for high heel shoes.

As you might know, the smaller a denominator is, the larger the number is. As an example, 3/1 is larger than 3/2. 3/1 is 3, and 3/2 is 1.5. Hence, the force is larger for high heel shoes, and it will cause more damage.

La respuesta correcta es 180 centímetros cúbicos o 180 [tex]cm^{3}[/tex]

Explicación:

El primer paso para saber cuanto alcohol desaloja el prisma es calcular el volumen total del prisma. El volumen se puede encontrar usando la formula V (Volumen) = B (base) x h (altura). El proceso se muestra a continuación:

V  = B x h

V = 36 [tex]cm^{2}[/tex] x 10 cm

V= 360 [tex]cm^{3}[/tex]

Finalmente, el volumen total del prisma debe dividirse en 2 considerando que solo la mitad del prisma fue sumergida y esta mitad equivale al volumen del alcohol desplazado.

360 [tex]cm^{3}[/tex] ÷ 2 = 180 [tex]cm^{3}[/tex]  

El volumen de fluido desplazado es de 180 cm^3.

Sabemos que el objeto va a desplazar su propio volumen de fluido. Por lo tanto, necesitamos obtener el volumen del objeto a, este es el volumen del fluido que eventualmente será desplazado por el sólido.

El volumen del sólido es;

V = 36 cm^2 * 10 cm^2 = 360 cm^3

desde que se sumergió a la mitad, volumen de alcohol desplazado = 360 cm^3/2 = 180cm^3

Explanation: sry if wrong

Answer:

no change

Explanation:

The Newton's Second Law of motion states that when an unbalanced force is applied to an object, it causes an accelerated motion in the object, in the direction of the unbalanced force. So, if there is no unbalanced force, then there is no motion. In this case both the forces have same magnitude and opposite direction. Therefore, the unbalanced force will be zero:

Unbalanced Force = Upthrust - Weight

Unbalanced Force = 2448 N - 2448 N

Unbalanced Force = 0 N

hence, there will be no motion in the vertical direction. Therefore, the correct option is:

no change

Answer:

Total distance = 6.5 km

Explanation:

Let the distance be denoted by the vectors drawn from A, B, C, D, E, and F.

Then the distance covered can be calculated by adding the vectors in the direction given.

Total distance = 3km + 1km+ 1.5km+ 0.5km+ 0.5km

Total distance = 6.5 km

If we were to find the displacement ( shortest distance) then the head to tail rule would be applied using the vectors.

Answer:

Explanation:

Given

Speed v =27m/s

Distance covered after skidding = 41.5m

Acceleration a = ?

Using the equation of motion

v² =u²+2aS

27² = 0²+2a(41.5)

729 = 0+83a

a = 729/83

a = 8.78m/s²

Hence it's acceleration is 8.78m/s²

Answer:

210 km

Explanation:

60 x 3  1/2 = 210

Answer:

a' = 2a

Explanation:

The acceleration during this circular motion is the centripetal acceleration. Initially, the acceleration will be given as:

a = v²/r   --------------------- equation (1)

Where,

a = centripetal acceleration at outer edge

v = speed of merry go round = 5 m/s

r = distance from center of round to person (outer edge)

Now, when the person moves half way towards center. Then, the acceleration becomes:

a' = v²/r'

where,

r' = r/2

Therefore,

a' = v²/(r/2)

a' = 2v²/r

using equation (1):

a' = 2a

Given :

You fire a paintball from a paintball gun straight up into the air at 25.0 m/s.

To Find :

What is the ball velocity at the higher point that the ball reaches.

Solution :

We know, when ball is moving upward acceleration due to gravity is applied downward.

So, the ball will decelerate and when ball reaches maximum height its velocity will become zero.

Therefore, ball velocity is 0 m/s at maximum height.

Hence, this is the required solution.

Answer:

so, the answer is 56 whole number if round it, or 55.6(round it to 10th decimal)

Explanation:

(formula, idk it is wrong or right)   °C =°F - 32 then / 1.8000

44°F =  6.6666666667°C

-56°F = -48.888888889°C

So, if u want whole number as the answer

it is something like 6.6666666667°C +  48.888888889°C = 55.5555555557 °C

so, so, the answer is 56 whole number if round it, or 55.6(round it to 10th decimal)

P = 3000 Pa

Explanation:

Weight of Dorji, W = F = mg = 1500 N

The total surface area of soles of his feet is 0.5 m²

We need to find the pressure exerted by his body on the ground​. The pressure is equal to the force acting per unit area. So,

[tex]P=\dfrac{1500\ N}{0.5\ m^2}\\\\=3000\ Pa[/tex]

So, the pressure exerted by his body on the ground​ is 3000 Pa.

Answer:

Q1: I'm going to say the fence is a polarizing filter.

Q2: On the second question: (b). BTW, It's not a very well-phrased question (and I'm a particle physicist, so...)

Explanation:

Q1:

So... hard to say for sure the intent here without knowing what you've been learning in class, but a frisbee - being a flat disk - will only go through the fence if it is oriented as shown, much like polarized light will only go through a polarizing filter if the EM waves are polarized in the direction that they will pass through a polarizing filter.

Q2:

It's not a) because ALL waves require a source of energy.  

b) is for sure true and is about energy transfer - mechanical waves need a medium (like water) but EM waves do not. (Early on they thought maybe there was a medium for EM waves... they called it "aether" ... but it was proven via the Michealson-Morley experiment that no the speed of light was an absolute constant - fundamental to special relatively - which meant that light did not travel in any medium!)

(c) - depends on what you mean by "vibration", but yeah... EM waves result in varying electric fields for an observer. However, nothing to do with energy transfer per se (except that those varying fields are what transfer energy to objects that experience them...)

(d) - As above, the speed of light is a constant - cannot change speed ever *in a vacuum*.  However, the speed of light is different in various materials, and can be bent (refracted) or reflected, which means the fields change direction in interacting with matter, although they do not change speed or direction "on their own" (in a vacuum).  Similarly, mechanical waves can change speed or direction when there are changes or discontinuities in the media they travel in.  So, arguably about energy transfer (the direction and speed related to the direction and rate of energy transfer) but not really different between EM and mechanical waves.

Anyway, like I said, it's not a very clear question, so YMMV with my advice here, but (b) is for sure the best single choice.
