will an object have the same weight on moon as it does ?

Answers

Answer:

The mass of an object is the same everywhere either on earth or moon.

The weight of an object depends on a gravitational acceleration and it's different from one on earth and that on moon.

therefore the weight changes but the mass is the same.

Volcanic Island Arcs, such as Japan, form when a(n) __________ plate is subducted below a(n) _________________ and takes seawater with it. A rock and water mixture will break through the crust.

Answers

Volcanic Island arcs form when an oceanic tectonic plate is subducted below a tectonic plate  taking seawater with it.

Volcanic island arcs occur offshore during volcanoes. They occur due to the subduction of an oceanic plate under another tectonic plate. Volcanic Island arcs occur mostly in ocean basins.

Due to the subduction of oceanic plates under tectonic plates, Island Arcs are found, mostly along the margins of continent.

Hence we can conclude that Volcanic Island arcs Form when an oceanic tectonic plate is subducted below a tectonic plate  taking seawater with it.

light waves are first transmitted through the ________ at the front of the eye and enter an opening called the ________ before shining onto the retina.

Answers

The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.

Light waves can be regarded as moving energy which contains microscopic particles known as photons. The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;Light will move through the (cornea) which is situated at the front area of the eyes into lens. Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .Then through the help of the cells in the retina, the light will be absorbed and then be converted to  electrochemical impulses and then transfer it to the brain as well as optic nerve.

Therefore, light wave are form of tiny microscopic particles.

if please mark brainiest

John Dalton described atoms as small spheres that could not be divided into anything smaller.

Who was John Dalton?

John Dalton is the scientist who described atoms as small spheres that could not be divided into anything smaller. He proposed his atomic theory in 1803, which included the postulate that all matter is composed of tiny, indivisible particles called atoms. D

Dalton's theory also stated that atoms of different elements are unique in their mass and chemical properties and combine in simple whole-number ratios to form compounds. Dalton's model of the atom was a solid, indivisible sphere that was the smallest possible unit of an element.

While this model has been refined and updated with new discoveries, Dalton's contributions laid the foundation for the modern understanding of atomic structure and chemical reactions.

What is the car's acceleration

Answers

Answer:

The acceleration of the car was one meter per second squared.

Explanation:

We can use one of the kinematic equations:

[tex]\displaystyle v_f = v_i + at[/tex]

Where v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time (in seconds).

The final velocity is 40 m/s, the initial velocity is 35 m/s, and the time is 5 s. Substitute and solve for a:

[tex]\displaystyle \begin{aligned}(40 \text{ m/s}) &= (35 \text{ m/s}) + a(5\text{ s}) \\ \\ 5 \text{ m/s} &= a(5\text{ s}) \\ \\ a &= 1\text{ m/s$^2$} \end{aligned}[/tex]

In conclusion, the acceleration of the car was one meter per second squared.

Sue and Jenny kick a soccer ball at exactly the same time. Sue’s foot exerts a force of 68.9 N to the north. Jenny’s foot exerts a force of 85.4 N to the east.
a) What is the magnitude of the resultant force on the ball?
Answer in units of N.

Answers

Explanation:

the magnitude of the resultant force =

√(68.9² + 85.4²)

=√(4,747.21 + 7,293.16)

=√12,040.37

= 109.7 N

♪Answer :

»Sue's style feet (north) = 68.9N

»Jenny style feet (East) = 85.4N

So, the resultant force on the ball is

= √(68.9² + 85.4²)

= √(4,747.21 + 7,293.16)

= √(12,040.37)

109.72N

A 3000-kg spaceship is moving away from a space station at a constant speed of 3 m/s. The astronaut in the spaceship decides to return to the space station by switching on engines that expel fuel so that the sum of the forces exerted on the spaceship by the expelled fuel points toward the space station. What is the magnitude of the minimum force needed to bring the spaceship back to the space station

Answers

Answer:

P = m (v2 - v1)     change in momentum

P = - m v1  if v2 is to be zero

F = P / t     change in momentum equals applied force

F = m a = - m v1 / t

a = -v1 / t     or a * t = -v1`

Any combination of a and t that is greater than v1 will bring the space station to a halt

If a is small then t must be large

Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point

A bullet is fired horizontally at 343 m/s from the top of a building where height is 37.3 m. The built will be
in flight for seconds

Answers

Answer:

Explanation:

A classic projectile motion question. Horizontal motion does not matter whatsoever in the context of this equation as we are looking at the vertical component of velocity only. Since the question states that it is fired horizontally, there is no vertical component of velocity. Thus, v0y = 0.

Assuming the projectile is on the Earth, we can use the free-fall acceleration, 9.8 m/s^2.

The question gives us Δy, which is 37.3m.

Using the second kinematics equation, Δy = v0t + (at^2)/2, we can substitute in the values.

37.3 = 0 + 0.5(9.8)t^2

37.3 = 4.9t^2

7.61224489796 = t^2

t = 2.75902970226 seconds.

6. A surface receiving sound is moved from its original position to a position three times fa
received sound thus becomes
O A. three times lower
O B. nine times lower.
O C. three times higher.
O D. nine times higher.

Answers

Answer: Answer is D

Explanation:

A surface receiving sound is moved from its original position to a position three times farther away from the source of the sound. The intensity of the received sound thus becomes nine times as low.

A surface receiving sound is moved from its original position to a position three times farther away from the source of the sound. The intensity of the received sound thus becomes nine times lower . Option(B) is correct.

What is intensity of sound?

The power of sound per unit area is used to define sound intensity. The measurement of sound intensity in the air is the typical context. The surface of the sound source also plays a role. The kinetic energy of the mass of air is produced by the source's and the vibrating surface's increasing amplitudes.

With the air's mass vibrating and with its average speed, this kinetic energy rises. The distance from the sound source affects how strongly the ear perceives a sound. The characteristics of the elastic medium between a sound source and the ear also affect intensity. The sounds are weakened by non-elastic materials like wool, felt, etc.

Mathematically: sound intensity = acoustic pressure/normal area to the direction of propagation.

So, when a surface receiving sound is moved from its original position to a position three times farther away from the source of the sound, its normal area becomes 9 times larger and intensity of the received sound thus becomes nine times lower .

What happens to the density of a fluid as it temperature increases/decreases?

Answers

Let's look at the density of water at 25 deg C and compare that to a higher temperature, 80 deg C. The density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is added to the liquid water, there is greater kinetic energy of the molecules and there are also more vibrations of the water molecules. Together these mean that each H2O unit in liquid water takes up more space as the temperature increases.
