Explanation:

the close molecules in solids allows sound to travel at a faster speed

Sound will move quicker through Steel than in water and air.

Sound: This can be defined as an audible form of energy, that is radiated outward from a source.

⇒ Generally,

Sound wave travels fastest in solid,  more than in liquid or gas. This is because the molecules of solid are more closely together.

⇒ From the question above,

Therefore, sound will move quicker through Steel than in water and air.

Hence: sound will move quicker through Steel than in water and air.

975 J of heat energy is needed to increase the temperature from 150°C to  250°C of given mass of gold.

From specific heat formula,

[tex]Q = mc \Delta T[/tex]

Where,

[tex]Q[/tex] - Heat absorbed

[tex]m[/tex] - mass of  gold = 75. 0 g

[tex]c[/tex] - specific heat of gold = 0. 13 J/g°C

[tex]\Delta T[/tex]- temperature difference =  150°C -  250°C = 100°C

Put the values in the formula,

[tex]Q = 75\times 0.13 \times 100 }\\\\Q = 975 {\rm \ J}[/tex]

Therefore, 975 J of heat energy is needed to increase the temperature of given mass of gold.

https://brainly.com/question/1209542

The heat required to increase the temperature of the gold is 980 J

The correct answer to the question is Option B. 980 J

We'll begin by calculating the change in the temperature of the gold

ΔT = T₂ – T₁

ΔT = 250 – 150

ΔT = 100 °C

Finally, we shall determine the heat required.

Q = MCΔT

Q = 75 × 0.13 × 100

Q = 975 J

Q ≈ 980 J

The correct answer to the question is Option B. 980 J

Basically your liquid will go over the line because you are adding more mass. the balloon will inflate because  of mass filling it.  Part 1  I noticed that there was a change from the original line.   part 2  Some mass is lost. The bubbles are the gas leaving. The balloon increases in size because of the mass. The cup got heavier when I added the vinegar.

Gas leaving caused the bubbles.

cause there's no gravity therefore they appear weightless

Answer:Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth's Moon.❤

Mars, the Moon, and Jupiter, Where we have found evidence of the early history of Earth.

The giant-impact theory is currently the one that is most frequently accepted. According to this theory, the Moon was created after the Earth collided with a smaller planet that was around Mars' size.

The Moon was created when the impact's leftover debris gathered in an orbit around Earth. The main asteroid belt, which extends between Mars and Jupiter, is home to the majority of this old space debris.

Asteroids range in size from the largest, Vesta, which has a diameter of roughly 329 miles (530 kilometers), to bodies that are about 33 feet (10 meters) wide. The cumulative mass of all asteroids is less than that of the moon on Earth.

If the person inserted a nail with a hammer instead of the screw with the screwdriver, the force applied would be greater, but the distance would be shorter. The correct option is A.

The action of push or pull in order to make a body change its state of motion or rest is called Force.

As the force is pressure per unit area. Force is inversely proportional to the area over which force is to applied.

The hammer would take more force to insert the nail. The screw has its helix which is to be inserted and application of force is small.

Thus, the force applied would be greater, but the distance would be shorter.  The correct option is A.

Answer:

Galaxies are too far away for astronomers to take real 3D measurements, but we can infer their shape based on the movement of stars. ... This is also true of less common spiral galaxies like the Milky Way. The bulge near the center contains older stars, while the flattened arms are home to younger ones.

Explanation:

The orbits of stars can also affect the shape of a galaxy through a variety of density waves that are produced when material is compressed into something comparable to a traffic jam in galaxies.

A star is defined as a celestial object consisting of a luminous sphere of plasma held together by self-gravity where the closest star to Earth is the Sun. While many other stars are visible to the uncovered eye at night, their extreme distance from Earth causes them to appear as fixed points of light.

Galaxies are too far away for astronomers to take true 3D measurements, through which we can estimate their size based on the motion of stars, which is also true for less common spiral galaxies like the Milky Way.

Thus, the orbits of stars can also affect the shape of a galaxy through a variety of density waves that are produced when material is compressed into something comparable to a traffic jam in galaxies.

Answer:

0.667; 4.965

Explanation:

Look at the picture I attached for the force analysis.

a) The coefficient=Friction/Normal Force. Because it's at constant speed, the force of friction + mgsin58.1° (because it's on an inclined plane and has split forces) is equal to the applied force (70.4N). Normal force is not equal to weight force though, because the box is on an inclined plane; it's equal to mgcos58.1°.

b) If it were to break, then the box no longer has an applied force, and the direction of friction has changed to up the inclined plane. F=m/a, so acceleration = mgsin58.1°- Friction/mass

The characteristics of parallel circuits allow to find the correct answer for the question about what happens when a light bulb is:  

   D) Bulb 2 will stay lit and the light source will be stronger.

Electrical circuits have two forms and connection:  

   • Serie. In this case there is only one path through which current can circulate the current.  

   • Parallel. There are several roads where the current can circulate.  

In a parallel circuit, the total current in the circuit is the sum of the current in each branch, the voltage in all branches remains constant.

Let's analyze the claims:  

A) False. The bulbs are independent, what happens to one does not affect the other.

B) False. Both bulbs were on, so the second bulb should not be affected.  

C) False. When burn a light bulb, there is more current in the other branch, The opposite happens.  

D) True. When burn a light bulb there is more current in the other branch and therefore the light bulb 2 can dissipate more power by shining a little brighter.

In conclusion, using the characteristics of parallel circuits we can find that the correct answer for the question about what happens when a light bulb burns out is:  

        D) Bulb 2 will stay lit and the light source will be stronger.

Explanation:

The average power  she produces in a day be   97.22 Watts.

The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings. A scalar quantity is power.

Marcia consumes total amount of energy per day = 2000 calories = 8.4 × 10⁶ joule.

1 day = 24 × 60 × 60 second = 86400 second

So, average power  she produces in a day = energy/time

=  8.4 × 10⁶ joule/86400 second
