Answer:

$force = mass \times acceleration \\ 100 = m \times 5 \\ m = \frac{100}{5} \\ m = 20 \: kg$

You wad up a piece of paper and throw it into the wastebasket. How far will

astraxan [27]

Answer:

Since the paper is wadded up tight, and if there's any

air resistance left we assume there isn't any, it might

just as well be a stone that's tossed. This is just a

stripped down projectile situation.

You said "an angle of 36 degrees", but you didn't say relative

to what. I'll assume that it's 36 degrees above horizontal, and

now I'll proceed to answer the question with the information that

I just gave myself.

-- The vertical component of the velocity is 1.4 sin(36)

= 0.823 m/s up.

-- The projectile rises for (0.823/9.8) second, runs out of gas,

and then falls for another (0.823/9.8) second to its original height.

So it's in the air for

2 (0.823/9.8) = 0.168 second

(not very long at all)

-- The horizontal component of the velocity is 1.4 cos(36)

= 1.133 m/s

and it doesn't change.

-- During the 0.168 second that it's in the air,

the wad travels horizontally

(0.168 s) x (1.133 m/s)

= 0.19 meter

(19 cm, ~ 7.5 inches)

If you find my mistake on this one, please please tell me.

As of now, it looks like with that velocity at that angle, your

paper wad only makes it 7.5 inches from your hand into the can.

Two cubes, one silver and one iron, have the same mass and temperature. A quantity Q of heat is removed from each cube. Which on

scoundrel [369]

Answer:

C) specific heat capacity

Explanation:

As we know that heat given to the system to change the temperature is given as

$Q = ms \Delta T$

here we know that

Q = thermal energy given to the system

s = specific heat capacity of the system

$\Delta T$ = change in temperature

so here we know that

$\Delta T = \frac{Q}{ms}$

here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)

So correct answer would be

C) specific heat capacity

Grilled cheese or Cheese toasty??

LUCKY_DIMON [66]

Answer:

Toasties are British in origin and were usually made in ovens. They were the same as a grilled cheese but the bread was not buttered. Some Brits would make them in a pan in the oven, too, which is even closer to the stove-top grilled cheese.

The diagram below shows some waves traveling along a rope.

Harrizon [31]

-- Well first of all, the waves are transverse waves. The fibers in the rope, and the hand that generates the waves, are moving up and down, but the wave is moving to the right, towards the wall. These directions are perpendicular.

-- Later on, after the waves reflect from the wall and travel back toward the hand, there are going to be standing waves on the rope. But this is probably beyond the scope of the question.

Answer:

1/ How do scientists determine the elements present in different stars?

KEY WORD for the main idea: Analysis of the starlight.

Answer: Scientists can identify what elements present in different stars by analysing the starlight.

Note: The "starlight" = spectral lines. Astronomers can can identify what kinds of stuff are in stars from the lines they find in star's spectrum. From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.

2/ What happens to a star when the fuel for its nuclear fusion reactions is exhausted?

KEY WORD for the main idea: generate light from energy

Answer: A star generates energy through nuclear fusion; this energy is released a light and heat.

Note: The energy source for all stars is nuclear fusion. Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom - plus a lot of energy, which is released as light and heat. A normal star that has exhausted the nuclear fuel in its interior, its outer layers have expanded, and it has become a red giant.

....

3/ Why aren't stars and galaxies spread out evenly across the universe?

KEY WORD for the main idea: Gravitational attraction

Answer: Stars and Galaxies aren't evenly distributed uniformly throughout the universe, because of the existance of gravity.

Note: Gravity, as one of the fundamental forces of the universe, is the powerful force that glues our universe together. This is the one that causes every object in the universe to attract every other object. One of the most noticeable effects of gravity in the solar system is the orbit of the planets.
