What is difference between atoms and molecules?

Answers

Answer 1

Answer: A molecule is composed of two or more kinds of atoms. That is, the atom is the base material and the molecules are groups of atoms.

Answer 2

Answer:

The difference between atoms and molecules is that atoms has a nucleus that is surrounded by electrons and Molecules are atoms bonded together by single, double or triple the bond.

I have three questions. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bottle, and the bottle flies forward at 25 m/s. How fast is the ball traveling after hitting the bottle? 2. Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of woof is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the woof block move together as one object. How fast are they traveling? 3. A big league hitter attacks a fastball. The ball has a mass of 0.16 kg. It is pitched at 38 m/s. After the player hits the ball, it is now traveling 44 m/s in the opposite direction. The impact lasted 0.002 seconds. How big of a force did the ballplayer put on that ball?

Can somebody please explain to me how the acceleration in simple hormonic motion is proportional to the displacement..

Answers

When you graph simple harmonic motion in an acceleration versus displacement graph, the graph at any point would be linear. The graph would also pass through the origin giving proportionality of acceleration to negative displacement. Definition of proportionality neglects the negative value of the displacement so therefore acceleration is proportional to displacement. The acceleration of the motion is always directed towards equilibrium and so at maximum displacement, there would be greatest negative acceleration and vise versa.At the origin, the displacement would be zero and acceleration would also be zero

Which of the following can be determined by studying the spectrum of a star?the chemicals in the atmosphere of the star
the motion of the star
the temperature of the atmosphere of the star
all of the above

Answers

Answer:

all of the above

Explanation:

The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.

The right answer for the question that is being asked and shown above is that: "all of the above." the following that can be determined by studying the spectrum of a star includes: the chemicals in the atmosphere of the star; the motion of the star; the temperature of the atmosphere of the star.

As more lamps are put into a series circuit, the overall current in the circuit a. Increasesb. Decreasesc. Remains the same

Answers

Answer:

b. Decreases

Explanation:

The total resistance of a series circuit is equal to the sum of the individual resistances:

$R_T=R_1+R_2+...+R_n$ (1)

Therefore, as we add more lamps, the total resistance increases (because we add more positive tems in the sum in eq.(1).

The current in a circuit is given by Ohm's law:

$I=(V)/(R_T)$

where V is the voltage provided by the power source and $R_T$ is the total resistance. We notice that the current, I, is inversely proportional to the total resistance: therefore, when more lamps are added to the series circuit, the total resistance increases, and therefore the current in the circuit decreases.

Light from the Sun takes 8 minutes to reach Earth. How long (in min) does it take to reach Jupiter, 5.2 AU from the Sun? min

Answers

Answer: 43 minutes and 14 seconds.

Explanation:

The speed of light in a vacuum is approximately 186,282 miles per second (299,792 kilometers per second). To find the time it takes for light to travel from the Sun to Jupiter, divide the distance by the speed of light:

Time = (Distance from Sun to Jupiter) / (Speed of Light)

Time = (5.2 AU * 93 million miles/AU) / (186,282 miles/second)

Now, you can calculate the time in seconds and convert it to minutes:

Time = [(5.2 * 93 million miles) / (186,282 miles/second)] * (1 minute / 60 seconds)

Time ≈ [(483.6 million miles) / (186,282 miles/second)] * (1 minute / 60 seconds)

Time ≈ (2594.16 seconds) * (1 minute / 60 seconds)

Time ≈ 43.236 minutes

So, it takes approximately 43.236 minutes for light from the Sun to reach Jupiter, which is about 43 minutes and 14 seconds.
