7 0

Answer:

Their atoms have identical mass.

Explanation:

Oxygen-17 and Oxygen-18 are both isotopes of Oxygen.

Oxygen has three isotopes, Oxygen- 16, Oxygen-17 and Oxygen-18.

Oxygen- 16 has 8 protons and 8 neutrons and a mass number of 16.

Oxygen-17 has 8 protons and 9 neutrons and a mass number of 17.

Oxygen-18 has 8 protons and 10 protons and a mass number of 18.

The three isotopes therefore have the same atomic number ( the number of protons) but different mass numbers.

It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station is constructed as a
Archy [21]

To solve this problem, apply the concepts related to the centripetal acceleration as the equivalent of gravity, and the kinematic equations of linear motion that will relate the speed, the distance traveled and the period of the body to meet the needs given in the problem. Centripetal acceleration is defined as,

a_c = \frac{v^2}{r}

Here,

v = Tangential Velocity

r = Radius

If we rearrange the equation to get the velocity we have,

v = \sqrt{a_c r}

But at this case the centripetal acceleration must be equal to the gravitational at the Earth, then

v = \sqrt{gr}

v = \sqrt{(9.8)(\frac{1000}{2})}

v = 70m/s

The perimeter of the cylinder would be given by,

\phi = 2\pi r

\phi = 2\pi (500m)

\phi = 3141.6m

Therefore now related by kinematic equations of linear motion the speed with the distance traveled and the time we will have to

v = \frac{d}{t} \rightarrow \text{ But here } d = \phi

v = \frac{\phi}{t} \rightarrow t = \frac{\phi}{t}

t = \frac{3141.6}{70m/s}

t = 44.9s

Therefore the period will be 44.9s

The weight of a body in earth is 29N. Find the mass?
maks197457 [2]
Hi!

The weight force is given by: F = mg (mass x gravity)

Then, we have:
29 = m * 9.8
29/9.8 = m
m = 2.95 kg

What about a rubber band, can it change its shape? Is it a solid?
pshichka [43]

Answer:

Yes it is a solid

Explanation:

It just has unusual properties.

Does it float when you drop it? then it is not a gas.

Does it pour into any container as water does? Then it is not a liquid.

So it's a solid.

And it can change it's shape
