the mass would remain the same and the weight would change. mass defines the actual amount of an object, while weight is the force gravity has on that object. gravity is different on the moon and the earth therefore the weight will change

Answer:

the mass would remain the same and the weight would change

Explanation:

Mass can be thought of as the amount of matter an object has, this quantity is a constant, it will not change even if the rocks are carried to the moon.

What will change is the weight, since it is defined as:

w = mg

where w is the weight, m is the mass and g is the acceleration due to gravity.

We said the mass stays the same, but the acceleration g on the moon will be different (smaller) than the acceleration g on the earth.

So because the weight depends on the acceleration of gravity, if the rocks are taken to the moon where that acceleration is different, the rocks will have a different weight.

So the answer is: the mass would remain the same and the weight would change

What is the connection between electrons and protons
TEA [102]

Answer:

Electrons and protons are connected with one another in term of charge and size.

Explanation:

  • The size of electron and proton is always same in any atom but they possess opposite charge.
  • Electron in any atom carries negative charge where as proton carries the positive charge.
  • In any neutral atom the charge between electron and proton is balanced along with the size.
  • The nucleus of any atom bounds only proton and neutron but the electron is present revolving around the nucleus.

How long would it take a 4,560 watt motor to raise a 166 kg piano to an apartment window
IrinaK [193]

Answer:

Explanation:

We need the power equation here:

P = W/t where W is work and is defined as

W = F*displacement.

Force is a measure in Newtons, which is also weight. We have the mass of the piano, but we need to find the weight:

w = mg so

w = 166(9.8) so

w = 1600N, rounded to the correct number of sig dig. We use that now in the power equation:

4560=\frac{(1600)(15)}{t} and isolating the unknown:

t=\frac{(1600)(15)}{4560} so

t = 5.3 seconds

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.59 times a second. A tack is stuck in the tire a
Vesna [10]

Answer:

Tangential speed=5.4 m/s

Radial acceleration=88.6m/s^2

Explanation:

We are given that

Angular speed=2.59 rev/s

We know that

1 revolution=2\pi rad

2.59 rev=2\pi\times 2.59=5.18\pi=5.18\times 3.14=16.27 rad/s

By using \pi=3.14

Angular velocity=\omega=16.27rad/s

Distance from axis=r=0.329 m

Tangential speed=r\omega=16.27\times 0.329=5.4m/s

Radial acceleration=\frac{v^2}{r}

Radial acceleration=\frac{(5.4)^2}{0.329}=88.6m/s^2
