Explanation:
the question it's not complete as I don't know the height as the formula for potential energy is : <u>PE = </u><u>mgh</u>
<em>(m) - mass acceleration due to gravity </em>
<em>(g) - acceleration due to gravity </em><em> </em><em>(</em><em>9</em><em>.</em><em>8</em><em> </em><em>m</em><em>/</em><em>s2</em><em>)</em>
<em>(h) - height</em>
Newton I think. I could be wrong
Atomic number: 6 / the atomic number will always be the amount of electrons an element has
Element: Carbon (C)
Mass: 13 / you can find the mass by adding the protons and neutrons together
Charge: 0 or neutral / if an element has the same number of protons and electrons it will be a neutral charge
Isotope: Carbon-13 / all you do is take the element name and the mass and write the isotope like I did above
I hope this help! If you have any questions feel free to ask
Answer:
5.3 kg
Explanation:
The rope attached to the ceiling has a tension 64 N.
The rope attached to the wall has a tension T.
The rope attached to the block has a tension Mg.
Sum of the forces at the junction in the y direction:
64 sin 55° − Mg = 0
Mg = 64 sin 55°
M = 64 sin 55° / g
M = 64 sin 55° / 9.8
M = 5.3
The mass of the block is 5.3 kg.
Dense substances sink into the earth's core heated earth's interior through friction. Hope this helped!
