Answer:
just put the molecules and atoms where they belong
Explanation:
Is that a question? If it is not what its the question?
Compared to the pucks given, the pair of pucks will rotate at the same rate.
Answer: Option A
<u>Explanation:</u>
The law of conservation of the angular momentum expresses that when no outer torque follows upon an article, no difference in angular momentum will happen. At the point when an item is turning in a shut framework and no outside torques are applied to it, it will have no change in angular momentum.
The conservation of the angular momentum clarifies the angular quickening of an ice skater as she brings her arms and legs near the vertical rotate of revolution. In the event, that the net torque is zero, at that point angular momentum is steady or saved.
By twice the mass yet keeping the speeds unaltered, also twice the angular momentum's to the two-puck framework. Be that as it may, we likewise double the moment of inertia. Since
, the turning rate of the two-puck framework must stay unaltered.
The density of an object can be calculated using the formula Density = Mass/Volume.
Experimental Density:
Density = 153.8g / 20.00 cm^3
Density = 7.69g/cm^3
Percent error equation:
% Error = | Theoretical Value - Experimental Value|/Theoretical Value * 100
% Error = | 7.87g/cm^3 - 7.69g/cm^3|/7.87g/cm^3 * 100
% Error = 2.29%
Therefore a is the correct answer.
<span>1. Plasma membrane - also known as cell membrane. It is 'the skin of a cell', which acts as a physically controlling barrier for the entrance and exit of materials. It's made up of proteins and lipids.
2. Cytoplasm - everything inside the cell (but not including the nucleus). Much of the cytoplasm is a transparent and gel-like material known as cytosol; cell structures are suspended in it.
3. Ribosomes - these are organelles that are in charge of making proteins.
<span>4. DNA - Molecules containing the genetic code of a cell, which tells the cell what to do. It is located in the nucleus for eukaryotic cells; for prokaryotic cells, it is located in a part of the cell called the nucleoid.</span></span>
