Answer:
Percentage of copper = 88%
Explanation:
Given data:
Mass of copper = 51.2 g
Mass of tin = 6.84 g
Percentage of copper = ?
Solution:
Formula:
Percentage of copper = mass of copper / total mass × 100
Now we will determine the total mass:
Total mass = mass of copper + mass of tin
Total mass = 51.2 g + 6.84 g
Total mass = 58.04 g
Now we will calculate the percentage of copper.
Percentage of copper = 51.2 g / 58.04 g × 100
Percentage of copper = 0.88 × 100
Percentage of copper = 88%
Decreasing the separation between the two magnets will result in increase in the magnetic force between two magnets.
<h3>What is a Magnet?</h3>
This is referred to a substance which produces magnetic field and result in the attraction and repulsion of certain types of things.
Increase in the separation will reduce the magnetic force and vice versa which is why option A was chosen.

Answer:
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
Explanation:
When you drop an identical object in different gravitational conditions it will not have a similar acceleration because of the gravity differences.
