Answer:
Mg will replace Ag in a compound
Explanation:
A single replacement reaction is driven by the position of ions on the activity series.
As a rule of thumb, the position of metal ions on the activity series determines their reactivity.
Metal ions that are above another are more reactive and they will displace those that are lower.
Generally, activity increases as we go up the group.
Mg ions are higher than Ag ions on the series so, Mg will displace Ag from a solution.
Answer:
The answer is 3.111111.
Explanation:
It runs 28 m in the first 9 s, and 28 divided by 9 equals 3.1 and the one goes on forever.
Gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.
<h3>What is gravitational potential energy?</h3>
The energy that an item has due to its location in a gravitational field is known as gravitational potential energy.
Length of hanging part, L/4
The gravitational potential energy is;
Work = Gravitational potential energy
Work done =force×displacement
Hence, gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.

Answer:
In reality, economics is a vitally important subject because it is the study of making choices. More specifically, it is the study and practice of making choices in a world of limited resources (scarcity). You cannot go for a day without making economic decisions. ... One of these variables is scarcity.

If the mass of one object is doubled, the force between these objects will also double.
Force refers to an influence on a body which can change its state of rest or motion.
Force F = G(mM/d^2) (where m is the mass of first object, M is the mass of the second object and G is the gravitational pull and d is the distance between the two objects)
The force between two objects (m and M) (according to the universal law of gravitation) is proportional to their mass and reciprocally proportional to the square of their separation (R) between them.
So F' = G(2mM/d^2),
which means F'=2F
Therefore, the when the mass is doubled, the force also doubles.
