Answer:
The 40g mass will be attached at 69 cm
Explanation:
First, make a sketch of the meterstick with the masses placed on it;
--------------------------------------------------------------------------
↓ Δ ↓
20 g.................50 cm.................40g
38 cm y cm
Apply principle of moment;
sum of clockwise moment = sum of anticlockwise moment
40y = 20 (38)
40y = 760
y = 760 / 40
y = 19 cm
Therefore, the 40g mass will be attached at 50cm + 19cm = 69 cm
12cm 50 cm 69cm
--------------------------------------------------------------------------
↓ Δ ↓
20 g.................50 cm.................40g
38 cm 19 cm
Answer:
metamorphic rock
Explanation:
Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.
Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.
- At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks.
- These changed rocks have different mineral facies that are different from those of the prolith.
Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.
A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a transformer.
<h3>Which device uses electromagnetic induction to transfer electrical energy from one circuit to another?</h3>
- A transformer is an electrical device that transfers energy from one electric circuit to another using the electromagnetic induction principle.
- It is intended to change the AC voltage between the circuits while keeping the current's frequency constant.
- A transformer work on the principle of electromagnetic induction in which flux is linked from primary to secondary.
- Transformers accomplish this without establishing a conductive link between the two circuits. This is made feasible by using Faraday's Law of Induction, which explains how an electric circuit will interact with a magnetic field to produce an electromotive force (EMF).

Boyle's law states that in an ideal gas system, pressure and volume have an inverse relationship when the temperature remains constant. So B.
Answer:
Cause you are their family and they need you. Do you wanna be someone who abandoned them or be the one they look to and dont dislike into adulthood. Also you signed onto this job no one said it was going to be easy but you making your life easier but harder for someone who is just a kid who still needs you.
