Answer:
Explanation:
The constant speed means that ball is not experimenting acceleration. This elements is modelled by using the following equation of equilibrium:
Now, the exerted force is:
The volume of a sphere is:
Lastly, the force is calculated:
540 nonlillion
thats a 540 followed by 30 0's
According to Lenz’s law, the induced current itself creates a magnetic field to oppose the change in the external magnetic field.
Using the right hand rule, the clockwise current creates a magnetic field vertically downward.
By Lenz’s law, the created magnetic field points downward in response to...
if the external magnetic field points upward and is increasing in strength...
or points downward and is decreasing in strength.
We are told the external field is increasing in strength, so its direction must be vertically upward.
Answer:
''
Explanation:
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input.
