Answer:
the previous correct answer is b
Explanation:
When the circuit is closed in the system, a current is induced that follows the lenz law, which opposes the change that is occurring and therefore the coil increases and the idicidal current in the ring must reach the maximum oppositing is the current of the coil, so quiet force is repulsion
Consequently, the previous correct answer is b
Clear question is;
An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?
Answer:
Physical change.
Explanation:
There are two type of changes called physical change and chemical change.
In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.
Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.
The warm air gets pushed up, this also could cause rain, and possibly high winds that can cause a tornado to form
<h3>Answer: </h3>
(a)
<h3>Explanation </h3>
- Newtons First Law can be written as the formula
since acceleration is the changing of velocity as its formula is
Thus, a force must be acting on an accelerating/decelerating object
- It is not mass as the mass does not act on the object but rather the mass is acting on the surface of the ground.
- Changing velocity is already acceleration
- inertia is the term used to describe Newtons first law
