Answer: Sometimes people try to use there flashlight but it doesnt turn on they take out there battierise and they rub them together. It doesnt work so they get new battiries
Explanation: please mark me brainlies i have a goal im tryna reach thank you!!
M= Height of image/height of the object
If, M>1, then height of image>height of object.
And therefore, image is larger than the object.
The emf will be induced in anti-clockwise direction.
<u>Explanation</u>
Lenz's law tells us the direction us the direction that the current will flow. It states that the direction is always such that it will oppose the change in flux which produced it. This means that any magnetic field produced by an induced current will be in opposite direction to the change in the original field.
To find the direction of emf, Stretch the forefinger, middle finger and the thumb of the right hand mutually perpendicular to each other. If the force finger points in the direction of the magnetic field, the thumb gives the direction of the motion of the conductor then the middle finger gives the direction of the induced current.
The answer is 15.0N its explained in newtons third law hope this helps:)
Explanation:
A chemical reaction in which heat or energy is released is known as an exothermic reaction.
On the other hand, when two objects are placed together and heat flows from hotter object to colder object then this process is known as conduction. Therefore, energy is dissipated in conduction process.
Since energy released released goes into the atmosphere and is not used anywhere.
Thus, we can conclude that when an exothermic reaction releases thermal energy, this energy is usually not useable to do work and it is dissipated by conduction.
