Answer:
220.7
Explanation:
distance traveled is 1.5*5=7.5m
PE gain is MGH=3*9.81*7.5=220.7
Answer:
A bicycle dynamo is a type of generator attached to a bicycle to produce electricity for the bicycle’s lights. The top of the dynamo touches the tire’s rim, which spins when the bicycle starts moving. Currently, the term dynamo refers to mechanisms that are capable of producing direct current, such as the small devices fitted to bicycles to generate power for the lights.
<h3>___________________________________More Defination :- ______________________________</h3>
Typically, a bicycle dynamo has one or more permanent magnets with coils of wire spinning inside their poles. The device consists of a stationary part called a sator and a rotating part called an armature. When the coil spins in the magnetic field created by the magnets, the magnetic flux begins to change trough the coils, resulting in an electric field that generates the charge carriers through the wire. This process produces an electric current. Small bicycle dynamos attain a low efficiency in converting mechanical motion into electricity. However, there are large machines, such as water wheels, that attain high efficiency under ideal conditions.

Answer:
Oxygen and Hydrogen are the most abundant elements found in living beings because of their combination to form water together that builds the 70% of the living body, oxygen being used in respiration and Hydrogen being used to form other compounds as it has the simplest structure and least requirements to bond with other elements.
Explanation:
To build something, it's is important to start with the simplest formation and proceed to the complex ones. Same case applies on living beings. With the creation of all living bodies, two of the most abundant elements Hydrogen and Oxygen tends to volunteer in the formation of living bodies. Their simplest structure and least requirements to bond easily with other elements also make them suitable for the creation of living bodies.
Hydrogen consisting of only one proton and one neutron, easily collaborates with other elements and forms the complex compounds. Whereas, oxygen being processed under the respiration system, helps in developing important organs and compounds. And, most importantly not to forget point is that they both combine to make the significant compound of the living body i.e water. However, Carbon, Nitrogen and other traces are also present in the living beings but these two serve as the saviors of the war.
Answer:
it is applicable on all bodies having mass and the bodies Will be governed by the same law
5.0j as we know that work is derived as force into displacement so 5*1=5si force will be 5.0j
