If we put a resistor in circuit it will slow the speed of current
Let's check ohms law
- So if resistance is more current is less
#17
Again use ohms law
- Voltage must be increased
Answer:
For the First answer I cant answer it But I can help you :
The solid has constituent particles tightly packed and the lattice vibrations are carried out by them in their fixed position however oscillations take place about their mean position. These vibrations are increased as soon as there is increase in the temperature which eventually leads to the more chaotic motion of the constituents. At a fixed critical point of temperature, the bonds are broken and the constituent particles are spaced apart changing their phase into liquid. When more temperature is increased by gaining heat energy then the liquid changes into gas where the motion of constituent particles moving freely is dominant.
Explanation:
Answer:
A change in color
The formation of a precipitate
A clear liquid becoming cloudy
The formation of bubbles
The formation of smoke
Explanation:
A chemical reaction can be defined as the conversion of reactant into product. The process in which one or more than one substance is converted into one or many different substances.
There are some indications which can provide the evidence that chemical reaction has occurred.
A change in color of the substance, formation or smoke or bubbles. The formation of the precipitate and in case the substance becomes cloudy.
All these evidences show that chemical reaction has occurred.
Answer:
Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load. Efficiency of the pulley is 60%means 40% of the energy is lost in the machine due to the friction
False because they can be really big
sorry for the explanation on how bad it was LOL
