Answer:
Option A
Explanation:
The interference color in an oil slick on a puddle results from the interference caused as a result of reflection of light waves from the top as well as from the bottom surface of the oil slick.
This causes a disparity in the path of light reflecting from the surfaces and hence the sunlight is a band of seven colors, i.e., VIBGYOR, the disparities in the path results in constructive interference of the light rays which enables us to see interference colors in an oil slick.
Answer:
Option C=> π+.
Explanation:
Just as it is given in the question above, we can see that the addition or combination of proton and neutron gives what is known as QUARKS.
Quarks are not easily measured because one can not see and study a quark independently; quarks move in multiples together.
The study of Quarks is very important in physics because they relate very well with electromagnetic force, strong force, weak force and Gravitational force.
"...When the remaining quarks combine to form a single particle, it is a π+".
π+ is a meson or a pion and it contains quarks and anti-quarks too
Answer:
The force ratio of a machine is 5 and it velocity ratio is 5 means that the load moved is five times the effort applied and the distance moved by the effort is five times the distance moved by the load at the same time interval.
Explanation:
C . Record the time to complete a chemical reaction
Answer:
This reduces the average force applied during the landing process/ or you can say it reduces the impact your body takes.
