Answer:
a.Distance = 150 m
b. Displacement = 50 m
Time lapsed = 5 seconds
Explanation:
a. Distance is the change in the position of an object.
The distance covered by the car = 100 + 50
= 150 m
b. Since displacement is a vector quantity,
Displacement of the car = 100 - 50
= 50 m due east
c. Time elapsed is the time taken for the motion of the car starting from when its starts to when it stops.
Thus, the time elapsed = 4 + 1
= 5 seconds
Answer:
Interference
Explanation:
When two waves of same frequency and constant phase difference super impose at a point on the screen then due to their superposition we will get different intensity of light at different positions of the screen
This phenomenon of redistribution of energy is known as interference of light.
So at the position of screen where the light intensity is maximum on the screen is known as constructive interference while the positions on the screen where it will get minimum intensity on the screen is known as destructive interference of the light
So correct answer would be
Interference
D) all of the above is the answer
The biomass energy can use improve water quality in soil erosion and sedimentation are decreased during biomass crop growth. The correct option is C.
<h3>What is biomass energy?</h3>
Biomass energy is obtained by the processing of the dead plants and animal or vegetable, cow dung or wood.
The biomass energy obtained by these bio things, it is enriched with the nutrients required by the new crop plants to grow effectively.
The biomass energy provides good water quality by soil erosion and sedimentation.
Thus, The correct option is C.
