Answer:
Explained
Explanation:
Displacement is the change in the position of an object with reference to a starting point. for displacement to occur the position of the object must change.
Here the bacteria although moving but it is moving back and forth, meaning its initial and final positions are the same and hence no displacement. Whereas distance is the total distance traveled no matter in what direction. Hence, The total distance traveled by a bacterium is large for its size, while its displacement is small.
Answer:
a)
The distance between planet and the sun is more that is only gravitational force will act between them.
The gravitational force which act between two planet.
b)
When a car going around a friction force act on the car towards the center.
c)
When the rock at the highest position the tension and gravitational force will act.
d)
The wall of the dryer will apply the normal force.
So we want to know how can we detect infrared rays without an instrument. Infrared rays or heat, are a part of electromagnetic spectrum. We have specialized nerve cells in our skin called thermoreceptors that can detect differences in temperature that are produced by infrared part of EM spectrum.
True. If a medium such as H2O is in ice form, sound can not pass through it as well as if it were water or water vapor
