Answer:
B) the law of reflection
Explanation:
When a light ray reflects off a surface, it obeys the law of reflection.
A few definitions before giving the law of reflection:
- The angle of incidence is defined as the angle between the incident ray and the normal to the surface
- The angle of reflection is defined as the angle between the reflected ray and the normal to the surface
The law of reflection states that:
- The angle of incidence is equal to the angle of reflection
- The incident ray and the reflected ray lie both on the same plane.
Answer:
24 metre
Explanation:
From the available information in this question,
The swarm of bees moves at 0.20 per second
If it moves at
O.20 = 1 second,
We have a minute to be = 60 seconds
So in one 1 minute the velocity =
0.20 x 60 seconds
= 12 meters
The 2 minutes = 60 seconds x 2
2 minutes = 120 seconds
120 x 0.20 = 24 meters
So in 2 minutes these swarm of bees are going to travel a distance of 24 metres
Answer:
The magnitude of charge is 
with a positive charge.
Explanation:
Given that,
The potential due to a point charge, 
Distance, d = 15.7 m
The potential due to a point charge is given by :
q is charge
k is electrostatic constant
Here, the potential is positive, then the magnitude of charge is with a positive charge.
Answer:
Different organelles play different roles in the cell — for instance, mitochondria generate energy from food molecules; lysosomes break down and recycle organelles and macromolecules; and the endoplasmic reticulum helps build membranes and transport proteins throughout the cell.
