Answer:
The parachuter is falling at a speed of 31.667 meters per second.
Explanation:
Given that parachuter falls at constant speed and travelled distance and time are known, the unknown is speed, measured in meters per second, which is obtained by the following kinematic expression:
Where:
- Travelled distance, measured in meters.
- Time, measured in seconds.
If 
and 
, the speed of the parachuter is:
The parachuter is falling at a speed of 31.667 meters per second.
Answer:
Second law of motion.
Explanation:
According to second law of motion Force is equals to mass multiplied by acceleration.
Here, Mass is given which is 10 kilograms.
Force is given which is 100 Newton.
So, by putting the values of mass and force in the formula of second law of motion we will get the value of acceleration which is 10 meters per second per second.
Answer:
Electric flux
Explanation:
The electric flux measures the amount of electric field passing through a surface. For any closed surface, the electric field passing through it (electric flux) is given by Guass law. The mathematical relation between electric flux and the enclosed charge is known as Gauss law for the electric field. Electric flux may also be visualised as the amount of electric lines of force passing through an area.
Answer:
The correct answer is b. Differences in Path Lenght
Explanation:
In this area of knowledge, there two main ways of referring to Path Lenght:
1. The total distance an object travels from a starting point, without considering trajectory.
2. When talking about wavelength, because this relates to light and how it travels throughout different mediums. This concept is used in calculating constructive and destructive interference of waves, and is responsible for seeing different shades of tea color.
Hope this helps!
