Explanation:
Acceleration is the change in speed over a given time period
Answer:
5 x 10^4 N/m^2
Explanation:
Pressure, force and area are related witg the following equation;
Pressure = Force /Area
From the question, we obtained the following information;
Force = 2N
Area = 0.00004m^2
Pressure =?
Pressure = Force /Area
Pressure = 2/0.00004
Pressure = 5 x 10^4N/m^2
Answer: Photoelectric wave
Explanation: Because it represents an interaction between light and matter that describes light as an electromagnetic wave.
Answer:
Option D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.
Explanation:
we know that
To find out the average speed divide the total distance by the total time
Let
d -----> the total distance in meters
t -----> the time in seconds
s ----> the speed in meters per second

Remember that

we have


substitute


<u><em>Find out the average velocity</em></u>
To find out the average velocity divide the displacement) by the time
The displacement is the distance from the start point to the end point regardless of the route
In this problem
The start point is A and the end point is A
so
The displacement is equal to zero
therefore
The average velocity is 0 m/sec
