Answer:
A reaction time is something that measures the amount of time for you to respond to a stimulus. For an example the average human reaction time for a visual stimulus is 0.25 seconds, 0.17 seconds for a audio stimulus and 0.15 seconds for a touch stimulus.
Explanation:
Stimulus - A thing or event that evokes a specific functional reaction in an organ or tissue
Answer:
<u>The car's average speed is 32 kilometers per hour</u>
Explanation:
1. Let's review the information given to us to answer the question correctly:
First two hours = 60 kilometers
Next two hours = 68 kilometers
2. What is the car's average speed?
Total distance traveled by the car = 60 + 68
Total distance traveled by the car = 128
Total time of travel = 2 + 2 hours
Total time of travel = 4 hours
Average speed = Total distance/Total time
Replacing with the real values, we have:
Average speed = 128/4
<u>Average speed = 32 kilometers per hour</u>
Answer:
The magnitude of the spring force on the disk at the moment it is released is 13.8 N
Explanation:
Given;
Mass of the disk, m = 1.12 kg
spring constant, k = 230 N/m
extension produced in the spring, x = 6.0 cm
According to Hook's law, the force applied to an elastic material is directly proportional to the extension produced.
F = kx
Where;
K is the spring constant
x is the extension of the spring
F = 230 x 0.06
F = 13.8 N
Therefore, the magnitude of the spring force on the disk at the moment it is released is 13.8 N
Answer:
Total displacement = 0
Explanation:
He lives his front porch and still returns to his front porch.
Now, displacement is a vector quantity and as such, it is the distance between the initial point of movement and the final point of movement.
In this case the initial point is the same as the final point and thus the displacement is zero.
A mechanical wave must have a medium.
