Answer:
Time = 16.667 seconds
Explanation:
Given the following data;
Distance = 50 meters
Velocity = 3 m/s
To find the time it will take;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Velocity = distance/time
Making time the subject of formula, we have;
Time = distance/velocity
Time = 50/3
Time = 16.667 seconds
C. Forces have mass and take up space
A seesaw is a class 1 lever
Parts:
Load- The force applied to the lever
Fulcrum- in the middle
Effort- what lifts the load
so in a seesaw with 2 people, whoever is using their feet to push the seesaw up is the effort while the other person is the load. This changes depending on who is pushing the seesaw. the joint/thing between the two people is the fulcrum.
The displacement would be the final position (37) minus the initial position (50) if using the displacement formula.
When a light wave encounters an object, they are either transmitted,reflected,absorbed,refracted,diffracted, or scattered depending on the wave
