<span>To find the amount of work done by a force acting on a moving object, we can use this simple equation:
W = F * d * cos(theta)
W is Work
F is the force
d is the distance the object moves
theta is the angle between the force vector and the direction of motion
We know that (F * d) is 190 joules. We can find the work done when the angle is 56°.
W = F * d * cos(theta)
W = (190 J) * cos(56°)
W = 106 J
At an angle of 56°, the work done by the force is 106 joules.</span>
Answer:
Explanation:
he answer is 540 because you need to do the area of the wall times six. 15 times 6 times 6 equals 540
The global warming is because of the car pollution was the fire in the forest it makes the air one and the warm air grocery Pacific side which makes me glacier it mostly glacier and breaks down two bases and the rising of the water makes the global warming too much so people are trying to use this card and try to use cycles because of global warming .
l hope it helps you bro
Testable: Able to be tested or tried.
<em>ex. An example of a testable hypothesis is, Students who attend class more have higher grades, while those who skip have lower grades. </em>
Data: Data is the items of information that represent our analyze, or our findings in an experiment.
<em>ex. An example of Data, is the results of information collected for a research paper.</em>
Evidence: Evidence is information that helps show whether a proposed idea is valid.
<em>ex. We can use evidence to help support our point and strengthen our findings with reasoning.</em>
Theory: Theory is an explanation of something in the natural world that can be tested and gives us the same results each time. A proven hypothesis.
<em>ex. Examples of scientific theories are gravitation, evolution, and plate tectonics. </em>
Hypothesis: A hypothesis is a theory or question that can be tested through study and experimentation. It has more reasoning to it than a simple guess, but not enough information to be a theory.
<em>ex. An example of a possible hypothesis is, If we play music while working on homework, the participant's perfomance will increase.</em>
since both components, length and time, are measurable
<span>since Rate = length ÷ time </span>
<span>∴ rate is also measurable and ∴ quantitative.
