No it shouldn't, a hypothesis doesn't need to be correct but must have an idea for why x variable effects y variable and have good reasoning. In the conclusion you should state if it's correct or not and explain why it's correct/incorrect and what answer you've determined from data.
Explanation:
Resistors can be connected in two ways;
1. Series connection
2. Parallel connection
When resistors are connected in series, the effective resistance is simply by adding up Rtotal = R1 + R2 + R3...
But when the are connected in parallel the effective resistance is simply 1/Rt = 1/R1 + 1/R2 + 1/R3
You can choose any value for your R1, R2 and R3 try it and see for yourself.
Good luck
Answer: true
Explanation: I got the question and guessed true and it was right
mass lol ion kno man can i have the answer choices
Answer:
Explanation:
Impulse on an object is given by .
However, it's also given as change in momentum (impulse-momentum theorem).
Therefore, we can set the change in momentum equal to the former formula for impulse:
.
Momentum is given by . Because the truck's mass is maintained, only it's velocity is changing. Since the truck is being slowed from 26.0 m/s to 18.0 m/s, it's change in velocity is 8.0 m/s. Therefore, it's change in momentum is:
.
Now we plug in our values and solve:
(two significant figures).
