The slope of a speed-time graph is the acceleration represented by the graph.
All other parts of this question refer to a lab experiment or exercise
where I was not present, but Zeesam16 was. Therefore I have no data
with which to answer the rest of the question, and hope that Zeesam can
handle it.
Answer:
GFCI outlets are found in wet areas.
GFCI outlets prevent electrocution if you are touching a wet appliance.
Answer:
For the first one c is the answer
For the second one c is also the answer
For the third one is b
Explanation:
I took that
Answer:
momentum =0
kinetic energy >0, positive
Explanation:
The final momentum is zero but the final kinetic energy is positive.
The momentum is zero because momentum is the sum of the mass×velocity for each component. momentum is conserved
The KE is positive because KE is the sum of the 1/2×mass×velocity^2.
Whereas velocity can be positive and negative since it is (it's what makes the momentum zero because on is positive and one is negative), the velocity squared will always be positive.
Adding together two positives will always be a positive number.
This is a bad hypothesis because it's a statement. It is a description of what occurs, not a question that you will experiment upon to find an answer whether or not something will or will not be true.
