What does it mean if an experiment is replicable? Why is it important that experiments be replicated?

Answers

Answer 1
Answer: If an experiment is replicable it means that the conduction of the experiment can be done multiple times to obtain data and or results. It is important that experiments be replicated because to basically avoid error in obtaining data. And to make sure a particular set of results aren't because of chance or error in measurement or analysis.

What are the factors that make florida susceptible to hurricanes.?

Answers

Explanation:

1. Location.

Hurricanes are defined as severe tropical storms that form over warm ocean waters starting as storms in the Caribbean(North American continent) or off the west coast of Africa. As the storms drift slowly westward, they gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power.

Warm, moist air moves toward the center of the storm and spirals upward. Hurricanes rotate in a counter-clockwise direction around an “eye.”

2.

It is low lying. Majority of their lands are just a few feet above sea level.

3. Most of the infrastructures are built on rocks that are permeable to water. Hence, water bubble or seep out in unexpected places. Building of sea walls and other barriers to prevent rising seas, storms etc.

The picture above shows 3 sets of balloons, all with a particular charge. Which of the picture(s) is true? Explain. Then explain why the other 2 pictures are incorrect. Make sure to explain all 3 sets.

Answers

Among all of the others Picture 3 is correct.

We know, Like charges repel each other whereas unlike charges attract each other, In picture 3 they are like charges (both are positive) so, we can repulsion hence, picture is correct!

In picture 1, they are unlike charges, & showing repulsion which is wrong, same In picture 2, they are like charges & showing attraction so they are wrong as well

Hope this helps!
C is correct because they would repel each other A is wrong be they wouldn't repel And B is wrong because they shouldn't be repelling each other

A 6kg object has 350j of kinetic energy. find the velocity of the object?

Answers


We have no information describing the direction in which
the object is moving, so we're in no position to discuss its
velocity.   ==> We have only speed to work with.

                                      Kinetic energy = (1/2) (mass) (speed²)

                                                   (350 J) = (1/2) (6 kg) (speed²)

Divide each side by  3 kg :    (350J / 3 kg)  =  (speed²)

Take the square root of each side:       Speed  =  10.8 m/s  (rounded)


Units (for the curious/inquisitive):

[Energy] = [work] =        [force] x                [distance]

                             = [mass-distance/time²] x [distance]

                             =  [ kg-meter / sec² ]  x  [ meter ]

                             =  [ kg-meter² / sec² ]  =  Joule

Energy / mass  =  Joule/kg  =  [ meter² / sec² ]  =  (speed²)

   

Why is ambulance written laterally inverted on the front of an ambulance van

Answers

Answer: So if you are looking in your mirror in the car, you will clearly see what the vehicle is.

Explanation: When there are flashing lights and noises coming from behind you in a car, your first response is going to be checking your mirrors. When you look at the inverted "ambulance" you will see it correctly.

The resultant vector of two particular displacement vectors does not equal the sum of the magnitudes of the individual vectors.Decribe the directions of the two vectors

Answers

If the resultant magnitude of the sum of two vectors is not
the sum of their individual magnitudes, then they are not both
acting in the same direction. 

That's all you really know about them.  They can be in ANY two
different directions; just not both in the same direction. 

If they were both in the same direction, then the magnitude of
their vector sum would be the sum of their magnitudes, and
the direction of their vector sum would be the same direction
as both of them.

Which of the following is a circuit component whose function includes changing an open circuit to a closed circuit?A. wire
B. switch
C. power source
D. load

Answers

Answer:

B. Switch

Explanation:

A device designed to open or close a circuit under controlled conditions is called a switch. The terms “open” and “closed” refer to switches as well as entire circuits. An open switch is one without continuity: current cannot flow through it.

Hope this helps! Please consider marking brainliest!!

the answer is B. Switch
