The question is incomplete, the complete question is;

Shah did not trust the results of an experiment that she had read about, so she is conducting the experiment herself. She goes through the same set of steps and measures the effect of the amount of sugar on a single organism.

Which best describes what Shah is doing?

replication

repetition

both repetition and replication

neither repetition nor replication

Answer:

replication

Explanation:

Replication in scientific experiments refer to the process of going through all the steps in an experiment in order to obtain the same set of results initially obtained.

All scientific experiments is expected to be replicated under identical experimental conditions. If the results obtained by a scientific investigation cannot be replicated under identical circumstances by other scientists, then the scientific data must be taken with a pinch of salt.

Shah is expected to obtain almost exactly the same data as the original researchers who first published the data.

Which situation is most likely to lead to improving a scientific theory?
Nonamiya [84]

Answer:

A. Repeating an experiment to verify results

Explanation:

A scientific theory may be defined as the theory of science that is a thought out explanation of the observations done in the nature or that happens in the natural world. They are constructed using several scientific methods by observing many facts and hypothesis.

According to the question, repeating of an experiment a number of times and verifying its result may help in improving a scientific theory as if we get the similar result for each experiments, then it confirms the basis of the hypothesis or the facts that are observe in the nature and conclude a scientific theory.

A wooden bucket filled with water has a mass of 68 kg and is attached to a rope that is wound around a cylinder with a radius of
Aleonysh [2.5K]

Answer: 210.2N

Explanation:

Assume a bucket of water with a total mass of 68kg is attached to a rope, which in turn is tied around a 0.078m radius cylinder at the top of a well. A crank with a turning radius of 0.250 m is attached to the end of the cylinder.

the minimum force directed perpendicular to the crank handle required to raise the bucket is

(Assume the rope's mass is negligible, that the cylinder turns on friction-less bearings, and that g = 9.8 m/s2

The crank handle provides a torque T=0.25F where F is the force we are looking for.

A free body diagram will show that the tension in the rope times the cylinder radius R is equal to the torque on the cylinder. But the tension in the rope is just the weight of the bucket

W=mg= 68kg

W(0.078)=T=0.25F

F=0.312W=0.312(68kg)=21.216kg= 210.2N

11111nata11111 [884]
The answer is enthalphy

Enthalphy especially used in thermodynamic system. It itncludes the internal energy which required to create the system and the ammount of energy required to establish its volume and pressure

Real life products of enthalphy applcation are refrigerator and compressor

I need help with the table, which is speed and velocity and acceleration
likoan [24]
The first box is Acceleration
the second box is Speed
the third box is Speed
the fourth box is velocity
the fifth box is Speed.

The reason the first box is acceleration is because let's say you are about to go up a hill you need to add acceleration to make it up the hill, I was going to say speed but it wouldn't said what mph was. 

The reason the second, third,and fifth box is speed is because it is telling up that an object is going _mph (the blank is where you put your estimate of speed of an object). 

The reason the fourth box is velocity is because velocity is both magnitude and direction so in the fourth box it says that the race car made a slight left turn which is a direction that the car is going in. 

Hope this helped :)
Have a great day
