Answer:
the answer is According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge. The electrons are like plums in a pudding.
Explanation:
The pudding represents the positive charge in the plum pudding model of the atom, while the plums represent the negative charge.
What is the plum pudding model?Thomson's atomic model was proposed by J.J. Thomson in 1900. This model described the inner structure of the atom, also known as the plum pudding model.
During the cathode ray tube experiment, J.J. Thomson discovered a negatively charged particle. In the year 1897, he explained that a cathode ray tube is a vacuum tube and the negative particle was called an electron.
Thomson assumed that an atom is made up of thousands of electrons and an electron is two thousand times lighter than a proton. He considered atoms surrounded by a cloud to have positive and negative charges. Thomson’s model of an atom is quite similar to a plum pudding.
According to Thomson’s atomic model, an atom contains a positively charged sphere with electrons embedded in it. The negative and positive charges are equal in magnitude so the whole atom is electrically neutral.

At the atomic level, are synthetic medicines different from natural medicines? Explain your answer.
Answer:
Although herbal medicines are less potent in comparison to synthetic drugs in some cases but still these are consider less toxic or having less side effect in contrast to synthetic drugs. The ultimate norm for any medicine (human made or natural) is their non-toxicity, effectiveness, specificity, stability and potency.

John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it have taken? (In seconds)
Answer:
36
Explanation:
It would have taken 36 s for John to cover the distance.
Average speed is defined as the total distance travelled divided by the total time taken.
Average speed = Total distance / total timeTo obtain the answer to the question, we'll begin by calculating the time taken to cover the distance (3150 m) in each case.
Case 1:Average speed = 350 m/min
Total Distance = 3150 m
Time 1 =?Average speed = Total distance / total time
350 = 3150 / Time 1
Cross multiply
350 × Time 1 = 3150
Divide both side by 350
Time 1 = 3150 / 350
Time 1 = 9 mins
Multiply by 60 to express in seconds
Time 1 = 9 × 60
Time 1 = 540 sCase 2:Average speed = 375 m/min
Total Distance = 3150 m
Time 2 =?Average speed = Total distance / total time
375 = 3150 / Time 2
Cross multiply
375 × Time 2 = 3150
Divide both side by 375
Time 2 = 3150 / 375
Time 2 = 8.4 mins
Multiply by 60 to express in seconds
Time 2 = 8.4 × 60
Time 2 = 504 sFinally, we shall determine how much sooner it would have taken John to travel at 375 m/min. This can be obtained as follow:
Time 1 = 540 s
Time 2 = 504 s
Difference in Time =?Difference = Time 1 – Time 2
Difference in time = 540 – 504
Difference in time = 36 sTherefore, it would have taken John 36 s if he had travelled at an average speed of 375 m/min.

Newtons. With what force does the scale push back up against her feet?
Answer:
The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.
