I can't bear to make you handle anything that makes you so uncomfortable. Please ask your Science teacher to contact me directly for the answers.
Answer:
When you ask a question, only two people can answer. When there are two answers, a little crown should appear at the bottom right hand corner. All you have to do is click the crown and it gives Brainliest. But you can only give it to one person per question
Explanation:
Answer:
The remaining percentage of drug concentration is about 88.7% 2 years after manufacture.
Explanation:
Recall the formula for the decay of a substance at an initial 
concentration at manufacture:
where k is the decay rate (in our case 0.06/year), and t is the elapsed time in years. Therefore, after 2 years since manufacture we have:
This in percent form is 88.7 %. That is, the remaining percentage of drug concentration is about 88.7% 2 years after manufacture.
Explanation:
3 cause the triangle method of addition are connected to tips of one vector
Answer:
D
Explanation:
Ball A is a non positively charged non metal while ball B is metal ball.
Given: The ball B positive charge of small magnitude
To prove: Balls will attract each other
IN this condition because of induction negative charges on the sphere B move to the side closer to sphere A,(induction charging) while the positive charges move to the side further away from sphere A. The polarization of charge on B will cause a greater attractive force than the repulsion of the like charges.
Hence the correct answer will be D .
