Answer:
13807.2 J/g°C
Explanation:
I just took the test and got it correct
In my opinion, the answer would be d: a universal language. D would technically be more important because there are so many foreign scientific companies and to get the information we need to study the universe, we should communicate and give eachother what we have of our resources as we work for it.
Calculate the time it takes for the car to reach the beginning of the hill given that acceleration as already found in part a is 2.89 m/s²
Answer:
5.88 s
Explanation:
Using kinematic equation, v=u+at where v and u are the final and initial velocities respectively, a is acceleration and t is time.
Considering the first part, acceleration is already found as 2.89 m/s and the final velocity is given as 17 m/s while the initial velocity is zero since it is at rest.
Making t the subject of formula then
t=(v-u)/a
Substituting the given figures then
t=(17-0)/2.89=5.8823529411764s
Rounded off, t=5.88 s
Answer:
B. 4a
Explanation:
Force between the charges is inversely proportional to the square of the distance
=> Force will be 4 times and acceleration will be 4a
=> Answer b).
<span>The question is asking us to define the sentence ""I want to run, to skip, and to jump". This is a parallel construction, which means that the three parts ("to run", "to skip" and "to jump" are in the same kind of construction - to <verb>. It could be considered comma splice, but a comma splice would rather be the case if there were different subjects : for example in "I want to run, she wants to skip". </span>
