Experiments are often performed in laboratories because of letter b, you can control more variables more easily. It is because you have enough supplies in the laboratory where it is accessible, making it easy to control and to conduct the experiment that is going to be made. For having an accessible and easy control in variables is essential to do because in creating an experiment, a lot of things are needed and used.
<span>The first choice i correct. The second is also correct as it should obey the Law of Conservation of mass. The third choice is incorrect. It depends on the nature of the system. For example, for an ideal gas, you can define at least 2 parameters to set the system boundaries. The fourth choice is incorrect, a system can be theoretical or practical. Hence, the answers are the first and second choices.</span>
Answer:
a)48300 times
b)P = 821100 kg · m/s
Explanation:
Given that
m = 48300 kg
v= 23 m/s
We know that linear momentum (P) given as
P = m v
P = 48300 x 23 kg · m/s
So we can say that truck momentum is 48300 times its velocity.
Now given that
v= 17 m/s
P = m v
P = 48300 x 17 kg · m/s
P = 821100 kg · m/s
The answer is <span>b. False. give the radius, degree of curvature, and length of curve that you would recommend. 3.43 for the h. Give it a try man
