Answer:
show the atomic number and atomic mass of cesium in your options
Answer:
He could have shut off the power first and de-energize the circuits in order to prevent being electrocuted.
Explanation:
Electrical Safety is very important, <em>especially for those working in such hazardous situations. </em>Almost all our things in the society are electrically-operated, thus it even becomes relevant to have an idea on how we can prevent from obtaining an electrical shock or burns due to faulty electrical tools.
In the worker's scenario above, it is clear that he did not shut off the power at the circuit breaker panel. This is the most important thing that one must include in his plan when attempting to correct an electrical problem. You must find where the electrical switch, fuses and circuit breakers are at first. Once you find their location, you have to turn them off (even if the circuits are of low-voltage).<u> In order to make sure that they are really turned off, test the circuits first. This will help you ensure that they are, indeed, de-energized.</u>
The correct answer to what additional measurement the student requires is; D. The student has enough information to make the determination
<h3>Understanding Change in Momentum</h3>
Formula for change in momentum is;
ΔP = m(v - u)
Now, this change in momentum is also equal to impulse which has the formula; Impulse = Force(F) × Time(t)
I = F × t
Thus;
m(v - u) = F × t
Now, we are given;
Force exerted on the object and the time interval. Thus;
ΔP = F × t
Thus, the student has enough information to find the change in momentum
The missing options are;
a. The mass of the object.
b. The final speed of the object MOH 5000
c. The distance fallen by the object
d. The student has enough information to make the determination

Answer: C. The melting of an ice cube
Explanation: Just trust!
Answer: .3 or 3/10
Explanation: The probability that her first answer is correct is 2/5. Since she got the first guess correct, now there is only 1 correct answer out of 4. There is a 3/4 chance she will get the next problem wrong
So: 2/5 x 3/4 = .3
