Answer:
True
Explanation:
I guess you made a mistake on question.
but I understood what you wanted to say.
Hope this helps... :)
The question is missing the alternatives. Here is the complete question.
Two vectors of magnitude |A| = 8units and |B| = 5units make an angle that can vary from 0° to 180°. The magnitude of the resultant vector A+B CANNOT have the value of:
A. 2 units
B. 5 units
C. 8 units
D. 12 units
Answer: A. 2 units
Explanation: Vector is an entity that has characteristics as magnitude and direction. Resultant vector is the "sum" of 2 or more vectors.
In this question, the vectors have magnitude and angle varies from 0° to 180°.
When angle between vectors A and B is 0°, they are parallel and pointing to the same direction, so:
= 13
When the angle is 180°, it means vectors are in opposing directions, so:
= 3
From the calculations, we can conclude the magnitude of resultant vector varies between 3 and 13.
<u>The least value is 3, so it </u><u>cannot</u><u> have a value of </u><u>2 units</u><u>.</u>
I think B) would be the best answer, mainly because when clouds become congested and compact like that it typically signifies it's going to rain because of condensation. Seeing how B has a ton of clouds packed together, that would be the most likely for it to indicate a future rain storm.
Work with your units:
1 watt-hour = 1 (joule/second) · (hour) = 1 (joule-hour / second)
(1 joule-hour/sec) · (3600 sec/hour) = 3600 joules
So 1 watt-hour = 3,600 joules
