Answer:
d. NO
Explanation:
As, the potential energy between charge one and two does not depend upon the charge third, so it is very much possible to bring a third charge in from infinity without changing the potential energy of the system. And it does not matter what the sign of the third charge it.
Hence, the correct answer is D.
Answer:
The police will cite you for speeding.
Explanation:
To know if the police will cite you for speeding we need to find the average speed (v):
<u>Where:</u>
x(f): is the final distance = 39 mi
x(i): is the initial distance = 0
t(f): is the final time = 53 min = 0.88 h
t(i): is the initial time = 17 min = 0.28 h
Hence, the average speed is:
Therefore, since the limit speed is 60 mph and your speed is 65 mph, the police will cite you for speeding.
I hope it helps you!
Answer:
High-Level Clouds
Cloud types include: cirrus and cirrostratus.
High-level clouds form above 20,000 feet (6,000 meters) and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals. High-level clouds are typically thin and white in appearance, but can appear in a magnificent array of colors when the sun is low on the horizon.
Mid-Level Clouds
Cloud types include: altocumulus, altostratus.
The bases of mid-level clouds typically appear between 6,500 to 20,000 feet (2,000 to 6,000 meters). Because of their lower altitudes, they are composed primarily of water droplets, however, they can also be composed of ice crystals when temperatures are cold enough.
Low-level Clouds
Cloud types include: nimbostratus and stratocumulus.
Low clouds are of mostly composed of water droplets since their bases generally lie below 6,500 feet (2,000 meters). However, when temperatures are cold enough, these clouds may also contain ice particles and snow.
Answer:
Part a)
so here the angle made by the string is independent of the mass
Part b)
Explanation:
Part a)
Let the string makes some angle with the vertical so we have force equation given as
so we will have
so here the angle made by the string is independent of the mass
Part b)
Now from above equation if we know that angle made by the string is
so we will have
