The answer is 36 kilometers per hour, or 10 meters per second.
Answer:
High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. Places where the air pressure is high, are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it.

Answer:
a flow of negatively charged electrons is an
electric current
Explanation:
It is given that,
Object distance, u = -3.75 cm (negative always)
Focal length, f = +4 cm
We need to find the angular magnification of the lens. Firstly, we will find the image distance using lens formula as :



v = -60 cm
Angular magnification is as the ratio of image distance to the object distance i.e.


m = +16
So, the angular magnification of the insect is 16. Hence, this is the required solution.
Answer:
b. 40 degrees
Explanation:
Range = (U²Sin2tita)/g
Let's assume a constant velocity of 1 m/s and acceleration of 10 m/s² and try the following angles.
For 10 degree
Range= (sin20)/10
Range = 0.034m
For 40 degrees
Range= sin80/10
Range = 0.098m
For 70 degrees
Range = sin140/10
Range = 0.064
For 90 degrees
Range = sin180/10
Range = 0
Comparing the above result, we can see the degree with the highest range is degree 40.
