I'd say B.) Increasing the voltage of the battery.
Answer:
size of insect = wavelength = 16.1 mm
Explanation:
Since the bat can detect the size of small insects which are of size equal to the wavelength of sound in air
So here we can say that the wavelength of sound is the ratio of speed of sound and its frequency
here we know that
speed of sound in air is 536 m/s
frequency of sound is 33.3 kHz
so here we can say
Answer:
1.a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
2.The Eye of a Hurricane. The eye is the region at the center of the hurricane, which is roughly circular in shape and usually has calm weather.
3.Hurricanes form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.
4.When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.
5.a rising of the sea as a result of atmospheric pressure changes and wind associated with a storm.
6.A hurricane dies down when it loses its energy source, which is usually warm water at the surface of the ocean.
7.Hurricane Katrina was so destructive because of a bunch of events that happened in just the right way. First, understand that Katrina was at one point a Category 5 storm and was predicted to hit New Orleans as a Category 4. It weakened to a Cat 3 and veered ever so slightly to the east, making the damage far less than it could have been.

Answer:
The sphere returns back to the neutral.
Explanation:
When a positively charged rod is brought near the far end of the rod A a redistribution of the charges occurs in the rod A. The free electrons in the rod A are attracted towards the positively charged rod. This causes positive charges to be shifted towards the other end of the rod A. The sphere B is in contact with the positively charged end of rod A. So it also acquires a positive charge.
When the positively charged rod is removed from the faf end of rod A, the electrons return to their original state and the charges redistributes themselves and a neutral state is re-established .
