Waters Lower density while in a solid form is due to how the hydrogen bonds are formed as it freezes, water molecules are apart compared to liquid water. The structure of ice makes it less dense than free flowing molecules in the liquid water, giving it the ability to float on water.
Answer:
In this case, the two backward forces (air resistance and friction) perfectly balance the applied force of the wheels on the road in the opposite direction. Now unbalanced, those forces acting backward on the car slow it down, which we also know as negative acceleration
Explanation:

C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.
