Well water or any liquid actually takes the form of the cup of bowl or whatever you put the liquid in
REMEMBER- Liquid has no shape.
hope this helps!!!!!!!!
Answer:
as an object gains speed it gains kinetic energy
Explanation:
i am mixed with the very first one i dont really know if its right so if its wrong my bad
Answer:

Explanation:
The acceleration of an object is the rate of change of velocity of the object; it is given by:

where
u is the initial velocity of the body
v is its final velocity
t is the time elapsed
In this problem, we have:
u = 5.0 m/s is the initial velocity of the skater
v = 10.0 m/s is the final velocity
t = 5 s is the time elapsed
Therefore, the acceleration of the skater is:

Answer:
Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal.
Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14–16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).

Answer:
0.05 rad/s
Explanation:
7.8 km = 7800 m
For the residents inside the space cylinder to experience the same gravitation acceleration g = 9.81m/s2 on Earth, the centripetal acceleration must be the same as g

But centripetal acceleration is product of angular velocity squared and radius of rotation r
