Answer: 20.73 m/s
Explanation:
The centripetal force is given by the following equation:
(1)
Where:
is the centripetal force
is the mass of the car
is the centripetal acceleration
Isolating :
(2)
(3)
(4)
Now, there is a relation between the centripetal acceleration and the tangential velocity:
(5)
Where is the tangential velocity and is the radius of the circular path, which can be found if we know its length :
(6)
(7)
(8)
(9)
Substituting (4) and (8) in (5)
(5)
Finding :
Sensory nerves detect senses like touch, see, smell stuff like that. Motor nerves gives the reaction from the brain after receiving the information from the sensory nerves. example of when you touch a hot water your sensory nerves brings the information and your react to by pulling your hand out of the water. hope it helps
<span> most importantly, the sun is reflected back at the same angle as the angle of incidence, so with vertical panes of glass and the sun overhead, the reflection will just hit the ground before traveling any distance. </span>
Star Wars uses science and technology<span> in its settings and storylines, although its main focus is not necessarily on science. The component of the Star Wars movies which is possible according to our current understanding of physics is their interstellar travel.
</span><span>The behavior of spacecraft engaged in battle is another aspect of the films is troubling the scientists. According to them, when hit in space by a blaster, the crafts should continue moving in the same direction as the impact rather than falling downwards as the effects of gravity would not apply while in orbit. </span>
Answer:
A. Hydrogen bonding between water molecules.
Explanation:
Specific heat capacity of water can be defined as the amount of heat a gram of water must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C). Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.
Cohesion is a property of water and typically refers to the attraction between molecules of water which holds them together.
The high specific heat and cohesive forces characteristic of water are a result of hydrogen bonding between water molecules. A hydrogen bond is formed in water due to its polarity (opposite charges between water molecules), which causes each water molecule to attract other water molecules. An atom of hydrogen of each water molecule bonds with the electron lone pair on atom of oxygen of a close water molecule.
