Answer:
Cerebrospinal fluid (CSF) is a clear fluid that surrounds the brain and spinal cord.
The answer is definitely letter C. They are both located in the nucleus. Their summation define the mass of one (1) atomic mass unit of a particular element. For example, for carbon atom it has 6 protons and 6 neutrons. Therefore the atomic mass of carbon is 12.
Kinetic energy as she hits the water is 3300 joule.
To find the answer, we need to know about the Newton's equation of motion.
<h3>What's the Newton's equation of motion to determine the final velocity?</h3>
- The final velocity is determined as
V²=U²+2aS
- V= final velocity, U= initial velocity, a= acceleration and S= distance
<h3>What's the final velocity of the driver falling from 3.10m with initial velocity of 6.10m/s?</h3>
- Here, a= 9.8m/s², U= 6.10m/s and S= 3.10m
- So, V²= 6.1²+2×9.8×3.10= 98
- V= √98= 10m/s
<h3>What's the kinetic energy of the driver when touches the water?</h3>
Kinetic energy= 1/2×mass×velocity²
= 1/2 × 66 × 10²
= 3300J
Thus, we can conclude that the kinetic energy of the driver is 3300 Joule.
