A concussion, which is a form of mild traumatic brain injury, occurs after a blow to the head. The brain is surrounded by fluid and protective membranes called meninges, which usually cushion the brain. During an impact, the brain is pushed against the inside of the skull and can be bruised.
Answer:
v = 1247.92 m/s
Explanation:
The formula for kinetic energy is given as follows:
Another formula that is used for Kinetic Energy is given as:
Comparing both formulae for K.E:
where,
v = rms speed of helium molecule = ?
K = Boltzmann Constant = 1.38 x 10⁻²³ J/k
T = Absolute Temperature = 250 K
m = mass of helium molecule = 6.646 x 10⁻²⁷ kg
Therefore,
<u>v = 1247.92 m/s</u>
Answer:
Elephant and the eath because Fg is determined by Mass of an object.. So elephant has greater mass therefore, it's Fg is higher
Based on the mass it will increase the velocity of how big it is
