Answer:
Nystagmus
Explanation:
Nystagmus describes repetitive involuntary eye movements that have a variety of causes, including brain injury, inner ear damage, stroke, substance abuse and metabolic disorders.
Nystagmus can also be congenital, meaning they are present from birth. Early onset nystagmus is much more common than nystagmus acquired in later life. In general, nystagmus is relatively common.
Nystagmus causes eye movements in both horizontal and vertical directions, and is linked with poor vision and depth perception, and can cause dizziness and disorientation.
Answer:
water's high heat of vaporization
Explanation:
Water is a substance with a high heat of vaporization (2257 J/g). This means that 1 g of water evaporates, a large amount of heat is absorbed.
The mechanism of evaporation is used by the dog to cool their temperature, by panting. In fact, sweat accumulates on their tongue, then the molecules of water with higher kinetic energies evaporates, turning from liquid into gas, While doing so, they absorb a large amount of heat from the dog's body (thanks to the high heat of vaporization of water), allowing the animal to lower its temperature much efficiently.
Answer:D.
The force and displacement are in the same direction
Explanation:for work to be done,force and displacement must be in the same direction
Answer:velocity=5.8m/s
Explanation:
Mass(m)=30kg
Kinetic energy(ke)=500joule
velocity=√(2ke ➗ m)
Velocity=√(2(500) ➗ 30)
Velocity=√(1000 ➗ 30)
Velocity=√(100/3)
velocity=5.8m/s
Answer:
F = 53153.36[N]
Explanation:
In order to solve this problem, we must first use the principle of conservation of energy which is transformed from potential energy to kinetic, in this way we can determine the velocity at which the person enters the water.
where:
m = mass = 100 [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 9 [m]
v = velocity [m/s]
Now replacing we can determinate the velocity.
Then we can calculate the momentum which can be calculated as the product of force by time, this momentum is also equal to the product of mass by velocity.
Now replacing:
F = impact force [N]
t = time = 0.025 [s]
m = 100 [kg]
v = velocity = 13.28 [m/s]
