Which human body system is affected by autism

Physics
1 answer:
Leya [2.2K]3 years ago
4 0

Answer:

Explanation:

These cells are distributed throughout the body's systems, such as: Immune System, Central Nervous System, Gastrointestinal system, Neuroendocrine and musculoskeletal systems and others. Consequently Autism has been described as a multi-systemic disorder. Autism impacts many systems in the body, including the metabolic, mitochondrial, immunological, gastrointestinal and the neurological. These systems interact in complex and highly interdependent ways.

On cool spring mornings, veils of fog can often be seen rising above warm lakes and ponds. this type fog is an example of ______
brilliants [131]
<h2>Answer: evaporation</h2>

Explanation:

Evaporation fog occurs when surface air is much colder and relatively less saturated than water. Then, when the water evaporates, it inmediately condenses again in small drops of water that stay suspended very close to this body of water.

In other words: This type of fog occurs when cold air moves over warmer water. And it is this difference in temperature that contributes to the formation of fog over the lakes, especially near the polar regions.

If each of the three rotor helicopter blades is 3.50 m long and has a mass of 120 kg , calculate the moment of inertia of the th
devlian [24]

Answer:

1470kgm²

Explanation:

The formula for expressing the moment of inertial is expressed as;

I = 1/3mr²

m is the mass of the body

r is the radius

Since there are three rotor blades, the moment of inertia will be;

I = 3(1/3mr²)

I = mr²

Given

m = 120kg

r = 3.50m

Required

Moment of inertia

Substitute the given values and get I

I = 120(3.50)²

I = 120(12.25)

I = 1470kgm²

Hence the moment of inertial of the three rotor blades about the axis of rotation is 1470kgm²

At a certain instant, a ball is thrown downward with a velocity of 8.0 m/s from a height of 40 m. At the same instant, another b
maks197457 [2]

Answer:

(a) The two balls collide 2\; \rm s after launch.

(b) The height of the collision is 4\; \rm m.

(Assuming that air resistance is negligible.)

Explanation:

Let vector quantities (displacements, velocities, acceleration, etc.) that point upward be positive. Conversely, let vector quantities that point downward be negative.

The gravitational acceleration of the earth points dowards (towards the ground.) Therefore, the sign of g should be negative. The question states that the magnitude of g\! is 10\; \rm m \cdot s^{-2}. Hence, the signed value of \! g should be \left(-10\; \rm m \cdot s^{-2}\right).

Similarly, the initial velocity of the ball thrown downwards should also be negative: \left(-8.0\; \rm m \cdot s^{-1}\right).

On the other hand, the initial velocity of the ball thrown upwards should be positive: \left(12\; \rm m \cdot s^{-1}\right).

Let v_0 and h_0 denote the initial velocity and height of one such ball. The following SUVAT equation gives the height of that ball at time t:

\displaystyle h(t) = \frac{1}{2}\, g \cdot {t}^{2} + v_0 \cdot t + h_0.

For both balls, g = \left(-10\; \rm m \cdot s^{-2}\right).

For the ball thrown downwards:

  • Initial velocity: v_0 = \left(-8.0\; \rm m \cdot s^{-1}\right).
  • Initial height: h_0 = 40\; \rm m.

\displaystyle  h(t) = -5\, t^{2} + (-8.0)\, t + 40 (where h is in meters and t is in seconds.)

Similarly, for the ball thrown upwards:

  • Initial velocity: v_0 = \left(12\; \rm m \cdot s^{-1}\right).
  • Initial height: h_0 = 0\; \rm m.

\displaystyle  h(t) = -5\, t^{2} + 12\, t (where h is in meters and t is in seconds.)

Equate the two expressions and solve for t:

-5\, t^{2} + (-8.0)\, t + 40 = -5\, t^{2} + 12\, t.

t = 2.

Therefore, the collision takes place 2\, \rm s after launch.

Substitute t = 2 into either of the two original expressions to find the height of collision:

h = -5\times 2^{2} + 12 \times 2 = 4\; \rm m.

In other words, the two balls collide when their height was 4\; \rm m.

olchik [2.2K]

For this case, in the next item we have gravitational potential energy:

An apple in a tree.

Suppose we define our reference system at the floor level.

Suppose the apple is at a height h from the floor and has mass m.

The gravitational potential energy of the apple is given by:

U = mgh

Where,

m: apple mass

h: height of the apple with respect to the floor

g: acceleration due to gravity

Answer:

C) an apple on a tree
