Which of the following is true of children with chronic illness? a.) They are all eligible to recievie special education service
ss7ja [257]

Answer:

c.) Their eligibility for social education services depends on whether their conditions adversely affect their educational functioning.

Explanation:

Chronic Illness is a human health condition in which a particular (or number of) illness is persistent in the body and the effects on the body are long-lasting and are often resistant to treatment. The word chronic is usually used when the disease/illness/sickness and its effects stay in the body for more than three months.

The likeliest answer from the options given is option C because before social education services are given, it has to be decided if their health condition adversely affects their education.

Even under the most ideal conditions, only about 8% of the internal energy of the steam produced in a steam engine can be conver
Anna71 [15]
As per the law of conservation of energy, no energy is created or destroyed. Therefore, we can conclude that the remaining 92% of energy released in electricity generation from steam power plants is converted to other, non-utilizable forms of energy. Such forms include sound energy or thermal energy between the moving parts of the plant.

A system dissipates 12 J of heat into the surroundings; meanwhile, 28 J of work is done on the system. What is the change of the
timurjin [86]

Answer:

option C

Explanation:

given,

energy dissipated by the system to the surrounding = 12 J

Work done on the system = 28 J

change in internal energy of the system

Δ U = Q - W

system losses energy = - 12 J

work done = -28 J

Δ U = Q - W

Δ U = -12 -(-28)

Δ U = 16 J

hence, the correct answer is option C

A duck waddles 3 meters East and then 4 meters North. What is the magnitude and direction of his displacement?
Nadusha1986 [10]
East is our x axis 
north is out y axis                               N
                                                              |
                                                              |
                                                W _____|_______E
                                                              |
                                                              |
                                                              |
                                                              S
so he moves 3 m to the right and then 4 upwards

imagine what that looks like.......... a right angle triangle 

therefore we can use Pythagorean theorem  
 let the unknown side be x, which is the hypotenuse in this case

x^2 = 3^2 + 4^2 
x^2 = 9 + 16
x^2 = 25
take the square root
x = 5

5 is your magnitude and the direction is NE( North East) or positive direction
