I’m pretty sure the answer would be 4.
Decrease. you are adding more Sodium chloride therefore less water will be in the solution
The acute spinal cord injury can result due to a traumatic injury, which can either result in a complete teat known as a transection or may result in a bruise known as a contusion. The spinal cord injury generally occurs in young adults and men.
The transection of the spinal cord may result in areflexia and spinal shock. It can also result in flaccid paralysis of all skeletal muscles, loss of sensation, loss of spinal reflexes, and lack of autonomic function below the level of injury.
Answer:
<em>The correct option is A) Yes, the evidence supports the hypothesis.</em>
Explanation:
In the field of scientific research, a hypothesis can be described as a tentative statement which can either be proved right or wrong based on the results form the experiments we perform.
As the results from the experiment showed that the ball which was thrown from a greater height had a greater speed, hence this means that the evidence from the experiment supported the hypothesis.
Answer is D. Light travels more slowly in Medium A than in Medium B because Medium A is dense.
When light travels from a medium of low refractive index to a medium of high refractive index, it slows down in the latter and bends towards the vertical. The extent to which the light ray bends is directly related to the medium's refractive index (or the optical density).
Lets understand the given passage.
A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.
The light bends more in medium A than medium B. Hence medium A is optical denser than medium B.
