Clear question is;
An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?
Answer:
Physical change.
Explanation:
There are two type of changes called physical change and chemical change.
In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.
Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.
Answer: C) Sacral nerve stimulation
Explanation: interstitial cystitis can be simply refered to as a non infectious painful bladder condition which may be chronic depending on the severity. Some of the symptoms include pelvic and bladder pain as well as an urge to frequently urinate.
The best treatment that Allison's doctor is likely to recommend to her is the sacral nerve stimulation. Reducing the urgency to urinate which is associated with interstitial cystitis is the main target of this nerve stimulation technique, it involves simulating the sacral nerves which are the primary link between the spinal cord and nerves in the bladder. In this technique, electrical impulses are sent to the bladder by a thin wire which will be placed near the sacral nerves, this will help to reduce some of the symptoms.
More work is done when one man lifts the weight using a pulley. Option C is correct.
<h3>What is mechanical advantage ?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of forces in levers and pulley.
It is an effective way of amplify the force in simple machines like lever The theoretical mechanical advantage is defined as the ratio of the force responsible for the useful work in the system to the applied force.
More work is done when one man lifts the weight using a pulley. With the pulley, the mechanical advantage is increasing.
Hence, option C is correct.
