Task #1: Poison ivy is a weed that grows in New York State. It’s synthesizes an oil, urushiol, that causes skin rashes. Researchers have found that if poison ivy grows in an environment that contains an increased concentration of carbon dioxide, the plants grow larger, faster, and produce more urushiol. Because carbon dioxide levels in the atmosphere are rising, poison ivy might become a hazard to people who work or vacation outdoors. In order to verify this research, experiments must be carried out. Design an experiment to test whether poison ivy is affected by air containing higher than normal concentrations of carbon dioxide.
State one way the control group should be treated differently from the experimental group.
Answer:
MEN: accidental injuries, alcohol, diabetes, depression, liver disease, unintentional injuries or/and accidents, skin cancer, smoking, high blood pressure, and heart disease.
WOMEN: heart disease, breast cancer, depression, anxiety, pregnancy issues, high cholesterol.
Answer:
The final energy will be halved of the original energy.
Explanation:
As we know that the capacitance,
C = εA/d
C = capacitance
A = area of plate
d = distance or separation between the plates
ε = permitivity of dielectric material
As you can see from the formula that the capacitance ( ability of the capacitor to store charge) is inversaly proportional to the separation of the plates. If all the other factors kept constant then increasing the distance between the plates will decrease the ability of the capacitor to store energy. So we can say that by doubling the separation, the capacitance or energy stored will become half.
The more resistance you have the more you
have to push to make a current flow
