Answer:
The corresponding dimensions will be "x = 300 & y = 60".
Explanation:
Available fencing = 600 ft
Fencing,
⇒ 
⇒ 
As we know,
⇒ 
On substituting the given values, we get

...(equation 1)
On differentiating with respect to y, we get
⇒ 




On putting the values of y in equation 1, we get
⇒ 
⇒ 
⇒ 
⇒ 
Dimensions of the rectangular area:
x = 300
y = 60
Answer:
Induced current,
Explanation:
Given that,
Area of cross section of the wire, 
Time, t = 2.2 s
Initial magnetic field,
Final magnetic field,
Resistance of the coil, R = 8 ohms
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.023 volts. The induced current can be calculated using Ohm's law as :




So, the magnitude of the induced current in the loop of wire is
. Hence, this is the required solution.
Answer;
The above statement is true
Human impact on one system leads to changes in more of Earth’s systems.
Explanation;
Events can occur naturally, such as an earthquake or a hurricane, or they can be caused by humans, such as an oil spill or air pollution. An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres.
Human impact on one system leads to changes in more of Earth’s systems because things like carbon and methane emissions affect the environment, which affects all plant and animal life.
