option D
you compare the data from your experimental results to the prediction being tested
Answer:
1570 V
Explanation:
N = 100
diameter = 2 m
radius = 1 m
B = 5 tesla
initailly the angle between the area vector of the coil and the magnetic field is zero and then the angle becomes 180 degree.
t = 2 s
Let Φ be the initial magnetic flux.
Φ = B A Cos 0 = 5 x 3.14 x 1 x 1 x 1 = 15.7 Wb
Let Φ' be the final magnetic flux
Φ' = B A Cos 180 = - 5 x 3,14 x 1 x 1 x 1 = - 15.7 Wb
According to the law of electromagnetic induction, the induced emf developed is equal to the rate of change of magnetic flux linked with the coil.
Answer:
Humans use water for many different things. We use water to stay hydrated. Our bodies need water to live. Back in the day people used water for transportation and trading. This was a way to become wealthy and exchange goods and ideas from one place to another. We also use water to clean ourselves off. If we don't we can become sick with illnesses that can harm our bodies.

Answer:
Explanation: The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes. People also contribute to changes in the appearance of land.
