Answer:
Part a)
Part b)
Explanation:
As we know that magnetic flux through the loop is given as
now we have
now rate of change in flux is given as
now we know that
Now plug in all data
Part b)
Now the radius of the loop after t = 1 s
Now plug in data in above equation
On December 7th, 1941, Pearl Harbor was attacked by Japanese forces. The next day, Franklin D. Roosevelt addressed the United States Congress with his memorable “a date which will live in infamy” speech.This speech had two purposes:To rally the American people to support the war effort.
The given terms are :
Current = 0.8 Amperes
Time = 3 minutes = 3 × 60 = 180 seconds
we know that,
now, let's solve for charge (q) :
Total Charge (q) = 144 Coulombs
Answer:
class
Explanation:
An examination of a tool mark is essential when it comes to "Criminalistics" <em>(the study of physical evidence in a crime). </em>It allows the forensic investigator to know what kind of tool was used in the crime scene. There are only two kinds of characteristics of tool marks and these are: individual and class. <em>Striated and molded are types of tool marks. </em>They are not characteristics.
The "class" characteristic of a tool mark allows the investigator to know the <u>shape of tool, its dimensions and its type</u>. However, <em>it doesn't point to the exact tool that was used, </em>but it gives him an idea how the mark was actually created.
Answer:
The two space stations are 644.1653 miles far apart.
Explanation:
The distance of Huston and the International Space Station is 323 miles.
The distance of Huston and the Chinese space station Tiangong is 462 miles.
Angle between the two stations = 109⁰
So, applying the law of cosines as;
c² = a² + b² - 2abcosC
From the picture shown below, a = 323 miles and b = 462 miles
So,
c² = 323² + 462² + 2(323)(462)cos109 = 104329 + 213444 - 298452cos109
cos109 = -0.3256
So,
c² = 414948.9712
<u>c = 644.1653 miles</u>
