Answer:
226 Per/ deg c
Explanation:
We know that
Here
R1 = Resistance at the room temperature
= 95 ohms
Rt= Resistance of the final temperature
= 115 ohms
T1 = Temperature coefficient
Putting these value in the previous equation we get
T1=226 per Deg C
Answer:
Explanation:
Given
Distance between Pluto and sun is 39.1 times more than the distance between earth and sun
According to Kepler's Law
where k=constant
T=time period
R=Radius of orbit
Suppose is the radius of orbit of earth and sun
so Distance between Pluto and sun is
and is the time period corresponding to and R_2[/tex]
divide 1 and 2
Answer: B. The particles that make up material B are more closely packed together than apart because that make up material A!!!
If there is no input to the system and no leaks from it, then the matter and energy in the system naturally does not change over time
Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field.
Electromagnetic induction has found many applications in technology, including electrical components such as inductors and transformers, and devices such as electric motors and generators.
Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four Maxwell's equations in James Clerk Maxwell's theory of electromagnetism.
