Preserved fossil<span> (like a fossil in amber, ice or tar.</span>
Answer: Option d.)
R_eq = (1/R_1 + 1/R_2 + 1/R_3)^-1
Explanation:
Since, there are three resistors connected in parallel, the reciprocal of the total resistance of the resistor combination (R_eq) is obtained by adding the reciprocal of each resistance.
i.e 1/R_eq = (1/R_1 + 1/R_2 + 1/R_3)
So, R_eq = (1/R_1 + 1/R_2 + 1/R_3)^-1
Thus, the total resistance (R_eq) is equal to the inverse of the sum of the reciprocal of each resistance.
Answer:
gravitational potential energy
<span>An automobile with a mass of 1450 kg is parked on a moving flatbed railcar; the flatbed is 1.5 m above the ground. The railcar has a mass of 38,500 kg and is moving to the right at a constant speed of 8.7 m/s on a frictionless rail...

Answer:
Induced EMF,
Explanation:
Given that,
Radius of the circular loop, r = 5 cm = 0.05 m
Time, t = 0.0548 s
Initial magnetic field, 
Final magnetic field, 
The expression for the induced emf is given by :

= magnetic flux





So, the induced emf in the loop is 0.0143 volts. Hence, this is the required solution.
