A single coil with a radius of 0.02 m is placed inside a 3m longsolenoid that has 600
turns. The radius of the solenoid is 0.15 m. The plane of the coilis perpendicular to the axis of the solenoid. The solenoid isconnected to a battery, an ammeter and a switch. The ammeterreaches 5A in 0.2 seconds and remains constant. The change in themagnetic flux across the small loop is 1.58 x 10^-6 T.m^2. Theaverage induced emf (voltage) in the small loop is 7.9 x 10^-6 V.Another solenoid has an inductance of 8.000 henries and aresistance of 2.772O. It is connected to a battery and a switch.How long does it take for the current to reach half of its maximumvalue after the switch is closed?

I cannot figure out which equation to used in order to solve this.I know the current must be determined, but I am not sure how to dothat with knowing only the inductance and the resistance. I knowI'm probably over-thinking this, but everything I've tried does notgive the correct answer. Can someone please help me figure thisout?

What will be the nature of an exothermic reaction having negative entropy change?

2. We toss a fair six-sided die twice, and record the number that is showing on each toss.
(a) How many outcomes are there in the sample space?

(b) What is the probability that the die shows 5 at least once?

(c) What is the probability that the die does not show 5?

Choose. Shear and bending miners are assigned sign conventions using the sign convention march the provided statements

Choose neither positive or negative, positive or negative

A 12.5-foot-long, nearsighted python is stretched out perpendicular to a plane mirror, admiring its reflected image. If the greatest distance to which the snake can see clearly is 26.0 ft., how close must its head be to the mirror for it to see a clear image of its tail?

What is python ?

The US economy did recover from the numerous crises of the 1970s to some extent, but the period (1981–now) was very different from the 'golden age' of the 1950s and 1960s. Name and describe a few of the most significant contrasts between these two economic eras (NOT the crisis years of the 1970s) for this task, as well as some of the possible explanations.

In other words, how do these two eras differ from one another, and how can we account for those differences?

Why do most people feel the need to have an answer to everything and not accept “I don’t know”?
