Answer:

True.

Explanation:

According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. This statement is true.

The Faraday's law of induction is given by :

\epsilon=-\dfrac{d\phi}{dt}

Here, negative sign shows that the direction of induced emf is such that opposes the changing current that is its cause.

Hence, the statement is true.

On a horizontal axis whose unit is the meter, a linear load ranging from 0 to 1 ma a linear load distribution = 2 nC / m.
Dimas [21]

Answer:

The correct answer is - 8.99N/C

Explanation:

dE=k\dfrac{dq}{x^2}\\ dq=\lambda{dx}\\ \lambda=2nC/m\\ dq=2dxnC\\ dE=k\dfrac{2dx}{x^2}\\ E=2k\int_1^2\dfrac{dx}{x^2}\\ E=2k(\frac{-1}{x})_1^2=k\times10^{-9}N/C\\ E=8.99\times10^9\times10^{-9}N/C\\ E=8.99N/C\\dE=k

Why are cockpits not pressurized
Darina [25.2K]
It be more productive to just have the pilot were an oxygen mask instead of using the entire section for air when the pilot is siting down. The glass may also fog up, causing the entire glass pane to explode at high altitude.

Which statement describes the direction of spontaneous heat flow
NISA [10]
The direction of spontaneous heat flow in a system is described by the second law of thermodynamics, which describes that the direction of spontaneous heat flow is from a region of higher heat energy to a region of lower heat energy.
Multiple statements of this law are available, such as the one presented by Carnot or the one presented by Clausius and Planck.

Why do quarterbacks throw the football with significant spin about its long axis?
Lera25 [3.4K]

(a) the principle of aerodynamic convergence

(b) the centripetal force

(c) Conservation of angular momentum

(d) Conservation of kinetic energy

(e) None of these

Conservation of angular momentum

Answer: Option C.

<u>Explanation:</u>

The law of conservation of angular momentum expresses that when no outer torque follows up on an article, no difference in precise force will happen.

The law of conservation of angular momentum expresses that the angular energy of a body that is the result of its snapshot of latency about the hub of revolution and its rakish speed about a similar pivot, can't change except if an outside torque follows up on the framework.

Help solve these two problems im having trouble trying to start these problems?​
belka [17]

Answer:

25.  Approximately 8.1 meters

26. North 1.31 km, and East 2.81 km

Explanation:

25.

Notice that the displacements: 6 meters east and 5.4 south create the legs of a right angle triangle. The hypotenuse of that triangle will be the distance (d) needed to cover in order to get the ball in the hole in one putt. That is:

d=\sqrt{6^2+5.4^2} =\sqrt{65.16} \approx 8.072\,\,\,m

which can be rounded to 8.1 m.

26.

Notice that the 3.1 km at an angle of 25 degrees north of east, is the hypotenuse of a right angle triangle that has for legs the east and north components of that distance.

We can find the leg corresponding to the east displacement using the cosine function (that relates adjacent side with hypotenuse):

east\,\, comp=3.1 * cos(25^o)\approx 2.809\,\,km

and we can calculate the north component using the sine function that relates the opposite side to the angle with the hypotenuse.

north\,\,component = 3.1 * sin(25^o) \approx 1.31 \,\,km
