<span>Beyond the philosophical objections there was also initially a very serious question about what force would be sufficiently large to continue pushing large plates of rock. The original proposer of the modern theory, Wegener, has not compelling answer to this question. We now know there are convection currents in the earth mantle under the continental plates that provide such a force.</span>

taurus [48]

The force required to start an object sliding across a uniform horizontal surface is larger than the force required to keep the object sliding at a constant velocity once it starts.

The magnitudes of the required forces are different in these situations because the force of kinetic friction is less than the force of static friction. <em>(d)</em>

Razona si, en las experiencias de Faraday, el efecto producido moviendo el circuito será el mismo que el producido moviendo el i
const2013 [10]

Answer:

moving the circuit or the magnet gives the same result

Explanation:

The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential

          fem = \frac{d \phi }{dt}dfi / dt

the magnetic flux is

         Ф = B. A = B A cos θ

suppose for simplicity that the angle is zero so cos 0 = 1

         Φ = B A

By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.

Consequently moving the circuit or the magnet gives the same result

a heat engine with an efficiency of 30.0% performs 2500 j of work. how much heat is discharged to the lower temperature reservoi
Free_Kalibri [48]

Answer:

Q₂ = 5833.33 J

Explanation:

First we need to find the energy supplied to the heat engine. The formula for the efficiency of the heat engine is given as:

η = W/Q₁

where,

η = efficiency of engine = 30% = 0.3

W = Work done by engine = 2500 J

Q₁ = Heat supplied to the engine = ?

Therefore,

0.3 = 2500 J/Q₁

Q₁ = 2500 J/0.3

Q₁ = 8333.33 J

Now, we find the heat discharged to lower temperature reservoir by using the formula of work:

W = Q₁ - Q₂

Q₂ = Q₁ - W

where,

Q₂ = Heat discharged to the lower temperature reservoir = ?

Therefore,

Q₂ = 8333.33 J - 2500 J

<u>Q₂ = 5833.33 J</u>
