Which hemisphere is experiencing summer in july?

Use the diagram to explain how convection occurs inside the earth. What could convection cause to occur on earths surface

liubo4ka [24]

Answer:

mantle convection is the very slow creeping motion of earths solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.

Points A, B, and C lie along a line from left to right, respectively. Point B is at a lower electric potential than point A. Poi

djyliett [7]

Answer:

A) The particle will accelerate in the direction of point C.

Explanation:

As we know that

potential at points A, B,C and D as V_A, V_B, V_C, V_D and it is clear from the question that

V_A>V_B>V_C

And we know that flow is always from higher to lower potential (for positive charge due to positive potential energy).

So the charge will accelerate from B toward C.

Hence, the correct option is A.

An electromagnetic flowmeter is useful when it is desirable not to interrupt the system in which the fluid is flowing (e.g. for

AURORKA [14]

Answer:

2 m/s

Explanation:

The electromagnetic flow-metre work on the principle of electromagnetic induction. The induced voltage is given as

$E = Blv$

where $E$ is the induced voltage = 2.88 mV = 2.88 x 10^-3 V

$l$ is the distance between the electrodes in this field which is equivalent to the diameter of the tube = 1.2 cm = 1.2 x 10^-2 m

$v$ is the velocity of the fluid through the field = ?

$B$ is the magnetic field = 0.120 T

substituting, we have

2.88 x 10^-3 = 0.120 x 1.2 x 10^-2 x $v$

2.88 x 10^-3 = 1.44 x 10^-3 x $v$

$v$ = 2.88/1.44 = 2 m/s

A clay cylinder of radius 17 cm on a potter's wheel spins at a constant rate of 12 rev/s. The potter applies a normal force of 1

Scorpion4ik [409]

Answer:

0.37 W

Explanation:

e potter provide torque which then causes power developed in the wheel to rotate.

The power delivered, P is found by

$P=\tau\omega$ where $\omega$ is angular speed on the wheel and \tau is torque on the wheel

Frictional force $F_{k}$ developed between the hands of the potter and the wheel is given by

$F_{k}=\mu F_{N}$ where $\mu$ is coefficient of friction and $F_{N}$ is perpendicular force on the wheel caused by the potter’s hands

Torque on the wheel is given by

$\tau=RF_{K}$ where R is radius of the wheel

$\tau=R\mu F_{N}
$

To convert the wheel spin rate from rev/s to rads/s

$\omega=\frac {12rev/s}{2\pi rev/rad}$ = 1.909859 rad/s

Substituting the above \omega into the equation of power

P= $\omega\tau=\omega R\mu F_{N}
$

P=1.909859 rad/s *0.17m*0.1*11.3N=0.366884 W

Power delivered by the potter to the wheel is 0.37W
