An integrated circuit is a ___.

1 answer:

5 0

HI buddy!

An integrated circuit(IC) is a semiconductor water on which thousands of tiny resistors, transistors are fabricated.

Remember that an integrated circuit are the heart and brains of most circuits. They are the keystone of modern electronics.

I hope this helps!

Scorpion4ik [409]

Answer:

Explanation:

Part A

Every force has one and only pair force , according to 3 rd law

It is true , the pair force has equal magnitude .

Part B

The two forces in each pair act in opposite directions.

It is true .

The pair forces are equal and act in opposite direction .

Part C

The two forces in each pair can either both act on the same body or they can act on different bodies.

It is false .

The two forces in each pair can not act on same body . They act on different bodies , bodies which are undergoing mutual interaction.

An eraser is thrown upward with an initial velocity of 5.0m/s. The eraser’s velocity after 7.0 second is

sladkih [1.3K]

Answer:

-63.6m/s

Explanation:

Given parameters:

Initial velocity = 5m/s

Time of flight = 7s

Unknown:

Velocity of the eraser after 7s = ?

Solution:

To solve this problem, we have to use the right motion equation which is given below;

v = u - gt

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity = 9.8m/s²

t is the time taken;

Now insert the parameters and solve for v;

v = 5 - (9.8 x 7)

v = -63.6m/s

A 65 kg box is lifted by a person pulling a rope a distance of 15 meters straight up at a constant speed. How much Power is requ

Y_Kistochka [10]

Answer:

Power is 1061.67W

Explanation:

Power=force×distance/time

Power=65×9.8×15/9 assuming gravity=9.8m/s²

Power=3185/3=1061.67W

Which circle has minimum flux in the following figure?

Feliz [49]

Answer:

Circle Q

Explanation:

The flux of a field through a surface is given by:

$\Phi = F A cos \theta$

where

F is the field strength

A is the area of the surface

$\theta$ is the angle between the direction of the field and the normal to the surface

In the figure, we see that the 4 surfaces have different orientations, so different angle $\theta$ . In the formula, we see that the flux is maximum when $\theta=0^{\circ}$ , which occurs when the field is perpendicular to the surface, and the flux is zero when $\theta=90^{\circ}$ , (because $cos 90^{\circ}=0$ ) which occurs when the field is parallel to the surface.

In the figure, we see that circle Q is parallel to the direction of the field, so in this case the field is zero, while in all the other cases is not.

So, the correct answer is

Circle Q
