Answer:

The magnetic flux through surface is 2.22 \times 10^{-3} Wb

Explanation:

Given :

Magnitude of magnetic field B = 0.078 T

Radius of circle r = 0.10 m

Angle between field and surface normal \theta = 25°

From the formula of flux,

\phi = B.A

\phi = BA\cos \theta

Where \theta = angle between magnetic field line and surface normal, A = area of circular surface.

A = \pi r^{2}

A = 3.14 \times (0.10) ^{2}

A = 0.0314 m^{2}

Magnetic flux is given by,

\phi = 0.078 \times 0.0314 \times \cos 25

\phi = 2.22 \times 10^{-3} Wb

Therefore, the magnetic flux through surface is 2.22 \times 10^{-3} Wb

The cpu might be covered by a(n) ________, which dissipates the heat generated by the chip.
FinnZ [79.3K]
I think he correct term to fill in the blank would be heat sink. The CPU might be covered by a heat sink, which dissipates the heat generated by the chip. A heat sink is any device or a substance that absorbs heat generated or from the heat reservoir. For a device, it would be one that has a fan or a peltier device in order to keep a system having a cool temperature. This is done to protect a system from any damage due to excess heat. This protect any device from overheating. A CPU surely have this device because it should be kept cool to protect the chips inside it.

PLEASE HELP ):
jolli1 [7]

The first thing we must do for this case is the sum of forces in a horizontal direction.

We have then:

F1 + F2 = m * a

Substituting values we have:

50 + 75 = m * 2.5

From here, we clear the mass of the object:

m * 2.5 = 125\\m = 125 / 2.5\\m = 50 Kg

We now look for the weight of the object.

W = m * g

Where,

g: acceleration of gravity (9.8 m/s^2)

Substituting values:

W = 50 * 9.8\\W = 490 N

Answer:

the weight of the object is:

W = 490 N
