Answer:

Magnetic dipole moment will be15.51\times 10^{-3}J/T

Explanation:

We have given length of the cylinder , that is h = 5.51 cm = 0.051 m

And diameter of the cylinder d = 0.865 cm

So radius r=\frac{d}{2}=\frac{0.865}{2}=0.4325cm=0.4325\times 10^{-2}m

So volume of cylinder V=\pi r^2h=3.14\times (0.4325\times 10^{-2})^2\times 0.051=3\times 10^{-6}m^3

It is given there is uniform magnetization of M=5.17\times 10^3A/m

We have to fond the dipole moment

Dipole moment is equal to \mu =MV, here M is magnetization and V is volume

So \mu =MV=5.17\times 10^3\times 3\times 10^{-6}=15.51\times 10^{-3}J/T

The leaves of a tree lose water to the atmosphere via the process of transpiration. A particular tree loses water at the rate of
Gnoma [55]

Answer:

The speed of the sap flowing in the vessel is 1.90 mm/s

Explanation:

Given:

The rate of water loss, Q = 3 × 10 ⁻⁸ m³/s

Number of vessels contained, n = 2000

Diameter of the vessel, D = 100 Mu m

thus, the radius of the vessel, r = 50 × 10⁻⁶ m

Now, the rate of flow is given as:

Q = AV    .............(1)

where, A is the area of the cross-section

V is the velocity

Total area, A = n × (πr²)

substituting the values in the equation (1), we get

3 × 10 ⁻⁸ m³/s = [2000 × (π × (50 × 10⁻⁶)²)] × V

or

V = 1.909 × 10⁻³ m/s or 1.90 mm/s

Hence, the speed of the sap flowing in the vessel is 1.90 mm/s

a microwave uses a 14 a of electricity if 120 v is run through it what is the resistance of the microwave
Airida [17]
Resistance = voltage / current.

That's. 120v / 14A = 8.57 ohms.

By the way, voltage doesn't "run through" anything. Current does. That would be the 14 Amps.

A conveyor belt is used to move sand from one place to another in a factory. The conveyor is tilted at an angle of 18° above the
brilliants [131]

Answer:

x = 2.044 m

Explanation:

given data

initial vertical component of velocity = Vy = 2sin18

initial horizontal component of velocity = Vx = 2cos18

distance from the ground yo = 5m

ground distance y = 0

from equation of motion

y = yo+ V_y t +\frac{1}{2}gt^2

0 = 5 + 2sin18+ \frac{1}{2}*9.8t^2

solving for t

t = 1.075 sec

for horizontal motion

x = V_x t

x = 2cos18*1.075

x = 2.044 m
