A flat coil of wire is placed in a uniform magnetic field that is in the y-direction.

Kitty [74]

Answer:

The correct answer is c

Explanation:

Flow is defined by

Ф = B . A

bold letters indicate vectors.

The magnetic field is directed to the y axis, The area of the coil is represented by a vector normal to the plane of the coil, so to have a flux

i.i = j.j = k.k = 1

and the tori scalar products are zero

a) If the coil must be in the xy plane so that its normal vector is in the Z axis, so there is no flux

b) if the coil is in the plane yz the normal veto is in the x axis, so the flux is zero

C) If the coil is in XZ, the normal vector points in the y direction, usually the scalar product is one and there is a flux in this configuration

The correct answer is c

One liter (1000cm3) of oil is spilled onto a smooth lake. If the oil spreads out uniformly until it makes an oil slick just one

Zepler [3.9K]

Answer:

he diameter of the oil slick is 2523 m

Explanation:

given information?

V = 1 L = 1000 cm³ = 0.001 m³

h = 2 x 10⁻¹⁰ m

first we have to find the radius using the following equation

V = πr²h

r = √V/(πh)

= √(0.001)/(π x 2 x 10⁻¹⁰ )

= 1261.56 m

now, we can calculate the diameter of the oil slick

d = 2r

= 2 (1261.56)

= 2523 m

4720 kj of energy are supplied to a material in order to raise its temperature by 65k. if the specific heat capacity of the mate

jeka57 [31]

The mass of material is 26.6 Kg

Given:

Q = 4720 KJ

Change in Temperature (AT) = 65 K

Specific heat capacity of material (c) = 2730 J K Kg*K

The relation between Q, AT, c and m are related by following formula: Q=m* c*∆T,

Plugging value in heat formula:

4720KJ = m* 2730 J/Kg*K * 65K

4720KJ = m * 177450J/kg

Converting 177450 J/kg to Kg/KJ

177450 J/kg*1KJ/1000J = 177.450KJ/kg

Dividing both side by 177.450KJ/kg

4720KJ/177.450KJ/Kg = m*177.450KJ/Kg÷ 177.450KJ/Kg

Hence, the mass of material = 26.6 Kg

. Mike Powell holds the record for the long jump of 8.95 m, established in 1991. If he left the ground at an angle of 15°, what

nadezda [96]

Answer:

13.3 m/s

Explanation:

The motion is a projectile motion. The horizontal distance travelled, called the range, is given by

$R = \dfrac{u^2\sin2\theta}{g}$

u is the initial speed, $\theta$ is the angle with the horizontal and g is acceleration of gravity.

$u = \sqrt{\dfrac{Rg}{\sin2\theta}}= \sqrt{\dfrac{8.95\times9.81}{\sin30^\circ}}=13.3 \text{ m/s}$
