On which variable does magnetic flux depend?A) the magnetic fieldB)the orientation of the field with respect to the region throu

hram777 [196]

Answer:

D) All of these

Explanation:

The magnetic flux through a coil of wire is given by:

$\Phi = BA cos \theta$

where

B is the intensity of the magnetic field

A is the area enclosed by the coil

$\theta$ is the angle between the direction of B and the normal to the area of the coil

Therefore, we see that the magnetic flux depends on all these quantities:

A) the magnetic field

B)the orientation of the field with respect to the region through which it passes

C)the area of a region through which magnetic field passes

So, the correct answer is

D) All of these

Assume that the cart is free to roll without friction and that the coefficient of static friction between the block and the cart

Dahasolnce [82]

Answer: $F=\frac{(M+m)g}{\mu _s}$

Explanation:

Given

Trolley of mass M is free to roll without friction

coefficient of friction between trolley and mass m is $\mu _s$

Force F is applied on mass m

Acceleration of the system is

$a=\frac{F}{M+m}$

friction Force will balance weight of block

friction force $=\mu _sN$

$N=ma$

$\mu _sN=mg$

$\mu _sma=mg$

$\mu _s=\frac{g}{a}$

$F=\frac{(M+m)g}{\mu _s}$

An ion's position vector is initially r = 8.0 i - 4.0 j + 3.0 k, and 8.0 s later it is r = 4.0 i + 8.0 j - 6.0 k, all in meters.

tangare [24]

The average velocity = Displacement between two points/ Time taken for that displacement

In this case An ion's position vector is initially r = 8.0 i - 4.0 j + 3.0 k, and 8.0 s later it is r = 4.0 i + 8.0 j - 6.0 k

So, displacement = 4.0 i + 8.0 j - 6.0 k - (8.0 i - 4.0 j + 3.0 k)

= -4.0 i + 12.0 j - 9.0 k

So velocity, V = (-4.0 i + 12.0 j - 9.0 k)/8

= -0.5 i + 1.5 j - 1.125 k

So average velocity during 8 seconds = -0.5 i + 1.5 j - 1.125 k

A dog runs with an initial speed of 1.5 m/s on a floor. It slides to a stop with an acceleration of -0.35 m/s^2. How long does i

Neko [114]

Answer:

3.214 m

Explanation:

Here object is moving in a constant acceleration. Then we can use motion equations to find the total distance

V² = U² + 2as

0 = 1.5² + 2×-0.35 × s

s = 3.214 m

symbols has usual meanings.
