Magnitude F have a

lakkis [162]

Answer:

120°

Explanation:

Given forces with magnitude F and F

Applying the parallelogram law of vector

Where resultant is given as :

R = √(A^2 + B^2 + 2ABCos Ф

WHERE A and B are two forces with angle Ф

F =√(F^2 + F^2 + 2F * F Cos Ф

Square both sides

F^2 = F^2 + F^2 + 2F^2 CosФ

F^2 - 2F^2 = 2F^2 CosФ

- F^2 = 2F^2 Cos Ф

Divide both sides by 2F^2

- 1 / 2 = CosФ

Cosine(theta) = - 1/2

Ф = cosi^-1 (-1/2)

Ф = 120°

Define the term displacement. Is it a vector quantity or a scalar quantity?

Aleks04 [339]

Explanation:

The difference between final and initial position of an object is called its displacement. Its formula is given by :

$\text{displacement}=\text{final position}-\text{initial position}$

It is equal to the shortest path covered by it. It is a vector quantity. It has both magnitude and direction.

A curent-carrying 2.0-cm long segment of wire is inside a long solenoid adius - 40 cm - 800 turns/m, current - 50 mA). The wire

klasskru [66]

Answer:

The value is $F_{max} = 12 \muN$

Explanation:

From the question we are told that

The length is $l = 2.0 \ cm = 0.02 \ m$

The radius of the the solenoid is $r =40 \ cm$

The number of turns per meter is $N = 800 \ turns / m$

The current through the solenoid is $I = 50 \ mA = 50*10^{-3} \ A$

The current through the segment is $I_s = 12 \ A$

Generally the magnetic force is mathematically represented as

$F = B * I_s l sin(\theta)$

At maximum $\theta = 90^o$

$F_{max} = B * I_s l$

Here B is the magnetic field is mathematically represented as

$B = \mu_o * N * I$

Here $\mu_o$ is the permeability of free space with value

$\mu_o = 4\pi * 10^{-7} N/A^2$

$B = 4\pi * 10^{-7} * 800 *50*10^{-3}$

=> $B = 5.0272 *10^{-5} \ T$

$F_{max} = 5.0272 *10^{-5} * 12 * 0.02$

$F_{max} = 1.2 *10^{-5}$

$F_{max} = 12 \muN$
