Answer:

38.68 °C

Explanation:

Using,

F = BILsinФ....................... Equation 1

F/L = BIsinФ...................... Equation 2

Where F/L = force per unit length, B = Magnetic Field, I = current, Ф = angle between the wire and the magnetic Field

make Ф the subject of the equation

Ф = sin⁻¹[(F/L)/BI]................... Equation 3

Given: F/L = 2 N/m, B = 80 mT = 0.08 T, I = 40 A.

Substitute into equation 3

Ф = sin⁻¹(2/(0.08×40))

Ф = sin⁻¹(0.625)

Ф = 38.68 °C

Hence the angle between the wire and the magnetic Field = 38.68 °C

Answer:

38.7°

Explanation:

The force on a current carrying wire is given as

F = (B)(I)(L) sin θ

where

B = magnetic field = 80 mT = 0.08 T

I = current in the wire = 40 A

(F/L) = 2.0 N/m

θ = angle between the magnetic field and the direction of current flow (basically angle between the wire and the magnetic field) = ?

(F/L) = (B) (I) sin θ

2 = 0.08 × 40 × sin θ

sin θ = (2/3.2) = 0.625

θ = sin⁻¹ (0.625)

θ = 38.7°

Hope this Helps!!!

How will unbalanced forces affect the speed and direction of an object
azamat

Answer:

Explanation:

Unbalanced forces will result in the presence of acceleration. The formula

F net = ma

says that if there is a net force present and the object in question has a mass, then an acceleration is present. Now acceleration is constant in this situation because nowhere does it say the acceleration is changing. If acceleration is constant then the velocity is increasing at a steady pace (think linear function!).

The direction of the object depends on the direction that the net force is in. If the net force is to the left, then that object will accelerate to the left.

Hope this helps :)

A spider begins to spin a web by first hanging from a ceiling by his fine, silk fiber. He has a mass of 0.025 kg and a charge of
Rasek [7]

Answer:

a) (5.59 × 10³) N/C

b) 0.226 N directed away from the spider.

Explanation:

a) Electric field, E, felt as a result of point charge, Q, at a distance, d away is given by

E = kQ/d²

So, magnitude of the electric field due to the charge on the second spider at the position of the first spider

Q = 4.2 µC = 4.2 × 10⁻⁶ C

k = Coulomb's constant = 8.99 × 10⁹ Nm²/C

d = 2.6 m

E = (8.99 × 10⁹ × 4.2 × 10⁻⁶)/2.6²

E = 5.59 × 10³ N/C

b) Tension in the silk fiber above the spider is the net force due to the weight of spider one and the force of repulsion due the two charges.

Force due to the two charges = Eq

where q now represents the charge of the first spider at the first point, feeling the electric field calculated in (a)

F = 5.59 × 10³ × 3.4 × 10⁻⁶ = 0.01901 N directed upwards. (That is, F = + 0.019 N)

Weight of the spider = mg = 0.025 × 9.8 = 0.245 N directed downwards. (That is, W = -0.245 N)

Net force, T = mg - F = 0.245 - 0.019 = 0.226 N (that is, 0.226 N, directed upwards, away from the spider).
