If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion.

A long wire carrying I=1.1A of constant current oriented North-to-South (and the current is running northwards) is placed horizo

Tema [17]

Answer:

The absolute value of the angular deviation is 39.3°.

Explanation:

Given that,

Current = 1.1 A

Distance = 0.9 cm

Magnetic field = 20μT

We need to calculate the magnetic field due to wire

Using formula of magnetic field

$B=\dfrac{\mu_{0}I}{2\pi d}$

Put the value into the formula

$B=\dfrac{4\pi\times10^{-7}\times1.1}{2\pi\times0.9\times10^{-2}}$

$B=24.4\times10^{-6}\ T$

$B=24.4\ \mu T$

We need to calculate the absolute value of the angular deviation

Using formula of direction

$\theta=\tan^{-1}(\dfrac{B_{E}}{B_{w}})$

$\theta=\tan^{-1}(\dfrac{20 \mu}{24.4 \mu})$

$\theta=39.3^{\circ}$

Hence, The absolute value of the angular deviation is 39.3°.

One mole of titanium contains how many atoms?

Vladimir [108]

Answer:

$\boxed {\boxed {\sf D. \ 6.02*10^{23} \ atoms}}$

Explanation:

One mole of a substance contains the same amount of representative particles. These particles can be atoms, molecules, ions, or formula units. In this case, the particles are atoms of titanium.

Regardless of the particles, there will always be <u>6.02*10²³</u> (also known as Avogadro's Number) particles in one mole of a substance.

Therefore, the best answer for 1 mole of titanium is D. 6.02*10²³ atoms.

Two children are pulling on opposite sides of a blanket. The brother is pulling with a force of 3 N. The sister is pulling with

Citrus2011 [14]

Let F1=Force exerted by the brother (+F1)
F1= Force exerted by the sister (-F2)

Fnet=(+F1) + (-F2)
Fnet= (+F1) + (-F2)
Fnet=F1 - F2
Fnet= (+3N)+(-5N)
Fnet= -2N

-F

towards the sister (-F) (greater force applied)
