Answer:

a neutral atom doesn't have a charge and an ion does.

Explanation:

When atoms bond they can gain or lose electrons which gives them a charge.

anion = negatively charged ion

cation = positively charged ion

What electric force would a stationary 3.8 C charge experience if it were far away from any other charges

MAVERICK [17]

Answer:

The electric force will be 0 N

Explanation:

From the question we are told that

The magnitude of the charge is $q_1 = 3.8 \ C$

Generally from Coulombs law the electric force between two charges is mathematically represented as

$F = \frac{ k * q_1 q_2 }{r^2}$

Here r is the distance of separation between that two charges.

Now from the question we are told that the charge is far away from any other charge hence we can say that the distance between the charge and any other charge is $r = \infty$

$F = \frac{ k * 3.8 * q_2 }{\infty^2}$

=> $F =0 \ N$

Hence the electric force will be 0 N

Answer:

The speed will be "18km/s". A further explanation is given below.

Explanation:

According to the question, the values are:

Wavelength,

$\lambda = 656.46 \ nm$

$\Delta \lambda = 0.04$

$c=3\times 10^8$

As we know,

⇒ $\frac{\Delta \lambda}{\lambda} =\frac{v}{c}$

On substituting the values, we get

⇒ $\frac{656.46}{0.04} =\frac{v}{3\times 10^8}$

⇒ $v=\frac{656.46}{0.04} (3\times 10^8)$

⇒ $=16411.5\times 3\times 10^8$

⇒ $=18280 \ m/s$

or,

⇒ $=18 \ km/s$

A spindle connects two wheels with fixed axles by a fan belt. If the effort wheel is larger than the resistance wheel, which axl

MariettaO [177]

Power = Iω (constant) as they are connected together, since effort axle has large radius than resistance axle, so moment of inertia of effort axle is also more as compared to resistance axle, so angular speed of effort axle is less than the resistance axle. So answer is B. resistance axle will have more angular speed as its moment of inertia is less for the same power.
