Answer: 0.091 m

Explanation:

r = 1/B * √(2mV/e), where

r = radius of their circular path

B = magnitude of magnetic field = 1.29 T

m = mass of Uranium -238 ion = 238 * amu = 238 * 1.6*10^-27 kg

V = potential difference = 2.9 kV

e = charge of the Uranium -238 ion = 1.6*10^-19 C

r = 1/1.29 * √[(2 * 238 * 1.6*10^-27 * 2900) / 1.6*10^-19]

r = 1/1.29 * √(2.21*10^-21 / 1.6*10^-19)

r = 1/1.29 * √0.0138

r = 1/1.29 * 0.117

r = 0.091 m

Therefore, the radius of their circular path is 0.091 m

A city of Punjab has a 15 percent chance of wet weather on any given day. What is the probability that it will take a week for i
lilavasa [31]

Answer:

so the probability will be = 0.062

Standard deviation =  0.8925

Explanation:

The probability of rain = 15% = 15/100= 0.15

and the probability of no rain=q = 1-p= 1-0.15= 0.85

The number of trials = 7

so the probability will be

7C3 * ( 0.15)^3 (0.85)^4= 35* 0.003375 * 0.52200 =0.06166= 0.062

Taking this as binomial as the p and q are constant and also the trials are independent .

For a binomial distribution

Standard deviation = npq= 0.15 *0.85 *7= 0.8925

Question: As the moon spins on its axis we see
butalik [34]

Answer:

<h2><em><u>A) Different parts of the moon throughout the month</u></em></h2>

Explanation:

Every thing I researched on the moon never says you can see all sides of the moon while its spinning expect the full moon. Your gonna see different sides of the moon because it is spinning not staying still. The last one is wrong because the moon goes threw a cycle. (sorry if anything is wrong this is just what I've been learning and understanding about the moon)

3. A force of 90N pushes downward at an angle of 32° to the horizontal on an object resting on the floor. The
Nonamiya [84]

F = m × g

Now when, a force acts on the object at an angle and in downwards, thus formula becomes:

= N = mg + F sin(x)

Here,

  • N = normal force, m = mass , g = acceleration due to gravity, F = outside force, x = the angle formed

See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:

= N = w + F sin(x) --------- [Weight = w]

Now, the solutions becomes easy from here, just put the values:

= N = w + F sin(x)

= 200 = w + 90 × sin(32)

= 200 = w + 90 × 0.55

= 200 = w + 49.5

= 200 - 49.5 = w

= 150.5 = w

I have got my answer but in approx, hope you will not mind. ^^"

The coil of wire in the center of the screen encompasses an area through which magnetic field lines pass, so there is a magnetic
fredd [130]

Answer:

<em>No, the coil will produce no flow of current or potential difference.</em>

Explanation:

Magnetic field flux is the number of magnetic field line passing through a given area. It depends on the area and the magnetic field strength through this area. For electromagnetic induction to occur, there must be a constantly changing magnetic field. This is according to Faraday's law of electromagnetic induction that states that the induced EMF is directly proportional to the rate of change in flux ΔФ/Δt, and is also proportional to the number of turns on the coil. A changing magnetic field will lead to a break in the flux linkage, which induces current or potential difference on the coil. A stationary coil through a magnetic filed will therefore produce no electric flow of current or potential difference on the coil.
