Low-grade uranium ore contains a fraction of a percent (by weight) of uranium; very high-grade ore (as is found in some deposits
kolezko [41]

Answer:

2.857 gm

Explanation:

<u>Step 1: Energy from uranium fission </u>

The ratio of energy reeled from uranium to coal= 2.5 million times=2.5*10⁶

<u>step2: mass of uranium 235 required </u>

To get the same energy that of 1 ton coal, the mass reuied will be = (1/2.5) * 10⁻⁶ ton=0.4 * 10⁻³ Kg

where we have taken 1 ton = about 1000Kg

<u>step3: mass of uranium </u>

mass of u-235 = 70% of natural Uranium=0.7 Mu

So Mu= (1/0.7 )* mass of U-235=(0.4 * 10⁻³ Kg)/0.7=0.571 gm

<u>Step 4: Mass of ore </u>

mass of Mu = 20% of ore=0.2 M

So, mass of ore= (1/0.2 )* mass of MU-=(0.571)/0.2 gm=2.857 gm

How does the number of neutrinos passing through your body at night compare with the number passing through your body during the
lapo4ka [179]

Answer:

c)While the amount of neutrinos passing through the Earth does not change much, there is something that changes to you at night. You stop moving and sleep for several hours.  

Think of Neutrinos like rain. During the day you can avoid rain, and run from one dry spot to another(like from a car to a house). At night, however, your asleep, so the rain will hit you for eight hours(if your sleeping outside with no tent for some reason).

A straight wire is aligned east-west in a region where Earth’s magnetic field has magnitude 0.0780 mT and direction 67.1° below
Sergio [31]

Explanation:

It is given that,

Earth's magnetic field, B=0.078\ mT=0.078\times 10^{-3}\ T

Direction of magnetic field, 67.1 degrees below the horizontal, with the horizontal component directed due north.

The magnetic force on the wire per unit length of wire, \dfrac{F}{L}=0.0300\ N/m

(a) The given scenario is shown in the attached figure as :

Using the right hand rule to find the direction of magnetic force on the wire. By using this rule, we get the magnetic force acting on the wire is in upward direction.

(b) Let I is the current flowing in the wire. The magnetic force is given by the following formula as:

F=ILB

I=\dfrac{F}{LB}

I=\dfrac{0.0300}{0.078\times 10^{-3}}

I = 384.61 A

Hence, this is the required solution.
