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
Explanation:
Total number of buses =9178181
Answer:
Due to application of heat on a saturated solution, the interparticle space increases due to increase in the kinetic energy of the particles which allows more solutes to dissolve in the solution thereby making it unsaturated.
The momentum of a fast object compared to that of a slow object even if they both have the same mass, is their velocities.
Having same mass but different velocities results in different momentum.
Example: mass = 10kg
Velocity 1 = 50 Velocity 2 = 100
Momentum 1 = 10×50 = 500 Ns
Momentum 2 = 10×100 = 1000 Ns
