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
Answer:
o to increase the frequency of sound waves. It increases the sound waves to a level of frequency that humans cannot hear so you won't be able to hear many things though the wall other then low noises like pounding.
Explanation:
I am in construction class as well as a student teacher for other construction type programs trust me :D
Brainiest would be appreciated
Weight of the mass is the tension in the string if the turntable is held fixed, with the mass hanging from the pulley
Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth. Weight (symbolized w ) is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface.
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.
Tension will act opposite the the weight of the mass attached in order to maintain equilibrium .
