The moving energy is 5,000 m/s
Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.
Answer:
The distance that the spring compresses is:
Explanation:
<u>Kinetic and Elastic Potential Energy</u>
The kinetic energy of an object of mass m traveling at a speed v is:
The elastic potential energy of a spring of constant k that compresses a distance x is:
The block of mass m is moving at a speed v when compresses a spring of constant k. The kinetic energy will eventually transform into elastic energy, but before that, both energies will be equal. It happens when:
Simplifying:
Dividing by k:
Taking square root:
The distance that the spring compresses is
Answer:
Explanation:
mass of coffee filter, m = 1.4 h
height, h = 4 m
velocity, v = 0.5 m/s
The energy conservation
Potential energy of filter = kinetic energy of filter + energy gained by the air molecules
m x g x h = 0.5 x mv² + energy gained by the air molecules
0.0014 x 9.8 x 4 = 0.5 x 0.0014 x 0.5 x 0.5 + Energy gained by the air molecules
Energy gained by the air molecules = 0.05488 - 0.00000175
= 0.054878 J
The law of conservation of mass states that mass can neither be created or destroyed, hence we expect product mass to equal reactant mass.
mass of propane + mass of oxygen = mass of carbon-dioxide + water
Using stochiometry, we first write a balanced the equation
The ratio of propane to oxygen is 1:5, 1 mol propane reacts with 5 mol oxygen
First find the moles of propane using the mass of propane 44g and molecular mass of propane 44.1g/mol
The grams of oxygen would be, using molecular mass 32 g/mol
The answer rounded to 3 significant figures gives us .
