Answer:
4.41 W
Explanation:
P = IV, V = IR
P = V² / R
Given that P = 0.0625 when V = 1.50:
0.0625 = (1.50)² / R
R = 36
So the resistor is 36Ω.
When the voltage is 12.6, the power consumption is:
P = (12.6)² / 36
P = 4.41
So the power consumption is 4.41 W.
<span>(a) 39.5 g
(b) 49.53 cm^3
(c) 0.7975 g/cm^3, liquid is an alcohol
(a) This will be the difference between the weight of the iron in air and the weight submerged in fluid. So:
390.0 g - 350.5 g = 39.5 g
(b) The density of iron is 7.874 g/cm^3, so the volume of the iron chunk is
390.0 g / 7.874 g/cm^3 = 49.53 cm^3
(c) The density of the fluid will be the mass of the fluid divided by the volume, so:
39.5 g / 49.53 cm^3 = 0.7975 g/cm^3
Since the density is very dependent upon the temperature and since the temperature wasn't specified, the actual substance can't be completely identified. Although some candidates are:
1. Mixture of Alcohol and water. Density ranges from 0.785 g/cm^3 to 1.000 g/cm^3.
2. Crude oil. Density 0.790 g/cm^3
3. Hydrazine. Density 0.795 g/cm^3
4. Methanol. Density 0.791 g/cm^3
5. Ocimene. Density 0.798 g/cm^3
The most likely candidate is a high concentration of an alcohol of some sort.</span>
Answer:
Time period, T = 403.78 years
Explanation:
It is given that,
Orbital distance,
Mass of the Earth,
Mass of the planet,
Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.
or
T = 403.78 years
So, the orbital period of this planet is 404 years. Hence, this is the required solution.
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.
