Answer:
60 Ω
Explanation:
R(com) = 15 Ω
1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn
1/15 = 1/20 + 1/R2
1/R2 = 1/15 - 1/20
1/R2 = (4 - 3) / 60
1/R2 = 1/60
R2 = 60 Ω
así, la combinada de resistencia necesaria es 60 Ω

Answer:
In an year about 6 major hurricanes and 3 minor storms occurs.
Explanation:
- Hurricanes are increasing in number and frequency to the increasing impact of global warming. As current research states that climate change in the tropics results in an increased storm frequency.
- The presence of extra heat in the air or the oceans form the stoma that leads to the production of such energy. According to o the 200-2007 data shows in the huge increase in the storm frequency and this suggests the impact of climate warming.
To develop this problem it is necessary to apply the concepts related to Work and energy conservation.
By definition we know that the work done by a particle is subject to the force and distance traveled. That is to say,
Where,
F= Force
d = Distance
On the other hand we know that the potential energy of a body is given based on height and weight, that is
The total work done would be given by the conservation and sum of these energies, that is to say
PART A) Applying the work formula,
PART B) Applying the height equation and considering that there is an angle in the distance of 25 degrees and the component we are interested in is the vertical, then
The net work would then be given by
Therefore the net work done by these 2 forces on the cannonball while it is in the cannon barrel is 3355J
Answer:
c is correct
Explanation:
Steel is a metal that is made from iron and carbon. During the steel making process, iron & carbon are melted together, and is allowed to harden into a solid. The iron and the carbon DO NOT chemically react with each other. After the steel was made, 20 samples were taken from one piece and tested. Each sample contained 98% iron and 2% carbon.
Which of the following terms BEST describes steel? homogeneous mixture
