Using the power of the tides, energy is produced from the gravitational pull from both the moon and the sun, which pulls water upwards, while the Earth's rotational and gravitational power pulls water down, thus creating high and low tides.

Examples of student-led organizations are:
- Academic and educational organizations
- Community service organization
- Media and publications organizations
- Political or multicultural organizations
- Recreation and sports organizations
- Student government organizations
- Religious and Spiritual organizations
The benefits of getting involved in any of these are many. They include but are not limited to:
- It helps one to learn more about oneself
- It is a great place to develop leadership skills
- It offers the opportunity for people to build life-long networks
- Skills learned in class can be practiced and honed in these organizations
- Soft skills such as team-intellignce, and social intelligence can be learned in these organizations
- Valuable experiences that count in real-life jobs can be learned here
- It is also an opportunity to give back to the community and to have fun

Answer:
8.333*10^-6 ohms
Explanation:
Resistivity of a material is expressed as;
p = RA/l
R is the resistance of the material
A is the cross sectional area
l is the length of the material
Given
R = 5 ohms
A = 0.5mm^2
A = 5 * 10^-7m^2
l = 30cm = 0.3m
Substitute into the formula;
p = (5 * 5 * 10^-7m^2)/0.3
p = 25 * 10^-7/0.3
p = 0.0000025/0.3
p = 8.333*10^-6
Hence its resistivity at 20 degrees Celsius is 8.333*10^-6 ohms
<span> An electroscope that might have a static charge is tested on a metal surface. From there, the charges move to the metal and straight to the foil leaves. If they repel, or move away from each other, that means they have identical charges. This applies for both positive and negative static electricity.

Answer:
Explanation:
Given:
- temperature of skin,
- initial temperature of steam vapour,
- latent heat of steam,
- mass of steam,
- specific heat of water,
- final temperature,
<em>Assuming that no heat is lost in the surrounding.</em>
<u>We know:</u>
<u>Now the total heat given by the steam to form water at the given conditions:</u>
..............................(1)
where:
latent heat given out by vapour to form water of 100°C
heat given by water of 100°C to come at 34°C.
putting respective values in eq. (1)
is the heat transferred to the skin.
