Answer:
She will make the mass of the smiley face twice as massive in order to keep the mobile in perfect balance.
Explanation:
mass of an object is directly proportional to the cube of its length. In this case the length is constant, the mass will also be constant for the smiley face, so that the mobile will be kept in perfect balance.
Therefore, If Anya decides to make the star twice as massive, and not change the length of any crossbar or the location of any object, she will make the mass of the smiley face twice as massive in order to keep the mobile in perfect balance.
Answer:
Explanation:
Let the internal resistance be r .
Since in open circuit the volt is 1.55 V , this will be the source voltage .
Source voltage = 1.55
If external resistance be R .
1.55 / (R + r ) = .500
R + r = 3.1 ohm
So sum of internal resistance and external resistance will be 3.1 ohm.
A discovery not the others
<h3><u>Answer;</u></h3>
c) created when tectonic plates converge
<h3><u>Explanation;</u></h3>
- According to the plate tectonics theory, earthquakes, volcanoes and mountain building process occur due to the interaction of the rigid plates on the earth's crust.
- <u>Mountains are as a result of volcanoes which are created by the movement of plate tectonics, which erupt and form mountains.</u> Formation of these mountains is as a result of compression of sediments caused by the collision of two convergent plate boundaries.
- It's along the convergent plate boundaries that interactions occur which creates volcanic activities and mountain building.
The freshwater reservoirs on earth are ranked by volume, with the one with the biggest volume at the top is-
1. ice caps; 2. groundwater; 3. lakes; 4. rivers.
<h3>Explain the freshwater reservoirs on earth?</h3>
The atmosphere, the earth's surface, and the earth's interior are the three main locations where water can be kept.
- Oceans, glacier ice, underground, lakes, soil humidity, living organisms, atmospheric atmosphere, and rivers are examples of these reservoirs, which are used to store water.
- There is an estimated 1.386 billion km3 (330 million cubic miles) of water on Earth, of which 97.5% is salt water and 2.5% is fresh water.
- Only 0.3% of a fresh water is liquid at the surface.
- More than 70% of freshwater is utilized for agriculture in the majority of the world's areas.
- An estimated 50% increase in agricultural output and a 15% increase in water flows are needed by 2050 to feed a globe of 9 billion people.
Thus, the freshwater reservoirs on earth are ranked by volume, with the one with the biggest volume at the top is-
- 1. ice caps
- 2. groundwater
- 3. lakes
- 4. rivers
