<h2>
Answer: Nonmetals to Nonmetals </h2>
Covalent bonds hold non-metallic atoms together. These atoms have many electrons in their outermost level and have a tendency to gain electrons rather than to yield them.
In this case the bond is formed by sharing a pair of electrons between the two atoms, one from each atom. Then, this pair of shared electrons is common to the two atoms and holds them together, so that both atoms acquire more stability.
Therefore the correct answer is C.
Answer:
6.17 m
Explanation:
We are given that
Initial speed of rubber ball, u=12 m/s
Total height, h=7 m
Initial speed of second ball, u'=0
We have to find the height at which the two balls collide.
Let first rubber ball and second ball strikes after t time.
For first ball
Distance traveled by first ball in time t
Substitute the value
...(1)
Distance traveled by second ball in time t
.....(2)
Using equation (2) in equation (1) we get
sec
Now, using the value of t
S=6.17 m
Hence, at height 6.17 m the two balls collide .
Answer:
The most common source of energy for surface waves is wind. earthquakes. tides. volcanoes.
Explanation:
Solar energy is the correct answer. Two of the processes that make up the water cycle need solar energy and these include:
1. Transpiration- as plants absorb water from the soil, the soil, the water moves through the stem to the leaves . Once the water reaches the leaves , some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation from the leaves is known as transpiration and requires warmth of the sun (heat energy) to make temperatures jut right for it to take place
2. Evaporation- water that has returned to earth through precipitation and found in rivers, lakes, sea, and ponds when heated by the sun's thermal (solar) heat energy evaporates and as water vapor rises again into the atmosphere.
B Longitude
Explanation:
The line of longitude or longitude does not affects climates.
Climate is the weather condition over a place for a long period of time. It usually takes several years to delineate the climate of an area.
- Longitude is the distance on the earth surface that runs form east to west.
- All lines of longitude are all great circles.
- Latitude are lines from north to south on the earth surface. Only the equator is a great circle.
- Latitude affects climate. In fact based on the division of lines of latitude on can predict climatic patterns on earth.
- Proximity to water bodies also affects climatic condition because of the effect of land and sea breeze and other climatic factors.
- Elevation affects climate a whole lot. Physiography of a place determines the weather to a very large extent.
