Waves are caused by blank and tides are caused by blank
Sergio [31]

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves.

Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). ... Tidal forces are based on the gravitational attractive force.

If the Tides is working then out “ High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides“.

Which statement applies to electronegativity?
joja [24]

Answer: Option (A) is the correct answer.

Explanation:

Electronegativity is the ability of an atom to attract electrons towards itself.

When we move across a period in the periodic table then there occurs an increase in the electronegativity of the elements because of decrease in their atomic size.

This is because electrons add to the same sub-shell and due to electrostatic force of attraction from the nucleus they get pulled closer towards the nucleus leading to shrinkage in size.

And, smaller is the size of an atom more readily it will attract an electron.

Therefore, we can conclude that electronegativity increases across a period.

How many grams of hydrogen are needed to produce 1.80 g of water according to this equation? 2H2 + O2 → 2H2O
s344n2d4d5 [400]
Answer is c

Work out the moles of 2H2O: 1.80/ (16+1+1) = 0.1
The moles of 2H2 are the same (0.1)
The Mr of H2 is 2

So the mass needed to produce 1.80g of water is
0.1 x 2 = 0.2
