Hydrogen and oxygen bond because when more molecules are present, as is the case with liquid water, more bonds are possible because the oxygen of one water molecule has two lone pairs of electrons, each of which can form a hydrogen bond with a hydrogen on another water molecule.
Answer:
green light have high energy
Explanation:
We have given the wavelength of the red light
Speed of the light
The energy of the signal is given by
The frequency of the green light is given by:
So energy
So green light have high energy
Air bags are kept in the steering wheel or
dashboard and expand during a serious collision, usually a front collision that
occurs at over 10 mph. To do its important job, an air bag comes out of the
dashboard at up to 200 mph, faster than the blink of an eye. It is estimated
around 10 inches of space to inflate. The force of an air bag can hurt those
who are too close to it. Driver and front seat passengers should be
moved as far back as practical, mainly people of short built. It is highly suggested
that you be seated no less than 10 inches away from the air bag. Therefore, the answer is letter b.
Answer:
If an object accelerates from rest, with a constant acceleration of 5.4 m/s2, what will its velocity be after 28s? v0 = 0 v= ? a = 5.4 m/s2. ∆x = t = 28 s. 3.
