Astronomers use different types of telescopes to observe different parts of the electromagnetic spectrum. This allows astronomers to study objects in space.
Each type of electromagnetic wave can travel through space at the speed of
light. Sometimes astronomers will use two telescopes on opposites sides of a
planet and combine the image from each telescope. When combined, the two
telescopes act like one giant telescope and have the ability
to reveal important
details from space.

A: Gamma Rays
B: Ultraviolet
C: Microwabe
D: Radio wabes

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
