Because cl atoms are bonded with hydrogen. hydrogen bond is very strong bond
Rocks are made of many different materials. Different types of rocks are made from different sediments. Depending on the sediment that the rock is made of depends on how strong the rock will be. There are six main types of sedimentary rocks. All of the rocks are different colors depending on the sediments it consist of.
Answer:
There will not be any ejection of photoelectrons
Explanation:
Energy of the photon= hc/λ
Where;
h= Plank's constant
c= speed of light
λ= wavelength of the incident photon
E= 6.6×10^-34 × 3 ×10^8/488 × 10^-9
E= 4.1 ×10^-19 J
Work function of the metal (Wo)= 2.9 eV × 1.6 × 10^-19 = 4.64 × 10^-19 J
There can only be ejected photoelectrons when E>Wo but in this case, E<Wo hence there will not be any ejection of photoelectrons.

Answer:
As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off.
