Answer:

Speed of light decreases when it goes from a rarer medium to denser medium and increases when it travels from denser to rarer.

Explanation:

when light will fall on aquarium the glass wall and water inside it are denser compared to the air outside. so, the ray will refract from its original path (bending towards the normal) and decrease its speed. The reverse happens when it travels out of aquarium. the air is less dense compared to the water and glass so it will increase the speed.

Which atoms have the highest electronegativity?
Ronch [10]

Answer:

Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).

Type the correct answer in the box. Round your answer to the nearest whole number. Calculate the man’s mass. (Use PE = m × g × h
Blababa [14]

Answer:

56 kg

Explanation:

The change in potential energy of the man is given by:

\Delta U = mg \Delta h

where

m is the man's mass

g is the gravitational acceleration

\Delta h is the change in height of the man

In this problem, we have:

\Delta U=4620 J is the gain in potential energy

g = 9.8 m/s^2 is the gravitational acceleration

\Delta h=8.4 m is the change in height

Re-arranging the equation and substituting the numbers, we find the mass:

m=\frac{\Delta U}{g\Delta h}=\frac{4620 J}{(9.8 m/s^2)(8.4 m)}=56 kg
