Asub-marine is 300 m horizontally out from the shore and 90 m beneath the surface of the water. a laser beam is sent from the sub so that it strikes the surface of the water at a point 210 m from the shore. if the beam just strikes the top of a building standing directly at the water's edge, find the height of the building.

the height of the building h= 133.37 m

Explanation:

from the figure,

The angle of incidence of water surface is

=45°

angle of reflection is

=70.12°

The height of the building h

h= 133.37 m

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

a person with a mass of 106kg has a weight of 1060n
