Answer:
Explanation:
The three things that occur naturally everyday and how science has had an impact on what we think or do about them is
Photosynthesis is a process in which green plants manufacture there own food in the presence of sunlight through the equation below
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
From the equation above, it can be seen that aside from the food (C₆H₁₂O₆) produced by green plants during photosynthesis, science has assisted us in knowing that these green plants take-up the carbon dioxide (CO₂) that is exhaled by humans and release the oxygen (O₂) that is inhaled by humans thereby purifying the air of the surrounding they are found. This concept has made man understand the importance of planting in residential areas.
Depletion of the Ozone layer; the ozone layer is a layer in the earth stratosphere which shields the earth from direct sunlight/rays. Over the years, the burning of hydrocarbon on earth has caused the depletion of this layer thereby exposing the earth to more direct sunlight from the sun. Science has had an impact in the thinking of man in this regard by making us more conscious of the risk of burning these hydrocarbons which has led to the collective efforts by governments across the world to minimize the burning of these substances.
Rain; rain are droplets of water that fall from the atmosphere. Rain formation occurs when water (in the form of ocean, river and/or seas) are evaporated into the atmosphere as a result of heat from the sun. These evaporated water molecule rises and cools down to form and form a cloud It is then returned to earth in the form of rain. This explanation changes the mythical understanding of rain in different culture
Answer:
a) Clockwise
b) τ = 4.67 N-m
Explanation:
Given
m = 7 Kg
R = 17 cm = 0.17 m
μ = 0.4
We use the formula
τ = R*F*Sin ∅ = R*(μ*m*g)*Sin ∅
⇒ τ = (0.17 m)*(0.4*7 Kg*9.81 m/s²)*Sin 270° = - 4.67 N-m
(Clockwise)
A system that repeats to and from its mean or rest point. that executes harmonic motion. a few examples I've heard of are since the springtime a mass-spring system,a swing, simple pendulum, one more example is a steel ball rolling in a curved is this what you need or do you need three more sentences dish. to get S.H.M a body just displaced away from the resting position and of course then is released. the human body oscillates due to the reinforce that pulls it back do you need anything else answered on this and I'll answer it
