Answer:
160N
Explanation: When 80kg mass is one group . It's reaction force acting on a ground.
Weight of the object = 80*10
= 800 N
Here we are given cofficient of static friction its 0.2. It should be smaller than 1
Friction force = Reaction * Friction Cofficient
Reaction = 800N ( Considering Vertical Equilibrium )
F = 800* 0.2
F = 160N
Answer:
The wavelength is 754.2 nm.
Explanation:
Given that,
Diffraction pattern y= 1.35 mm
Width = 0.838 mm
Distance D= 75 cm
We need to calculate the wavelength
Using formula of diffraction pattern
Where, y = diffraction pattern
m = order
d = width
D = distance
Put the value into the formula
Hence, The wavelength is 754.2 nm.
Answer:
Producers
Consumers
Decomposers
Explanation:
The three categories in which every living thing in a forest ecosystem can be sorted into are producers, consumers and decomposers.
The producers as the name implies manufactures food for the whole of the ecosystem. They take inorganic materials from the environment and convert them into useful food materials. All plants are producers and some micro-organisms.
Animals are consumers and they take up the produced food for their own nourishment and life activities.
Decomposers recycles materials in the ecosystem by converting wastes generated by producers and consumers into useful products that returns to the atmosphere or replenishes soil nutrients.

Answer:
If the population were to INCREASE land use would also INCREASE, if the human population DECREASED so would land use because there wouldn’t be as many people to using it. hope i helped
