Answer:
Therefore the mass of the object is 56.78 kg.
Step-by-step explanation:
Mass: Mass of an object is physical property.Mass of an object can't change with respect to place.
The S.I unit of mass is Kg
But the weight of an object changes with respect to place.
Weight= mass× gravity
The gravitational force varies place to place.
For this reason the weight of an object is not constant.
The value of g is 9.8 m/s².
Unit of weight:
Weight = mass × gravity
=Kg×m×s⁻²
=N
Given, weight= 557 N , g= 9.81 m/s² and mass=?
Weight = mass × gravity
⇒557= mass× 9.81
⇒mass= 56.7787≈56.78
Therefore the mass of the object is 56.78 kg.
We are given with two points of a parabola : v (5,-1) and f (3,-1). In this case, we can see that the parabola is opening to the left which means the standard form to be followed is -4a(x-h) = (y-k)^2. a is equal to 2. substituting, -4*2 (x-5) =(y+1)^2. This is equal to -8 (x-5) = (y+1)^2
Answer:
the answer is 3
Step-by-step explanation:
because 16-13 leaves you with 3
Answer:
Fertilizer puts nitrogen into the soil, so using fertilizer puts more nitrogen into the carbon cycle.
When you use fertilizer, its because a certain plant you are planting uses all the nitrogen in the soil, so it won't grow next time. Too much fertilizer, though, would burn up your plant (not literally). Some plants put their own nitrogen into the soil. I can't think of one off the top of my head, but I believe potatoes do. Anyways, this is where crop rotation came into play.
Things like corn take a lot of nitrogen, so the next time you had to plant whatever plant potatoes, which again may be wrong, in order to get nitrogen for the corn to grow next season. Today we have fertilizer, so we can give them nitrogen while they grow, instead of putting in other plants, taking more time.
So really, it doesn't do much, because your plant takes all the nitrogen that the Fertilizer adds.
