Enzo investigated the effect of different types of fertilizers on the growth of bean plants. He hypothesized that fertilizer B would result in the greatest amount of growth. However, the results showed that the control plants without fertilizer had the greatest growth. Why was Enzo's data still valuable even though it did not support his hypothesis?
Answer:
The answer is "In this information, Enzo will be confident that if any fertilizer is required only for plants".
Explanation:
The Beans plants were members of the group of legumes. Legume flowering plant under which the roots form nodules. These nodules require a specific bacterium called bacteria, which fix nitrogen. Its bacterium transforms nitrogen from the atmosphere into the soil's nitrate. Consequently, for some of its growth, beans do not require fertilizer.
Find the horizontal and vertical displacement comments of 145m displacement of a superhero that flies from the top of a building at an angle of 28 degrees below the horizontal
Answer:
The horizontal and vertical displacement is 128.02 m and 68.07 m respectively.
Explanation:
Displacement, d = 145 m
The top of a building at an angle of 28 degrees below the horizontal
We need to find the horizontal and vertical displacement.
For horizontal displacement,
[tex]D_x=d\cos\theta\\\\D_x=145\times \cos(28)\\\\D_x=128.02\ m[/tex]
For vertical displacement,
[tex]D_y=d\sin\theta\\\\D_y=145\times \sin(28)\\\\D_y=68.07\ m[/tex]
So, the horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

Watching your mother bake bread, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wonder whether the amount of sugar used will affect the size of the bread. That is, if you add more sugar, the size of the bread will be larger. Your mother’s recipe calls for 60 grams of sugar to produce a loaf of bread about 1260 cm3 what is the problem
Answer:
The question is not complete, below is the completed question:
Watching your mother bake bread, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wonder whether the amount of sugar used will affect the size of the bread. That is, if you add more sugar, the size of the bread will be larger. Your mother’s recipe calls for 60 grams of sugar to produce a loaf of bread about 1260 cm3. What is the independent and dependent variables?
Answer:
independent variable: amount of sugar used
Dependent vairable: size of bread
Explanation:
In a scientific experiment, there are two main types of variables; independent and dependent variable:
Independent variable: This is the variable that is completely under the control and manipulation of the experimenter. The values of this variable can be varied at will, and the effect of the variation affects the dependent variable. In this example, the independent variable is the amount of sugar used, because the amount of sugar used is determined by the baker.
Dependent variable: The dependent variable is the variable that changes as a result of the manipulation of the independent variable. It is not directly under the manipulation of the experimenter, and it is the variable that the experiment seeks to study. In this example, the size of the bread is the dependent variable because it depends on the amount of sugar used.

Calculate the following sum, and express the answer in meters. Follow the rules for significant figures.
(25.873 km) + (1024 m) + (3.0 cm) =
Answer:
26897.3 m
Explanation:
1 km = 1000 m
1 cm = 0.01 m
so the calculation will be
25873 m + 1024 m + 0.03 m= 26897.3 m
The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.
What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,
(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)
1 kilometers = 1000 meters
1 meter =100 centimeters
(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)
= 26897.03 centimeters
Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.

If a sled is being pulling on the ground toward the right with a force of 100 N and friction is acting on it to the left with a force of 85 N, what is the net force
of the sled?
O 15 N to the left
15 N to the right
185 N to the right
185 N to the left
Answer:
15 N to the right.
Explanation:
100 N to the right -->
85 N to the left <--
So therefore in order to find the net force of where the sled is being dragged towards is 100 N - 85 N = 15 N.
So the sled is moving towards the right of 15 N.
An Inuit pushes a loaded dogsled with a mass of 600.0 kg over the frictionless surface of hard-packed snow. He exerts a constant 150.0 N force as he does so.
What is the sled's acceleration?
Given parameters:
Mass of Dogsled = 600kg
Force = 150N
Unknown:
Acceleration of the sled = ?
Solution:
Force is a physical quantity and can be expressed as a product of mass and acceleration.
Force = mass x acceleration
Since acceleration is unknown, we input the parameters and solve for it;
150 = 600 x acceleration
Acceleration = [tex]\frac{150}{600}[/tex] = 0.25m/s²
The acceleration of the sled is 0.25m/s²
Carsten is walking down the street while maintaining a constant velocity of 5.0 m/s west. At time t = 0.0 s, Carsten is 250 m west of point A. What is his displacement from the starting position at 60.0 s? *
Answer Format: # units direction
Answer:
550 meters west
Explanation:
Givens: Inital velocity/vi= 5.0m/s, time/t=60.0s, acceleration/a= 0 because a constant velocity means 0 acceleration, inital position/xi=250m
Unknown: final position/xf=?
Formula: xf=xi+vi(t)+1/2at^2
xf=250m+5.0m/s(60.0s)+1/2(0)(60.0s)^2
xf=250m+300m
xf=550m west
its still west because he never chhanged direction therefore his postion kept increasing.
