Write a explanation explaining why red is a beautiful color is not a hypothesis
Answer:
Please find the explanation below
Explanation:
A hypothesis in science is a testable explanation that is yet to be tested via experimentation. It is a predictive statement or suggested solution to an observation. A hypothesis aims at finding a possible explanation/answer to a question, which is subject to testing. One important aspect of formulating a hypothesis is that it tends to connect the independent variable with the dependent/measurable variable.
The statement "RED IS A BEAUTIFUL COLOR" cannot be considered a hypothesis because it does not aim to answer a question that can undergo experimental testing. This statement can not be measured via experimentation. The statement is not a possible answer to a question but rather a personal opinion about something.
what acceleration of a 45 kg mass pushed with 15 N of force?

two teams are playing tug of war. Team A pulls to the right with a force of 450 N. Team B pulls to the left with a force of 415 N
Answer:
team A - team B = 450 N - 415 N
= 35 N
Explanation:
net force on the rope is 35 N and the direction is towards A.since the two teams are pulling away from each other with the given forces, the net force can be calculated by subtracting the forces.
The net force on the rope is 35N in right direction
What is Net Force? The net force is the vector sum of forces acting on an object,How to calculate the Net force?The force applied by Team A is 450N to the right (Given)The force applied by Team B is 415 N to the left (Given)We need to find the Net force applied on the rope and the directionAs We know that ,
[tex]F_{net} = F_1+F_2[/tex]
Now as The direction of the Team A is right so the Force applied will be positive, that is 450N
Simultaneously , The direction of Team B is left so the Force applied will be negative , that is -415N
Here,
F1 = 450N
F2 = -415N
[tex]F_{net} = F_1+F_2[/tex]
= 450+ (-415N)
= 450-415
=35N
Hence the net force applied is 35N and as the net force is positive the direction will be right

A stone falls freely from rest for 8.0 s.
a. Calculate the stone's velocity after 8.0 s.
b. What is the stone's displacement during
this time?
a) The acceleration that the stone has is the gravitational acceleration and it is always the same (Actually not but assumed to be so)
The gravitational acceleration is 9.81 m/s²
Since this acceleration is always constant, we can use the formula of V = g × t, where V is velocity, g is the gravitational acceleration and t is time.
Let's use this formula: V = g × t = 9.81 × 8.0 = 78.48 m/s
b) Displacement in free falls is calculated by the formula of d = 1/2 × g × t², which is actually derivated from average velocity.
If we use the formula, d = 1/2 × 9.81 × 8² = is found to be 313.92 m

Answer:
The average speed of her is 2 m/s.
The acceleration for the entire trip is 0.2 m/s²
Explanation:
Given that,
katie measured the distance her friend morgan ran on a straight track every 2s.
According to given chart,
We need to calculate the average speed
Using formula of average speed
[tex]v_{avg}=\dfrac{D}{T}[/tex]
Where, D = total distance
T = total time
Put the value into the formula
[tex]v_{avg}=\dfrac{20}{10}[/tex]
[tex]v_{avg}=2\ m/s[/tex]
We need to calculate the acceleration for the entire trip
Using equation of motion
[tex]v=u+at[/tex]
[tex]2=0+a\times10[/tex]
[tex]a=\dfrac{2}{10}[/tex]
[tex]a=0.2\ m/s^2[/tex]
Hence, The average speed of her is 2 m/s.
The acceleration for the entire trip is 0.2 m/s²

Mad scientists looked at the growth of claw size in mutant lobsters due to drinking different amounts of seawater contaminated with Pepsi. Independent Variable: Dependent Variable: Controlled Variable:
Answer:
Dependent Variable: growth of claw size in mutant lobsters
Independent variable: different amounts of seawater contaminated with Pepsi
Controlled variable: Mutant Lobsters
Explanation:
A dependent variable is one that depends on another factor to get it's result.
An independent variable is one that doesn't rely on another factor/variable to derive it's result.
A controlled variable is one which is constant and remains unchanged throughout the course of the experiment/investigation. Which means it verifies the behavior between the dependent and independent variables.
Now, in the question, the growth of claw size in the mutant lobsters depends on the different amounts of seawater contaminated with Pepsi.
Thus growth of claw size in mutant lobsters is a dependent variable while different amounts of seawater contaminated with Pepsi is an independent variable.
The mutant lobsters would be used throughout the investigation to know the relationship between the dependent and independent variable and wouldn't be changed. Thus, they are controlled variable.

A billiard ball moves with 3 kg⋅m/s of momentum and strikes three other billiard balls. What is the total momentum of the balls after the collision?
(1 point)
more than 3 kg⋅m/s
3 kg⋅m/s
It depends on the mass of each ball.
less than 3 kg⋅m/s
A billiard ball moves with 3 kg⋅m/s of momentum and strikes three other billiard balls that have been just sitting there at rest and not moving.
The total momentum of all four balls after the collision is 3 kg⋅m/s, because momentum is not created or destroyed. The total amount of it after an event is the same as the total amount of it before the event.
The momentum of the billiard balls after the collision is 3 Kgm/s.
Let the billiard ball be B.Given the following data:
Momentum B = 3 Kgm/sTo find the momentum of the balls after the collision:
Momentum is simply a multiplication (product) of the mass of an object with its velocity. Also, momentum is a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex]Momentum = Mass[/tex] × [tex]Velocity[/tex]
[tex]Total \; momentum = Momentum \; B + Momentum \;of \;the \;other\; balls.[/tex]
Since the other billiard balls were at rest (not experience any motion), there velocities would be zero (0) m/s.
Substituting the given values, we have:
[tex]Total \; Momentum = 3 + 0[/tex]
Total momentum = 3 Kgm/s.
Therefore, the momentum of the billiard balls after the collision is 3 Kgm/s.
