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

As 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

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.

Answer:

When the gravitational force on the Moon from the Earth = 4.00 Fm, the distance of the Moon from the Earth is 0.5·D

Explanation:

The given information includes;

The distance of the moon from the Earth = 0.25·D

The gravitational force, F, on the Moon from the Earth = 16.00 Fm

When the gravitational force on the Moon from the Earth = 4.00 Fm, the distance of the Moon from the Earth is found as follows;

From Newton's law of gravitation;

[tex]F_{1} = F_{2} =G\dfrac{m_{1}m_{2}}{r^{2}}[/tex]

At r = 0.25·D, F = 16.00 Fm

Therefore;

G×m₁×m₂ = (0.25·D)²×16.00 Fm = D²×Fm = Constant

When, the gravitational force of the Moon from the Earth = 4.00 Fm, we have;

[tex]F = 4.00 \ Fm =\dfrac{D^2 \times Fm}{r_2^{2}}[/tex]

Therefore;

[tex]r_2^{2} =\dfrac{D^2 \times Fm}{4.00 \ Fm} = \dfrac{D^2}{4}[/tex]

[tex]r_2 =\sqrt{\dfrac{D^2}{4}} = \dfrac{D}{2} = 0.5 \cdot D[/tex]

r₂ = 0.5·D

Where;

r₂ = The new distance of the Moon from the Earth

Therefore the distance of the Moon from the Earth when the gravitational force on the Moon from the Earth = 4.00 Fm is r₂ = 0.5·D.

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.

Answer:  Any push/pull on any object is made by a force of some sort.

Explanation:

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.

Given the following data:

To 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.

Answer:

Explanation:

a). Find the graph attached for the motion.

b). If a shopper walk 5.4 m westwards then 7.8 m eastwards,

   Distance traveled by the shopper = Distance traveled in eastwards + Distance traveled westwards

                                                            = 5.4 + 7.8

                                                            = 13.2 m

c). Displacement of the shopper = Distance walked westwards - Distance traveled eastwards

                                                      = 5.4 - 7.8

                                                      = -2.4 m

Therefore, magnitude of the displacement of the shopper is = 2.4 m

And the direction of the displacement is eastwards.

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) 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:

[tex]V = \frac{s(t_b) - s(t_a)}{t_b -t_a}[/tex]

Explanation:

Given;

position of the object as s(t)

The average velocity is given by;

[tex]V = \frac{s(t_b) - s(t_a)}{t_b -t_a}[/tex]

where;

s(tb) is the object's final position at time tb

s(ta) is the initial position of the object at time ta

tb is the final time of the object's displacement

ta is the initial time of the object's displacement

Answer:

Explanation:

acceleration is the change i velocity with respect to time.

Acceleration = change in velocity/time take

Acceleration = final velocity - initial velocity/time taken

Given initial velocity = 15m/s

final velocity = 25m/s

time = 6sec

Substituting the given value into the formula above to get acceleration

acceleration = 25-15/6

acceleration = 10/6

acceleration = 1.67m/s²

Hence Mia acceleration is 1.67m/s²
