[3]
i) Find the magnitude of the resultant force on the block.
ii) Find the direction of resultant force with respect to A and B.

Answers

Answer:

1 N

Explanation:

1) You'll just have to sum the force vectors, and since they are opposite, you'll calculate the difference of their magnitudes, in absolute value.

Ftot = |F1 - F2| = 6N - 5N = 1N

2)The direction will be the same as the greater force's direction.

How does NaOH form a basic solution when it dissolves in water

Answers

It decomposes into CH3COO- and H+ when dissolved in water. The H+ ions react with the water molecules to generate H3O+, making the solution acidic. When NaOH is added to water, it separates into Na+ and OH-. The sodiums have little effect on the solution, but the hydroxyls make it more basic.

When NaOH is added to water, it separates into Na+ and OH-. The hydroxyls make it more basic.

What is basic solution?

A basic solution is an aqueous solution containing more OH⁻ ions than H⁺ ions.

When NaOH as a solute is mixed into the solvent like water, it separates NaOH into Na+ and OH-. The sodium ions Na⁺ have little effect on the solution, but the hydroxyls OH⁻ ions makes the solution more basic.

Thus, NaOH form a basic solution by the presence of OH⁻ ions  into it.

Your father bought you a pair of shoes. When you wore the shoes you realized there was a problem. The shoes were too long. Why might such prblm arise and how can it be mitigated?
Please answer it soon as possible ​

Answers

Answer: This problem may arise when your father never bought a shoe before. A male is bad at buying accesories and guessing the size, so the mother should have bought a pair of shoes. Or it can also be that your father has a short term memory or that he never knew the size of your feets. The feet might also have irregular growth for which it grows more than the normal size but such cases are rare to be seen.

You can prevent this by going with your father and selecting the shoe of your size. Or you can simply send your mother to buy it for you instead. Or another perfect choice could be is that you just dont ever send your father to buy anything for you or just never buy a pair of shoes. Wear the shoes that you always did or buy it yourself since your the one who is supposed to know the size of your feets. Another possible solution could be that you can make use of the money by gifitng them to someone close to you.

What’s the physics of a football

Answers

Answer:

There are many forces involved in the game of football. These are: Force of Gravity, Normal Force, Force of Friction, and Applied Force. Force of Gravity applies to football when the football is thrown or kicked, when a player jumps in the air to avoid a tackle or catch a ball, and is constantly being applied.

Explanation:

How physics is used in football?

When you throw a football across the yard to your friend, you are using physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The farther away your friend is, the harder you have to throw the ball, or the steeper the angle of your throw.

Annie comes to a sudden stop to avoid hitting a deer crossing the road at night. As she hits the breaks, her speed drops from 12 m/s to zero in 1.5 seconds.(p1) How far did she travel during that time? (p2)What was her average acceleration?

Distance(p1)
9 m
8 m
10 m
13.5 m

Acceleration(p2)
6 m/s2
8 m/s2
12 m/s2
16 m/s2

Answers

Answer:

1. around 22m

Explanation:

Annie traveled 9 meters during that time. Her average acceleration was -8 m/s².

Annie's initial speed was 12 m/s.

Her final speed was 0 m/s.

The time it took her to stop was 1.5 seconds.

Therefore, the distance she traveled during that time is:

distance = (initial speed + final speed)/2 * time

= (12 m/s + 0 m/s)/2 * 1.5 seconds

= 9 meters

Annie's average acceleration is calculated by dividing her change in velocity by time it took for that change to occur.

In this case, her change in velocity is from 12 m/s to 0 m/s, which is a decrease of 12 m/s.

The time it took for this change to occur is 1.5 seconds.

Therefore, Annie's average acceleration is:

acceleration = change in velocity / time

= -12 m/s / 1.5 seconds

= -8 m/s²

The negative sign indicates that Annie was slowing down.

If the western component of the wind is half of the south, what is the angle of the wind with the south?

Answer this question in details!

Answer is 26.57 or tan^-1 (1/2) or cot^-1 (2)

no links !​

Answers

Answer:

This above a triangle that models our situation.

Explanation:

We have a two componens., since we have a western componet and southern component. One travel in a southern direction. and the other travel in the west.

Let the component that travel in the south be the length of a.

According to the problem, the westard component is half of that so let that length be a/2.

Now we must find the angle of the wind in the South.

This means that what is angle that is opposite of the western componet because that angle is the most southward angle. So know we apply the tan property.

[tex] \tan(x) = \frac{opp}{adj} [/tex]

Our side opposite of the angle we trying to find is the western component and the side adjacent to it is the southern component. Also remeber since western and Southern negative displacements, we have

[tex] \tan(x) = \frac{ - \frac{a}{2} }{ - a} [/tex]

[tex] \tan(x) = - \frac{a}{2} \times - \frac{1}{a} = \frac{1}{2} [/tex]

Now we take the arctan or inverse tan of 1/2.

[tex] \tan {}^{ - 1} ( \frac{1}{2} ) = 26.57[/tex]

Based on the information about vector components and graph provided, the angle of the wind with the south is 26.57°.

What are the values of the western and southern component of the wind?

The western and southern component have a negative displacement as shown in the graph.

Let the southern component be -x

The western component is half of -x = -x/2

What is the angle of the wind with the South?

Since the angle is with the south, the trigonometric ratio to be used to find the angle is:

Tan θ = opp/adj

Tan θ = -×/2 /-x

Tan θ = 1/2

θ = tan^-1(0.5)

θ = 26.6°

Therefore, angle of the wind with the south is 26.57°.

How do you find the final velocity of two objects colliding when you only have the mass and initial velocity of both objects

Answers

Answer:

We are required to analyze the conservation of kinetic energy in a perfectly inelastic collision.

kinetic energy:K=1/2mv²

momentum:p=mv

Explanation:

Using the equations for final velocity in terms of masses and initial velocity for a perfectly inelastic collision, work out the final kinetic energy. Calculate the initial kinetic energy and show that kinetic energy is not conserved. Use variables, no numbers

You need to follow law of conservation of energy

Energy is neither created nor destroyed

We know

Kinetic Energy=mass(Velocity)^2

You may use momentum formula mass×velocity

In both you need to form equations then solve for final velocity

according to newton's third law, of a sledgehammer hits a wall with a force of 1000 n, how much force does the wall hit the sledgehammer? a - 1000 n b 1000 n c 0 n d 500 n

Answers

The correct option is A: the force exerted on the wall by the sledgehammer is  - 1000 N

Newton's third law

Newton's third law of motion states that for every action or force, there is an equal but oppositely directed force.

Application of the newton's third law

Force with which the sledgehammer hits the wall = 1000 N

From the Newton's third law, an equal but oppositely directed force is exerted on the sledgehammer by the wall.

Thus, the force exerted by the sledgehammer on the wall = -1000 N

The negative sign indicates that the force acts in a direction opposite to that of the sledgehammer.

Thus, the correct option is A: the force exerted on the wall by the sledgehammer is  - 1000 N

when a rigid body rotates about a fixed axis, all the points in the body have the same

Answers

Hi there!

[tex]\large\boxed{\text{Angular acceleration.}}[/tex]

For a rigid body rotating about a fixed axis, its angular characteristics ⇒ angular acceleration and velocity are constant throughout.

However, its LINEAR velocities/accelerations differ because of the following relationships:

v = ωr

a = αr

Thus, a point closer to the axis of rotation has a smaller linear velocity or acceleration compared to a point along the edge.

Helen Bedru is the assistant controller of Cotton Cravat Co., a subsidiary of HG automotive, which manufactures tailpipes, mufflers, and catalytic converters at several plants throughout Ethiopia . Because of pressure for lowerselling prices, Cotton Cravat Co. has had disappointing financial performance in recent years. Indeed, Helen is aware of rumblings from corporate headquarters threatening to close the plant. One of Helen's responsibilities is to present the plant's financial plans for the coming year to the corporate officers and board of directors. In preparing for the presentation, Helen was intrigued to note that the focal point of the budget presentation was a profit-volume graph projecting an increase in profits and a reduction in the break-even point. Curious as to how the improvement would be accomplished, Helen ultimately spoke with Kiruvel Mesfin, the plant manager. Kiruvel indicated that a planned increase in productivity would reduce variable costs and increase the contribution margin ratio. When asked how the productivity increase would be accomplished, Kiruvel made a vague reference to increasing the speed of the assembly line. Helen commented that speeding up the assembly line could lead to labor problems because the speed of the line was set by union contract. Kiruvel responded that he was afraid that if the speedup were opened to negotiation, the union would make a big "stink" that could result in the plant being closed. He indicated that the speedup was the "only way to save the plant, our jobs, and the jobs of all plant employees." Besides, he did not believe employees would notice a 2 or 3 percent increase in speed. Kiruvel concluded the meeting observing, "You need to emphasize the results we will accomplish next year, not the details of how we will accomplish those results. Top management does not want to be bored with details. If we accomplish what we propose in the budget, we will be in for a big bonus."
