The work done by the force of friction is μmgd.

The work done by the applied force is equal to the displacement of the block (d) multiplied by the component of the force parallel to the displacement. If the applied force is F and the angle between the force and the displacement is θ, then the component of the force parallel to the displacement is Fcos(θ).

Therefore, the work done by the applied force is given by dFcos(θ). The force of friction will also do work, which is equal to the displacement of the block multiplied by the force of friction. The force of friction is given by μN, where N is the normal force and is equal to the weight of the block (mg). Therefore, the work done by the force of friction is μmgd, where d is the displacement.

Correct Question :

A block of mass m is pulled along a horizontal surface by applying a force at an angle θ with the horizontal. If the block travels with a uniform velocity and has a displacement d and the coefficient of friction is μ, then the work done by the applied force is?

Answer:

90

Step-by-step explanation:

the bottom of the picture is cut off but it's 90°

becuase the picture shows you the 2 sides of the triangle r equal

the angles on the top are also equal

so that means the middle line has to be perpendicular to the base.

so Y is 90

To calculate the percent increase in airplane passenger capacity, we first need to find the difference between the current capacity (600 passengers) and the predicted future capacity (1400 passengers).

1400 - 600 = 800

Then divide this difference by the current capacity, and multiply by 100 to express the answer as a percentage.

(800/600) * 100 = 133.33

So the predicted percent increase in airplane passenger capacity is approximately 133%.

The nearest percent is 133%.

The size of the crowd is 7392 people.

The ratio is a numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

20 people fit comfortably in a 10 feet by 10 feet area.

So,

the ratio of the number of people per unit area = 20/(10 × 10) = 20/100 = 1/5

The area, A, occupied by the crowd = 7 feet × 1 mile × 1

1 mile = 5280 feet

A = 7 feet × 5280 feet × 1 = 36960 feet².

Now, number of people = 36960 x 1/5

= 7392 people.

Therefore, the required value is 7392 people.

Answer: Let's call the width of the rectangular playing field "w" and the length "l". From the problem, we know that:

l = 3w + 4 (the length is 4 yards longer than triple the width)

We also know that the perimeter of a rectangle is the sum of the lengths of all four sides, so:

P = 2l + 2w

We are given that the perimeter is 416 yards, so we can substitute that into the perimeter equation:

416 = 2(3w + 4) + 2w

Simplifying and solving for w:

16 = 6w + 8

8 = 6w

w = 8/6 = 4/3

We can now substitute that back into the equation for the length:

l = 3w + 4

l = 3(4/3) + 4

l = 4 + 4

l = 8

So the dimensions of the rectangular playing field are 4/3 yards wide and 8 yards long.

The positive interval and the negative interval for the function given is (-∞, 3) and (3, ∞).

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given function is f(x) = [tex]-2\sqrt{x+1} +4[/tex]

Positive interval of the function is the values of x when function > 0.

To get the function > 0, the value [tex]2\sqrt{x+1}[/tex] < 4.

[tex]\sqrt{x+1}[/tex] < 2

x + 1 < 2²

x + 1 < 4

x < 3

Positive interval is (-∞, 3).

Negative interval of the function is the values of x when function < 0.

To get the function value < 0

[tex]-2\sqrt{x+1} +4[/tex] < 0

[tex]2\sqrt{x+1}[/tex] > 4

[tex]\sqrt{x+1}[/tex] > 2

x + 1 > 2²

x + 1 > 4

x > 3

Negative interval is (3, ∞).

Hence the positive interval of the function is (-∞, 3) and the negative interval is (3, ∞).

To be certain that the angles created form a square inside a circle, it is important to first understand the properties of a square and a circle.

A square is a four-sided polygon with all sides of equal length and all angles of 90 degrees. This means that if we draw a square inside a circle, the four corners of the square should be tangent to the circle.

A circle is a shape with all points on the circumference equidistant from the center. This means that if we draw a square inside a circle, the distance from the center of the circle to the midpoint of each side of the square should be equal to the radius of the circle.

By verifying that the above two conditions are met, we can be certain that the angles created form a square inside the circle. Additionally, we can also check that all the four angle of the square is 90 degrees and the opposite sides are parallel.

The length of time it would have taken for both garden hoses to fill the pool would be 6.67 hours.

To solve this problem, we can use the formula:

1/rate = time

In the case of Joe's hose, the rate is 1/12 of the pool per hour. For his neighbor's hose, the rate is 1/15 of the pool per hour.

So, the combined rate is:

= (1/12) + (1/15)

= (5/60) + (4/60)

= 9/60 of the pool per hour

The segments MN, BN, and MD are the sides of a triangle.

Let AM intersect BC at point P and let AN intersect CD at point Q. Spin A about PQ to obtain E where AE = AB. We want to prove that EMN is the required triangle. For that, it is adequate to show that EM = MD and EN = BN.

Let h be the distance of A from the BCD. Then the distance of A from the line PQ is minimum h, so point E exists provided that the side length maximum is 2h. It is √(3/2) h.

We have by construction AD = AE and EP = AP.  Also, since P lies on the line BC, then PA = PD. Hence PA = PA, PD = PE, AD = AE, so PAD and PAE are congruent triangles. Hence E can also be acquired by spinning D about AP. Since M lies on AP, it gives EM = DM.

Similarly, with B and D interchanged and M and N interchanged, we get EN = BN.

The genotype must be Rr and rr because the outcome is close to the 1:1 ratio of red to white flowering plants.

According to Mendel's law of dominance, one feature in a heterozygote will mask the existence of another trait for the same attribute. The dominant allele will be exclusively expressed, as opposed to both alleles contributing to a trait.

When parents with distinct, opposing qualities are crossed, only one form of the trait manifests itself in the offspring, according to Mendel's law of dominance. Only the dominant phenotypic characteristic will be present in the hybrid offspring. The first law of inheritance is the dominance principle.

This regulation states that the first generation of offspring from purebred parents shall exhibit solely dominant features.

There will be a 1:1 ratio between the dominant and recessive traits when a heterozygous dominant parent mates with a pure recessive parent.
