If two angles of a triangle have radian measures 9 and 3 8 , find the radian measure of the third angle.

Given,

[tex]Ax =26 m/s^{2} \\Ay = 10 m/s^{2}[/tex]

As we know that slope of any line passing from (x,y) point has the slope as  [tex]\frac{y}{x}[/tex]  i.e. Tan [tex]\alpha[/tex]

Vector's Direction can be calculated by [tex]\alpha[/tex] = Tan⁻¹ [tex]\frac{Y}{X}[/tex] ,

where [tex]\alpha[/tex] is the angle with the horizontal X-axis.

therefore,

[tex]\alpha[/tex] = Tan⁻¹ [tex]\frac{10}{26}[/tex]

[tex]\alpha[/tex] = 23.375°

The vector's direction is the angle that the vector makes with the horizontal axis, i.e. with the X-axis. The direction of the vector is given by turning the angle of the vector around its tail to the east counterclockwise.

Therefore, the vector's direction for the given vector is 23.375° from the X-axis i.e. the vector Ax  = 26 m/s2, Ay= 10 m/s2 points towards the North-East direction.

Venus is observed to orbit the sun every 0.62 years so the semi-major axis of venus's orbit is 0.73 au.

Celestial mechanics uses curved trajectory objects to describe orbits, such as a planet's orbit around a star, a natural satellite's orbit around a planet, or an artificial satellite's orbit around a planet, moon, asteroid, or Lagrange point. A circle, a whole circle's revolution, or a range of experiences are all examples of what is meant by an orbit. As an example, consider the earth's orbit around the sun. An illustration of how long an orbit or full circle around takes is the 365 days it takes the earth to travel around the sun. The planets are kept in their orbits by the gravity of the Sun. Since no other force in the Solar System can halt them, they remain in their orbits.

Compared to compound 2, compound 1, the C to O double bond has more single bond characteristics.

When two atoms share two electron pairs to create two covalent connections, they create a double bond; when they share three electron pairs to create three covalent bonds, they create a triple bond.

A double bond, as opposed to a single bond, is a covalent link formed between two atoms that involves four bonding electrons. The majority of double bonds, including those in alkenes, are created when there are two carbon atoms present.

As we clearly know that in buoyancy force the weight or any other object will float over the surface of the water and this force is known as buoyancy force. The reason behind the Buoyancy force is that the object seeming lighter in water.

The Buoyancy force can be define as the upward force exerted by the fluid on any weight or any object placed in it. The Buoyancy force is directly proportional to the density of the immersed fluid. The Buoyancy force is also proportional to the volume of the object immersed in the fluid.

If the lead can be extracted with 92.5 efficiency, the mass of ore is required to make a lead sphere with a 7.00 cm radius is 17.707 kg.

To find the mass of ore, the given values are,

The radius of the lead sphere is r = 7.0 cm,

The lead can be extracted with, η = 92.5% = 0.925 efficiency.

Density is the substance's mass per unit of volume.

We know the density of lead as,

⇒ p = 11.4 g/cm³ .

The volume of the lead sphere is,

V = 4/3πr³

   = 4/3π(7)³

V = 1436.7 cm³.

Mass of the lead present in the lead sphere is,

m = p . V

    = 11.4  × 1436.7

    = 16379 g

m = 16.379 kg

From the expression of efficiency, we calculate the mass of the ore,

η = Mass of lead obtained / Mass of the ore to be taken

0.925 = 16.379 kg / Mass of the ore to be taken

Mass of the ore to be taken = 17.707 kg

now the reson for this will be

let's look in 1st part

we will use v=u+at

where v will be zero at highest pont u is 10m/s

we can take g as 10 or 9.8

so

0=10-10t

so it becomes

-10/-10=t

so 1 sec will be the answer

in 2nd part same time will be taken to come back so total time will be 2 sec

3rd part we can use v=u+at

where we have to find v, u=10 g=-10 and t=2 sec

now v=10-20 so v= -10 m/s

The resulting speed of weight B is 4m/s

Here we have the end of the cable A pulled with the speed of 12m/s

To find the speed at which block B move:

At the top of pully. We have length at A is Sa and length of B is Sb.

The length from the top pulley to the small pulley which is held by the bar that Lint we built label it H

The pulley system made of only one chord, so we need only one equation to represent the rope.

Sa +Sb +(2Sb -h) = l

When the rope is pulled at block B the whole part moves up.

Sa + 3 Sb = L+2h

In order to find the velocity, we take derivative of the above equation.

here we get

Va + 3Vb = 0

Va = 12m/s

vb = -12/3 = -4m/s

If John is 20.0 meters away from me and he is running away from me at 5.0 m/s. I sprint at 7.0 m/s to catch up. Then, I will take 10 seconds to reach him.

We know that,

Speed = Distance / Time

Time = Distance / Speed

Given that,

My speed = 7 m/s

John's speed = 5 m/s

Distance I need to cover to catch up John = ( 20 + x ) m

Distance John will cover before I catch up to him = ( x ) m

Since the time taken by both of us to reach that point is same,

( 20 + x ) / 7 = x / 5

100 + 5x = 7x

The primary indicator of an object's position and speed is its velocity. It is the distance that an object travels in one unit of time. The displacement of the item in one unit of time is the definition of velocity.

3.5(t+2) = 0.5*2.4t+2, 3.5t + 7

= 1.2t+2, 1.2t+2 - 3.5t + 7 = 0, and d1 = d2

Use the time formula, t = d/s, which states that time is equal to distance divided by speed, to solve for time.

t = 4.28s.

d = d1 = d2 = 3.5(4.28+2)

The pace at which an object moves is its speed. The distance traveled divided by the time is the calculation for speed. Distance x time equals speed. The formula for distance can be found by rearranging the formula for speed.

The cost of excavating a space of 84 ft long, 42 ft wide, and 9 ft deep is $45864

Information about the problem:

To solve this problem, we have to state the equation using the information of the problem:

Calculating the volume of the total space:

space volume = space long * space wide * space deep

space volume = 84 ft * 42 ft * 9 ft

space volume = 31752 ft3

By converting the volume from ft3 to yd3, we have:

31752 ft3 * (0,037037 yd3 / 1 ft3) = 1176 yd3

Calculating the cost of excavating the volume space:

Total cost = space volume * cost by yard3
