Answer in the drawing. Please mark me brainliest

Answer:

p>Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.

Explanation:

u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s

by the formula, S=ut+½at².

S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation

S = 1427.6+362.404

S=1790.004m

Explanation:

But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.

The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.

The Egyptians had to overcome the force of friction while dragging the big blocks of stone and the force of gravity while uplifting the large stone structure to a greater height when building the pyramids.

Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.

The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.

Thus, while constructing the pyramids, the Egyptians had to fight against the forces of gravity and friction as they lifted the massive stone edifice to a greater height.

Answer:

D. the rate at which work is accomplished

The magnitude and direction of the resultant force are 10.0N and 101.36⁰

The sum of force along the force horizontal is expressed as:

[tex]\sum F_x=-15.0N+15cos30\\\sum F_x = -15.0N + 12.99N\\\sum F_x = -2.01N[/tex]

The sum of force along the vertical is expressed as:

[tex]\sum F_y = +10N[/tex]

Calculate the magnitude of the force:

[tex]F=\sqrt{(\sum F_x)^2+(\sum F_y)^2} \\F=\sqrt{(-2.01)^2+(10)^2} \\F=\sqrt{104.0401}\\F= 10.2N[/tex]

Hence the magnitude of the resultant force is 10.2N

Find the direction

[tex]\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{10}{-2.01}\\\theta =tan^{-1}(-4.9751)\\\theta =-78.63^0\\\theta = 180-78.63 = 101.36^0[/tex]

Hence the magnitude and direction of the resultant force are 10.0N and 101.36⁰

Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.  

Chemical potential energy​​ is position of electrons in specific substance bonds that can be broken (energizes).

:

This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.

This is electrostatic phenomenon. Chelsea see sparks as she removes her clothes from the clothes dryer because of static discharge.

Static electricity is produced by friction when two materials are rubbed together.

Why does Chelsea see sparks as she removes her clothes from the clothes dryer?

The correct answer is because of static discharge.

For instance, when a glass rod is rubbed with silk or cellulose acetate with silk, the glass will become positively charged by loosing electron to the silk whereby becoming negatively charged.

Static discharge occurs during thunder and lightning, and when combing our hair during harmattan season.

liquid - molecules are loser, faster moving and take the shape of its container

gas- fast moving molecules and take whatever shape they want (like a room or the air outside)

Explanation:

Solids: The inter-molecular attraction force is the highest and the inter-molecular distance is the least. Solids have definite shape and volume.

Liquids: The inter-molecular attraction force is less than that of solids and the inter-molecular distance is more than solids. Liquids have definite volume but no definite shape.

Gases: The inter-molecular attraction force is the least and the inter-molecular distance is the highest. Gases have no definite shape or volume.

Answer:

Explanation:

It's 9.8 m/s^2

The vector addition and kinematics of uniform motion allows to find the result for where the starting point is:

Given parameters

To find

Velocity is a vector magnitude, therefore it has direction and module, to make the addition of these magnitudes vector algebra must be used.

There are two methods for adding vectors:

In the attached we can see a diagram of the displacement of this ship. We use a Cartesian reference system and using trigonometric to decompose the velocities.

First speed

            cos 123 = [tex]\frac{v_1_x}{v_1}[/tex]  

            sin 123 = [tex]\frac{v_1_y}{v_1}[/tex]  

            v₁ₓ = v₁ cos 123

            [tex]v_{1y}[/tex] = v₁ sin 123

            v₁ₓ = 21.1 cos 123 = -11.49 mph

            [tex]v_{1y}[/tex] = 21.1 sin123 = 17.70 mph

Second speed

            v₂ₓ = v₂ cos 190

            [tex]v_{ 2y}[/tex] = v₂ sin190

            v₂ₓ = 18.2 cos 190 = -17.92 mph

            [tex]v_{2y}[/tex] = 18.2 sin190 = -3.16 mph

Now we can use kinematics of uniform motion.

            v = [tex]\frac{d}{t}[/tex]  

             d = v t

Where v is the velocity, d the distance and t the time

Let's find every distance traveled.

For first speed

x-axis

         x₁ = v₁ₓ t₁

         x₁ = -11.49  3.20

         x₁ = - 36,768 miles

y-axis  

         y₁ = [tex]v_{1y} \ t_1[/tex]

        y₁ = 17.70 3.20

        y₁ = 56.64 miles

Travel for 2nd speed

       x₂ = v₂ₓ t₂

       x₂ = -17.92 1.10

       x₂ = -19,712 miles

       y₂ = -3.16 1.10

       y₂ = - 3,476 miles

Let's find the distance traveled on each axis

x-axis

    [tex]x_{total}[/tex] = x₁ + x₂

    [tex]x_{total}[/tex] = -36,768 - 19,712

     [tex]x_{total}[/tex] = -56.48 miles

y-axis

     [tex]y_{total}[/tex] = y₁ + y₂

     [tex]y_{total}[/tex] = 56.64 - 3.476

     [tex]y_{total}[/tex] = 53,164 miles

Let's construct the total displacement vector, for the module let's use the Pythagorean theorem

       [tex]d_{total} = \sqrt{x^2 +y^2} \\d_{total} = \sqrt{56.48^2 +53.164^2}[/tex]

       [tex]d_{total}[/tex] = 77,565 miles

Let's used trigonometry for the direction

      [tex]tan \theta ' = \frac{y_{total} }{ x_{total} } \\\theta ' = tan^{-1} \frac{y_{total} }{ x_{total} }[/tex]  

      θ’= 43.3º

This angle is in the second quadrant to indicate the angle with respect to the positive side of the x-axis in a counterclockwise direction.

   θ = 180 - θ'

    θ = 180 - 43.3

   θ = 136.7º

In conclusion using the addition vectors and kinematics of uniform motion we can find the result for where the starting point is:
