What is the velocity at 10 seconds? PLEASE HELP!!!!!

Answer:

The reading will be the same.

Explanation:

Mass does not depend upon anything and it remains the same anywhere. What changes is the weight of the body because it depends upon gravity and is different at different places.

Giving me the brainest will be helpful.

The reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.

A weighing scale known as a balance is a device used to quantify weight or mass. The classic scale is made up of two plates or bowls that are suspended at equal distances from a fulcrum.

A person with a mass of 70kg is standing on a scale in an elevator suddenly the cable snaps, The reading on the scale during free-fall will be the same as the initial elevator condition.

Hence the reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.

To solve this, we must be knowing each and everything related to atmosphere. Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The atmosphere is more than simply the beautiful sky above. The atmosphere is made up of numerous levels of gases that surround the planet.

The word "atmo," which meaning vapor, smoke, or fog in Greek, is the source of the atmosphere's name. "Sphere" comes from the Greek word sphaira, which meaning ball. The term "atmosphere" refers to a vapor ball. Thermosphere is the layer of the atmosphere has no definite outer limit. The thermosphere is located between 53 miles (85 kilometers) and 375 mile (600 kilometers).

Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The exosphere is the layer of the atmosphere that has no clear outer limit. The exosphere is the Earth's atmosphere's outermost layer, extending from the top of the thermosphere to the edge of space.

The exosphere, unlike the other layers of the atmosphere, gradually transitions into the vacuum of outer space with no clearly defined border.

The density and spread out of gas molecules in the exosphere are exceedingly low.

This area is made up mostly of relatively light gases like hydrogen and helium, and it is where satellites and other spacecraft circle the Earth.

Thus, the progressive reduction in density as the atmosphere merges into space accounts for the lack of a well-defined outer boundary.

Answer:  In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.

Explanation:

Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.

The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

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:

Answer:

the order is written in the attached image

Explanation:

The second stone hits the ground exactly one second after the first.

The distance traveled by each stone down the cliff is calculated using second kinematic equation;

[tex]h = v_0_yt + \frac{1}{2} gt^2[/tex]

where;

[tex]h = \frac{1}{2} gt^2[/tex]

The time taken by the first stone to hit the ground is calculated as;

[tex]t_1 = \sqrt{\frac{2h}{g} }[/tex]

When compared to the first stone, the time taken by the second stone to hit the ground after 1 second it was released is calculated as

[tex]t_2 = \sqrt{\frac{2h}{g} } + 1[/tex]

[tex]t_2 = t_1 + 1[/tex]

Thus, we can conclude that the second stone hits the ground exactly one second after the first.

"Your question is not complete, it seems be missing the following information;"

A. The second stone hits the ground exactly one second after the first.

B. The second stone hits the ground less than one second after the first
