if a runner is moving 2.88m/s directly north and accelerating at .350 m/s^2 at an angle of -52.0. At the point in the motion where she is running directly east what is the displacement

Answers

Answer:

19.1 m, 52.0°

Explanation:

Given:

v₀ₓ = 0 m/s

v₀ᵧ = 2.88 m/s

vᵧ = 0 m/s

aₓ = 0.350 m/s² cos(-52.0°) ≈ 0.215 m/s²

aᵧ = 0.350 m/s² sin(-52.0°) ≈ -0.276 m/s²

Find: Δx and Δy

First, find time.

vᵧ = aᵧt + v₀ᵧ

0 m/s = (-0.276 m/s²) t + 2.88 m/s

t = 10.4 s

Now find the displacement components Δx and Δy.

Δx = v₀ₓ t + ½ aₓ t²

Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²

Δx = 11.7 m

Δy = v₀ᵧ t + ½ aᵧ t²

Δy = (2.88 m/s) (10.4 s) + ½ (-0.276 m/s²) (10.4 s)²

Δy = 15.0 m

The magnitude of the displacement is:

d² = Δx² + Δy²

d² = (11.7 m)² + (15.0 m)²

d = 19.1 m

The direction of the displacement is:

θ = atan(Δy / Δx)

θ = atan(15.0 m / 11.7 m)

θ = 52.0°

Calculate the average current in the lightning conductor during this time. State the formula used in your answer

Answers

Answer:

I=24,000 Amp

Explanation:

Electric Current

Is a measure of the quantity of charge Q flowing by a point in a time period of t.

The standard metric unit for the current is the Ampere, often abbreviated as Amps or A.

It can be calculated as:

[tex]\displaystyle I=\frac{Q}{t}[/tex]

The cloud generates a lightning strike that releases a charge Q=0.84 C during a time [tex]t=3.5\cdot 10^{-5}\ sec[/tex].

The current is of course, not of a constant value, but an average value can be calculated by using the above formula:

[tex]\displaystyle I=\frac{0.84}{3.5\cdot 10^{-5}}[/tex]

[tex]\boxed{I=24,000\ Amp}[/tex]

Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.

What is one characteristic of the convection inside the sun?

- Cells of circulating gasses called granules
- Thick clouds of dust and gasses
- Large cells of rising and sinking gasses
- Nuclear reactions between hydrogen atoms

Answers

Answer: 3- Large cells of rising and sinking gasses

Explanation: Hotter gas coming from the radiative zone expands and rises through the convective zone. It can do this because the convective zone is cooler than the radiative zone and therefore less dense. As the gas rises, it cools and begins to sink again. As it falls down to the top of the radiative zone, it heats up and starts to rise. This process repeats, creating convection currents and the visual effect of boiling on the Sun's surface.

A. ON
C. 9.8 N

Chanel has some cotton candy that came in a cloudy shape. She wants to make it more dense. Which describes the candy before and after Chanel manipulated it? The candy before was a cube, and the candy after was a ball. The candy before was compacted, and the candy after was fluffy. The candy before was fluffy, and the candy after was compacted. The candy before was a ball, and the candy after was a cube.

Answers

Answer:

The candy before was fluffy, and the candy after was compacted.

Explanation:

By definition, something that is fluffy is something very soft, and when you talk about fluffy food (e.g. cakes, cotton candy) it is food that has a lot of air in it. In this case, the cotton candy originally had the shape of a cloud and was not dense, therefore, it was fluffy.

Something that is compact, it something that is dense, solid and generally small. Since Chanel wanted her cotton candy to be more dense, she compacted it .

Frictional force. hope this helps have a good day

Answer:

frictional force

Explanation:

Friction always acts to oppose any relative motion between surfaces. For the simple example of a book resting on a flat table, the frictional force is zero. There is no force trying to move the book across the table, so there is no need for a frictional force because there is nothing for the frictional force to oppose.

a car on a circular track accelerates from rest. the radius of the track is 0.30km and the magnitude of the constant angular acceleration is 4.5x10-3 rads/s squared. find the centripetal acceleration of the car when it has completed half of a lap. ​

Answers

Answer:

The centripetal acceleration of the car is 50.4 m/s²

Explanation:

Given;

radius of the track, r = 0.3km = 300 m

constant angular acceleration, α = 4.5 x 10⁻³ rad/s²

during half of a lap, θ = π

Determine time of motion

θ = ωt + ¹/₂αt²

π = 0 + ¹/₂αt²

t² = 2π / α

t² = ( 2 x 3.142) / (4.5 x 10⁻³)

t² = 1396.44

t = √1396.44

t = 37.369 s

Determine the angular velocity

[tex]\omega_f = \omega_i + \alpha t\\\\\omega_f = 0 \ + \ 37.369*4.5*10^{-3}\\\\\omega_f = 0.168 \ rad/s[/tex]

Determine the centripetal acceleration of the car

[tex]\alpha _c = \omega^2 r\\\\\alpha _c = 0.168*300\\\\\alpha _c =50.4 \ m/s^2[/tex]

Therefore, the centripetal acceleration of the car is 50.4 m/s²

Density

The density of an object of mass m and volume V is given by:

[tex]\displaystyle d=\frac{m}{V}[/tex]

We are given the following densities:

Gold: 19.3 gr/cm3

Silver: 10.5 gr/cm3

With the data provided in the table, we can confirm which of the three columns corresponds to gold, silver, or a mix of both.

Calculating the first density: m1=1,930 gr, V1=100 cm3

[tex]\displaystyle d1=\frac{m1}{V1}[/tex]

[tex]\displaystyle d1=\frac{1,930}{100}[/tex]

[tex]d1=19.3\ gr/cm^3[/tex]

This crown is made of gold

Calculating the second density: m2=1,930 gr, V2=184 cm3

[tex]\displaystyle d2=\frac{m2}{V2}[/tex]

[tex]\displaystyle d2=\frac{1,930}{184}[/tex]

[tex]d2\approx 10.5\ gr/cm3[/tex]

This crown is made of silver

Calculating the last density: m3=1,930 gr, V3=150 cm3

[tex]\displaystyle d3=\frac{m3}{V3}[/tex]

[tex]\displaystyle d3=\frac{1,930}{150}[/tex]

[tex]d3\approx 12.9 gr/cm^3[/tex]

Since the value of the density is between gold and silver, this crown is a mixture.
