g The ant has traveled 10 cm horizontally and 6 cm vertically from its starting point on a twig with a slope of 0.5. If this is the only information the ant has, what function best approximates the geometry of the twig at the point the ant is on? b) The ant can use its model of the environment to plan its movements. In particular, it wants its next step to take it no higher than 0.1 cm above its current location. How far can the ant travel horizontally and still accomplish this?

Answers

Answer:

a)  a right triangle,  b)   x = 0.167 m

Explanation:

a) It is asked to find which geometry figure describes the movement of the ant.

Let's use trigonometry with the angles measured in radians

             tan θ = y / x

             tan θ = 6/10  

             θ = tan⁻¹ 0.6

             θ = 0.54 rad

this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle

b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea

            x = 0.1 / tan 0.54

            x = 0.1668 m

            x = 0.167 m

Explain the law of inertia in your own words.

Answers

A

An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.

Explanation:

Answer:

Law of inertia is Newton's first law of motion..

Explanation:

It means that a body will tend to be in it's motion or tend to move in a straight line unless any external force is acted upon it..

Eg: while you are travelling in bus.. If breaks are suddenly applied your body falls forward because you were in motion with bus but it tries to be in motion when breaks are applied...

How do I solve this arithmetic sequence?

Answers

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

I lift a 20kg ball up 2.5 meters off the ground on Earth.

-Earth’s gravitational acceleration is about 9.8 m/s2.

How much gravitational potential energy does the ball have at this point? _____________
How much work did I do lifting up the ball? _____________________________________
If I lift the same ball the same distance on the Moon, then how much gravitational potential energy will it have? (Moon’s Gravity = 1.6 m/s2) ____________________________________

Answers

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.  

How much work did I do lifting up the ball?  As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

Answers

Answer:

The crown is not made of solid gold.  

Explanation:

Density ρ = M/V.  M and V are given.

The density of the crown is (0.5 kg)/(185 cm3) * (106 cm3)/(1 m3) = 2.7*103 kg/m3.

The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?

A. 1/2 m

B. 1 m

C. 2 m

D. 2 seconds

E. none of these

Answers

Answer:

Suppose that the wave equation is:

f(x) = A*cos(k*x)

The wave is in phase for two points x₁ and x₂ if:

f(x₁) = f(x₂)

And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:

wavelength = x₂ - x₁

In this case, we know that the wave is in phase for two points that are 2 m apart.

Then we can use the points:

x₁ and x₂ such that:

x₂ = x₁ + 2m

We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.

Then the wavelength will be:

wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m

Then the wavelength is 2m.

The correct option is C.

So the more views the woman’s and men’s soccer gets the more they get paid . In which in a way that’s sets the woman’s pay way lower compared to the men’s.
