Can an eagle reach exosphere through flying?

Answer: The resultant displacement vector is 5.6km

The resultant displacement vector of the hiker is equal to 5.6 km.

The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.

The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.

Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.

The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (5.0)² + (2.5)²

AC² = 25 + 6.25

AC = 5.59 km ≈ 5.6 km

Therefore, the displacement of the hiker is 5.6 Km.

The radius of each jawbreaker is approximately 0.68 cm.

where

r = radius

Therefore,

23 g  = 32.3 cm³

0.94 g  = ?

cross multiply

volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³

Therefore,

volume of each jawbreaker = 4 /3 πr³

1.32 = 4 / 3 × 3.14 × r³

r³ = 1.32 /4.18666666667

r³ = 0.31533683707

r = ∛0.31533683707

r = 0.680651651 = 0.68

Therefore, the radius of each jawbreaker is approximately 0.68 cm.

The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics. Kinematics equations are a set of equations that can derive an unknown aspect of a body’s motion if the other aspects are provided.

given

speed = 5 m/s

time = 1.5 seconds

using

v = u + at

Based on the data provided;

The formula for calculating density is given as:

From the formula above;

mass = density × volume

also, volume = area × height

Therefore,

mass = density × area × height

Calculating for the height of the liquid:

Height, L = 90.8 / (0.86 × 6.08)

L = 17.2 cm

The pressure due to a liquid is calculated using the formula below:

where;

h is height = 17.2 cm = 0.172 m

P is density = 0.86 g/cm^3 = 860 kg/m^3

g is acceleration due to gravity = 9.8 m/s^2

Pressure = 860 kg/m^3 × 0.172 m × 9.8 m/s^2

Pressure = 1449.616 N/m

Here it's given that the weight of the box is 4N and it slides across a rough table for a distance of 2m . And we are interested in finding out the work done by the weight of the block. Firstly we know that , Work done is ,

[tex]\rm\longrightarrow \pink{ Work\ = \ F.s = |F||s|cos\theta} [/tex]

where

Therefore ,

[tex]\rm\longrightarrow Work = (4N)(2m)(cos\theta) [/tex]

Here the angle between the displacement and force is 90° , and value of cos90° is 0 , therefore,

[tex]\rm\longrightarrow Work = 8N-m (0)\\[/tex]

[tex]\rm\longrightarrow \underline{\boxed{\rm\blue{Work = 0 }}}[/tex]

The work done by the weight of the box is zero. The correct answer is zero. The correct option is (E).

Given:

Weight of the box = 4.00 N (acting downward)

Distance = 2.00 m

The angle between force and displacement, θ = 90°

Using the formula for work:

Work (W) = Force × Distance × cos(θ)

Since the angle θ is 90 degrees and cos(90 degrees) = 0.

The work done by the weight of the box is:

W = Force × Distance × cos(90)

W = 4.00 × 2.00 × 0

W = 0 J

Therefore, the work done by the weight of the box is zero. The correct option is (E).
