Answer:

Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.

How much time would it take for an airplane to reach its destination if it traveled at an average velocity of 820 km/hr NE for a

Vladimir79 [104]

Answer:

Time, t = 6.34 hours.

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

$Velocity = \frac{displacement}{time}$

Therefore, making time the subject of formula;

$Time = \frac{displacement}{velocity}$

Given the following data;

Displacement = 5200km

Average velocity = 820km/hr

Substituting into the equation, we have;

$Time = \frac{5200}{820}$

Time = 6.34 hours.

<em>Hence, it would take 6.34 hours for the airplane to reach its destination. </em>

Using the method of dimension, derive an expression for the velocity of sound waves. assume that the velocitu depends on:

Soloha48 [4]

Answer:

v = K √(E / ρ)

Explanation:

Modulus of elasticity has units of N/m², or kg/m/s².

Density has units of kg/m³.

Velocity has units of m/s.

If we divide modulus of elasticity by density, we can eliminate kg:

E / ρ = [kg/m/s²] / [kg/m³]

E / ρ = [m²/s²]

Taking the square root gets us units of velocity:

√(E / ρ) = [m/s]

Multiply by the constant K:

v = K √(E / ρ)

As an aid in working this problem, consult Concept Simulation 11.1. The volume flow rate in an artery supplying the brain is 3.5

klemol [59]

Answer

given,

flow from the artery = 3.5 x 10⁻⁶ m³/s

Radius of artery = 5.80 x 10⁻³m

area = π R²

= π x (5.8 x 10⁻³)²

= 1.06 x 10⁻⁴ m²

$v = \dfrac{Q}{A}$

$v = \dfrac{3.5 \times 10^{-6}}{1.06 \times 10^{-4}}$

v = 0.033 m/s

b) new velocity of flow

Radius = R' = R/4

A V = A' V'

R² V = R'² V'

R^2 V = (\dfrac{R}{4})^2 V'

V' = 16 V

V' = 16 x 0.033

V' =0.528 m/s
