Jack and Nas decided to have a race from their houses to the park to know who runs the fastest. Jack whose house is 15 kilometer

Anettt [7]

Answer:

the Jack speed is greater than the Nas speed

v₁ = 2.08 m / s > v2 = 1.85 m / s

Explanation:

For this exercise we can find the average speed of each of the boys, the average speed is defined as the displacement in the time interval

v = x / t

Jack.

It tells us that it travels x = 15 km in a time of t = 2 h

let's reduce the magnitudes to the SI system

x = 15 km (1000 m / 1 km) = 15 10³ m

t = 2 h (3600 s / 1 h) = 7200 s

let's calculate

v₁ = 15 10³/7200

v₁ = 2.08 m / s

Nas travels a distance of x = 10 km in a time of t = 1.5 h

x = 10 km = 10 10³ m

t = 1.5 h (3600s / 1h) = 5400 s

let's calculate the speed

v2 = 10 10³/5400

v2 = 1.85 m / s

From these results we can see that the Jack speed is greater than the Nas speed

A tsunami, an ocean wave generated by an earthquake, propagates along the open ocean at 700 km/hr and has a wavelength of 750 km

Colt1911 [192]

Answer:

C) 0.00026 Hz

Explanation:

In any wave, there exists a fixed relationship between the speed v, the frequency f and the wavelength λ, as follows:

$v = \lambda * f (1)$

Replacing by the givens in (1), and solving for f, we get:

$f = \frac{v}{\lambda} = \frac{700km/hr}{750 km} = 0.93 1/hr (2)$

Converting the units to Hz (1/sec), we get:

$f = 0.93 \frac{1}{hr} *\frac{1 hr}{3600sec} = 2.6e-4 = 0.00026 Hz (2)$

The answer C. is the right one.
