Solve the given parallel circuit by computing the desired quantities.

alexandr402 [8]

Answer:

1.92 m/s

Explanation:

Velocity is defined as the distance moved per unit time with consideration of the direction. The direction aspect differentiates speed from velocity since for speed, we don't need to consider the direction.

$v=\frac {d}{t}$

Distance moved for circular path is equal to its circumference and the circumference is given by $2\pi r$ where r is the radius and substituting $2\pi r$ for d then

$v=\frac {2\pi r}{t}$

Substituting 5.5 m for r and 18 s for t then

$v=\frac {2\pi \times 5.5}{18}=1.919862177 m/s\approx 1.92 m/s$

To the nearest hundredth, the velocity is 1.92 m/s

Why is the world round

zlopas [31]

The gravity pulls itself into a sphere also known as hydrostatic equilibrium. This gives the planet a sphere-like shape.

Hope that helps. -UF aka Nadia

The velocity of the transverse waves produced by an earthquake is 4.05 km/s, while that of the longitudinal waves is 7.695 km/s.

lora16 [44]

Answer:

x = 600 Km

Explanation:

given,

speed of transverse wave = 4.05 Km/s

speed of longitudinal wave = 7.695 Km/s

difference of the time of arrival of wave = 69.9 s

now,

t₂ - t₁ = 69.9 s

let x be the distance

$\dfrac{x}{4.05} - \dfrac{x}{7.695} = 69.9$

$x = \dfrac{69.9\times 4.05 \times 7.695}{7.695-4.05}$

x = 597.645 Km

x = 600 Km

distance of recorder from the site is 600 Km approximately.

Define habitat preservation and give at least two examples.

lisov135 [29]

Habitat preservation is when people get together or just one person helps to stop the end of a living space for animals such as the monterey aquarium the help sea life by doing research to see why animals are dying and do what they can to stop it. another one if nation parks or forests you are not allowed to harm them in any way they are protected by laws(the government)
