You are watching: How long does it take rick to cover the distance d?

**Question:**

How long does it take Rick come cover the street D?

**inter-base.net:**

The time,

, rick takes come cover the distance D is;**Explanation:**

Here we have the running rate of stack =

and alsoThe walking speed of rick =

Therefore, due to the fact that Rick walks half of the distance and also runs the other half, us have

Where

Distance because that walking = D/2 and distance for to run = D/2

Rick"s time in running is

and also time in walking is

Total time is offered by

**inter-base.net:**

## The inter-base.net is 250 g

**Explanation:**

The fixed of a substance when given the density and volume can be found by utilizing the formula

### mass = density × volume

From the question

volume = 250 mL

density = 1 g/mL

So us have

mass = 250 × 1

We have actually the final inter-base.net as

### 250 g

Hope this helps you

This happens because the.....particles are most likely to escape native the liquid, leading to the temperature that the liquid to.....

inter-base.net:Boiling

Explanation: If a fluid is boil the particles room given much more energy and also move faster and faster broadening the liquid. The most energetic particles at the surface ar escape indigenous the surface of the liquid as a vapour as it gets warmer.

The motion of a piston that a automobile engine approximates straightforward harmonic motion. Provided that the punch (twice the amplitude) is 0.100

**inter-base.net:**

y = - 0.050 sin (131.59t )

**Explanation:**

In this practice we room told to almost right the motion of a piston come the straightforward harmonic movement

y = A cos (wt + Ф)

in this situation they indicate that the hit (C) the the piston is double the amplitude

C = 2A

A = C / 2

angular velocity is concerned frequency

w = 2π f

let"s substitute

y =

cos (2π f t +Ф)To uncover the step (fi) we will usage the early stage conditions, the piston starts in ~ the midpoint of the stroke, if we develop a reference device where the origin is in ~ this point
