How long does it take Rick to cover the distance D?
Here we have the running speed of Rick =
The walking speed of Rick =
Therefore, since Rick walks half of the distance and runs the other half, we have
Distance for walking = D/2 and distance for running = D/2
Rick"s time in running is
Total time is given by
The inter-base.net is 250 g
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
volume = 250 mL
density = 1 g/mL
So we have
mass = 250 × 1
We have the final inter-base.net as
Hope this helps you
This happens because the.....particles are most likely to escape from the liquid, causing the temperature of the liquid to.....
Explanation: If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer.

The motion of a piston of a car engine approximates simple harmonic motion. Given that the stroke (twice the amplitude) is 0.100
y = - 0.050 sin (131.59t )
In this exercise we are told to approximate the movement of a piston to the simple harmonic movement
y = A cos (wt + Ф)
in this case they indicate that the stroke (C) of the piston is twice the amplitude
C = 2A
A = C / 2
angular velocity is related to frequency
w = 2π f
To find the phase (fi) we will use the initial conditions, the piston starts at the midpoint of the stroke, if we create a reference system where the origin is at this point
