Evaluate the numerical value of the vertical velocity of the car at time t=0. 25s using the expression from part d, where y0=0.
Alex73 [517]

The vertical velocity of the car at the given position and time is 4.905 m/s.

The given parameters:

  • Initial angular velocity, \omega_0 = 6.3 rad/s
  • Time of motion, t = 0.25 s
  • Vertical displacement, y = 0.75 m
  • Angular acceleration, \alpha  = 0.95 \ rad/s^2

<h3>What is vertical velocity?</h3>
  • This is the linear velocity of an object in a vertical direction.

The angular velocity of an object in a circular motion is given as;

\omega_f = \omega _0 + \alpha t\\\\\omega _f = 6.3 \ +\  0.95 \times 0.25 \\\\\omega _f = 6.54 \ rad/s

The vertical velocity of the car at the given position and time is calculated as follows;

v = \omega r\\\\v = \omega_f y\\\\v = (6.54 \ rad/s)\times (0.75\ m)\\\\v = 4.905 \ m/s

Thus, the vertical velocity of the car at the given position and time is 4.905 m/s.

Wild parrots live in warm climates. Few young parrots would survive an exceptionally cold winter in these regions. If this cold
melisa1 [442]

The statements that best describes how the parrot species will respond is that they will migrate to higher latitudes to preserve their population.

<h3>How will the parrot adapt?</h3>

Despite that organism adapt with conditions, it will be difficult for the parrot to withstand continuously the cold winter in these regions for a year.

Hence, the parrot species will respond by migrating to higher latitudes to preserve their population.

Therefore, the Option B is correct.

Missing options <em>"A)The surviving parrots will die during this winter or the next winter., B)The parrots will migrate to higher latitudes to preserve their population., C)The surviving parrots will produce offspring that have larger feathers to cover the body., D)The parrot population will, over generations, produce offspring that are better able to tolerate cold weather."</em>

  • Homogeneity of product.
  • No existence of buyers or sellers.
  • Access to information.
  • No charge fr yranascation cost.
  • No barries to entry or exit.

Hence, because of the difference imposed by the market and political decisions, the government borrowing cannot be reduced neither will there be an increase in the tax budget nor will the government budget hide the rate of private investment.
