Physics

Scilla [17]1 year ago

The distance from the surface where the is measured as the hydrodynamic boundary layer thickness. The local exterior velocity is the same as the speed.

<h3>What is velocity?</h3>
  • Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound).
  • In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.
  • A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined.
  • Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or ms1) in the SI (metric system).
<h3>What is speed?</h3>
  • The speed of an object, also known as v in kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time, making it a scalar quantity.
  • The instantaneous speed is the upper limit of the average speed as the duration of the time interval gets closer to zero.
  • The average speed of an object in a period of time is the distance traveled by the object divided by the duration of the interval.
  • Velocity and speed are not the same thing.

As for me, there are two suitable answers for the question represented above and here is a short explanation why I consider these two to be correct :

The air movements toward the equator are called trade winds, which are warm, steady breezes that blowalmost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north. Answer trade wind

Human-Powered Flight Human-powered aircraft require a pilot to pedal, as in a bicycle, and produce a sustained power output of a
alukav5142 [94]

Answer:

# of Snickers bars 2

Explanation:

Power output= 0.30 HP

=0.3*746

= 0.30 HP (746 W=1.00 HP)

= 224 W

time required 2 h 49 m = 10140 seconds

Since power is work divided by time, then work is:

Work done by the jet = P*t

= 224 *(10140)

= 2.3 MJ (2.3 x 10^{6} J)

Converting MJ to Cal

2.3 MJ=549 Cal

# of Snickers bars = 549 Cal / 280 Cal

= 2.0 bars (rounded from 1.96)

Define neuron and nerve<br>cell​
san4es73 [151]

Answer: Hi!

A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.

Hope this helps!
