Magnitude is the absolute max velocity a person can reach while falling ⇒ answer D

Explanation:

Terminal velocity is the maximum velocity attainable by an object

as it falls

  • An object dropped from rest will increase its speed until it reaches terminal velocity
  • terminal velocity is the point at which the velocity is no longer getting greater
  • At terminal velocity air resistance force and weight are equal so speed is constant

Example:

A falling person at low altitude will reach terminal velocity after about 12 seconds, falling some 450 m in that time. He will then maintain this speed without falling any faster

Absolute value means the non-negative value

That means the magnitude of the value without its direction

The answer of the question is:

Magnitude is the absolute max velocity a person can reach while falling

What is the control group used for
LUCKY_DIMON [66]

Answer:

What is a Control Group? The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It's a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment

A proton of mass 1.67×10-27 kg is being accelerated along a straight line at 7.01×1015 m/s2 in an accelerator. If the proton has
Masja [62]

Answer:

v_f=7*10^7\frac{m}{s}

Explanation:

The proton is under a linear motion with constant acceleration. So, we use the kinemtic equations to calculate its final speed. We know its acceleration, its initial speed and its traveled distance. Thus, we use the following equation:

v_f^2=v_0^2+2ax\\v_f=\sqrt{v_0^2+2ax}\\v_f=\sqrt{(6.63*10^7\frac{m}{s})^2+2(7.01*10^{15}\frac{m}{s^2})(3.63*10^{-2}m)}\\v_f=7*10^7\frac{m}{s}

Laminar flow, where water moves in approximately straight-line paths, characterizes ________.
densk [106]

Answer:

b. slow-moving streams.

Explanation:

In Fluid Mechanics, the Reynolds numbers indicates the existence of turbulence in fluid streams. Low Reynolds numbers are related with laminar flow. The Reynolds formula is:

Re = \frac{\rho_{water} \cdot L_{c}}{\mu_{water}} \cdot v

The Reynolds number is directly proportional to fluid speed. Hence, slow-moving streams are a sound example of laminar flow. The correct answer is B.
