Outside controlled airspace, the minimum flight visibility requirement for vfr flight above 1,200 feet agl and below 10,000 feet
nalin [4]
The least possible flight visibility prerequisite for VFR flight above 1200 feet AFL and below 10000 feet MSL for the duration of daylight hours is 1 mile in the external controlled airspace. In aeronautics, visual meteorological conditions or as called as VMC is an aviation flight group in which visual flight rules or VFR is allowed that is in circumstance in which pilot have adequate visibility to fly the aircraft sustaining visual leave-taking from terrain and other aircraft. They are the contradictory of instrument meteorological conditions. The border standards among instrument meteorological conditions and visual meteorological circumstances are recognized as the visual meteorological conditions minima and are well-defined by visibility, cloud ceilings for take offs and landing and cloud allowances.

A girl drops a pebble from a high cliff into a lake far below. She sees the splash of the pebble hitting the water 2.00s later.
Natali5045456 [20]

Answer:

19.62 ms

Explanation:

t = Time taken = 2 s

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s² (downward direction is taken as positive)

Equation of motion

v=u+at\\\Rightarrow v=0+9.81\times 2\\\Rightarrow v=19.62\ m/s

The speed of the pebble when it hit the water is 19.62 ms

A 240 g toy car is placed on a narrow 60-cm-diameter track with wheel grooves that keep the car going in a circle. The 1.0 kg tr
lesya [120]

Answer:

The track's angular velocity is W2 = 4.15 in rpm

Explanation:

Momentum angular can be find

I = m*r^2

P = I*W

So to use the conservation

P1 + P2 = 0

I1*W1 + I2*W2 = 0

Solve to w2 to find the angular velocity

0.240kg*0.30m^2*0.79m/s=-1kg*0.30m^2*W2

W2 = 0.435 rad/s

W2 = 4.15 rpm
