This is an example of the phi phenomenon. This is an optical illusion that occurs when a series of still images, in this case the flashing lights, are viewed in quick succession. This given the illusion of a continuous movement rather than discrete still images.

A hailstone, 120 m above the
Stells [14]

The hailstone will hit the earth in 4.04 seconds.

we move 9.8 meters per second faster thanks to gravity. we   start to fall after one second at 9.8 m/s. we start falling at 19.6 m/s after two seconds, and so forth.

From the query, the following information may be deduced:

Height (H) = 120 m

Gravitational acceleration (g)=9.8 m/s2.

Time (t)=?

It is possible to determine the hailstone's impact time as:

h=1/2 gt²

120= 1/2 x 9.8 x t²

120x2/9.8=t²

t²=24.48

t=4.94 s

therefore, the calculated time taken is 4.94 s.

❍The period of oscillation of the single pendulum depends on its length and acceleration for the period of oscillation. Derive t
kirill115 [55]

  • <em>each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.</em>

Find initial velocity and time in air​
kkurt [141]

Answer:

The answer to your question is: v = 121.46 m/s

Explanation:

Data

h = 30 m

vo = ?

dx = 300 m

Formula

t = \sqrt{\frac{2h}{g}}

speed = distance / time

Process

t = \sqrt{\frac{2(30)}{9.81}} \\

t= 2.47 s

speed = 300 / 2.47

speed = v = 121.46 m/s

A thin, rectangular sheet of metal has mass M and sides of length a and b. Find the moment of inertia of this sheet about an axi
Lubov Fominskaja [6]

Answer:

The moment of inertia is I=\frac{M}{12} a^{2}

Explanation:

The moment of inertia is equal:

I=\int\limits^a_b {r^{2} } \, dm

If r is -\frac{a}{2}

and dm=\frac{M}{a} dr

I=\int\limits^a_b {r^{2}\frac{M}{a}  } \, dr\\a=\frac{a}{2} \\b=-\frac{a}{2}

I=\frac{M}{a} \int\limits^a_b {r^{2}  } \, dr\\\\I=\frac{M}{a} (\frac{M}{3} )_{b}^{a}\\  I=\frac{M}{3a} (\frac{a^{3} }{8} +\frac{a^{3} }{8} )\\I=\frac{M}{12} a^{2}

A pilot is flying a commercial plane from New York City to Orlando. If the pilot fails to take the Coriolis Effect into account,
grin007 [14]

Answer:

<u>B. East of NYC</u>

Explanation:

We can make this conclusion because for one reason New York City is the Northern Hemisphere, and according to the Coriolis effect <em>when objects in the Northern Hemisphere travel long distances above the ground, </em><em>they will be deflected to the right </em>as a result of earth's rotation.

Hence, going by the map of New York on the Northern Hemisphere, <em>when the (object) flight is deflected to the right, for someone in NYC it will indicate a </em><em>shift to the east of NYC</em><em> </em>since the pilot failed to take the Coriolis Effect into account.
