Answer:
1.63 s
Explanation:
The skier lands on the sloped section when the direction of its velocity is exactly identical to that of the slope, so at
below the horizontal.
This occurs when the magnitude of the vertical velocity is equal to the horizontal velocity (in fact,
, and since
and so
.
We already know the horizontal velocity of the skier:

And this is constant during the entire motion.
The vertical velocity instead is given by

where
is the initial vertical velocity (zero since the skier flies off horizontally)
g = 9.8 m/s^2
t is the time
Here we have chosen the downward direction as positive direction.
Substituting
, we find the time:

Answer:
Cumulonimbus
Hail development. Hail is a type of strong precipitation, which is shaped in rainstorms mists (Cumulonimbus). Tempests mists comprises of beads of fluid water (at temperatures lower than 0°с, the beads can be in a thermodynamically instable supercooled condition) and ice gems
Explanation:
The equation that relates the voltages and the number of turns in a transformer is

where

is the voltage in the secondary coil,

is the voltage in the primary coil, and

and

are the number of turns on the secondary and primary coils.
Using the numbers, we find the ratio between the number of turns:
the answer is A it is so easy question
