Explanation:
It is given that,
Speed of the plane, v = 110 m/s
Radius of circle, r = 2850 m
(1) Let t is the time taken by a plane. Speed of the plane is given by :
t = 162.79 s
(2) Mass of a driver, m = 50 kg
Height, h = 6 m
As the driver reaches ground, its potential energy point to zero. So, the change in potential energy is given by :
So, the change in potential energy is 2940 joules.
Let v is the speed. As the driver reaches water surface, its potential energy is converted to kinetic energy as :
v = 10.84 m/s
So, the speed of the reactors the water is 10.84 m/s. Hence, this is the required solution.

Sound waves travels slowest in gases.
Hope's apparatus is a glass cylinder encircled with a trough half-way up to contain a freezing mixture. Holes in the cylinder at the top and the bottom allow thermometers to be inserted into the water to sample its temperature.

Answer:
F = qvB sinθ
(Hope this helps! Btw, I am the first to answer. Brainliest pls! :D)
Maybe for the first the hand because there are so many joints that do so many movements and functions.
For the second, the tongue because there are so many taste buds that need to sense and taste and move.
I hope that helps, that's what I remember from elementary school. XD
