A stone is dropped into water from a bridge 52 m above the water's
dusya [7]

Answer:

Its final velocity and how much time it takes to reach the water

Explanation:

The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:

v^2-u^2=2as

where

v is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2 is the acceleration of gravity

s = 52 m is the distance covered during the fall

Solving for v,

v=\sqrt{u^2+2as}=\sqrt{0^2+2(9.8)(52)}=31.9 m/s

We can also find how much time it takes to reach the water, using the equation

v=u+at

where

v = 31.9 m/s is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2

t is the time

And solving for t,

t=\frac{v-u}{a}=\frac{31.9-0}{9.8}=3.26 s

7nadin3 [17]

Answer:

The poles of an electromagnet can even be reversed by reversing the flow of electricity. If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops. ... All of their little magnetic fields add together, creating a stronger magnetic field.

Mia plays soccer for her high school team. generally, they start practice by stretching. what kind of stretching should they do
Keith_Richards [23]

Mia plays soccer for her high school team. generally, they start practicing by stretching. The kind of stretching should they do before they are warmed up is Dynamic Stretching

Dynamic Stretching consists of techniques that involve active stretching to reduce force and its negative effects. Muscles are stimulated and made ready for usage during exercise by dynamic stretching.

Dynamic stretching not only stretches the muscles and tissues but also activates and warms up the muscles to get them ready for action.

We require our muscles' flexibility to maintain the range of motion in our joints, so stretching keeps them strong, flexible, and healthy. The muscles shorten and tighten without it. The muscles are then weak and unable to fully expand when you want them to work.
