Explanation:

u=40

v=?

h=?

v²-u²=2gs

0²-40²=2×10×s

160=20s

s=160/20

=80m/s

total distance= upward distance ×downward distance

=80+80

=160m

total displacement=0 because u and v is the same.

Answer:

The maximum height is 80 m and the total distance covered by the stone is 160 m and the displacement is zero.

Explanation:

Final velocity v = 0

Initial velocity u = 40m/s

We know that,

Using equation of motion

v^{2} =u^{2} +2gh

0-40^{2} =2 × 10 × h

The maximum height is:

h=80 m

The  stone will reach at the top and will come down

Therefore, the total distance will be:

s=h_{1} +h_{2}

s=80m-80m=160m

The net displacement is:

D=h_{1} -h_{2}

D=80m-80m=0

Hence, The maximum height is 80 m and the total distance covered by the stone is 160 m and the displacement is zero.

Why do hurricanes rotate counterclockwise in the northern hemisphere
Genrish500 [490]

Answer:

A hurricane's spin and the spin's direction is determined by a super-powerful phenomenon called the Coriolis effect. It causes the path of everything from particles in the air to currents in the ocean so they curve as they travel across and over Earth's surfaces.

Calculate the magnitude of the electric field at the location of given that the square is 6.05 cm on a side.
Serggg [28]

The term “electric field” refers to the physical field that surrounds electrically charged particles and acts to either attract or repel all other charged particles in the field (also known as an E-field).

It can also refer to the physical field surrounding a system of charged particles. Electric fields are composed of electric charges and time-varying electric currents.

Both electric and magnetic fields are manifestations of the electromagnetic field, one of the four fundamental interactions (sometimes known as forces) of nature.

Electrical technology makes use of electric fields, which are significant in many branches of physics.

For instance, in atomic physics and chemistry, the electric field acts as an attractive force to hold atoms’ atomic nuclei and electrons together. It is also the force that causes atoms to chemically link together to form molecules.
