Answer:-

8.94 seconds

Explanation:-

S=400m,.

a= 10 m/s^2.

u=0

t=?

s =ut +1/2at^2 400= 0*t +1/2*10* t^2 t= √400*2/10 t= √80 t= 8.94s

Although the evidence is weak, there has been concern in recent years over possible health effects from the magnetic fields gene
Natasha2012 [34]

Answer:

A. B = 6.36 * 10^{-10} T

B. P ≈ 0

Explanation:

In order to calculate the magnetic field strength we have to use the magnetic field strength of a straight wire.

B = \frac{mi* I}{2\pi *d} (eq. I)

B = magnetic field strength at distance d

I = current (A)

mi = represented by the greek letter μ, represents the permeability of the free space, which is: 4 × π 10^(-7) T m/A

d = distance from the wire

By replacing the values in eq I, we have the following:

B = \frac{4\pi  10^{-7} T  m  A^{-1}  200 A}{2\pi *20 m}\\\\B = 6.36 * 10^{-10}  T\\ (eq II)

The earth magnetic field in the surface variates from 25 to 65 microteslas. Thus:

P = Percentage from the wires/percentage of the earth

P = \frac{6.36 * 10^{-10}T}{65* 10^{-3} T}\\ ∵ B ∴

P ≈ 0

7) Germanium, element 32 on the Periodic Table, is shown here. If a proton is added to the nucleus of germanium, what outcome(s)
cestrela7 [59]

Addition of a proton to germanium  will convert it to arsenic (element 33) having different properties.

The atomic number of an atom is the number of protons in the nucleus of the atom. The atomic number serves as the identity of an atom. If the atomic number is changed by adding or removing protons, the identity of that atom changes.

Hence, when a proton is added to germanium, the  atom would become arsenic (element 33) and have different properties.

The top of a tower much like the leaning bell tower at Pisa, Italy, moves toward the south at an average rate of 1.4 mm/y. The t
Gemiola [76]

Answer:

\omega=7.16*10^{-13}\frac{rad}{s}

Explanation:

The angular speed is given by:

\omega=\frac{v}{r}

Here v is the linear speed and r is the radius of the circular motion. The height of the tower is equal to the radius of the circular motion of the top of the tower, since is rotating about its base. We need to convert the given linear speed to \frac{m}{s}:

1.4\frac{mm}{y}*\frac{10^{-3}m}{1mm}*\frac{1y}{3.154*10^7s}=4.44*10^{-11}\frac{m}{s}

Now, we calculate the angular speed:

\omega=\frac{4.44*10^{-11}\frac{m}{s}}{62m}\\\omega=7.16*10^{-13}\frac{rad}{s}
