Answer:

tortoise distance w.r.t sloth is 28.08 m further

Explanation:

given data

average speed v1 = 0.037 m/s

walking speed v2 = 0.076 m/s

time t = 12 min = 720 seconds

to find out

how much tortoise have gone wrt sloth

solution

we find here first tortoise walk that is

distance d1 = v2 × t

distance d1 =  0.076  × 720

distance d1 = 54.72 m

and sloth walk distance

distance d2 = v1 × t

distance d2 = 0.037 × 720

distance d2 = 26.64 m

and so

tortoise distance w.r.t sloth = d1 - d2

tortoise distance w.r.t sloth = 54.72 - 26.64 = 28.08

tortoise distance w.r.t sloth is 28.08 m further

A long solenoid has 103 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.60 cm perp
Aneli [31]

Answer:

0.23348 A

Explanation:

B = Magnetic field

v = Velocity of electron = 1.38\times 10^7\ m/s

q = Charge of electron = 1.6\times 10^{-19}\ C

\mu_0 = Vacuum permeability = 4\pi \times 10^{-7}\ H/m

r = Radius of circle = 0.026 m

N = Number of turns = 103 turns/cm = 103\times 100\ turns/m

I = Current

The magnetic and centripetal force will be balanced

Bqv=m\frac{v^2}{r}\\\Rightarrow B=\frac{mv}{qr}

The magnetic field in solenoid is given by

B=N\mu_0 I\\\Rightarrow I=\frac{B}{N\mu_0}

From the first equation

I=\frac{\frac{mv}{qr}}{N\mu_0}\\\Rightarrow I=\frac{mv}{N\mu_0qr}\\\Rightarrow I=\frac{9.11\times 10^{-31}\times 1.38\times 10^7}{103\times 100\times 4\pi \times 10^{-7}\times 1.6\times 10^{-19}\times 0.026}\\\Rightarrow I=0.23348\ A

The current in the solenoid is 0.23348 A

Why is it sometimes difficult for scientists to identify a a fold or fault?
Sauron [17]

Folds and faults are difficult to identify because they occur in the interior of rocks and also due to the dense nature of the materials.

<h3>What are faults and folds?</h3>

Faults are lines of weakness are present in materials dues to uneven positioning of the particles of the material.

Folds occurs when infolds occur in materials.

Faults and folds usually occur in rocks.

Folds and faults are difficult to identify because they occur internally and also due to the dense nature of the materials.
