Answer:

Into the page

Explanation:

According to Fleming's hand rule, the middle finger represent the direction of the current, the forefinger represents that of the magnetic field and the thumb gives the direction of the force. when you hold out your left hand with the forefinger, middle finger and thumb at the right angle to one another as the thumb points upward the middle finger will point rightward and the forefinger will point in the direction into the paper.

Exoplanets (planets outside our solar system) are an active area of modern research. Suppose astronomers find such a planet that
Leno4ka [110]

Answer:

8.829 m/s²

Explanation:

M = Mass of Earth

m = Mass of Exoplanet

g_e = Acceleration due to gravity on Earth = 9.81 m/s²

g = Acceleration due to gravity on Exoplanet

m=M-0.1M\\\Rightarrow m=0.9M

g_e=G\frac{M}{r^2}

g=G\frac{0.9M}{r^2}

Dividing the equations we get

\frac{g}{g_e}=\frac{G\frac{0.9M}{r^2}}{G\frac{M}{r^2}}\\\Rightarrow \frac{g}{g_e}=0.9\\\Rightarrow g=0.9g_e\\\Rightarrow g=0.9\times 9.81\\\Rightarrow g=8.829\ m/s^2

Acceleration due to gravity on the surface of the Exoplanet is 8.829 m/s²

Strength of the magnetic field: C) 20 T

Explanation:

When a conductive wire moves in a region with magnetic field, an electromotive force is induced in the wire due to the phenomenon of electromagnetic induction.

If the wire moves perpendicular to the field, the magnitude of the induced emf in the wire is given by

\epsilon=BLv

where

B is the strength of the magnetic field

L is the length of the wire

v is the speed of the wire

For the wire in this problem, we have:

\epsilon=12 V is the emf induced in the wire

v = 3.0 m/s is the speed of the wire

L = 0.20 m is its length

Solving for B, we find the strength of the magnetic field:

B=\frac{\epsilon}{Lv}=\frac{12}{(0.20)(3.0)}=20 T
