Answer:
192N
Explanation:
Since we were give mass and acceleration, therefore magnitude of force will be
F=ma
8×24=192
A.draw in the forces .Use the scale 1cm =10n of force
The electron near the Earth's equator doesn't deflect if it's velocity is directed downwards.
Assume that north is directed along upwards, south is directed along downwards, east is directed along rightwards, and west is directed along leftwards.
The magnetic force on the charge q, moving with velocity v in the magnetic field B is given by
F=q(→v×→B)=qvBsinθ ..(1)
Here,
θ is the angle between the magnetic field and velocity.
Inside the Earth, the Earth's magnetic field is along northward (upwards), and the velocity is given to be along southwards (downwards) making an angle of 180°. In equation (1) sin180°=0. So, no magnetic force acts on the electron
Therefore,
The electron didn't deflect if it is directed downwards.

A compound is two or more elements combinded together.
A element is a pure substance.
it looks like all of them are compounds except the carbon dixode, My teacher would accept that as a anwser idk bout urs thoughs.
