Answer:
Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
Explanation:
Volcanoes are found around tectonic plates because the convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other, plates converge and the plates move together, also known as ridge push, therefore mountains and volcanoes are formed

Explanation:
The box fall with acceleration 10m/s2 due to gravity
velocity/ 6.1 = 180
velocity = 1098 m/s
the answer is A.
Answer:
A. negatively charged are deposited on the belt, which deposits positive charges on the metal ball.
Explanation:
Negatively charged ions are injected at one end of thebelt towards the high potntial terminal, where they are acclerated by attractive forces towards the terminal. When the particles reach the terminal, they are stripped of some electrons to make them positively charged.
Answer:
18.15m/s
Explanation:
Recall for coefficient of kinetic friction
F=UR
We're F=m*a= U*m*g
Hence a= U*g
We're a= acceleration,U coefficient of kinetic friction,g= acceleration due to gravity hence a=24*0.7=6.867m/s^2 because break was applied it is a negative acceleration hence a= -6.867m/s^2
But V=v+at at final velocity V=0
Hence 6.867*T=v T=v/6.867
But average speed =v/2
Using Newton law of motion
S=(V+v)T/2
Substitute for S,V,v and T
24=(v/2)v/6.867
v^2=329.6
V=18.15m/s
