Answer:
Explanation:
Yes I agree with the statement .
When a person who is perfectly insulated from the earth , touches a Van de Graaff , his body acquires charge . when the hair acquires it, it stands out due to mutual repulsion . It is to be noted here that at pointed areas on a surface , there is larger accumulation of charge. Accumulation of charge is greater at hair tops .
It is also a general observation that when a bird sits on high tension wire , his feather stands out due to the same reason.
Answer:
v₂ = 22.5 m/s
Explanation:
Given that
For puck 1
m₁= 1 kg
u₁= 30 m/s
For puck 2
m₂= 1 kg
u₂= 0 m/s
After collision
Puck 1 have velocity v₁=7.5 m/s
Take puck 2 will have velocity v₂
From linear momentum conservation
P₁=P₂
m₁ u₁+m₂ u₂=m₁ v₁+m₂ v₂
1 x 30 + 1 x 0 = 1 x 7.5 + 1 x v₂
30 - 7.5 =v₂
v₂ = 22.5 m/s
The speed of Matt is 10 mph.
Doug runs 2 miles an hour faster than Matt, so let Matt’s speed equal x miles per hour. Then Doug’s speed equals x + 2 miles per hour. Each lap is one-quarter of a mile, so Doug runs 1.5 miles in the time it takes Matt to run 1.25 miles.
Rate of Matt is x
Rate of Dough is (x + 2)
Time taken by Matt is 1.25/x
Time taken by Dough is 1.25/(x + 2)
Distance covered by Matt is 1.25
Distance covered by Dough is 1.5
Dough and Matt took the same amount of time from the time Doug started, so make an equation by setting the two times in the chart equal to each other, and then solve for x:
= 
1.5x = 1.25(x + 2)
1.5x = 1.25x + 2.5
0.25x = 2.5
x = 10
So Matt ran at 10 miles per hour.

Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
