Yes. Petroleum, or crude oil, is a fossil fuel and is used to create items such as bubble gum, plastic, etc.
Answer:
1.5F
Explanation:
Using
E= F/q
Where F= force
E= electric field
q=charge
F= Eq
So if qis tripled and E is halved we have
F= (E/2)3q
F= 1.5Eq=>> 1.5F
The maximum height of the object when thrown at the speed of 20 m/s is 20 m.
What is speed?
Speed is the magnitude of the rate of change of the position of any object with time which is a scalar quantity. It is the ratio of speed by time with the unit m/s or cm/s.
The height this object can travel with initial speed of 20 m/s can be calculated as,
<u>v^2 = u^2 + 2as</u>
where v is the final velocity, u is the initial velocity a is the acceleration due to gravity s is height.
0 = 20^2 + 2 (-10) s
s = 400 / 20 = 20 m
Therefore, the maximum height the object can travel with initial speed of 20 m/s is 20m.
