Answer:
It will float
Explanation:
its density is lower than density of water
Its density is 670 / 782 = 0.856 kg/m³
A major obstacle to developing a good human relations skill is that : few person have a common interest a communication between two people will be a lot easier if they have common interest because a person tend to like other person that are similar to him (whether it's race, background , or common interest).
Winter and Summer happen every year, pretty much on schedule.
When they happen, the 'weather' changes, but the 'climate' doesn't.
If you live in the right place, then you might get several blizzards every
Winter. They're changes in the 'weather' but not in the 'climate'.
If the temperature where you live stays well below zero for a hundred
years, then you might be entering an ice age.
Or let's say your town has had blizzards every Winter for the past 20 years
but it never had one for 100 years before that.
Either of these would be a climatic change.
Answer:
E = 1000 x
Explanation:
The electric potential and the electric field are related by the formula
dV = - E . dx
Bold represents vectors.
The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product
E = dV /dx
Let's make the derivative
E = - 2ax
Let's replace the values
E = -2 (-500) x
E = 1000 x
