<span>The chemical properties of ANY atom are found in how they react with other elements.
A. An element's symbol - Nothing to do with reactions
B. The average atomic mass -The mass doesn't react
C. The number of electrons that occupy the outer shell - the only part of the electrons that move, SO they are involved in the reactions (answer)
D. The total number of electrons - The inner electrons cannot move from the atom unless there is ALOT of energy given to them, so these cannot react and would not contribute to the chemical properties.</span>
Answer:
So the weight of the body is 700N
Explanation:
mass of the object=70kg
force of gravity=10N/kg
weight of the object=w-?
as we know that
weight=mass × force of gravity
weight=70kg × 10N/kg
WEIGHT OF THE BODY=700N
I HOPE IT WILL HELP YOU
GOOD LUCK FOR THE ASSIGNMENT
sorry accidentally posted here.
use Newton's gravitational law and 2nd law .....
Answer:
<h2>The water will move faster</h2>
Explanation:
This happens as part of the consequences of the continuity of an incompressible fluid, of which water is an example.
so as the water emerges from the wider section the flow velocity increases and vice versa.
Hence the flow velocity in indirectly proportional to the area
The continuity equation is given below for our analysis
-------------------1
where
A1= the area of the wider section of the tank
V1= the flow velocity from the wider section
A2= the area of the hole at the bottom
V2= velocity of flow at the bottom.
