Answer:
v = distance/time = 60m/20s = 3 m/s
The correct answer is the first option. The piece of evidence would suggest an unknown substance is an ionic compound is that <span>it conducts electricity when dissolved in water.</span><span> A</span><span>n ionic compound dissociates
into ions when in aqueous solution. These ions move freely in the solution and
can allow the flow of electricity into the solution.</span>
Answer:
distance decreases and force increases
Explanation:
- Simple machine means less power
- Hence it will require more force.
- Hence distance will decrease with respect to force and force will decrease
