Which one of these situations would have higher density water? Water with a lower salt content Water at the equator Water near where a river enters the ocean Lower temperature water​

Explanation:

water near where a river enters the ocean is having a higher density.

coz, ocean water has salt which increases water's density

the correct answer is lower temperature water do not listen to the guy who said his answer is incorrect i go 100% so the correct answer IS LOWER TEMPERTURE WATER

Explanation:

I GOT 100% THIS IDIOT ABOVE ME IS WRONG

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

the answer would be c
