Anyone know how to unclog a kitchen sink. We tried a plunger, products and nothing worked!!!

1 cup white vinegar and 1/2 cup baking soda. Pour both down the drain wait for 15 mins then dump steaming hot water down in the drain for alittle bit and then it should loosen whatever is stuck. Works for us.

onto a large boat, and mark the water level that the boat sinks to. then, take the elephant out and put a bunch of marked weights onto the boat until it reaches the same water level. add up the masses of the weights to get the weight of the elephant.

i think the answer is c. she can't feel happy because things are moving too quickly.
