What is a vector A quantity that has both mass and speed.

A quantity that has both size and direction. Help asap

Explanation:

As I think Option 2 is the correct one.

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.

well this my answer.

releases oxygen is a light-independent reaction and so is (fixes carbon dioxide. light-dependent reaction takes place in the stroma and lights dependent reaction take place in the grana, light-dependent reactions produce atp. and last but not least, light dependent reactions produces glucose.

hope it : )
