A cart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/s2. If the cart has a beginning speed of 2.0 m/s, wh

Digiron [165]

Answer:

22m/s

Explanation:

Given parameters:

Time = 5s

Acceleration = 4m/s²

Initial velocity = 2m/s

Unknown

Final speed = ?

Solution:

To solve this problem, we use the expression below;

v = u + at

v is the final speed

u is the initial speed

a is the acceleration

t is the time taken

So, insert the parameters and solve;

v = 2 + 4 x 5 = 22m/s

Which of the following equations represents Photosynthesis? 16CO2 + 6H2O -----> C6H12O6 + 6O22C6H12O6 + 6O2 -----> CO2 + 6

lidiya [134]

Answer:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Explanation:

Photosynthesis is the chemical process carried out by plants for the conversion of inorganic matter (carbon dioxide and water) into organic matter (glucose) with the release of oxygen, using light (sun energy).

So the chemical process may be represented by:

Word equation:

carbon dioxide + water + sun energy → glucose + oxygen

Skeleton equation:

CO₂ + H₂O + sun energy → C₆H₁₂O₆ + O₂

Balanced chemical equation:

6CO₂ + 6H₂O + sun energy → C₆H₁₂O₆ + 6O₂

Supressing the energy to show only the chemical compounds:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
