Answer : the first product for carbon dioxide is C2CNT. Product: Carbon nanotubes, carbon fiber. the second product for hydrogen is fertilizer. a product for oxygen is water. the reactants of carbon dioxide is carbon dioxide (CO2), water (H2O), and usable energy. the reactants of hydrogen is Both hydrogen and oxygen gases exist as diatomic (“two-atom”) molecules. the reactants of oxygen is oxygen gas and the 2 in front of the water vapor are called the reaction coefficients.

Answer:
The football must be launched whit an angle of 20,487 degrees to reach a maximum height of 10 meters.
Explanation:
To solve this problem we use the parabolic motion equations:
We define:
: total initial speed =
:initial speed component in vertical direction (y)
=
: vertical speed at any point on the parabolic path
g= acceleration of gravity= 9,8
= angle that forms the total initial velocity with the ground
Equation of the speed of the football in the vertical direction :
Equation (1)
We replace, in the equation (1):
Equation(2)
Angle calculation
The speed of the football in the vertical direction gradually decreases until its value is zero when it reaches the maximum height.
We replace , in the equation (2)
°
Answer:The football must be launched whit an angle of 20,487 degrees to reach a maximum height of 10 meters.
PITCH
please mark brainliest!!!
Av Speed = total distance / time time = 32+ 46 / 2.7 = 28 m/sec
Av velocity = total displacement / time total = S / t
S = sqrt( 32^2 +46^2) = 56 m
Av Velocity = 56/ 2,7 = 20.75 m/sec
with angle tan^-1 = 0.7 north west ( about 35 degrees north west)
