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: Mass of the object is 75 kg.
The heat energy lost or gained by a substance is given by the equation
Q = mCΔT, where
Q is the heat energy gained or lost by a substance,
m is mass (in grams),
C is the specific heat of the substance,
ΔT is the change in temperature (final temperature - initial temperature).
The joules given off by 617 grams of water cooling from 65°C to 28°C, given the specific heat of water as Cw=4.186 J/g*Co, is:
Q = mCwΔT
Q = (617)(4.186)(28 - 65)
Q = -95562.194
Negative means heat is lost, so 96000 J of heat was lost.
Answer: a) 24.2 rad/s² b) 6.95 rad/s
Explanation:
So the cylinder's moment of inertia is , where M is the mass of the cylinder and R is its radius.
The problem you have here is that the axle is modifying it, so we use the parallel axis theorem:
Therefore
where D is the distance from the center of mass to the axis which is a radius R
Next the Momentum with respect to the center of mass of the cylinder is
because there are no other forces rather than the cylinder's weight, now kg*m^2
a ) replace and find
b) we start by assuming that the energy is conserved because the cylinder is rolling without sliding:
so the potential energy is given by
now you have that the same amount is going to be equal to the kinetic rotational energy of the cylinder so
