Answer:
J
Explanation:
= length of the rope connected = 13.4 m
= Angle made by the rope with the vertical = 72.4°
= height gained by the batman above the reference point
Height gained by the batman above the reference point is given as
= mass of batman = 89.5 kg
= acceleration due to gravity = 9.8 ms⁻²
Work done against gravity is same as the gravitational potential energy gained by batman and is given as
Inserting the above values
J
I believe the correct answer would be "A" energy source.
The answer is a which is zero
Answer: the answer is 35.4
Explanation: the formula is mass x acceleration = tension - weight
weight is (3kg x 9.8 m/s)
acceleration is 2 m/s
mass = 3kg
The answer is CH4, 2O2, ? CO2 H20.
In the reaction, the the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an atom (subscript) tells how many of that atom are in the molecule. The big number written in front of a molecule (coefficient) shows how many of that molecule there are. All the atoms in the products come from the atoms in the reactants.
The reactants are on the left side of the equation and the products are on the right. In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide
All the atoms in the reactants form the products so the mass of the reactants and the products is the same. No new atoms are created and no atoms are destroyed.
