an object with a mass of 300 kg is observed to accelerate at the rate os 4m/s² what is the total force required

75 Newton

Explanation:

In order to find the force of the object, you must remember that the equation N = (mass x acceleration). Therefore meaning you would divide 300 kilograms, the mass, by 4 meters per second (squared), the acceleration.

the answer is d : ) have a good da

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
