Answer:
C) The force experienced by the ball equals the force experienced by the club.
Explanation:
When the golfer strikes the ball with his club, the club exerts a force on the ball. Due to Newton's Third Law Of Motion [Every Action has an equal and opposite reaction], the ball also exerts an equal force on the club. However,
As the mass of the club is usually greater than the mass of the ball, it accelerates slower; While the ball way faster, following the equation : F=ma
Answer:
Less strongly attracted.
Explanation:
Potassium and sodium are both alkali metals. That means that they have the ability to be able to gather more valence electrons. They will both gain a positive particle. The potassium electron is less attracted because of the fact that now the sodium has a positive chargem and the electron has a negative charge.
It is given that total amount of oxygen in the reactants is 4 atoms to balance this chemical equation it is necessary that total number of reactant molecules should equal the total number of products.
Explanation:
The coefficients are found by counting each individual atom and atom numbers are same in reactants and products.
Without balancing the equation the formation is H2O and O2. The total number of oxygen in the product side is 3. Hence to balance this equation multiply H2O by 2 and O2 by 1. Thus the total of 4 O2 atoms will be formed on the product side.
Therefore, We can say that the coefficient 2 should be placed in front of water and and 1 in front of oxygen.
