A rolling ball travels 7.3m in 3.7s. What was the velocity of the ball?

Velocity of rolling ball = 1.97 m/s (Approx.)

Explanation:

Given:

Distance travel by rolling ball = 7.3 meter

Time taken by rolling ball = 3.7 seconds

Find:

Velocity of rolling ball

Computation:

Velocity = Distance / Time

Velocity of rolling ball = Distance travel by rolling ball / Time taken by rolling ball

Velocity of rolling ball = 7.3 / .37

Velocity of rolling ball = 1.9729

Velocity of rolling ball = 1.97 m/s (Approx.)

i think that d. wind is the answer.   i missed the question when i answered a. currents.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
