Well mass=density times volume so .0065x260= 1.69

So your answer is 1.69 :)

The answer is definitely letter C. They are both located in the nucleus. Their summation define the mass of one (1) atomic mass unit of a particular element. For example, for carbon atom it has 6 protons and 6 neutrons. Therefore the atomic mass of carbon is 12.

If the velocity of a pitched ball has a magnitude of 47.0 m/s and the batted ball's velocity is 50.5 m/s in the opposite directi
Naya [18.7K]

Answer:

The magnitude of change in momentum of the ball is 97.5 m and impulse is also 97.5 m

Explanation:

Given:

Velocity of a pitched ball v _{i} = 47 \frac{m}{s}

Velocity of ball after impact v_{f}  = -50.5 \frac{m}{s}

From the formula of change in momentum,

  \Delta P = m (v_{f} -v_{i}  )

Here mass is not given in question,

Mass of ball is m

Change in momentum is given by,

\Delta P = m (-50.5 -47)

\Delta P = -97.5 m

Magnitude of change in momentum is

\Delta P = 97.5 m

And impulse is given by

 J = \Delta P

J = -97.5 m

So impulse and

Therefore, the magnitude of change in momentum of the ball is 97.5 m and impulse is also -97.5 m
