We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
I just got this question not to long ago but to answer your question the primary function of the respiratory system is to exchange oxygen<span> and carbon dioxide. Inhaled </span>oxygen enters the lungs<span> and reaches the alveoli. </span>Oxygen<span> passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.</span>
Answer:
1.5 Amp is rated for 5 W so it would not be possible
Answer:
1000kg
Explanation:
We can use the equation "p=mv"
- p is the momentum in kg m/s
- m is the mass measured in kg
- v is the velocity measured in m/s
If we rearrange the equation to find mass (m), then the equation becomes:
m=p/v
We can substitute in the values of p and v as they are already given in the question.
So, now we just substitute in the values to get our answer.
m=p/v
m=25,000/25
m=1000kg
