Answer:

A = 2,8333 s

Explanation:

El periodo es definido como el tiene que toma de dar una oscilación.

En este caso realiza varias osicilacion por lo cual debemos encontrar el promedio del perdono.

T = t/n

calculemos

A = 34,0/ 12,0

A = 2,8333 s

Celina has a water sample that’s contaminated with salt and microorganisms. Which method should she use to purify the water?

Dmitry_Shevchenko [17]

Celina should perform the following method to get pure water:

Boil the water in a pan, as the water boils it changes into gas (water vapours) these vapours should be cooled down through the process of condensation which changes gas into liquid form, Through this process germs would be killed due to high temperature and the salt will remain in the pan as salt has higher boiling point than water,

A pitcher claims he can throw a 0.148-kg baseball with as much momentum as a 2.00-g bullet moving with a speed of 1.50 ✕ 103 m/s

Svetlanka [38]

(a) The mass of the bullet is $m_b = 2.00g=0.002 kg$ and its speed is $v_b = 1.5 \cdot 10^3 m/s$ , so its momentum is
$p=m_b v_b = (0.002 kg)(1.5 \cdot 10^3 m/s)=3 kg m/s$

The pitcher claims that he can throw the ball with the same momentum p of the ball. Since the mass of the ball is m=0.148 kg, this means that the velocity of the ball must be:
$v= \frac{p}{m}= \frac{3 kg m/s}{0.148 kg}=20.3 m/s$

(b) The kinetic energy of the bullet is:
$K_b = \frac{1}{2} m_b v_b^2= \frac{1}{2}(0.002 kg)(1.5 \cdot 10^3 m/s)^2=2250 J$

while the kinetic energy of the ball is:
$K= \frac{1}{2}mv^2= \frac{1}{2}(0.148 kg)(20.3 m/s)^2=30.5 J$

So, the bullet has greater kinetic energy than the ball.
