¿Qué energía cinética posee una pelota de tenis de 65 g que se sirve a una velocidad de 200 km / h?
vekshin1

Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.

vovikov84 [41]

Answer:

Explanation:

density of galaxies would be \frac{1}{0.27^3} times higher which is equal to 50.81.

It means  in a cube that today contains one galaxy the size of the Milky Way, we would instead find 50.81 galaxies this size.

You can round this off to 52

Shalnov [3]

Answer:

T_F=\frac{9}{5}(T_K-273)+32

Explanation:

Since the temperature in degrees Fahrenheit in terms of the Celsius is given by the formula T_F=\frac{9}{5}T_C+32 and the temperature in degrees Celsius in terms of the Kelvin temperature is given by the formula T_C=T_K-273, we can use the second formula and substitute it straight into the first formula (since a simplification is not being asked), obtaining T_F=\frac{9}{5}(T_K-273)+32.

g calculate the effectiveness radiation dosage in sieverts for a 79 kg person who is exposed 6.8x10^9
Elza [17]

Answer:

The answer is "\bold{dosage = 0.031 rem}"

Explanation:

please find the complete question in the attached file.

Given value:

m = 79\  kg  \\\\n = 3.4 \times  10^9 \\\\E = 5.5  \times  10^{-13} \\\\ RBE = 15

\to E = n E\\

        = 3.4  \times  10^9  \times  5.5  \times  10^{-13} \\\\      = 1.87 \times  10^{-3}

\to E(absorbed) = 1.87  \times 10^{-3}  \times  0.87 = 1.63  \times  10^{-3}

calculating the radiation absorbed per kg:

= \frac{1.63  \times  10^{-3}}{79}  \\\\ = 2.06  \times  10^{-5} \\\\ = 0.00206 \  rad

\to Dosage = 0.00206  \times  15 \\

                 = 0.031 \ \ rem
