6 0

Answer:

  100 J

Step-by-step explanation:

Kinetic energy is jointly proportional to mass and the square of the velocity.

  KE = 1/2mv²

  KE = 1/2(50 kg)(2 m/s)² = 100 J

Juan has a kinetic energy of 100 joules.

Answer:

∠ PQR = 70°

Step-by-step explanation:

The tangent- tangent angle PQR is half the difference of the intercepted arcs.

minor arc PR = 360° - 250° = 110°

Then

∠ PQR = \frac{1}{2} (250 - 110)° = \frac{1}{2} × 140° = 70°

Answer:

t \approx 750550.12\,yr

Step-by-step explanation:

The time constant of the isotope is:

\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}

\tau \approx 1.876 \times 10^{9}\,yr

The decay of the isotope is described by the following model:

\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }

Now, the time is cleared in the equation:

t = -\tau \cdot \ln \frac{m}{m_{o}}

t = - (1.876\times 10^{9}\,yr)\cdot \ln 0.9996

t \approx 750550.12\,yr
