Is radioactivity on the Earth something relatively new? Defend your answer.

Whether the radioactivity on the Earth is something relatively new.
Answer to Problem 1RQ
No, the radioactivity on the Earth is not new.
Explanation of Solution
The disintegration of alpha, beta, and other radioactive particles from unstable nuclei and spontaneous emission of the radioactive wave is termed as radioactivity. In this process, the unstable atoms break down into stable atoms and emit some radiation. The reason behind the instability of the nuclei is the imbalance of proton and neutron in the nuclei.
The sun has been providing thermal energy by the principle of radioactivity. And it has been blowing such radioactive elements in the space from the beginning. This radiate energy provides heat and light to the Earth through radiation. So the concept of radioactivity is a very old concept.
Conclusion:
Therefore, the radioactivity on the Earth is not new.

- Please draw the sketch and a FBDarrow_forward8.30 Asteroid Collision. Two asteroids of equal mass in the aster- oid belt between Mars and Jupiter collide with a glancing blow. Asteroid A, which was initially traveling at 40.0 m/s, is deflected 30.0° from its original direction, while asteroid B, which was initially at rest, travels at 45.0° to the original direction of A (Fig. E8.30). (a) Find the speed of each asteroid after the collision. (b) What fraction of the original kinetic energy of asteroid A dissipates during this collision?

- Please draw a sketch and a FBDarrow_forward8.69 Spheres A (mass 0.020 kg), B (mass 0.030 kg), and C (mass 0.050 kg) are approaching the origin as they slide on a frictionless air table. The initial velocities of A and B are given in Fig. P8.69. All three spheres arrive at the origin at the same time and stick together. (a) What must the x- and y-components of the initial velocity of C be if all three objects are to end up moving at 0.50 m/s in the +x-direction after the col- lision? (b) If C has the velocity found in part (a), what is the change in the kinetic energy of the system of three spheres as a result of the collision?

The two vehicles remain locked together after the collision. (a) What is the velocity (magnitude and direction) of the two vehicles just after the collision? (b) At what speed should the truck have been moving so that both it and the car are stopped in the collision? (c) Find the change in kinetic energy of the system of two vehicles for the situ- ations of parts (a) and (b). For which situation is the change in kinetic energy greater in magnitude?arrow_forward

Just before impact, the ball is traveling horizontally to the right at 40.0 m/s; when it leaves the bat, the ball is traveling to the left at an angle of 30° above horizontal with a speed of 52.0 m/s. If the ball and bat are in contact for 1.75 ms, find the horizontal and vertical components of the average force on the ball.arrow_forwardL1=5.2m L2=0.5m L3=1.7m L4=0.6m L5=0.5m L6=0.5m V2=5.4m/sarrow_forwardM1=0.45M2=1.9M3=0.59arrow_forward
