Answer:
1.28 m
Explanation:
You are given the initial speed that is 5 m/s. Since the coin is sent upwards, this means that the speed is positive according to the co-ordinate system in the y axis. Additionally, there is the gravity that curbs the coin in the opposite direction making the final speed becomes zero at the highest point, so the gravity takes negative sign.
So, from the explanation we have:
so, we use the following equation to find y (hight)
<u>Answer:</u> The energy released in the decay process is
<u>Explanation:</u>
The equation for the alpha decay of Ra-226 follows:
To calculate the mass defect, we use the equation:
Mass defect = Sum of mass of product - Sum of mass of reactant
We know that:
Putting values in above equation, we get:
(Conversion factor: 1 kg = 1000 g )
To calculate the energy released, we use Einstein equation, which is:
Hence, the energy released in the decay process is
