A). Scale.
You CAN measure volume with all the following except a scale.
There are 20 joules of useful energy.
In a nuclear decay, an unstable atom releases energy or particles to reach a more stable state. The energy released is equivalent to the difference between the mass of the original atom and the resultant atom and particles.
The events involved in the decay arranged in order to describe the process:
1. The nucleus is unstable.
2. The nucleus start to fall apart.
3. Radiation, mass, and energy are released.
4. The nucleus is stable.

Let's start by understanding what exactly a scientific question is. A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A good scientific question has certain characteristics.
