Next the scientist should create a hypothesis to prove his findings hypothesis is what scientist use after an experiment to make sure that what they viewed in there experiment was correct. For example if they want to find a vaccine flue shot they have to do more reach on the ingredients to make sure it’s safe to the public
Answer:
Explanation:
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.
The test measures your knowledge in eight areas:
General Science - Life, earth, space and physical sciences
Arithmetic Reasoning - Ability to solve basic math and word problems
Word Knowledge - Ability to grasp the meaning of words through synonyms
Paragraph Comprehension - Ability to understand written material
Mathematics - Math concepts and applications
Electronics - Electrical current, circuits, devices and electronic systems
Auto and Shop - Car maintenance and repair, and wood and metal shop
Mechanical - Principles of mechanical devices, structural support, properties of materials
So the answer would be the Mathematics section
