yanalaym [24]

Answer:

The answer to your question is below

Explanation:

Metals lose electrons and Nonmetals gain them.

a. Ra is in group IIA it will lose electrons, the ion will be Ra⁺²

b. Br is in group VIIA it will gain electrons, the ion will be Br⁻¹

c. In is in group IIIA it will lose electrons, the ion will be In⁺³

d. Te is in group VIA it will gain electrons, the ion will be Te⁻²

e. Ca is in group IIA it will lose electrons, the ion will be Ca⁺²

f. As is in group VA it will gain electrons, the ion will be As⁻³

g. Al is in group IIlA it will lose electrons, the ion will be Al⁺³

h. Rb is in group IA it will lose electrons, the ion will be Rb⁺¹

A baseball player hits a ball. Which is the best description of the energy of the ball as it flies over the pitcher’s head?

Elan Coil [88]

The right option is; b. mechanical

Mechanical energy is the best description of the energy of the ball as it flies over the pitcher’s head.

Mechanical energy is the energy that an object acquires due to its position or due to its motion. From the question, the baseball player has chemical potential energy (stored as food) which is transformed into work. As the baseball player hits the ball, there is energy exchange in which the ball acquires energy to perform its work. The energy obtained by the ball upon which work is done is called mechanical energy.
