Answer:
8.96 g/mL
Explanation:
density = mass / volume
density = 134.3g / 15.0 mL
density = 8.96 g/mL
<h3>A. an acidic............</h3>
Answer: When the air particles inside the balloon become colder, they slow down and do not hit the inside of the balloon as often, so the balloon's volume decreases.
Answer:
We have the final answer as

Explanation:
To find the energy of a photon of this light we use the formula
<h3>E = hf</h3>
where
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
f = 7.08×10¹⁴ Hz
We have
E = 7.08×10¹⁴ × 6.626 × 10-³⁴
We have the final answer as

The closer they are, the greater the gravitational pull they will have on each other. Size also affects the gravitational pull of the celestial bodies because the larger the body the greater the pull it will have.
