Answer:
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects
The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!
Gravitational force is the force that attracts to objects with mass. ... This forces tries to pull masses together, that is why attractive in nature. For example: When ball is thrown upwards it always come downwards after a certain height because the ball is pulled or attracted by the Earth's gravitation la force.

Answer:
The answer is
<h2>2.63 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of silver = 0.25 cm³
density = 10.5 g/cm³
The mass is
mass = 10.5 × 0.25 = 2.625
We have the final answer as
<h3>2.63 g</h3>
Hope this helps you
Well the first thing you need to know is how much energy that 1g methanol release which is fixed value
Methanol CHOH is 17000 j/g
so the energy released when 10.0g of methanol is burned
=10x 17000
=170000 j
Answer:
B) water and salt is the result of neutralization reaction
