Answer:
The two different ways to measure gravitational potential energy is listed below:
Explanation:
- To measure the gravitational potential energy of the ball dropped from certain height we can use the formula as:
PE= mgΔh
where,
m= mass of the ball
g= gravity
Δh= change in height
- The second way is to follow the principal as:
Loss in PE = Gain in KE
∴ -ΔPE = ΔKE
- Height and mass is the major element that determines the gravitational potential energy of any object.
She could melt 75g of lead at 1637.5 C
Both are temples designed to inspire reflection, meditative thought and are places of significant art and design. The Ryoanji garden uses asymmetry, spacial composition, minimalism and little color that arranges three small islands in a perfectly kept graveled garden with a prominent cherry blossom; the stained glass window at Chartres Cathedral, however, uses light, complicated symmetrical patterns, figuration, lots of color on the two-dimensional form of the glass.

Answer:
Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.
Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.
Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.
Nonmetals are plentiful and useful. These are among the most commonly used:
Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.
Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.
Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.
