Answer:
C
Explanation:
The density is what determines if it will float. Lower densities float, while higher densities sink. Density takes mass and volume into account.
One of the most common devices for measuring temperature<span> is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid.</span>
Explanation:
Work = change in energy
W = ΔKE
W = ½ m (v² − v₀²)
W = ½ (1750 kg) ((27 m/s)² − (15 m/s)²)
W = 441,000 J
W = 441 kJ
<h2>Answer:</h2>
Entropy is the reason of worrying about world energy sources.
<h3>Explanation:</h3>
- Entropy is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- The amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
- For example , There are some reactions which are irreversible because some of the energy in the reaction is lost to environment instead of converting totally to the products.
- This lost of energy is entropy.
- Due to which the energy of universe is losing irreversibly.
- That's why we worry about world energy sources.
Samburu's weight is (mass x gravity) = (1650kg x 9.8 m/s²) = 16,170 Newtons.
Samburu's contact area with the ground is (0.25 m²/hoof) x (4 hoofs) = 1 m² .
Pressure = (force) / (area) = (16,170 Newtons) / (1 m²) = 16,170 Pascal .
