Kinetic of automobile
Mass m = 1,250 Kg; V = 11 m/s
Formula: K.E = 1/2 mV²
K.E = 1/2(1,250 Kg)(11 m/s)²
K.E = 75,625 J
Speed required for insect to have the same kinetic energy as automobile
Mass of insect = 0.72 g convert to Kg m = 7.2 x 10⁻⁴ Kg
K.E = 1/2 mV² Derive V =?
V = 2 K.E/m
V = √2(75,625 J)/7.2 x 10⁻4 Kg
V = √2.1 x 10⁸ m²/s²
V = 14,491.34 m/s (velocity of insect)
The percentage of the iceberg that is visible above the water's surface will be 11.5%.
<h3>What is density?</h3>
Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
Density of ice = 917 kg/m³
Density of the seawater=1025 kg/m³
The ratio by which the iceberg submerge is found as;
Hence,89.5 % of the ice is submerged.
The percentage of the iceberg that is visible above the water's surface is;
⇒1-.89.5 %
⇒11.55 %
Hence, the percentage of the iceberg that is visible above the water's surface will be 11.5%.

<span>Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. </span><span>All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet. i don't know if this is right but i hope it helps</span>
The transfer of heat that utilizes or occurs in the form of wave, would be B. Radiation. As heat, can be emitted in the form of waves which constitute or make up the electromagnetic spectrum, specifically these include UV Rays from the sun for instance.
