Explanation: Triangle whose sides are midpoints of sides of triangle ABC has a perimeter 45. How long is perimeter of triangle ABC? Triangle ABC Construct a triangle ABC is is given c = 60mm hc = 40 mm and b = 48 mm analysis procedure steps construction; The sides 3 The sides of an equilateral triangle are 9.4 cm, :) A right-angled triangle (also called a right triangle) is a triangle with a right angle (90°) in it. The right angled triangle is one of the most useful shapes in all of mathematics! (It is used in the Pythagoras Theorem and Sine,
Short Answer:
buoyancy
Long answer:
An object submerged in water displaces water according to how much it weighs. In fact, the water will push upward against the object with a force equal to the weight of the water it displaces. For example, a bowling ball and a beach ball that are the same size will have the same volume. The bowling ball, however, is more massive and thus denser than the beach ball. In both cases, the water pushes up against the ball with a force equal to the weight of water it displaced. In the case of the bowling ball, it weighs more than the amount of water it displaced, so it sinks. The beach ball, however, displaces very little water and the air inside it is much lighter than the weight of the water it displaced, so it floats.When lifting something underwater, you have the help of water pushing the object upwards along with your own strength, which is why it's easier to pick up things underwater than on land.

Answer:
Conduction
Radiation
Radiation
Explanation:
When the door feels cold on the inside because it is cols outside, this type of heat transfer is called Conduction.
- Conduction is simply the movement of heat or cold (as the case may be), through a medium. An example of this is the warming of a fabric that is placed on a radiator, or heat movement through a pan to fry eggs.
When the sun shines through windows into a room and the room temperature rises, this type of heat transfer is called Radiation.
- Radiation is simply the transfer of heat or energy through space in form of particles or waves, light, x-rays, radio waves, etc. For example, the heat we feel when we stand close to a fire, gets to us through radiation. The sun emits radiation in form of heat, light and particles.
When the Earth's atmosphere is warmed by the sun's rays, this is also Radiation. This is because the sun's heat gets to the Earth's atmosphere in the form of radiation.
Siberia is much colder than Western Russia because ocean winds cannot reach Siberia. This wind is warm, which makes Western Russia warmer than Siberia.
Another factor is that Siberia has huge mountainous region preventing warm air from traveling North while cold Arctic air travels South.
