What symbol represents energy that moves from a hot object to a cooler object?

1 answer:

6 0

The correct answer is
<span>C) Q

In fact, the symbol Q represents the heat, which is the form of energy transferred from a hot object to a cooler object. Heat generally refers to the energy related to the motion of the particles, and it is related to the temperature of an object: the higher the temperature of an object, the faster the particles of the object move, and so the object can transfer more energy (as heat) to other objects with lower temperature.</span>

Answer:

True

Explanations

Temperature is the degree of coldness or hotness of a body, usually organism rarely adapt to extreme temperature value of below 0°C or above 43°C,organisms usually respond to cold weather by hibernation or estivation for hot weather also extreme temperature causes migration of birds if they can't survive such place like the artic tern that travel thousands of miles,

Answer:

11.56066 m/s

Explanation:

m = Mass of person

v = Velocity of person = 13.4 m/s

g = Acceleration due to gravity = 9.81 m/s²

v' = Velocity of the person in the second

The kinetic and potential energy will balance each other at the surface

$\dfrac{1}{2}mv^2=mgh\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow h=\dfrac{13.4^2}{2\times 9.81}\\\Rightarrow h=9.15188\ m$

Height of the cliff is 9.15188 m

Let height of the fall be h' = 2.34 m

$\dfrac{1}{2}mv'^2+mgh'=mgh\\\Rightarrow v'=\sqrt{2g(h-h')}\\\Rightarrow v'=\sqrt{2\times 9.81(9.15188-2.34)}\\\Rightarrow v'=11.56066\ m/s$

The speed of the person is 11.56066 m/s

Sort the chemical equations based on the chemical reactions they represent.

Svetradugi [14.3K]

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,

ABC → A + B + C

Specific Examples are as,

Water → Hydrogen + Oxygen

2 H₂O → 2 H₂ + O₂

Calcium carbonate → Calcium oxide + Carbon dioxide

CaCO₃ → CaO + CO₂

While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,

A + B + C → ABC

Specific Examples are as,

Iron + Oxygen → Iron Oxide

2 Fe + 3 O₂ → 2 Fe₂O₃

Sodium + Chlorine → Sodium chloride

2 Na + Cl₂ → 2 NaCl

Sulfur + Oxygen → Sulfur dioxide

S + O₂ → SO₂

Potassium + Chlorine → Potassium chloride

2 K + Cl₂ → 2 KCl
