Thea uses a hairdryer to dry her hair. The hairdryer has an efficiency of 0.5 and the total input energy is 180 kJ. How much of the energy supplied is wasted? Give your answer in joules
90kJ of the energy supplied to the hair dryer is wasted.
Efficiency is the ratio of output to input. It is given by:
Efficiency = output / input
Given an efficiency of 0.5 and the total input energy is 180 kJ. Hence:
Efficiency = output / input
0.5 = output / 180 kJ
Output = 90 kJ
Amount of wasted energy = Input - output = 180kJ - 90kJ = 90kJ
Therefore 90kJ of the energy supplied is wasted.

Examples of mediums that waves can travel through are _______ Select ALL that apply.
A. Air
B. Water
C. Ground
D. Metal
Answer:
air and water
Explanation:
The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through. The particles in a medium become disturbed and pass on this disturbance to the next one, and so on. So, the disturbance caused by the particles can travel through a medium such as air, ocean water, land, violin strings, Slinky coils, etc. Sound waves can travel through solids, liquids, or gases.

How does alpha particles transfer energy to their surroundings?
A rock is thrown upward with a speed of 2.0m/s.
a. How long will it take the rock to reach the peak?
b. What is the maximum height it can reach?
Hi there!
(A)
When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:
vf = vi + at
vf = final velocity (0 m/s)
vi = initial velocity (2 m/s)
a = acceleration (in this situation, due to gravity = 9.8 m/s²)
t = time (s)
0 = 2 + (-9.8)t
2/9.8 = t = .204 sec
(B)
Use the equation:
d = vit + 1/2at²
d = 2(.204) + 1/2(-9.8)(.204²)
d = .204 m

transivity, reflexivity, and identity refer to what kind of reasoning?
Deductive reasoning. Deductive reasoning implies the use of a given set of facts or data to deduce other facts, by reasoning logically. It rearranges information that is already known into new statements or truths. Hence transitivity, reflexivity, and identity refer to it and are necessary elements.
What are deductive reasoning and examples?Deductive reasoning is a type of deduction used in science and in life. It is when you take two true statements, or premises, to form a conclusion. For example, A is equal to B. B is also equal to C. Given those two statements, you can conclude A is equal to C using deductive reasoning.
