Answer:
This is: False
Explanation:
Freud learned about his patients using the psychoanalytical method, and not by conducting laboratory experiments. The psychoanalytical method involves clients telling the therapist about their childhood memories, dreams, desires and relationships so that the therapist can uncover the client's unconscious thoughts, feelings and beliefs that might be influencing the client's behavior and leading to mental illness.
The psychoanalytical technique involves making unconscious behaviors, thought, beliefs and emotions conscious so that clients can face them and work through them with the guidance of the therapist. Therefore Freud, sought to learn about and cure treating mental illness in his clients by working through the root cause of their- childhood experiences and traumas, unconscious patterns, suppressed feelings, etc.
By using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg
<h3>Efficiency of a machine</h3>
- Efficiency is the percent of work put into a machine (input work) to that of the work done by the machine (output work).
- Efficiency of a machine is always less than 100% because the output work is always less than the input work because some of the input work is used to overcome friction.
Efficiency = work output/work input * 100%
Efficiency of fireplaces = 15%
Amount of food required to heat a room to 20°C = 15 kg
Assuming efficiency of 100%, amount of wood required will be X kg:
X = 15% * 15 kg
X = 2.25 Kg
By switching to woodstoves which are 75% efficient, amount of wood required will be Y kg:
Y = 2.25 kg / 75%
Y = 3 kg
Therefore, by using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg
