A) To lift a similar chair to a height of 80 cm, you would need 32 joules.
b) The amount of energy that would be needed to lift a chair that weighs 2kg to a height of 40 cm would be 8 joules.
Answer:
option c is the correct one according to me......
Answer:
Step-by-step explanation:
Real life = 8m = 8000mm
Drawing = 4mm
we can take the ratio of the two values (but be sure that they both have the same units, this is why it is necessary to convert 8m to 8000mm OR you can convert 4mm to its value in meters)
we can also write this as:
so the drawing's scale factor is:
This means that if length of the living room in the drawing is multiplied by 2000 it will be of the same length as the living room in real life.
