Answer:
The weights are 1 kg, 3kg, 9kg and 27kg.
Explanation:
The weights are 1 kg, 3kg, 9kg and 27kg.
1+3+9+27= 40
27+9+3= 39
27+9+3-1=38
27+9+1=37
27+9=36
27+9-1=35
27+9+1-3=34
27+9-3=33
27+9-3-1=32
27+3+1=31
27+3=30
27+3-1=29
27+1=28
27
27-1=26
27+1-3=25
27-3=24
27-3-1=23
27+3+1-9=22
27+3-9=21
27+3-9-1=20
Like this all the weights from 1 to 40 kg can be made using 1,3,9 and 27 kg.
D is the answer because of the solar phonominals
Hey there!
In a gas state, particles have lots of energy, so they move around very rapidly, hitting each other and flowing around, that's why you see them moving so freely. Because they have so much energy, the substance is likely to be harder, as it can obtain more thermal energy, or heat.
Hope this helps!
Distance of fall = (1/2) · (acceleration of gravity) · (time)²
= (1/2) · (1.63 m/s²) · (9 sec)²
= (0.815 m/s²) · (81 sec²)
= 66 meters .
On Earth ... IF there were no air ... the feather would fall
397 meters in the same amount of time !
