Answer:
C
Explanation:
Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
1. X axis - type of sound; y axis - sound level (decibels)
2. whisper - 20 decibels; normal talking - 60 decibels; rock concert - 120 decibels
3. Normal talking is 40 decibels more intense. You can figure this out by subtracting the decibels of whispering from the decibels of normal talking (60-20)
4. The pain threshold is 120 decibels. This means the jet sounds could be painful because it is 140 decibels, or higher than the threshold.
Answer:
11.) red aka b
12.)orange aka a
13.)yellow aka c
14.) orange aka b
15.) last one aka c
Explanation:
11.) F=ma---> 75=0.445(a)--->a=168.5m/s^2
12.)F=ma---> 5,100=m(3)---->m=1,700kg
13.)F=ma---> 3.63=18.15(a)--->a=0.2m/s^2
14.)F=ma---->F=(2,030,000)(15)----->F=30,450,000n
15.) Doubling the mass doubles the acceleration
Option is c....bcz dna contains the base thymine and rna contains uracil
Answer:
All of them, except the gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury.
