Answer:
0
Explanation:
Weight = mass x gravity
if gravity = 0 then Weight =0 as well
Yes, you can chemically change or alter DNA
Answer:
T= 5.18N
Explanation:
u = mass of chord / length of chord
u = 0.49/ 7.3
u = 0.067 kg/m
Velocity of sound waves (v) =length of chord / time taken for wave to travel
v = 7.3 / 0.83 = 8.795m/s
Tension is calculated below using the formula
T = v² * u
T = (8.795)² x 0.067
T= 5.18N
