Answer:
IT would be C.electromagnetic waves move faster than mechanical waves.
Explanation:
This is triggered by an activity known as heliotropism, or solar tracking. Special motor cells at the bases of the flowerbuds shrink or enlarge as they absorb water, which moves their faces toward the sun.
Most likely the answer is b
Answer:
The electric field at point a =( 0.232N/c)k
Explanation:
E = E1+E2=(6/2Eo)K+(-6/2Eo)[1-(2/(sqrtz^2+R^2)k
E= 6z/2Eo(sqrtz^2+R^2)k
E= (4.5×10^-12)×(2.56×10^-2) /2(8.85×10^-12)sqrt(2.56×10^-2)^2+(1.30×10^-2)^2k
E= 1.152×10^-13/(1.77×10^-11)×(2.8×10^-2)k
E= 1.152×10^-13/(4.956×10^-13)k
E=( 0.232N/c)K
That is nonsense, also known as jibberish
