Answer:
a) p = 25.8 10⁻¹² C m
, b) The direction of the dipole moment is directed from the negative to the positive charge, c) E = 4.65 10² N/C
Explanation:
a) The dipole moment is
p = 2qa
p = 2 4.30 10⁻⁹ 3.00 10⁻³
p = 25.8 10⁻¹² C m
b) The direction of the dipole moment is directed from the negative to the positive charge, that is, in the opposite direction to the electric field.
c) The torque is
τ = p x E
τ = p E sin θ
E = τ / p sin θ
E = 7.20 10⁻⁹ /(25.8 10⁻¹² sin 36.9)
E = 4.65 10² N/C
We calculate
τ = 15.49 10⁻¹² 4.7 10²
τ = 7.28 10⁻⁹ N m
Answer:
Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". ... So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
The surface is the main area that is exposed to the cold.
