Answer:
E = K Q / R^2
E1 = K Q1 / R1^2 = K * (-6.39 E-9) / .4^2 = -K 39.9 E-9
E2 = K Q2 / R2^2 = K * 3.22 E-9 / .25^2 = K 51.5 E-9
Field will point to right of P since E2 (positive) stronger
E = K (E2 - E1) = 9.0 E9 * (51.5 - 39.9) E-9 = 104 N/C
Answer:
Bromine
Explanation:
because it is present in 17th group that gives valence electrons as 7 in its last orbit
The correct answer is false I just took the test.
Wind power is produced from the
wind turbines or sails that uses air flow to convert it into mechanical power.
It is an alternative to fossil fuel burning, it is all around, renewable,
clean, produces no greenhouse gases and uses little land. The advantages of
wind power have been greatly praised by many. However, it has disadvantages.
Wind power especially at farm is noisy and may spoil the view for their
neighboring people. Also the amount of electricity depends on the strength of
the wind. If no wind is around, no electricity is produced.
