Answer:
80 degress is needed to boil 200g of water from 30 degress
Sunlight emits more energy than artificial light. Sunlight is better and healthier than most artificial lights and helps plants to grow more.
Answer:
Clouds are made up of tiny water droplets. ... As more and more droplets join together they become too heavy and fall from the cloud as rain. Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

Answer:
0.855 N
Explanation:
Using
F = BILsinФ.................... Equation 1
Where F = magnitude of the force exerted on the wire, B = magnetic Field, I = current, L = Length of the wire in the magnetic Field, Ф = angle between the wire and the magnetic field.
Given: B = 0.95 T, I = 15.0 A, L = 2r, r = radius = 3.0 cm = 0.03 m L = 2×0.03 = 0.06 m, Ф = 90° (perpendicular)
Substitute into equation 1
F = 0.95(15)(0.06)sin90°
F = 0.855 N.
Hence the magnitude of force that is exerted on the wire = 0.855 N
