North component: y = 15.0 m * sin 55.0º = 12.3 m West component: x = 15.0 m * cos 55.0º + 7.00 m = 15.6 m
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
Hope this helps!
Answer:
eat, lignite, bituminous, and anthracite.
Explanation:
The stage depends upon the conditions to which the plant remains are subjected after they were buried: the greater the pressure and heat, the higher the rank of coal.
A :-) This only happens during the day, and at night the plant only undergoes respiration, not photosynthesis. Aerobic respiration happens when there is plenty of oxygen (normal level in air is 21%). Anaerobic respiration happens where there is less oxygen than this.
Answer: A = 154 m²
Explanation: First solve for radius r
Using circumference formula
C= 2πr
Derive to find r:
r = C / 2π
= 44 m / 2 ( 3.14 )
= 7 m²
Solve for area
A = π r²
= ( 3.14 ) ( 7 m )²
= 154 m²
<h3>When the temperature of a gas is held constant, if pressure increases then the Volume <em><u>decreases</u></em> </h3>
Option B is correct
Hope this will help....
