Answer:
2200 W
Explanation:
Use the given relation between current, voltage, and power to find the power requirement:
P = IV
P = (20 A)(110 V) = 2200 W
Answer:
a) 
b)
c)
Explanation:
a) Let's calculate the work done by the rocket until the thrust ends.

But we know the work is equal to change of kinetic energy, so:


b) Here we have a free fall motion, because there is not external forces acting, that is way we can use the free-fall equations.

At the maximum height the velocity is 0, so v(f) = 0.

c) Here we can evaluate the motion equation between the rocket at 25 m from the ground and the instant before the rocket touch the ground.
Using the same equation of part b)


The minus sign of 25 means the zero of the reference system is at the pint when the thrust ends.

Explanation:Image result for buildings designed to partially heat rooms by passive solar heating rely on
A strictly passive design will use the three natural heat transfer modes exclusively—conduction, convection, and radiation. In some applications, however, fans, ducts, and blowers may help with the distribution of heat through the building
Answer:
A Choreographer designs and directs the dance or stylized movement in musical productions, working closely with the director and musical director. A choreographer works with dancers to interpret and develop ideas and transform them into the finished performance.
Explanation:
Width * Length * Thickness * Density = Weight.
48″ * 96″ * . 1875″ * 0.284 lb/in3 = 245 lb.
