As sources of electrical power, windmills now account for only about 2,500 megawatts nationwide, but production is almost expect

ed to double by the end of the year, which would provide enough electricity for 1.3 million households.
a. almost expected to double by the end of the year, which would provide
b. almost expected that it will double by the end of the year, thus providing
c. expected that it will almost double by the end of the year to provide
d. expected almost to double by the end of the year and thus to provide
e. expected almost to double by the end of the year, which would thus be providing

Answer: C

Explanation:

Production is expected that it will almost double by the end of the year is the answer because production in this context relates to a numerical quantity which is a function of time.

Therefore the probability there is on whether production will almost double to provide enough electricity and not if production will occur.

a bus travels 4 km due north and 3 km due west going from bus station a to bus station b. the magnitude of the bus displacement
ladessa [460]

Answer:

5km

Explanation:

Magnitude of displacement is found by getting the resultant. Resultant is same as the bypotenuse hence

R=\sqrt {{x^{2}+y^{2}} where x is the displacement in west direction and y is displacement in North direction. Substituting x with 3km and y with 4 km then

R=\sqrt {{3^{2}+4^{2}}=5km

you apply the same amount of heat to five grams of water and five grams of aluminum the temperature of the aluminum increases mo
Triss [41]
I can conclude that the aluminum heats up faster then the water, since how they are made up is more different, each has a different compound to it, plus water is more denser<span />

A 3.90 kg block is in equilibrium on an incline of 31.0◦. The acceleration of gravity is 9.81 m/s2 . What is Fn of the incline o
storchak [24]

Answer:

Explanation:

The sum of the pore along the plane is expressed according to Newton's law

Fn-Ff = ma

Fn is the moving force

Ff = nR = frictional force

m is the Mass

a is the acceleration

Substitute the given values

Fn - nR = ma

Fn - tan31°(mgcostheta) =3.9(9.8)

Fn - tan31(3.9(9.8)cos31) = 3.9(9.8)

Fn - tan31(38.22cos31)= 38.22

Fn - 32.76tan31 = 38.22

Fn-19.68 = 38.22

Fn = 38.22+19.68.

Fn = 57.90N

Hence Fn (moving force) of the inclined block is 57.90

What is the difference between an elastic and inelastic collision
barxatty [35]

Answer:

In an elastic collision, the total kinetic energy is conserved, while in an inelastic collision, it is not

Explanation:

Let's define the two types of collision:

- Elastic collision: an elastic collision is a collision in which:

1) the total momentum of the system is conserved

2) the total kinetic energy of the system is conserved

Typically, elastic collisions occur when there are no frictional forces acting on the objects in the system, so that no kinetic energy is lost into thermal energy. An example of elastic collision is the collision between biliard balls.

- Inelastic collision: an inelastic collision is a collision in which:

1 ) the total momentum of the system is conserved

2) the total kinetic energy of the system is NOT conserved

In an elastic collision, part of the total kinetic energy is lost (=converted into thermal energy) due to the presence of frictional forces. An example of inelastic collision is the accident between two cars, in which part of the energy is converted into heat.
