The air sealed between two panes of glass in some windows helps to reduce the flow of heat passing through the window. Even though the windows are more expensive to build, that little bit of trapped air in there is a very effective INSULATION. It makes the house easier to keep warm in Winter, and easier to keep cool on Summer, and both of those save on the cost of gas or electricity for the house.

The answer is: reduce the flow of heat passing through the window.

A double glazing window or insulating glass consists of two glass window panes separated by a spacer bar and seals to create a hermetically-sealed environment. Space between glass panes is filled under vacuum with either dehydrated air or an inert gas to improve insulation and prevent condensation within the unit. The physical properties of the dehydrated air used in the space between glass panes mean that it transmits less heat than normal air, this is because the molecules of dehydrated air are relatively inert and therefore have a lower thermal conductivity.

suter [353]

Answer:

e. Decreased; Increased

Explanation:

The market equilibrium refers to the condition in which the price and the quantity are in equilibrium if the conditions of supply (what the producers offer) and demand (what the consumers buy) don't change.

In this case we have that as the other kids decide to sell more lemonade the amount of lemonade is going to increase (equilibrium quantity) and because of this the price is going to decrease (equilibrium price).

Then when the other kids open theirown lemonade stand, the equilibrium price descreased and the equilibrium quantity increased.

Suppose you give a 10 Newton push to Ryan on skis (he weighs 50 kg), how much will he accelerate?

Talja [164]

Well we can just use F=ma. The force is 10N, the mass is 50 kg, solve for a. Well since we kg and N, no conversion is necessary. So just plugging in the numbers, we get

10N = 50 kg · a

$\frac{10N}{50kg}=a$

A newton is just $\frac{kg·m}{s^{2}}$

$a=\frac{\frac{10kg·m}{s^{2}}}{50kg}$

The s^2 and 50 kg you multiply

$a=\frac{10kg·m}{50kg·s^{2}}$

The kg's cancel and 10/50 is 1/5

$\frac{1}{5}·\frac{m}{s^{2}}$

So the acceleration is 1/5 m/s^2

A 0.300 kg ball, moving with a speed of 2.5 m/s, has a head-on collision with at 0.600 kg ball initially at rest. Assuming a per

FrozenT [24]

Answer:

1.25 m/s

Explanation:

Given,

Mass of first ball=0.3 kg

Its speed before collision=2.5 m/s

Its speed after collision=2 m/s

Mass of second ball=0.6 kg

Momentum of 1st ball=mass of the ball*velocity

=0.3kg*2.5m/s

=0.75 kg m/s

Momentum of 2nd ball=mass of the ball*velocity

=0.6 kg*velocity of 2nd ball

Since the first ball undergoes head on collision with the second ball,

momentum of first ball=momentum of second ball

0.75 kg m/s=0.6 kg*velocity of 2nd ball

Velocity of 2nd ball=0.75 kg m/s ÷ 0.6 kg

=1.25 m/s
