The building sector plays a large role in the energy consumption which includes space heating or cooling, domestic hot water and electricity. Buildings with their long lifespan and huge amount of already existing buildings, makes revision in energy characteristics of a building constrained.

How long will a plane have to fly continuously with 900 miles per hour in order to cover the same distance as that from Earth to

hammer [34]

I'm not sure about the distance to the nearest star, but it's probably about 4 light-years (L-y).

1 L-y = 1.86 * 10E5 mi/sec * 3600 sec/hr * 24 hr/day * 365 day/yr

1 L-y = 5.9 *10E12 mi and 4 L-y = 2.3 *10E13 mi distance to star

2.3 * 10E13 mi / 900 mi/hr = 2.6 * 10E10 hr hours to star

2.6 * 10E10 hr / (24 hr/day) = 1.1 * 10E9 day days to star

1.1 * 10E9 day / 365 day/yr = 3 * 10E6 yr = 3 million years to star

A woman drives 200 miles west and then turns south and drives 375 miles. Her trip takes her 11.75 hrs. What is the woman's avera

FromTheMoon [43]

Answer:

The woman's average velocity during the trip is 36.2 miles/hour.

Explanation:

Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.

i.e velocity = $\frac{displacement}{time}$

From the given question,

Displacement = $\sqrt{200^{2} + 375^{2} }$

= $\sqrt{40000+140625}$

= $\sqrt{180625}$

= 425

The displacement of woman is 425 miles.

velocity = $\frac{425}{11.75}$

= 36.1702 miles/hour

The woman's average velocity during the trip is 36.2 miles/hour.

A baseball bat hits a baseball with a force of 100 newtons. What is the force and its direction exerted by the ball on the bat?

Brut [27]

Answer:

The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.

Explanation:

Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."

Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.

$F_{ab} = -\,F_{ba}$
