Why do astronomers use the astronomical unit to measure distance of the solar system?

Physics
1 answer:
Ivahew [28]3 years ago
4 0
An astronomical unit is the measure of the center of the Earth to the center of the sun. 

Because our solar system is so vast, using mere miles is ridiculous, because they are too small to be helpful and the numbers will be in the billions. Astronomical units make it easier to think in small amounts.

Hope this helps :)

Explain the relationship between speed and steepness of the slope of the line on the distance-versus-time graph
balandron [24]

Explanation:

A distance-versus-time graph gives the distance an object has traveled after a given time.

In a distance-versus-time graph the slope represents the the speed of the object because rise/run is

  \frac{\Delta distance }{\Delta time}=speed.

And how steep the slope of the distance-versus-time graph is tells us how fast an object is moving; steeper the slope greater the speed. For example, a graph with slope 10 represents a greater speed than a graph with slope 2.

So the steepness of the slope of the distance-versus-time is the speed of the object, and greater the slope greater is the speed.

Problem 10.64 the maximum energy a bone can absorb without breaking is surprisingly small. for a healthy human of mass 67 kg , e
kvasek [131]

Answer: h = 0.30 m

Explanation:

A person jumping from height h would possess potential energy = m g h

which will convert completely into kinetic energy as person hits the ground. Now, the maximum energy absorbed by the person can be = 200 J

m = 67 kg

g = 9.8 m/s²

⇒ m g h = 200 J

⇒ h = 200 J / (67 kg × 9.8 m/s²) = 0.30 m

Hence, a person can land safely on both legs without breaking them from a height of 0.30 m only.

What is the magnitude of the net force acting on a 2.0 x10^3 kilogram car?
Tatiana [17]
Answer:  
Acceleration= final velocity - initial velocity / time
 = (15 - 0)/ 5
 = 3 m/s^2
 Force = mass X acceleration
 = 2 X 10^3 X 3
 = 6 X 10^3 N

How is precipitation related to high and low pressure air?
Ymorist [56]
A pressure system is a relative peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg). High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances jargon as well as the amount of solar heating or radiational cooling an area receives. Pressure systems cause weather experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes through the day, whereas high-pressure systems normally associated with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day. Pressure systems are analyzed by those in the field of meteorology within surface weather maps.
