Suppose that scientists discover an asteroid that is 2.0 AU from the sun. If 1 AU - 150 million km, how long would the asteroid'
Mice21 [21]

Answer:

2.84*10^-3 years = 0.00284*10^-3 years

Explanation:

To find the orbital period you use the following formula:

T=\sqrt{\frac{4\pi^2r^3}{GM}}

r: 2.0A = 2.0(1.5*10^11m)=3*10^11 m

G: Cavendish constant = 6.67*10^-11 Nm^2/kg^2

M: mass of the sun = 1.98*10^30 kg

T=\sqrt{\frac{4\pi^2(3*10^{11}m)^3}{(6.67*10^{-11}Nm^2/kg^2)(1.98*10^{30}kg)}}\\\\T=89839.27\ s

Next, you calculate the time in seconds of one Earth's year:

1\ year=365days*\frac{24\ h}{1\ day}*\frac{3600\ s}{1\ h}=31536000\ s

thus, you use this value to find the orbital period of the asteroid in Earth's year:

T=89839.27\ s*\frac{1\ year}{31536000\ s}=2.84*10^{-3}\ years

Sindrei [870]

Answer:

Producer innovation in a market economy.

Explanation:

It should be understood that there are millions of individuals and companies that produce products that look alike. For example, there are many companies that produce balls that are of the same size, shape and colour. This is the reason why each producer has a mark or logo or sticker that it puts on its product. This is done to differentiate it's product from others that look exactly the same. This logo or mark is known as label.

In this case, the label will distinguish a producer innovation in the market from others.
