Calculate the average speed of the moon around the earth. The moon has a period of revolution of 27.3 days and an average distan
klio [65]
<h2>The average speed of the moon around the earth is 1021.74 m/s</h2>

Explanation:

Radius of moon around earth, r = 3.84 × 10⁸ m

Circumference of orbit = 2πr = 2 x 3.14 x 3.84 × 10⁸

Circumference of orbit = 2.41 x 10⁹ m

Time taken, t = 27.3 days = 27.3 x 24 x 60 x 60 = 2358720 seconds

We have

       Circumference of orbit = Speed of moon x Time taken

        2.41 x 10⁹ = Speed of moon x 2358720

       Speed of moon = 1021.74 m/s

The average speed of the moon around the earth is 1021.74 m/s

A 33.0 g iron rod, initially at 22.7 ∘c, is submerged into an unknown mass of water at 63.3 ∘c, in an insulated container. the f
professor190 [17]
When the iron and the water reach thermal equilibrium, they have same temperature, T=58.5^{\circ}C.
We can consider this as an isolated system, so the heat released by the water is equal to the heat absorbed by the iron.

The hear released by the water is:
Q_w =m_w C_{sw} \Delta T_w
where m_w is the water mass, C_{sw}=4.186 J/(g^{\circ}C) is the specific heat of the water, and \Delta T_w = 63.6^{\circ}-58.5^{\circ}=5.1^{\circ}C is the variation of temperature of the water.

Similarly, the heat absorbed by the iron is:
Q_i = m_i C_{si} \Delta T_i
where m_i = 33.0 g is the iron mass, C_{si}=0.444 J/(g^{\circ}C) is the iron specific heat, and \Delta T_i = 58.5^{\circ}-22.7^{\circ}=35.8^{\circ}C is the variation of temperature of the iron.

Writing Q_w=Q_i and replacing the numbers, we can solve to find mw, the mass of the water:
m_w= \frac{m_i C_{si} \Delta T_i}{C_{sw} \Delta T_w} =24.6 g

How can seismographs be used to predict hurricane intensity?
nikdorinn [45]

Answer: The earth is a noisy place. Seismometers, which measure ground movements to detect earthquakes, volcanic eruptions, and manmade explosives, are constantly recording smaller vibrations caused by ocean waves, rushing rivers, and industrial activity.
