Kirsin is learning about the outer planets what else would she know about a planet that is the second largest gas giant and has
the largest rings?
1 answer:
Answer: <u>Saturn is the second largest gas giant and has the largest rings.</u>
Explanation:
- Saturn is the 2nd largest planet in the solar system after Jupiter.
- It is the 6th planet from the Sun and located between Jupiter and Uranus.
- Saturn was named after "Saturnus", the roman god of agriculture.
- Saturn orbital period to move around sun is 29 and half earth years
- Saturn is called gas giant because it is not made of any solid material but light gases (hydrogen and helium).
- Saturn has largest rings. These are made up of pieces of ice, rocks and dust.

Answer:
=118.8 K= 154.2°C
Explanation:
COP_max of carnot heat pump=
where T_H and T_C are temperatures of hot and cold reservoirs
Also COP=
in the question
⇒
heat is added directly to be as efficient as via heat pump
and T_H= 24° C= 297 K
on calculating the above equation we get
=118.8 K
the outdoor temperature for efficient addition of heat to interior of home
=118.8 K= 154.2°C
Answer:
The extension of the wire is 0.362 mm.
Explanation:
Given;
mass of the object, m = 4.0 kg
length of the aluminum wire, L = 2.0 m
diameter of the wire, d = 2.0 mm
radius of the wire, r = d/2 = 1.0 mm = 0.001 m
The area of the wire is given by;
A = πr²
A = π(0.001)² = 3.142 x 10⁻⁶ m²
The downward force of the object on the wire is given by;
F = mg
F = 4 x 9.8 = 39.2 N
The Young's modulus of aluminum is given by;
Where;
Young's modulus of elasticity of aluminum = 69 x 10⁹ N/m²
Therefore, the extension of the wire is 0.362 mm.
