Answer is in the question :)
Answer:
The average speed of the Earth in its orbit is 4.74 km/s.
Explanation:
Distance between the Earth and the Sun ,r= 149.60 million km = 
Considering the movement of Earth around the Sun follows circular path.
The circumference of circular path will be give by :

Time taken by Earth to complete revolution around earth ,T= 1 year
1 year = 365 days
1 year = 31,536,000 seconds
T = 31,536,000 seconds
Speed of the Earth around the Sun :S


The average speed of the Earth in its orbit is 4.74 km/s.
Answer:
The wave in the string travels with a speed of 528.1 m/s
Explanation:
Wave speed of sound waves in a string, v, is related to the Tension in the string, T, and the mass per unit length, μ, by the relation,
v = √(T/μ)
μ = 5.20 × 10⁻³ kg/m
T = 1450N
v = √(1450/0.0052) = 528.1 m/s
Hope this Helps!!!
Answer:

Explanation:
Given

Find x
Since the triangle is a 45-45-90 triangle, the following relationship exists
--- i.e. the other legs are equal
So, we have:

Divide both sides by 2

Take square roots of both sides

Simplify

B. solid
Explanation:
The solid state of matter is made up of particles that build repeating patterns. Solid is one of the four physical states of matter.
- Matter is described as anything that has weight and occupies space.
- The four states of matter are solid, liquid, gas and plasma.
- Solid particles are known to be closely packed and held together by very strong attractive forces.
- Solid like sodium chloride are said to be crystalline because they have crystals.
- Crystals are ordered atomic structures formed by repeating units of the fundamental molecular units.
- The repeating patterns of the crystals builds to form a solid.
- Other states of matter do not posses the repeating crystalline structure of solids.
