Density review
A B
What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm3? d = .85 g/cm3
A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? (volume = L x W x H) d = 1.11 gm/cm3
It can’t be b because that will increase the dissolving rate
<h3>Longitudinal Waves:</h3>
- Longitudinal waves are waves in which particles moves in the direction parallel to the direction of wave.
- Longitudinal wave are one directional waves.
- Sound waves and tension force applied on spring are examples of longitudinal waves.
<h3>Transverse Waves:</h3>
- Transverse waves in which particles move perpendicular to the direction of wave propagation.
- Transverse wave are two directional waves.
- Ripples formed on water and all electromagnetic waves are examples of transverse waves.
Answer:
The height of the Everest mountain is, x = 8514.087 m
Explanation:
Given data,
The gravitational field strength at the top of mount Everest, gₓ = 9.772 m/s²
The formula for gravitational field strength is,
<em> gₓ = GM/(R+x)²</em>
Where, x is the height from the surface of the Earth
Therefore,
(R+x)² = GM/gₓ
x = √(GM/gₓ) - R
Substituting the values,
x = √(6.67408 x 10⁻¹¹ X 5.972 x 10²⁴ / 9.772) - 6.378 x 10⁶
x = 8514.087 m
Therefore, the height of the Everest mountain is, x = 8514.087 m
