Answer:
514 cal
Explanation:
In order to calculate the lost heat by the amount of water you first take into account the following formula:
(1)
Q: heat lost by the amount of water = ?
m: mass of the water
c: specific heat of water = 1cal/g°C
T2: final temperature of water = 11°C
T1: initial temperature = 12°C
The amount of water is calculated by using the information about the density of water (1g/ml):
Then, you replace the values of all parameters in the equation (1):
The amount of water losses a heat of 514 cal
It’s very big and very small numbers
Answer:
456
Explanation:

this isn't really much information but hope this helps !: )
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
