They would melt because the heating of platinum that showed air was absorbed into its pores as it was heating, thus weakening the metal and causing it to melt at low temperatures
If you meant "What does the Earths system include?" here's your answer. The Earths system includes the atmosphere, which has all the planets air in it.
Answer:
F = 8 N
Explanation:
Given,
The mass of the smaller block, m = 20 Kg
The mass of the larger block, M = 96 Kg
The coefficient of the static friction, μ = 0.4
The static friction force acting on a body is the minimum horizontal force that is required to keep the smaller block from slipping down the larger block. It is given by the formula,
F = μ · η N
Where, η - normal force acting on the body
F = 0.5 x 20
= 8 N
Hence, the minimum horizontal force that is required to keep the smaller block from slipping down the larger block is, F = 8 N.
Answer:c=0.213 J/g/K
Explanation:
Given
sample mass
initial temperature of mineral
mass of water
Water initial temperature
Heat capacity of calorimeter =15.3 J/k
Final Temperature is 24.8
let c be the specific heat of mineral
Heat released by mineral sample=heat absorbed by calorimeter and water
