there is no diagram, but i can try to help
Explanation:
strong winds bonding together (i.e hot and cold) help form the tornado, depending on the weather depends on how long it can go on, if more hot and cold are feeds into it, it will get faster and last longer. it is just like dust devils, it is wind and dirt mixing to make a tornado, the more wind and dirt the worst it will be
Answer: SI Unit is meters per second(m/s)
Explanation:
The three units of speed are:
1. meters per second(m/s)
2. kilometers per hour(km/hr)
3. miles per hour(mph)
SI Unit is meters per second(m/s)
Answer:
The correct option is;
B) The specific heat of ice is less than that of water.
Explanation:
Here we have
Let the amount of energy added to the ice at -10 C to raise the temperature to -5 C be X J
Let the amount of energy added to the water at 15 C to raise the temperature to 20 C be Y J
We know that the heat required, ΔQ to raise the temperature of a substance is given by
ΔQ = m·c·Δθ
Where:
m = Mass of the substance
c = Specific heat capacity
Δθ = Temperature change
Since the mass of the ice and the water are the same, so also is the change in temperature, (-5 - (-10) = 5 and 20 - 15 = 5) we have
for m₂·c₂·Δθ₂ > m₁·c₁·Δθ₁
Where:
m₁, c₁, Δθ₁, is for the ice and m₂, c₂, Δθ₂ is for the water and
m₁ = m₂
Δθ₁ = Δθ₂
Therefore,
c₂ > c₁ = c₁ < c₂
That is the specific heat capacity of the ice is lesser than the specific heat capacity of the water.
Answer:
Simple awnser Do it yourself I really would help but I have no clue! Sorry
Explanation:
Answer:
upthrust or BUOYANT FORCE =Vdg
volume=LWH
upthrust=(4cm×5cm×2cm)×1g/cm²×g
upthrust=40cm³×1g/cm³×g
upthrust=40gf or 0.04kg×10m/s²=0.4N
weight of the displaced liquid is upthrust.
so mass=40g or 0.04kg
upthrust=40gf or 0.4Nand mass of the displaced liquid=40g or 0.04kg
