Answer:
Polar Bears
Arctic Foxes
Seals
Penguins
They all live in the cold, so they all must live in the Arctic Tundra ;)
Answer:
3.05 ×10³ Kg/m³
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Density = 3.05 g/cm³
Density in Kg/m³ = ?
Solution:
In order to convert the g/cm³ to Kg/m³ we will multiply the value with 1000.
3.05 g/cm³ × 1000 Kg/m³ / 1 g/cm³
3050 Kg/m³
In scientific notation:
3.05 ×10³ Kg/m³
Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
Internal energy= (- heat evolved by the system) + Work done by the system
ΔU = -Q+W
W = - PΔV
P= pressure
ΔV =difference in volume
Given,
V1 = 10 L
V2 = 90 L
∴ΔV = V2-V1 = 90-10 = 80 L
P = 1 atm
∴W = - ( 1× 80)
= -80 kJ
Heat evolved by the system = 90 kJ
∴Δ U= - 90 kJ - 80 kJ
= - 170 kJ
Thus, Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
NOTE : here work done by the system is considered negative and also heat evolved by the system is taken -Ve.

The appropriate response is a voluntary exchange. It is the demonstration of purchasers and merchants openly and energetically captivating in market exchanges. Additionally, exchanges are made such that both the purchaser and the dealer are in an ideal situation after the trade than before it happened.
Shows that water is a compound...
made up of 2 hydrogen atoms and 1 oxygen atom...=H2O...
decomposition of water is by electrolysis which splits the compound!
hope this helps!
