Ionic is where the bonding of elements attract opposites
*may be egg shaped
*has no new stars being formed
*has almost no gas or dust between stars
I literally just took notes on elliptical galaxies a week ago wow
Assuming the gas behaves ideally,
PV/T = constant. P will also be constant in this giving us:
V₁/T₁ = V₂/T₂
40/320 = 20/T₂
T₂ = 160 K
The answer is A.
Answer:
The specific heat for the metal is 0.466 J/g°C.
Explanation:
Given,
Q = 1120 Joules
mass = 12 grams
T₁ = 100°C
T₂ = 300°C
The specific heat for the metal can be calculated by using the formula
Q = (mass) (ΔT) (Cp)
ΔT = T₂ - T₁ = 300°C - 100°C = 200°C
Substituting values,
1120 = (12)(200)(Cp)
Cp = 0.466 J/g°C.
Therefore, specific heat of the metal is 0.466 J/g°C.
Answer:
Electric force, 
Explanation:
It is given that,
Charge on an electron is 
Electric field, 
We need to find the magnitude of the electric force on this electron due to this field. The electric force is given by :
So, the electric force is 
.
