Adults. 18years olds and older were affected because back then only 21 years olds and older could vote but the 26th amendment changed that
She can monitor her practice run times to see if they are decreasing.
Answer:
Factors determining the state of substances
* Inter molecular force : substances having strong intermolecular force will be solid and substance with weak inter molecular force will be gas.
* Nature of chemical bond:
Ionic compounds are generally solid in nature because of strong intermolecular force.
Polar covalent compounds may be solid or liquid
Non polar covalent compounds generally gas
* Electro negativity difference: greater the electronegativity difference, greater will be the intermolecular force.
In the owen, heat absorbed by two metals are different due to their specific heat(c -- Q=mct). the one that absorbed more heat, should cool down slower if their shapes are the same.
outside the owen, heat transferred to the air with related equation -- heat conductivity q=kAt/d. with the same amount of heat, block with better conductivity -- larger surface area(A), more thermal conductivity(k) and thiner(d), should have lower the temperature.
----- above is for you to understand where are the factors came from. not to answer as such.
in summary related factors are specific heat, thermal conductivity, surface area and thickness of the material. use this to explain such as 'one has larger surface area so it cool down faster'
Answer:
-0.375 m/s2
Explanation:
To find the acceleration due to gravity in this planet, we can use the Torricelli formula of UALM (uniformly accelerated linear motion):
V^2 = Vo^2 + 2*a*S
Where V is the final velocity, Vo is the inicial velocity, a is the acceleration and S is the total displacement.
With V = 3, Vo = 0 and S = -12, we have:
3^2 = 0^2 - 2*a*12
24a = -9
a = -9/24 = -0.375 m/s2
