Answer: 120N
Explanation:
Given variables are:
force needed = ?
mass of object = 60 kg
acceleration = 2.0 m/s²
Since the magnitude of force depends on the mass of the object and the acceleration by which it moves.
i.e Force = mass x acceleration
Force = 60 kg x 2.0 m/s²
Force = 120 N
Thus, 120 Newton of force is needed to make 60 kg object accelerate at a rate of 2.0 m/s²
Answer: I believe it’s element symbols
Explanation: I hope we both get it right
B.
I think this is right.
If it is not I apologize
Answer: c. ΔH˚ is positive and ΔS˚ is positive
Explanation:
According to Gibb's equation:
= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Thus for 
Case :
>
when 
both have positive values.
Reaction is spontaneous only at at high temperatures.
