Answer:
8m/s
Explanation:
Average Speed = distance / time = 400/50 = 8m/s

Answer:
more light enters and disturbs the formation of the image.
Answer:
20 m/s
Explanation:
Recall that one of the equations of motions can be written:
v = u + at, (also see attached for reference)
Where,
v = final speed (we are asked to find this)
u = initial speed = 0 (because it starts from rest)
t = time taken = 5s
We simply substitute the given values into the equation:
v = u + at
v = 0 + (4)(5)
v = 20 m/s
Answer:
The pressure is 
The temperature is 
Explanation:
Generally Gibbs free energy is mathematically represented as

Where E is the enthalpy
PV is the pressure volume energy (i.e PV energy)
S is the entropy
T is the temperature
For stability to occur the Gibbs free energy must be equal to zero
Considering Diamond
So at temperature of T = 300 K

making P the subject

Now substituting 300 K for T , 2900 J for E ,
for V and
for S


The negative sign signifies the direction of the pressure
Given that 
making T the subject

Substituting into the equation
