Answer:
0.004 m away from the film
Explanation:
u = Object distance
v = Image distance
f = Focal length = 50 mm

The image distance is 0.051 m
When u = 50 cm

The image distance is 0.055 m
The lens has moved 0.055-0.051 = 0.004 m away from the film
Arguably, far more dangerous. Whilst the initial stimulating effects of cocaine (it does this by blocking the reuptake of dopamine by the transporter proteins) giving the user a sense of self confidence and euphoria can result in rash and impulsive decisions leading to problems - the real issues with it lie in the tolerance that results.
your brain always wants to keep neurotransmitter levels stable, so when the dopamine levels skyrocket because their reuptake is blocked, the brain responds by reducing dopamine synthesis and the number of receptors, meaning without cocaine, your dopamine levels drop to below the norm.
Withdrawal symptoms are the complete opposite, leading to a dependency on the drug which causes far more damage than the effects of the drug itself.
Answer:
The height of the bag is 1.466 m.
Explanation:
Given that,
Acceleration of gravity 
Pressure = 14800 Pa
Specific gravity = 1.03
We need to calculate the density
Using formula of specific gravity


Where,
= density of solution
= density of water
Put the value in to the formula


We need to calculate the height
Using formula of pressure


Where, P = pressure
g = acceleration due to gravity
h = height
Put the value into the formula


Hence, The height of the bag is 1.466 m.
