Answer:
120 mA
Explanation:
The relationship between voltage, current and resistance in a circuit is given by Ohm's law
where
I is the current
V is the voltage
R is the resistance
In this problem, we have an initial current of
I = 60 mA
Then the voltage is doubled:
V' = 2 V
while the resistance is kept the same:
R' = R
So the new current is
so, the current has doubled. Since I = 60 mA, the new current is
Answer:
E = 2.5 x 10⁻¹⁴ J
Explanation:
given,
diameter = 1.33 x 10⁻¹⁴ m
mass = 6.64 x 10⁻²⁷ kg
wavelength is equal to diameter
de broglie wavelength equal to diameter
v = 7.5 x 10⁶ m/s
Kinetic energy is equal to
E = 2.5 x 10⁻¹⁴ J
Answer:
Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

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.
Li2O is the molecular formula for lithium oxide.
