Answer:
The number of charges is 1.25 × 10¹⁰
Explanation:
Current is the amount of charge flowing through a conductor per second. The formula for current (I) is given as:
I = Q/t
Where Q is the charge flowing in coulombs and t is the time taken in seconds.
Given that I = 2.0 nA = 2 × 10⁻⁹ A and t = 1 sec
I = Q / t
Q = It = 2 × 10⁻⁹ × 1 = 2 × 10⁻⁹ C
Since each charge = 1.6 x 10⁻¹⁹ C, therefore:
The number of charges = 2 × 10⁻⁹ C / 1.6 x 10⁻¹⁹ C = 1.25 × 10¹⁰
Answer:
Explanation:
For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:
which can also be rewritten as
In our case, we have:
is the initial pressure
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
Answer:
D. the ability to exercise for longer periods of time
Explanation:
For example, when someone does endurance training, they are stretching their body's ability to do a certain exercise for longer times as opposed to increasing strength.
Answer:
mechanical advantage!
Explanation:
The Mechanical advantage of a machine is the factor by which the machine changes the input force.
When a a machine multiplies an input force, that's called a mechanical advantage.
