Answer:
(a) Number of electrons per second strike the target is 3.125 x 10¹⁵.
(b) Charge that strikes the target in 0.750 s is 3.75 x 10⁻⁴ C .
Explanation:
(a) Let n be the number of electrons per second strike the target. We know that current (I) is given by the relation :
I = n x e
Here e is charge of electron.
Substitute 0.500 x 10⁻³ A for I and 1.6 x 10⁻¹⁹ C for e in the above equation.
0.500 x 10⁻³ = n x 1.6 x 10⁻¹⁹
n = 3.125 x 10¹⁵
(b) Let q be the charge that strikes the target. We know that :
q = I x t
Here I is current and t is time.
Substitute 0.500 x 10⁻³ A for I and 0.750 s for t in the above equation,
q = 0.500 x 10⁻³ x 0.750
q = 3.75 x 10⁻⁴ C
Answer:
A thin wire has more resistance than a thick wire
A short wire has less resistance than a long wire
A warm wire has more resistance than a cool wire
7 plus itself 4 times is 4 sevens aka 4*7
could alsto be 28
So, all Turkeys work to attract female Turkeys, but only dominant Turkeys benefit from it, and the less dominant Turkeys don't benefit at all from it. That means that they are exhibiting altruism:selfless behavior.
However, in practical terms their behaviour also helps them, as they are often related to the dominant males.
Answer:
The time is 1206 years.
Explanation:
Given that,
Distance = 27000 ly
Speed = 0.9990c
We need to calculate the time
Using formula of speed
Put the value into the formula
We need to calculate the time dilation the clock on the spaceship
Using formula of dilation time
The time convert in years
We know that,
So, the time is
Hence, The time is 1206 years.
