v_f=0
(1)
having into account that the total time spent in air till the cap came to her hands is Ttotal=2*t
where t is the time which the cap spent to reach the heighest point or the maximun height. so;
Ttotal=2second
t=1sec
we then replace t into the equation(1);
this is the initial velocity with which the cap was thrown
Income inequality is bad enough, but wealth inequality is way worse. many people today are not equal due to there wealth. more wealthier people have better things obviously,and they also get more stuff in general. therefore, the wealth gap is way bigger because there are all sorts of "rich" "poor" and middle classman in the world today
Answer:
Inductor.
Explanation:
it is given that, the voltage across the device leads the voltage across a resistor at 500 Hz. The device that has unknown circuitry can be a inductor. For LC circuit, the voltage across the inductor leads the voltage across resistor. So, the device can be a inductor.
Unlike charges attracting each other
Hi there!
We can use the following equation to calculate the magnetic field inside of a solenoid:
B = Magnetic Field Strength (T)
n = number of loops PER LENGTH
i = current through solenoid (A)
μ₀ = Permeability of free space (4π × 10⁻⁷ Tm/A)
First, we can solve for 'n' given 'N' (total # of loops) and L (length of solenoid).
Now, we can calculate the magnetic field:
