Irina-Kira [14]

Answer:

The time constant τ = L/R represent the time requiered for the curent to get value of 63 % of its maximun value

Explanation:

In a circuit RL ( serie circuit with a resistor R and the inductor L ) when a voltage is applied the inductor will have a reaction, such reaction consist in the creation of an electromotive force which will prevent the current to get its maximun value. The time constant which in the case of an inductor is

τ = L/R , represent the time requiered for the crrent to be 63 % of its final value

An arrow is launched upward with an initial speed of 100 meters per second (m/s). The equations above describe the constant-acce

BigorU [14]

Answer:

510 m

Explanation:

The arrow is fired upward, so the motion of the arrow is a free fall motion, therefore we can find the maximum height by using the suvat equation

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

Here we have:

v = 0 (at the point of maximum height, the velocity of the arrow is zero)

u = 100 m/s (initial velocity)

$a=g=-9.8 m/s^2$ (acceleration of gravity, downward)

s = ? is the maximum height

Solving for s, we find the maximum height of the arrow:

$s=\frac{v^2-u^2}{2a}=\frac{0-100^2}{2(9.8)}=510 m$
