Answer:

Time constant of RC circuit is 0.105 seconds.

Explanation:

It is given that,

Resistance, R=50\ K\Omega=5\times 10^4\ \Omega

Capacitance, C=2.1\ \mu F=2.1\times 10^{-6}\ F

We need to find the expected time constant for this RC circuit. It can be calculated as :

\tau=R\times C

\tau=5\times 10^4\times 2.1\times 10^{-6}

\tau=0.105\ s

So, the time constant for this RC circuit is 0.105 seconds. Hence, this is the required solution.

A transverse standing wave is set up on a string that is held fixed at both ends. The amplitude of the standing wave at an antin
ZanzabumX [31]

Answer:

a) the maximum transverse speed of a point on the string at an antinode is 5.9899 m/s

b) the maximum transverse speed of a point on the string at x = 0.075 m is 4.2338 m/s

Explanation:

Given the data in the question;

as the equation of standing wave on a string is fixed at both ends

y = 2AsinKx cosωt

but k = 2π/λ and ω = 2πf

λ = 4 × 0.150 = 0.6 m

and f =  v/λ = 260 / 0.6 = 433.33 Hz

ω = 2πf = 2π × 433.33 = 2722.69

given that A = 2.20 mm = 2.2×10⁻³

so V_{max1} = A × ω

V_{max1} = 2.2×10⁻³ × 2722.69 m/s

V_{max1} =  5.9899 m/s

therefore, the maximum transverse speed of a point on the string at an antinode is 5.9899 m/s

b)

A' = 2AsinKx

= 2.20sin( 2π/0.6 ( 0.075) rad )

= 2.20 sin(  0.7853 rad ) mm

= 2.20 × 0.706825 mm

A' = 1.555 mm = 1.555×10⁻³

so

V_{max2} = A' × ω

V_{max2} = 1.555×10⁻³ × 2722.69

V_{max2} = 4.2338 m/s

Therefore, the maximum transverse speed of a point on the string at x = 0.075 m is 4.2338 m/s

A package is dropped from a hovering helicopter.
aivan3 [116]

Answer:

The height of the package when it was released was 1102.5 meters

Explanation:

A package is dropped from a hovering helicopter

Dropped means the initial velocity of the package is zero

The package takes 15 seconds to strike the ground

Ignore the air resistance

We need to know the height of the package when it was released

h=ut+\frac{1}{2}gt^{2}, where h is the height of the package

from the ground, u is the initial velocity, g is the acceleration of gravity

and t is the time

u = 0 , t = 15 seconds , g = 9.8 m/s²

h=(0)(15)+\frac{1}{2}(9.8)(15)^{2}

h=0+1102.5

h = 1102.5 meters

<em>The height of the package when it was released was 1102.5 meters</em>

A 69 g particle is moving to the left at 25 m/s . How much net work must be done on the particle to cause it to move to the righ
LekaFEV [45]

Answer:11.59 J

Explanation:

Given

mass of Particle m=69 gm

Initially Particle moves towards left v_1=25 m/s

Final velocity of Particle is towards Right v_2=31 m/s

According to Work Energy theorem

Work done by all the Forces=change in Kinetic Energy

Work done by Force=\frac{mv_2^2}{2}-\frac{mv_1^2}{2}

W=\frac{69\times 10^{-3}}{2}\left [ 31^-25^2\right ]

W=\frac{69\times 10^{-3}}{2}\left [ 961-625\right ]

W=11.59 J
