The place you get your hair cut has two nearly parallel mirrors 6.5 m apart. As you sit in the chair, your head is 2.0 m from th

ASHA 777 [7]

Answer:

13 m

Explanation:

It is given that :

I got a haircut sitting at a place having two parallel mirrors at a distance = 6.5 m apart

My head is at a distance of 2 m from the nearer mirror.

Now the light from the back of my head must go to (6.5 - 2) = 4.5 m to the back mirror.

Then it must go to 6.5 m to the front mirror and 2 m from the front mirror to my eyes.

So in order to see the back of my head, it will be = 6.5 + 2 + 4.5 = 13 m away.

a mass m at the end of a spring oscillates with a frequency of 0.78 hz . when an additional 730 g mass is added to m, the freque

ozzi

The value of mass m = 0.506kg

Initial frequency = 0.78Hz

additional mass = 730 g = 0.73kg

New frequency = 0.65 Hz

F = 1/2π $\sqrt{x\\}k/m$

0.78 = 1/2π $\sqrt{k/m}$

additional mass,

0.65 = 1/2π $\sqrt{k/m+0.65}$

1.44 = k/m / k/m+0.73

1.44 = m+0.73 / m

1.44m -m = 0.73

1.44m = 0.73

mass m = 0.506kg

a measurement used in physics to express the inertia, a quality that all matter has in common. Effectively, it is the resistance a body of matter offers to a change in its speed or position as a result of the application of a force. The change caused by an applied force is proportional to the mass of the body. The kilograms is the measure of mass in the International System of Units (SI). Its definition is based on the Planck constant, which is set at 6.62607015 1034 joule second. The unit of energy known as a joule is one kilogramme times one square metre per second. The kilogramme is determined by precise measurements of Planck's constant, while the second and metre are already defined in terms of other physical constants.

Dafna1 [17]

Answer:

(a) Tangential velocity will be 38.648 m/sec

(b) Acceleration will be $133.617m/sec^2$

Explanation:

We have given radius r = 11.2 m

Angular speed $\omega =0.550rev/sec=0.550\times 2\pi =3.454rad/sec$

(a) We have to find the tangential velocity

We know that tangential velocity is given by

$v_t=\omega r=3.454\times 11.2=38.684m/sec$

(b) We know that acceleration is given by

$a=\frac{v^2}{r}=\frac{38.684^2}{11.2}=133.617m/sec^2$

The distance between two parallel wires carrying currents of 10 A and 20 A is 10 cm. Determine the magnitude and direction of th

Marianna [84]

Explanation:

It is given that,

Current in wire 1, I₁ = 10 A

Current in wire 2, I₂ = 20 A

Distance between wires, d = 10 cm = 0.1 m

Force per unit length is given by :

$\dfrac{F}{l}=\dfrac{\mu_oI_1I_2}{2\pi r}$

$\dfrac{F}{l}=\dfrac{4\pi \times 10^{-7}\times 10\times 20}{2\pi \times 0.1}$

$\dfrac{F}{l}=0.0004\ N/m$

$\dfrac{F}{l}=4\times 10^{-4}\ N/m$

So, the magnetic force acting per unit length of the wires $4\times 10^{-4}\ N/m$ . Since, the current is in same direction. So, the force is attractive in nature.
