11m if you add 6+5 you get 11 but of course you need the “m” in the mix so 11m but correct me if I’m wrong.

Is mass is 88.2 and height of distance is 25m, how do you find speed?

Natasha_Volkova [10]

Answer:

The velocity will be v = 22.1[m/s]

Explanation:

We can solve this problem by using the principle of energy conservation, where potential energy is converted to kinetic energy. For this problem we will take the point with maximum potential energy when the body is 25 [m] high. By the time the height is zero, the potential energy will have been transformed into kinetic energy, and we can find the velocity of the body.

$Ep = m*g*h\\where:\\m = mass = 88.2[kg]\\h = elevation = 25[m]\\g = gravity = 9.81 [m/s^2]\\Ep = 88.2*25*9.81 = 21631.05[J]\\$

Now we know that the energy will be transformed.

$Ek=Ep\\Ek=0.5*m*v^{2} \\where:\\v=velocity [m/s]\\v=\sqrt{\frac{Ek}{0.5*m} } \\v=\sqrt{\frac{21631.05}{0.5*88.2} } \\v=22.14[m/s]$

You set a small eraser at a distance of 0.27 m from the center of a turntable you find in the attic and establish that when the

Licemer1 [7]

Answer with Explanation:

We are given that

Distance,r=0.27 m

Tangential speed=v=0.49 m/s

a.Angular speed , $\omega=\frac{v}{r}$

Using the formula

$\omega=\frac{0.49}{0.27}=1.8 rad/s$

$\omega=\frac{2\pi}{T}$

$T=\frac{2\pi}{\omega}$

Time period, $T=\frac{2\pi}{1.8}=3.49 s$

b.Amplitude,A=Distance of small eraser from the center of a turnable =0.27 m

c.Maximum speed, $V_{max}=0.49 m/s$

d.Maximum acceleration= $a=r\omega^2=0.27(1.8)^2=0.87 m/s^2$

morpeh [17]

Answer:

Force, $F=8.23\times 10^{-8}\ N$

Explanation:

It is given that,

Each ion in Na⁺ and Cl⁻ has a charge of, $q=1.6\times 10^{-19}\ C$

Distance between two ions, $d=5.29\times 10^{-11}\ m$

We need to find the electrostatic force. It is given by :

$F=k\dfrac{q_1q_2}{d^2}$

$F=9\times 10^9\times \dfrac{(1.6\times 10^{-19})^2}{(5.29\times 10^{-11})^2}$

$F=8.23\times 10^{-8}\ N$

So, the magnitude of electrostatic force between them is $F=8.23\times 10^{-8}\ N$ . Hence, this is the required solution.

Ask Your Teacher A beam of light is incident from air on the surface of a liquid. If the angle of incidence is 33.5° and the ang

Oduvanchick [21]

Answer:

The critical angle for the liquid when surrounded by air is 30 degrees.

Explanation:

Given that,

The angle of incidence is 33.5° and the angle of refraction is 19.3°. Firstly, we can find the refractive index of the liquid. It can be calculated using Snell's law as :

$n=\dfrac{\sin i}{\sin r}\\\\n=\dfrac{\sin (33.5)}{\sin (19.3)}\\\\n=2$

The critical angle is given by :

$\theta_c=\sin^{-1}(\dfrac{n_1}{n_2})$

Here, $n_1$ is refractive index of air and $n_2$ is refractive index of liquid.

$\theta_c=\sin^{-1}(\dfrac{1}{2})\\\\\theta_c=30^{\circ}$

So, the critical angle for the liquid when surrounded by air is 30 degrees.
