Answer:

The distance is 1.026 m.

Explanation:

mass of rod, M = 1.23 kg

Length, L = 1.25 m

mass, m = 10 kg

Time period, T = 2 s

Let the distance is d.

The formula of the time period is given by

$T = 2\pi\sqrt\frac{\frac{1}{3}ML^2+md^2}{(M +m)g}\\\\2\times 2 = 4\pi^2\times \frac{\frac{1}{3}\times1.23\times1.25\times 1.25+ 10d^2}{(1.23 + 10)\times9.8}\\\\11.16 = 0.64 + 10d^2\\\\d= 1.026 m$

romanna [79]

Answer:

a) t = 0.25 s, b) x = 0.075 m

Explanation:

a) For this exercise we will use kinematic relationships in one dimension

v = v₀ + a t

in the problem they indicate the initial velocity v₀ = 0.15 m / s, the final velocity v = 0.45 m / s and the acceleration of the squid a = 1.2 m / s²

t = $\frac{v -v_o}{a}$

we calculate

t = $\frac{0.45 - 0.15}{1.2}$

t = 0.25 s

b) We can also find the distance traveled during this acceleration

v² = v₀² + 2a x

x = $\frac{v^2 -v_o^2 }{2a}$

let's calculate

x = $\frac{0.45^2 - 0.15^2 }{2 \ 1.2}$

x = 0.075 m

How does an electroscope detect negative static electricity

MA_775_DIABLO [31]

<span> An electroscope that might have a static charge is tested on a metal surface. From there, the charges move to the metal and straight to the foil leaves. If they repel, or move away from each other, that means they have identical charges. This applies for both positive and negative static electricity.
