Answer:75m
Explanation: simple kinematics . xo=0 , vo=0
x=xo+vo*t +at*t/2 = 6*5*5/2 =75m
Answer:
Option A and E
Physical properties are not reversible
Answer:
(a) silver
(b) 4.94 x 10^-8 ohm
Explanation:
L = 2.4 m
diameter = 5.99 mm = 5.99 x 10^-3 m
Radius, r = diameter / 2 = 2.995 x 10^-3 m
R = 1.38 x 10^-3 ohm
(a) Let ρ be the resistivity of the material
R = ρ L / A
R A / L = ρ
ρ = (1.38 x 10^-3 x 3.14 x 2.995 x 10^-3 x 2.995 x 10^-3) / 2.4
ρ = 1.62 x 10^-8 ohm-m
The material is silver.
(b) t = 1.2 mm = 1.2 x 10^-3 m
Diameter = 2.24 cm = 0.0224 m
Radius, r = 0.0112 m
Resistance, R = ρ x t / A
R = 1.62 x 10^-8 x 1.2 x 10^-3 / (3.14 x 0.0112 x 0.0112)
R = 4.94 x 10^-8 ohm

Concepts and reason
The concept to solve this problem is that if a capacitor is connected in a RC circuit then it allows the flow of charge through circuit only till it gets fully charged. Once the capacitor is charged it will not allow any charge or current to flow.
Opposite is the case with inductor in the RL circuit. According to Faraday's law an inductor develops an emf to oppose the voltage applied but once the flux change stops then the inductor behaves just like a normal wire as if no inductor is there.
In attached figure, resistor is connected in series to the capacitor.
As we considered the voltage across the capacitor and the voltage across the source.
Voltage across a resistor In RC circuit.
Voltage across a resistor In RL circuit.
You are most likely to find a trench at a divergent boundary between two plates.

You don't have to but if you want to I recommend downloading this:

I'm currently in seventh grade and the assignments we are given in science is focused on earth and its layers. (because of schools closing ya know, online assignments and stuff, our teacher gave this helpful simulation sort of game)
Hope that helps! (it's basically a simulation of how plates form the way they do)
