Answer:

Friction

Explanation:

Friction is rubbing two objects together. When this happens electrons from one object goes to the other. When one object loses electrons, it will have more protons, so it will be positively charged. When one object gains electrons it becomes negatively charged.

This is what happens when you rub a rubber balloon on your hair, or even on the wall. Because one will be negatively charged and the other positive, the objects then attract each other and they stick together, like what happens when you rub the balloon on your hair, you hair will stick to the balloon, or vice-versa.

The force applied to lift the crate is 171 N

Explanation:

The lever works on the principle of equilibrium of moments, so we can write:

$F_i d_i = F_o d_o$

where

$F_i$ is the force in input

$d_i$ is the arm of the input force

$F_o$ is the output force

$d_o$ is the arm of the output force

For the lever in this problem, we have:

$d_i = 0.25 m$

$d_o = 0.19 m$

$F_i = 130 N$ (force applied)

Solving the equation for $F_o$ , we find the force applied to lift the crate:

$F_o = \frac{F_i d_i}{d_o}=\frac{(130)(0.25)}{0.19}=171 N$

Which statement describes the process of subduction? Convection currents pull a plate into the mantle. One plate slides beneath

mixas84 [53]

Answer:

Subduction is the geological process in which one plate moves under another due to gravitational pull. The regions where this process occurs called subduction zones.

A subduction is a tectonic plate which is made up of crust and upper layer of mantle. These two layers are called as lithosphere.

Example: South America, central America and cascade volcanoes. In which the oceanic plate descends beneath a continental plate.

What is the intensity in W/m2 of a laser beam used to burn away cancerous tissue that, when 85.0% absorbed, puts 470 J of energy

Advocard [28]

Answer:

26036485.6433 W/m²

Explanation:

E= Energy = 470 J

t = Time = 4 seconds

d = Diameter = 2.6 mm

Power is given by

$P=\dfrac{E}{t}$

Intensity is given by

$I=\dfrac{P}{\pi r^2}\\\Rightarrow 0.85I=\dfrac{E}{t\dfrac{\pi}{4} d^2}\\\Rightarrow I=\dfrac{470}{0.85\times 4\times \dfrac{\pi}{4}\times (2.6\times 10^{-3})^2}\\\Rightarrow I=26036485.6433\ W/m^2$

The intensity of the laser beam is 26036485.6433 W/m²
