Answer:

The electric field can cause the electrons to move around. Through this influence on electrons, we can give a net direction to the motion of the electrons. This is how we generate an electric current

A conductor is an object that conducts electricity through it, the mechanism of conduction of electricity is that, the electrons present in the atoms of the conductor are in rapid motion, and when we apply some potential difference across it by using cell, battery or anything, it causes those electrons to move in a particular direction and we know electrons have negative charge on it which , so the movement of charge ( electrons ) through a conductor causes electric current.

So, from above we conclude that conduction of electric current through a conductor is only possible due to free electrons present in the conductor's atoms.

A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away.

A)

It is a launch oblique, therefore the initial velocity in the vertical direction is zero. Space Hourly Equation in vertical, we have:

$S=S_{o}+v_{o}t+ \frac{at^2}{2} \\ 20= \frac{10t^2}{2} \\ t=2s$

Through Definition of Velocity, comes:

$\Delta v= \frac{\Delta S}{\Delta t} \\ v_x= \frac{36}{2} \\ \boxed {v_{x}=18m/s}$

B)

Using the Velocity Hourly Equation in vertical direction, we have:

$v_{y}=v_{y_{o}}+gt \\ v_{y}=10\times2 \\ \boxed {v_{y}=20m/s}$

The angle of impact is given by:

$cos(\theta) =\frac{v_{x}}{v_{y}} \\ cos(\theta) = \frac{18}{20} \\ cos(\theta) =0.9 \\ arccos(0.9)=\theta \\ \boxed {\theta \approx 25.84}$

The brachialis attaches to the forearm .035 m from the elbow at an angle of 32 deg. If the brachialis produces 750 N of force, w

jek_recluse [69]

Answer:

$XY=636N$

Explanation:

From the question we are told that:

Distance $d=0.35m$

Angle $\theta=32\textdegree$

Force $F=750N$

Generally the equation for magnitude of the stabilizing component of the brachialis force is mathematically given by

$XY=Fcos\theta$

$XY=750cos 32\textdegree$

$XY=636N$

How does Newton's second law apply to an "Egg Drop" experiment?

Black_prince [1.1K]

Because an object in rest stays in rest until an unequal force pushes it so gravity is pushing on the egg making it drop
