The ball's horizontal and vertical velocities at time
are


but the ball is thrown horizontally, so
. Its horizontal and vertical positions at time
are


The ball travels 22 m horizontally from where it was thrown, so

from which we find the time it takes for the ball to land on the ground is

When it lands,
and


Answer:
a
The magnetic field strength is 
Explanation:
From the question we are told that
The length line above the ground is 
The current of the line is 
The voltage of the line is 
Generally magnetic field strength is mathematically represented as

Where
is the permeability of free space 

![= (2.0*10^{-7})[\frac{200}{20} ]](https://tex.z-dn.net/?f=%3D%20%282.0%2A10%5E%7B-7%7D%29%5B%5Cfrac%7B200%7D%7B20%7D%20%5D)


Earths magnetic field is approximately given as 
So the percentage would be


%
Answer:
Explanation:
Using second degree taylor polynomials
let
be position function and set 
where S(0) is the initial position
Then
and 
we have
, 
so 
b.) yes
Well Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat. While <span>Heat energy (or thermal energy or simply heat) is defined as a form of energy which transfers among particles in a substance (or system) by means of kinetic energy of those particles. In other words, under kinetic theory, the heat is transferred by particles bouncing into each other.</span>
