they are irreversible (you can't unburn paper) and affect the chemical composition of the object (when paper burns, it transforms the nearby oxygen into carbon dioxide using the carbon in the paper)
Answer:
0.114m
Explanation:
From the general expression for the radius of the proton's resulting orbit, we have

where q is is the charge of the proton 
m is the mass of the proton 
B is the magnetic field 
and v i the speed.
to determine the speed, we use the expression
Kinetic Energy=

where <em>V </em>is the voltage value i.e 1.0kv
and v is the speed
Hence, from simple rearrangement we have the speed v to be

if we substitute value, we have

carrying out careful arithmetic we arrive at
.
using the value for the speed in the expression for the radius of the orbit as stated earlier, we have


Answer:
increases
Explanation:
because as when the electimagnatics coul coul starts to increase the magnetic field also increases
Answer:
<h2>103 Joules</h2>
Explanation:
In this problem we are required to find the potential energy possessed by the television
Given data
mass of television m = 15 kg
height added above the ground, h= 1-0.3 = 0.7 m
acceleration due to gravity g = 9.81 m/s^2
apply the formula for potential energy we have
P.E= m*g*h
P.E = 15*9.81*0.7 = 103 Joules
