Answer:
Q must be placed at 0.53 L
Explanation:
Given  data:
q_1 = 4.0 μC , q_2 = 3.0μC
Distance between charge is L
third charge q be placed at  distance x cm from q1
The force by charge q_1 due to q is

 ----1
                  ----1
The force by charge q_2 due to q is

 --2
                   --2
we know that net electric force is equal to zero
F_1 = F_2





x = 0.53 L
Q must be placed at 0.53 L
 
        
             
        
        
        
Answer:
The smallest possibility is 0.01E-22kgm/s
Explanation:
Using 
Momentum= h/4πx
 = 6.6x 10^-34Js/ 4(3.142* 50*10-12m)
= 0.01*10^-22kgm/s
 
        
             
        
        
        
Although they're all 'close', none of the planets orbits in the same plane as any other planet.  They're all in slightly different planes.
The farthest out compared to all the others is Pluto, with an orbit inclined about 17 degrees compared to the ecliptic plane (Earth's orbit).  But Pluto is officially not a planet, so I don't think it's a good answer.
The next greatest inclination compared to Earth's orbit is <em>Mercury</em>.  That one is about 7 degrees.
The other six planets are all in different orbital planes inclined less than 7 degrees compared to Earth's orbit.
 
 
        
             
        
        
        
Answer:
temperature measures heat - the unit is Celsius - and it is measured with a thermometer. 
length is measuring how long, tall, or wide something is  - the base unit it metres - and it is measured with a ruler or a metre stick
volume is measuring the quantity of a three dimensional space - the unit is cubic centimetre - you find volume by taking the measurements with a ruler 
mass is measuring how much space something takes up/ weight - unit is the gram - you use a scale
 
        
             
        
        
        
Answer:
Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Newton's third law states that if an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
