Answer
toy begins to slide when the plane is at an angle of 36.0°
at this point the toy has just overcome the static friction


since toy begins to slide

now on comparing




as the body is moving at constant velocity acceleration will be zero
so now,


 
 

 
 
 
        
             
        
        
        
Answer:
Explanation:
F=ma
F=10N
A=v-u upon t
=1.5-0 upon 3
=0.5m per second squared
Then do force divided by. Accelaration and multiply by gravity.
 
        
             
        
        
        
To solve this problem we will apply the concepts related to the intensity included as the power transferred per unit area, where the area is the perpendicular plane in the direction of energy propagation.
Since the propagation occurs in an area of spherical figure we will have to


Replacing with the given power of the Bulb of 100W and the radius of 2.5m we have that


The relation between intensity I and 

Here,
 = Permeability constant
 = Permeability constant 
c = Speed of light 
Rearranging for the Maximum Energy and substituting we have then,




Finally the maximum magnetic field is given as the change in the Energy per light speed, that is,



Therefore the maximum value of the magnetic field is 
 
        
             
        
        
        
Newtons 1st law of motion states that the object will continue to move at its present speed and direction until an outside force acts upon it.
 
So unless the objects inside the car are restrained, they will continue moving at whatever speed the car is traveling at, even if the car is stopped by a crash.
