Answer:
734.215N
Explanation:
First we calculate the angle that corresponds to a 5% slope using the Tan-1 function

then we use the component that corresponds to the direction parallel to the road, additionally we must multiply by the gravity value to find the weight(g=9.81m/s^2)
Wx=M*g*sen(2.86)=1500kg*9.81*sen(2.86)=734.215N
 
        
                    
             
        
        
        
Answer:
a
   
b
  
Explanation:
From the question we are told that 
   The initial position of the particle is  
   The initial  velocity of the particle is  
   The acceleration is   
    The time duration is  
Generally from kinematic equation 
     
=>  
=>  
Generally from kinematic equation
    
Here s is the distance covered by the particle, so
    
=>  
Generally the final position of the particle is  
     
=>   
=>   
 
        
             
        
        
        
Answer:
It looks like Surface 3
Explanation:
Because The Light is hitting it and then it bouncing back 
 
        
             
        
        
        
A
Increased metabolic rate due to exercise is helpful because the body uses more calories for everyday activities 
Explanation:
There is usually an increased demand for energy in the body with increased physical exercise. Therefore for the body to meet the energy demands, the metabolic rate of the body increases as it burns more glucose to produce more ATPs. More oxygen is required to efficiently produce many ATPs in the mitochondria which is why we pant when doing extraneous physical exercises.
