Answer:
(D) F/2
Explanation:
Since the circular section is unbanked, the centripedal acceleration acting on each of the cars is


Therefore the centripetal force on each car


Since  this means the friction force required to keep the large car on the road is only half of the friction force required to keep the small car on road
 this means the friction force required to keep the large car on the road is only half of the friction force required to keep the small car on road
So (D) F/2 is the correct answer
 
        
             
        
        
        
Answer:
Gravity. 
Explanation:
The force that controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped in clusters is called gravity.
This ultimately implies that, gravity is considered to be a universal force of attraction that acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, weight is given by the formula;
 
 
Where;
m is the mass of an object.
g is acceleration due to gravity.
 
        
             
        
        
        
Mass/density= volume so it will be 360/0.9 which equals to 400 and if you want to find mass you just need to multiple volume•density

Generally the speed of the transverse cable is mathematically represented as 
            
substituting values 
          
         
            
 
        
             
        
        
        
Answer:
10.032 N. 
Explanation:
From the question given above, the following data were obtainedb
Mass (m) = 2.5 Kg
Final length = 10.0 cm
Original length = 21.4 cm
Spring constant (K) = 88 N/m
Force (N) =?
Next, we shall determine the compression of the spring. This can be obtained as follow:
Final length = 10.0 cm
Original length = 21.4 cm
Compression (e) =? 
e = Original length – final length 
e = 21.4 – 10
e = 11.4 cm
Next, we shall convert 11.4 cm to m. This can be obtained as follow:
100 cm = 1 m
Therefore, 
11.4cm = 11.4 cm × 1 m / 100 cm
10 cm = 0.114 m
Finally, we shall determine the force. This can be obtained as illustrated below:
Compression (e) = 0.114 m
Spring constant (K) = 88 N/m
Force (N) =?
F = Ke
F = 88 × 0.114
F = 10.032 N
Thus, the force in the spring is 10.032 N
