Answer:
At low pressure-  
At high pressure-  
Explanation:
Initial speed,  
Final speed,  
Net horizontal force due to rolling friction  mg where m is mass, g is acceleration due to gravity,
 mg where m is mass, g is acceleration due to gravity,  is coefficient of rolling friction
 is coefficient of rolling friction
From kinematic relation,  
For each tire,
 
Making  the subject
 the subject
 
Under low pressure of 40 Psi, d=18 m
 
Therefore,  
At a pressure of 105 Psi, d=93.7
 
Therefore,  
 
        
             
        
        
        
Answer:
52.49 Kg
Explanation:
Let m1 and v1 denote your mass and velocity respectively
Let m2 and v2 denote your friends mass and velocity respectively
Kinetic energy is given by
 
  
Since your kinetic energies are the same hence
 
 and making m2 the subject then
 and making m2 the subject then  
 
Since v2 is v1+0.28v1=1.28v1
Substituting m1 for 86 Kg

Answer:
Magnitude of the magnetic field inside the solenoid near its centre is 1.293 x 10⁻³ T
Explanation:
Given;
number of turns of solenoid, N = 269 turn
length of the solenoid, L = 102 cm = 1.02 m
radius of the solenoid, r = 2.3 cm = 0.023 m
current in the solenoid, I = 3.9 A
Magnitude of the magnetic field inside the solenoid near its centre is calculated as;

Where;
μ₀ is permeability of free space = 4π x 10⁻⁷ m/A

Therefore, magnitude of the magnetic field inside the solenoid near its centre is 1.293 x 10⁻³ T
