The Speed of a moving vehicle can be measured. The average time it will taken too cover both distance are shown below;
 
The average travel times traveled are :
0.25 meters = 2.23 seconds
0.50 meters = 3.13 seconds
Therefore, the Average travel time to cover 0.25 meters is:
(Trial 1 + Trial 2 + Trial 3) ÷ 3
(2.24 + 2.21 + 2.23) / 3 = 6.68 = 2.2266 = 2.23 seconds ( approximated to 2 decimal places).
Therefore, the Average travel time to cover 0.50 meters is 
(Trial 1 + Trial 2 + Trial 3) ÷ 3
(3.16 + 3.08 + 3.15) / 3 = 9.39 ÷ 3 = 3.13 seconds
Conclusively, the average time taken to cover 0.25 and 0.50 meters is said to be 2.23 and 3.13 seconds for the both..

This question is incomplete, the complete question is;
A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.0 cm wide and 5.00 m long. Between the sheets is a mica strip of the same width and length that is 0.0225 mm thick. What is the maximum charge?
(The dielectric constant of mica is 5.4, and its dielectric strength is 1.00×10⁸ V/m)
 
Answer: the maximum charge q is 716.85 μF
Explanation:
Given data;
with = 3.0 cm = 0.03
breathe = 5.0 m
Area = 0.03 × 5 = 0.15 m²
dielectric strength E = 1.00 × 10⁸
∈₀ = 8.85 × 10⁻¹²
constant K = 5.4
maximum charge = ?
the capacitor C = KA∈₀ / d 
q = cv so c = q/v
now
q/v = KA∈₀ / d 
q =  vKA∈₀/d = EKA∈₀
we substitute
q = (1.00 × 10⁸) × 5.4 × 0.15 ×  8.85 × 10⁻¹²    
q = 716.85 × 10⁻⁶ F
q = 716.85 μF
the maximum charge q is 716.85 μF
 
        
             
        
        
        
Answer:
The correct answers are the proportionality of the fields concerning distance, vector fields, and forces at a distance.
Explanation:
The similarities between magnetic fields and electric fields are that electric fields are produced by two charges that can be positive and negative. Magnetic fields are associated with two magnetic poles, although they are also produced by moving charges. Both fields are inversely proportional to the square of the distance between the sources, both fields are vectorial and both act by distant forces.

Speed of the tip of the minute hand=V=0.0244 cm/s
Explanation:
The angular velocity of the minute hand is given by
 
 T= time period of the minute hand=60 min=3600 s
so ω= 2 π/3600 rad/s
Now linear velocity v= r ω
r= radius of minute hand=14 cm
so v= 14 (2 π/3600)
V=0.0244 cm/s
