Introducing vehicles that are built with lighter equipment, better gearing, improved aerodynamics, and better development in driving skills.
Answer:(c)
Explanation:
Charge particle posses a region of influence called a filed i.e. Electric field.
It is a region around the charged particle such that other charge particle experiences force due to this field. The nature of force is decided by the charge on the particle creating an electric field.
For a positive charge, electric field lines emerge out of it, and for a negative charge, it acts as radially inwards.
Answer:
1411.8 N/m
Explanation:
From Hooke's law;
F= Ke
Where
F= force on the spring
K= force constant
e = extension
But e= 8.50 × 10^-2m
F= weight = 12.0 kg × 10 = 120 N
K = F/e = 120/8.50 × 10^-2
K= 1411.8 N/m
I already said it but its reactivity
