Answer:
The capacitor having less distance of separation has a stronger electric field.
Explanation:
The capacitors are identical and only difference between them is that one has twice the plate separation of the other. Therefore, capacitance of the given capacitors C1 and C2 is,
C1= Aε/d and C2=Aε/2d
The charges Q1 and Q2 on the capacitors of capacitance C1 and C2 respectively, is then given by the equation,
Q1=VC1
Q1=VAε/d
Q2=VC2
Q2=VAε/2d
Therefore, the surface charge density σ1 and σ2 for the capacitors is,
σ1=Q1/A
σ1=VAε/(d*A)
σ1=Vε/d
Similarly,
σ2=Q2/A
σ2=Vε/2d
The electric field between the plates is directly proportional to the surface charge density. And so electric field is inversely proportional to the distance of separation. Therefore the capacitor whose distance of separation is less has a stronger electric field.

Answer:
Resultant velocity will be equal to 6.10 m/sec
Explanation:
We have given a motorbike is traveling with 5 m/sec in east
And a current is flowing at a rate of 3.5 m /sec in north
We know that east and north is perpendicular to each other
So resultant velocity will be vector sum of both velocity
So resultant velocity 
So resultant velocity will be equal to 6.10 m/sec
Answer:
Mass and time are not vector quantities .
Explanation:
All the physical quantities can be classified into two major categories that is :
Scalar quantities
- They are those that describes only the magnitude and they are regarded as incomplete quantities as they don't provide complete information.
For example : Speed ,Mass, Time etc
Vector quantities
- They are complete quantities that can be described in magnitude as well as direction .
For example : Velocity ,gravity ,Acceleration etc
