The correct statement is

Field lines should always be perpendicular to the equipotential lines.

we know that, along equipotential lines, work done in moving a charge is zero. Since work done is zero, the force on the charge must be perpendicular to the displacement. the electric force on a charge is parallel to the direction of electric field. hence the electric field must be perpendicular to the displacement or equipotential lines.

erastovalidia [21]

Answer:

Explained

Explanation:

Resistance R in a current flow through an object is given by

R= \frac{\rho L}{A}

ρ = resistivity of the material

L= length of the object

A=  area of cross section

clearly resistance is directly dependent on length of the object.This means greater the length larger will be resistance to current.

thermal resistance R_th is given by

R_{th} = \frac{L}{KA}

L= length of the object

A=  area of cross section

K = Conductivity of the material

thermal resistance is also is directly dependent on length of the object.This means greater the length larger will be resistance to current.

in a one dimensional collision, a 4kg object and 6 kg onject have initial velocity. calculate the magnitude of impulse
Greeley [361]

in a one dimensional collision, a 4kg object with 5ms^1 and 6 kg object with 2ms^1 have initial velocity, the magnitude of impulse is 12 , 18

given,

mass 1 = 4kg

mass 2 = 6kg

velocity 1 = 5ms^1

velocity 2 = 2ms^1

impulse 1 = 4*(5-2)

= 12

Impulse 2 = 6*(5-2)

= 18

vladimir2022 [97]

All metals except potassium and sodium, have a property known as malleability. Malleability is the quality of something that can be shaped into something else without breaking. So when aluminium and copper are hammered they will not break. Rather they will change shape and become thin or flat at the area where its hammered.

All Non- metals except diamond are brittle in nature, so when we hammer it , they will break down into pieces. So when ice and glass will be hammered they will shatter into pieces.
