Explanation:

$\boxed{ \bold{ \underline{ \huge{ \boxed{ \sf{ohm's \: law}}}}}}$

The relation between current through a metallic conductor and potential difference across its ends was studied systematically by a German physicist , George Simon Ohm in 1826 AD . This relation is now known as Ohm's law. It states that the electric current passing through a conductor is directly proportional to the potential difference across its two ends at a constant physical condition [ Temperature , cross - sectional area , length , nature of material etc ]

Hope I helped!

2. Two trailers, X with mass 500 kg and Y with mass 2000 kg, are being pulled at the same

leva [86]

Answer:C

Explanation:

let the speed be v for both mass x and mass y

mass(x)=500kg

mass(y)=2000kg

Kinetic energy(mass(x))=(500 x v^2)/2

Kinetic energy(mass(x))=250v^2

Kinetic energy(mass(y))=(2000xv^2)/2

Kinetic energy(mass(y))=1000v^2

Ratio of kinetic energy y to x =1000v^2:250v^2

=1000v^2 / 250v^2

=4/1=4:1

Based on Newton's law of action-reaction, which arrow represents the force that the seat belt would exert on the man's body if h

Alenkasestr [34]

Answer:

c. Y

Explanation:

Newton's third law of motion states that action and reaction are equal and opposite. Hence for every action, there is an equal and opposite reaction.

Considering the system of forces shown in the image, W and Y are opposite forces. When the driver slams on the brakes, he will be pushed forward towards the windscreen. The force Y exerted by the seat belt keeps him on the drivers seat by moving him backwards towards the seat.

A 0.750-m-long pulse is travelling at a speed of 6.12 m/s in a spring. How long does it take the pulse to pass any point on the

Georgia [21]

Answer:

Explanation:

Speed = Distance/Time

Given

Speed = 6.12m/s

Distance = 0.750m

Substitute

Time - Distance//Speed

Time = 0.75/6.12

Time = 0.122secs

Hence it takes the pulse 0.122secs
