A 1.5m wire carries a 8A current when a potential difference of 67v is applied what is the resistance of the wire

Drupady [299]3 years ago

Data is inappropriate

  here, we need gauge of the wire i.e., diameter of the wire, so that we calculate the resistance by using the formula

                              R  = ρl/A            

            where R= resistance ; Ω

                       l = length of wire ; m

                       A = area of wire ; m²

                       ρ = resistivity ; Ω-m

But in general ohms law is

                    V = I R

                    R = V/I ;

but here we also calculate "R" from length of wire in which the current is flowing.

I hope it is helpful to you.

Travka [436]

Answer:

F  = 183.153 N

Explanation:

given,

mass of the toothpick = 0.12 g = 0.00012 kg  

initial velocity = 227 m/s    

final velocity = 0 m/s      

penetration depth = 16 mm = 0.016 m        

using the equation of motion        

v² - u² = 2 a s                            

0 - u² = 2 a s                                      

- 221² = 2 × a × 0.016      

a = 1526281.25 m/s²            

Force is equal to            

F = m a

  = 0.00012 × 1526281.25

F  = 183.153 N

The greater the mass is in an object, the higher resistance to a change in movement the object will have. Please select the best
Fofino [41]
This statement is true. The greater the mass is in an object, it is indeed the higher resistance to a change in movement the object will have. That only mean that the mass of an object and its resistance to change of movement is directly proportional.

Dmitrij [34]

Answer:

Backwash effect

Explanation:

Your friend moved along the shore due to ; The swash effect and the Backwash effect

Swash effect is caused by the upsurge of water up along the slopping front of the beach  and this same upsurge in water moves back into the beach in what is known as the backwash effect hence the movement of your friend form where they were in the surf zone to another position still within the surface zone is caused by the BACKWASH EFFECT
