. Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connecte
Umnica [9.8K]

Given :

Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.

To Find :

Will the heat produced in both the cases be equal.

Solution :

Heat released is given by :

H = i²Rt

Here, R is resistance and is given by :

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

So,

H = i^2\times \dfrac{\rho L}{A} t\\\\H = \dfrac{i^2\rho Lt}{A}

Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.

So, heat produced by Reem's wire is more than Nain one.

Hence, this is the required solution.

How Many Significant Digits are in 0.0217​
Bumek [7]

Answer:

<em>The number 0.0217 has 3 significant digits</em>

Explanation:

<u>Significant Digits </u>

These are digits that contribute to the significance of the number. Some rules apply to discard the non-significant digits like:

  • Leading zeros
  • Trailing zeros (with exceptions)

Our number is 0.0217 has two leading zeros before the 2 because they only occupy space to indicate the order of magnitude of the number. Only the 2,1,7 are significant digits, thus

The number 0.0217 has 3 significant digits

How would the atmosphere of earth differ if the earth was much larger
Juli2301 [7.4K]
If the earth just doubles its size in an instant, the oxygen present in the atmosphere could be much larger. Due to these, we could theorize that insects could grow much larger because the size of their body is heavily dependent on the maximum amount of oxygen present in the atmosphere. Air pressure also increases thus those aerial enthusiasts would enjoy their professions.

Explain why the reflection of light off ground glass changes from diffuse to specular if you spill water on it
Basile [38]
Because when you spill water on it, the reflection comes from the surface of the water, not the ground glass.
