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 :
So,
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.
Some of the benefits are increased heart muscles, increase in blood flow, and reduced body fat
Answer:
C
Explanation:
Because...
A= Incideant ray
B= Angle of inciderance
<u>C= angle of reflection</u>
D= reflection ray
Answer:
Both balls have the same speed.
Explanation:
Janelle throws the two balls from the same height, with the same speed. Both balls will have the same potential and kinetic energy. Energy must be conserved. When the balls pass Michael, again they must have the same potential and kinetic energy.
Sound or Soundwaves travel through mediums by vibrating molecules. Sound waves mediums can often travel through gas, liquid, and solid. Compared to liquids, solids seem to travel better because the molecules that make up the matter are packed tightly.
