suppose the mass of a metal object be m and its specific heat capacity be s, and, H joules of heat is required to raise its temperature by t degrees Celsius
Than H is given by relation,
Now if this object is cut in two half's, than mass of half part will also be half <em>i.e. </em>M/2
So heat required to heat the half part will be
Hence, the heat required to raise the half object to a specific temperature will also become half.
Answer:
The velocity is
Explanation:
From the question we are told that
The first distance is
The first speed is
The second distance is
The second speed is
Generally the time taken for first distance is
The time taken for second distance is
The total time is mathematically represented as
=>
=>
Generally the constant velocity that would let her finish at the same time is mathematically represented as
=>
=>
