The rate of transfer of energy in a wave depends

The rate of transfer of energy in a wave depends

Can we do any work without transfer of energy ?

Statement-1 : in standing wave average rate of transfer of energy at any cross-section is zero. because Statement-2 : instantaneous rate of energy transfer at node is equal to zero.

Is there any transfer of energy while work is being done ?

Assertion : Work and heat are two equivalent form of energy Reason: Work is the transfer of mechanical energy irrespective of temperature difference, whereas heat is the transfer of thermal energy because of temperature difference only.
