Two pieces of metal with exactly the same mass are placed on a surface in bright sunlight. the temperature of the 1st block increases by 3°c while the temperature of the 2nd increases by 8°c. if the specific heat of the 2nd block is 0.24 j/g-k, what is the specific heat of the 1st block?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
