When energy from the sun hits the air above land, the air warms up and rises. Along a
coastline, cooler air above the ocean flows
toward the land and replaces this rising air.
Which best describes these processes?
(A) conduction and convection
B conduction, convection, and radiation
radiation and conduction
D radiation and convection

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

the body's situation won't change the forces are equal opposit and on the same body

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
