Suppose a certain type of deciduous tree releases 7500 leaves on average each fall. If the average mass of each leaf is 1.7 g and a 120 acre forest has 206 of these trees per acre, how many kilograms of leaves are dropped on the forest floor ach fall?

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

heats surface water up

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
