Asample of 500 g of an isotope decays to another isotope according to the function upper a (t )equals 500 e superscript negative 0.044 ta(t)=500e−0.044t, where t is the time in years. (a) how much of the initial sample will be left in the sample after 2020 years? (b) how long will it take the initial sample to decay to half of its original amount?

c) up

hope this

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

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
