Arocket burns fuel at a rate of 180 kg/s and exhausts the gas at a relative speed of 1 km/s. find the thrust of the rocket. answer in units of mn.

0.18 MN

Explanation:

m = Mass

t = Time taken

u = Initial velocity = 0

v = Final velocity = 1 km/s

= Mass flow rate = 180 kg/s

Force is given by

The thrust on the rocket is 0.18 MN

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

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
