A planet has been observed orbiting a nearby star. This star has a mass of 3.5 solar masses, and the planet is 4.2 AU from the star. What is the planet’s orbital period in Earth years? Round your answer to the nearest whole number.

the answer is kevlar

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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
