Show a common scale and convert each choice to it ( I will choose Celsuis):
A)100C
B) 100F = 37 C
C) 100 - 273 = -173 C
so the answer is A
Answer: Creative thinking
Explanation:
It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.
The thought that is present in mind is tries in the practical life so that the problem can be solved.
Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.
This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.
Answer:
T=270 K
Explanation:
Power absorbed by the Moon
the reason for choosing the area as π R^2 and not 4π R^2 is because the absorbed light is only from the surface facing the Sun which is a disc.
Using Stefan Boltzmann's law,
So, using Conservation of Energy,
this gives, T = 270 K. This is the temperature of the sunlight side of the Moon.
As we know that gravitational force on two planets will be given as
let
mass of star = M
mass of two planets are m1 and m2
their distance from star is r1 and r2
since the gravitational force of star is given on two planets to be same
so here we can say
now if the ratio of mass and distance is same then we can say that closer planet must have lesser mass to hold good for above equation
so correct answer will be
B) Yes, it is possible if the closer planet has less mass.
