Answer:

a) Force required to keep both the masses in rest will be - 77 N  

b) The coefficient of friction will be 0.55

Explanation:

a) As the weight of 77 N is suspended vertically so, there must act 77 N force on the 140 N weight to keep both masses in rest. Hence, the answer is -77 N.

b) We know that:

                            140µ = 77

                                  µ = 77/140

                                  µ = 0.55

Hence, the minimum co-efficient of friction required to keep both bodies in rest will be 0.55.

Why does the number of dwarf planets recognized by astronomers in the solar system sometimes increase?
gregori [183]
Because sometimes it happens that they discover a dwarf planet
that nobody ever knew about before.  When that happens, they
ADD the new one to the list of known dwarf planets, and then the
total number of dwarf planets on the list increases by 1 .

Question 30
stellarik [79]

Answer: 0.69\°

Explanation:

The angular diameter \delta of a spherical object is given by the following formula:

\delta=2 sin^{-1}(\frac{d}{2D})

Where:

d=16 m is the actual diameter

D=1338 m is the distance to the spherical object

Hence:

\delta=2 sin^{-1}(\frac{16 m}{2(1338 m)})

\delta=0.685\° \approx 0.69\° This is the angular diameter
