When the cores collapse to form dense stellar objects called neutron stars, they blast off the outer layers of the star in a supernova. In higher-mass red supergiants, however, carbon doesn't burn convectively; this limits neutrino losses and leads to a more extended core with dense material around it.

While the core collapses, the outer layers of material in the star to expand outward. The star expands to larger than it has ever been – a few hundred times bigger! At this point the star is called a red giant. What happens next depends on how the mass of the star.

A 0.10-kg ball, traveling horizontally at 25 m/s, strikes a wall and rebounds at 19 m/s. What is the 7) magnitude of the change
IRISSAK [1]

Answer:

Change in momentum will be -4.4 kgm/sec

So option (A) is correct option

Explanation:

Mass of the ball is given m = 0.10 kg

Initial velocity of ball v_1=25m/sec

And velocity after rebound v_2=-19m/sec

We have to find the change in momentum

So change in momentum is equal to =m(v_2-v_1)=0.1\times (-19-25)=-4.4kgm/sec ( here negative sign shows only direction )

So option (A) will be correct answer

A plate has an area of 1m square. It slide down an incline plane , having an angle of inclined 60° to horizontal, which a veloci
Solnce55 [7]

Answer:

\mu =0.169704 Ns/m^2

Explanation:

From the question we are told that

Area of platea=1m^2

Angle of inclination \theta=60 \textdegree

Velocity v=0.75m/s

Thickness of oil t=2mm

Weight of plate w=90N

Generally the equation for shear force is mathematically given by

F=mgsin45 \textdegree

F=90sin45 \textdegree

F=63.639N

F=\mu* \frac{v}{t}

F=\mu* \frac{0.75}{2*10^-^3}

\mu* \frac{0.75}{2*10^-^3}=63.639N

\mu =\frac{63.639}{375}

Therefore viscosity is given by

\mu =0.169704 Ns/m^2
