Which of the following statements is true regarding how blackbody radiation changes as the temperature of the radiating object i

Answer:10.961 N

Explanation:

Given

mass flow rate in bucket is

mass of bucket

velocity of sand

Force acting on bucket due to incoming of sand is given by

Now weight of sand and bucket when 0.55 kg sand is Present in bucket

Total reading on scale will be addition of weight and force acting by incoming sand

Answer:0.931 s

Explanation:

Given

initial speed=1.1 m/s

height(h)=28 m

after 0.5 sec blue ball is thrown upward

Velocity of blue ball is 24.4 m/s

height with which blue ball is launched is 0.9 m

Total distance between two balls is 28-0.9=27.1 m

Let in t time red ball travels a distance of x m

--------1

for blue ball

-----2

Add 1 & 2

we get

t=0.931 s

after 0.931 sec two ball will be at same height

Answer:

Distance in mm will be 0.3718 mm

Explanation:

We have given charge surface charge density

We know that electric field due to surface charge density is given by

We have given potential difference V = 105 volt

We know that potential difference is given by

So
