Answer:

The correct answer is c. There is no component of force acting along the direction of motion of the satellite.

Explanation:

When a moving object is traveling in a circular orbit at a constant speed we assume it has a changing velocity, this is mainly because velocity is a vector quantity that rely on the speed the object is moving and direction, because of the variation of acceleration throughout the whole orbit and the lack of other force acting along the direction of motion of the satellite allows the object to travel at a constant speed, but variable acceleration.

Solnce55 [7]

Answer:

labor force participation rate = 61.28 %

Explanation:

given data

adult population = 250 million

unemployment = 10.4 million

employment = 142.8 million

marginally attached workers = .8 million

to find out

labor force participation rate

solution

we know that labor force participation rate is equal to  100 × labor force (no of people employed + no of people unemployed) and  divided by the adult non institutionalized population

so here

labor force participation rate = 100 × \frac{142.8 + 10.4}{250}

labor force participation rate = 61.28 %

2. A solid is in the form of a right circular cylinder with a hemisphere at one end and a cone at the other end the radius of th
Law Incorporation [45]

Answer:

Total Surface Area of Solid = C.s.a of hemisphere+C.s.a of cone+C.s.a of Cylinder

slant height of cone=√h²+r²

=√6²+8²

=√100

=10cm

height of cone = 10 cm

radius of hemisphere =radius of cone=radius of cylinder=8cm

T.S.A of solid=2πrh+2πr²+πrl

=πr[2h+2r+l]

=3.14*8[2*10+2*8+10]

=25.12[36+10]

=25.12*46

=1155.52 cm²

Explanation:

hope this helps
