=112yd²
Because 2x4=8
8x2=16
8x4=32
32x2=64
2x8=16
16x2=32

16+64+32=112

In the diagram shown, satellite S moves in a circular orbit around the Earth (E) in a counterclockwise direction.
zubka84 [21]

The characteristics of the velocity vector used to find the results for the direction of acceleration and velocity are:

  • Acceleration is towards the center of the circle
  • The velocity is tangent to the circle counterclockwise.

Newton's Second Law establishes a relationship between force, mass and acceleration of bodies.

<h3>Centripetal acceleration. </h3>

In the case of circular motion there is a constant change in the direction of the velocity vector, even when its module remains constant, this change in direction points towards the center of the circle, so that the module is constant.

They indicate that the satellite is moving counterclockwise, therefore the speed must go to the left (counterclockwise) tangential to the circle.

In conclusion using the characteristics of the velocity vector we can find the results for the direction of acceleration and velocity are:

  • Acceleration is towards the center of the circle
  • The velocity is tangent to the circle counterclockwise.

Alex787 [66]

Answer:

Two marbles are launched at t = 0 in the experiment illustrated in the figure below. Marble 1 is launched horizontally with a speed of 4.20 m/s from a height h = 0.950 m. Marble 2 is launched from ground level with a speed of 5.94 m/s at an angle above the horizontal. (a) Where would the marbles collide in the absence of gravity? Give the x and y coordinates of the collision point. (b) Where do the marbles collide given that gravity produces a downward acceleration of g = 9.81 m/s2? Give the x and y coordinates.

Part of one row of the periodic table is shown. Which element’s atoms have the greatest average number of neutrons?
Zanzabum

Number of neutrons of the elements can be calculated if the atomic number and mass number is known.

As, Number of neutrons= Mass number- Atomic number

For Tin(sn), the mass number is 119 and atomic number is 50, then

Number of neutrons= 119-50=69

For Antimony(sb), the mass number is 122 and the atomic number is 51, then

Number of neutrons=122-51=71

For Tellurium(te), the mass number is 128 and atomic number is 52,then

Number of neutrons=128-52=76

Fro Iodine(I), the mass number is 127 and the atomic number is 53, then

Number of neutrons=127-53=74

Since, the number of neutrons are large in Tellurium, therefore Tellurium have the greatest average number of neutrons.
