Answer:

speed are different at different places

Explanation:

because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other

Satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an
Volgvan

Answer:

0.63

Explanation:

We are given that

Radius of earth,R_E=6370 km

Radius of orbit A,R_A=7590+6370=13960 km

Radius of orbit B,R_B=6370+15800=22170 km

We have to find the ratio of the potential energy of satellite B to that of satellite A in orbit.

Potential energy of orbit A=U_A=-\frac{GM}{R_A}=-\frac{GM}{13960}

Potential energy of orbit  B=U_B=-\frac{GM}{R_B}=-\frac{GM}{22170}

\frac{U_B}{U_A}=\frac{13960}{22170}=0.63

Hence,the ratio of the potential energy of satellite B to that of satellite A in orbit=0.63

statuscvo [17]

Horizontal angulation is Select one: a. the side-to-side angulation. b. different when using the paralleling and bisecting techniques.

Angles that are horizontal. relates to the central ray's placement in a horizontal, or side-to-side, plane.

A picture with an overlap of nearby structures in the horizontal plane is produced by situating the central ray such that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth (the contact areas of the teeth are superimposed over each other).

Fracture angulation refers to a particular kind of fracture displacement in which the bone's natural axis has been changed so that the distal end now points off in a different direction. When using a bite-wing tab, the x-ray beam's center ray must be pointed at the contact points between teeth. The x-ray beam must be centered on the receptor to guarantee that the receptor is exposed.

What has more gravity-Earth's moon or the Sun?Why?
charle [14.2K]

Answer:

Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
