What event was seen as a symbol of the gradual relationship improvements between the United States and the Soviet Union as the Cold War was coming to an end?
A. The Soviet space center and the US space center signed a treaty agreeing to put the past behind them and work together for future space endeavors.
B. A handshake that occurred between the commanders of a US and Soviet space craft that were involved in a joint moon mission.
C. Astronauts from both countries taking a trip to the moon together aboard one space craft.
D. A male astronaut from the Soviet Union and a female astronaut from the US walked on the moon together.

I think the answer is b but i cannot confirm cuz this is a challenging question

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
