When the launch velocity is a bit less than the escape velocity, the satellite with time will find itself back to earth and when the speed is far beyond the escape velocity, the satellite with time, be lost in space.
The velocity of escape from the less massive Moon is about 2.4 km per second at its surface. ... A planet (or satellite) cannot long retain an atmosphere if the planet's escape velocity is low enough to be near the average velocity of the gas molecules making up the atmosphere.
Answer:
Average velocity of water flow through the pipe = 3.98 m/s
Explanation:
Diameter of pipe = 20 mm
Discharge = 75 L/min
We know that
Discharge = Area x Velocity

Discharge = 75 L/min

Substituting

Average velocity of water flow through the pipe = 3.98 m/s
<h3>The colour of the shadow of coloured objects is not same as the colour of the objects</h3>
When an opaque item absorbs all of the light falling from a light source, no light is reflected, and the thing appears black. The color of an object's <u>shadow is independent of its hue; it can be red, yellow, green, or black.</u>
Remember opposites attract and same charges repel each other.
Object A= negatively charged.
Object A and B attract so B must be positively charged.
Object B and C repel so because B is positively charged C must also be positively charged.
Object C and D attract and because C is positively charged, D must be negatively charged.
Answer:
e. design programming
Explanation:
The planning techniques are responsible for structuring the tasks to be performed within the project, defining the duration and the order of execution of the same, while the programming techniques try to organize the activities so that the logical temporal relationships between them, determining the calendar or the moments of time in which each one must be realized. The programming must be consistent with the objectives pursued and respect existing restrictions (resources, costs, workloads).
The programming therefore consists in setting, in an approximate way, the moments of beginning and termination of each activity. Some activities may have slack and others are critical activities (fixed over time).
STEPS:
Build a time diagram (moments of beginning and slack of activities).
Establish the times of each activity.
Analyze project costs and adjust clearances (minimum cost project).
