The RIDER is lifting the people into the air?
Oh well.
acceleration of gravity = 9.81 m/s**2
mass = 70kg x 15
Force (N) = mass (kg) x acceleration (m/s**2)
Force = 70*15*9.81
Force = 10300.5 N
Of course someone would have to give it an extra nudge so that it'll get going
Yes, it does. People use it's energy to produce electricity.
Loud speakers can produce ultrasonic waves. But since the normal purpose of loud speakers is to produce sounds for people to hear, there is seldom a reason to produce sounds that people can't hear (other than to annoy certain animals).
On average, twice as much as one person.
B. The sources creator could personally benefit from convincing people to accept his argument.
Energy from the sun comes in the form of radiant enery. Without this gift of God, we would all die. Humans use radiant energy to produce power. Plants use radiant energy to produce their food and live. Plants are essenlial to human life and hence radiant energy helps people a lot.
electrical engineers
As with all people, some engineers are and some engineers aren't good at written communication.
Engineers and technicians.
They are called Engineers.
Because they do assume that there is a Devil.
Quite common, there are 7 billion people in the world, there are a LOT less engineers than non-engineers.
. those people who want to develop newthings, or they want to be called as paioneer of something they develop they are called as engineers, its not just an hobby, it is a passion..
That's impossible to determine because it varies on the different regions, but I assume that it is around 2000 Kcal.
Depends. People that develop explosives are Chemical Engineers. People that design the USE of explosives may be Civil Engineers, or Mining Engineers. However, many everday users of explosives for mining and construction do not have a degree.
Space engineers.
