63 kg = 617N 617/180 = 3.43 N/cm2 or 34 300 Pascal while standing on one foot with two significant digits (mass was given with an accuracy of two digits) 17Kpa (kiloPascal) if he is standing with both feet weight evenly distributed across the soles of his feet.

When is the pressure on the ground more when a man is lying or when a man is standing?
The person of mass (m) exerts the same force on the ground both standing up and lying down. This can be easily seen through Newtons Second Law ie F = ma. Knowing that pressure is defined as force over area (P = F/Area), it can be seen that the person standing up is applying more pressure to the ground.
What are examples of normal force?
a person standing still on the ground
What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
The weight of a person can be represented by a vector that acts?
The weight of a person can be represented by a vector that acts downwards.
You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
the person standing on the ground, the train is moving and the ground is stationary. but the person on the train looks he is stationary and the ground is moving.
Which produces more pressure on the ground a person standing up or the same person laying down?
standing up, did this on web assign

What is the systolic and diastolic pressure of the aorta?
The systolic and diastolic pressures are the pressure exerted against the artery walls. This will vary from person to person. There is no one answer to your question.

What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
Which exerts more force on the ground a person lying down or standing up?
in which situation you exert more force downward, standing or lying horizantilly?
The weight of a person can be represented by a vector that acts?
The weight of a person can be represented by a vector that acts downwards.

Why there is no trail left behind after skiing on ice?
When a person skis on ice, the ice under the ski melts due to the pressure exerted by the weight of the person. After the person moves from ice, the melted ice freezes again, thus leaving no trace behind.
Why can't a person standing on the ground hear a supersonic airplane until it has flown past the person?
Because the plane is flying faster (and therefore ahead of) its own sound.
For what purposes is a tonometer used?
The purposes that a tonometer is used for measuring the pressure exerted by the fluid inside a person's eyes in mmHg. This is done to make sure the eyes and optic nerves are healthy.
Is there any difference between force and pressure?
Pressure is the exertion of force upon a surface by an object, fluid, etc., in contact with it: the pressure ofearth against a wall.Force is the strength or power exerted upon an object; physical coercion; violence: to use force to open the window; to use force on a person.
