What is the unit of angle of contact?
Contact angle is the angle that a drop of liquid makes as it meets the surface or interface of another phase, usually a solid
A right angle is an angle that has a?
A right angle is a angle with 90o
What type of angle is a 98 angle?
An angle of 98 degrees is an obtuse angle
Prove that the perpendicular at the point of contact to the tangent to a circle passes through the center?
Draw a circle with centre O. draw a tangent PR touching circle at P. Draw QP perpendicular to RP at point P, Qp lies in the circle. Now, angle OPR = 90 degree (radius perpendicular to tangent) also angle QPR = 90 degree (given) Therefore angle OPR = angle QPR. This is possible only when O lies on QP. Hence, it is prooved that the perpendicular at the point of contact to the tangent to a circle passes through the centre. Answer By- Rajendra Meena, Jaipur, India. email: rajendra.meena21@gmail.com
What angle does a hemisphere have?

What is contact angle in penetrant test?
The contact angle is the angle in which the liquid interface meets the solid surface. The contact angle should be as small as possible to have an effective penetrant material.
What is the unit of angle of contact?
Contact angle is the angle that a drop of liquid makes as it meets the surface or interface of another phase, usually a solid
Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
How do you measure the contact angle?
There are many ways to measure a contact angle, but the simplest way is to use a goniometer. The image of the droplet is taken with a high resolution camera; the angle can then be measured using a protractor.
The angle between a tangent and the radius of a circle att the point of contact is?
It is a right angle
Definition of lift angle?
The angle of rotation of the balance in which the roller pin is in contact with the pallet forks.
What has the author Chien-kuo Yang written?
Chien-kuo Yang has written: 'Use of the equilibrium contact angle as an index of contact surface cleanliness' -- subject(s): Contact angle, Surfaces (Technology), Analysis
What is the adjacent side of a right triangle?
A right angled triangle has three sides. The naming of these sides is dependant on which angle you are observing. The first side is named the opposite and is the side which is not in contact with the angle that is being observed (each angle is in contact with ONLY two sides) The second side is the hypotenuse which is the side opposite to the right angle. Also termed the diagonal, the hypotenuse is the longest side of the triangle. The third side, the one you are interested in, is the adjacent side which is the angle which is in contact with the angle being observed which ISN'T the hypotenuse or the opposite. It can be determined by a process of elimination in that there are two sides in contact with the observed angle.
What is the angle of contact if forces of adhesion and cohesion are same?
zero
Angle of contact between journal and bearing?
0 degree
Which angle hits a mirror or glass block?
The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.
What is the formula to calculate the optimum cutting angle of contact for cutting scissors or drum lawn mowers?
There is not an angle associated with this, the degree of contact between the reel and the bedknife is the adjustment. See links below.
