State the dimension of surface tension​

Physics
1 answer:
Luda [366]3 years ago
3 0

Answer:

Actually, surface tension is the to force per unit length. That means formula for surface tension is = force/length . As we know that the dimensional formula for length is L . And that for force is MLT^-2. So the dimensional formula for surface tension can be obtained by dividing the dimensional formula of force and length.

<h3>What is an atom?</h3>

An atom can be defined as the smallest particle of an element which can take part in a chemical reaction.

Some elements are

  • Monoatomic; eg: C
  • Diatomic; eg: O2
  • Triatomic and others
  • Polyatomic

So therefore, an atom or ion which does not have the same electronic configuration as the species [kr] is K+

Suppose you throw a ball vertically upward with a speed of 49 m/s. Neglecting air friction, what would be the height of the ball
vlabodo [156]

Answer:

78.4 m

Explanation:

Using newton's equation of motion,

S = ut + 1/2gt²......................... Equation 1

Where S = Height, t = time, u = initial velocity, g = acceleration due to gravity.

Note: Taking upward to be negative, and down ward positive

Given: u = 49 m/s, t = 2.0 s, g = -9.8 m/s²

Substitute into equation 1

S = 49(2) - 1/2(9.8)(2)²

S = 98 - 19.6

S = 78.4 m

Hence the height of the ball two seconds later = 78.4 m
