Answer: 1.03 × 10⁵ N

Explanation:

Force of gravity due to liquid column in a tank is given by the product of pressure due to the liquid column and area on which this pressure is acting.

Force, F = P × A

Pressure, P = ρ g h

where, ρ is the density of the liquid

g is the acceleration due to gravity

h is the height of the liquid column

It is given that, h = 7 m

Area, A = 1.5 m²

g = 9.81 m/s²

density of water, ρ = 1000 kg/m³

⇒ F =  ρ g h × A = 1000 kg/m³ × 9.81 m/s² × 7 m × 1.5 m² = 103005 N

Hence, force of gravity acting on the column of water is 1.03 × 10⁵ N

Why is velocity a vector quantity
Jobisdone [24]
Velocity as a Vector Quantity
Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.

What are the concepts of dynamically continuous innovation and discontinuous innovation? Can you share examples to illustrate th
KiRa [710]

Answer:

Explained

Explanation:

Dynamically continuous innovation:

- Falls in between continuous and discontinuous innovation.

-Changes in customer habits are not as large as in discontinuous innovation and not as negligeble as in continuous innovation.

best example can as simple as transformation in  Television. New HD TVs have flat panels, wide screens and improved performance The Added features are considered dynamically improved.

Discontinuous innovation:

- discontinuous innovation comprise of new to world product only so they are discontinuous to every customer segment.

- these product are so fundamentally different from the the product that already exist that they reshape market and competition.

For example- the mobile and the internet technology are reshaping the market through regular innovation and change.

How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet? A. 2,260.8 cubic feet B. 13,5
MakcuM [25]

Answer:

Volume, V = 13564.8  cubic feet

Explanation:

It is given that,

Radius of the cylindrical tank, r = 12 feet

Height of the tank, h = 30 feet

We need to find the water that can be held by a cylindrical tank i.e. we need to find the volume of the tank. It is given by :

V=\pi\times r^2\times h

V=3.14\times (12)^2\times 30

V = 13564.8  cubic feet

So, the water held by the tank is 13564.8  cubic feet. Hence, this is the required solution.
