What is an essential characteristic of an object in equilibrium

Physics
1 answer:
Alecsey [184]3 years ago
6 0

Answer:

The essential characteristics of an object in equilibrium is acceleration of the object must  be zero.

Explanation:

Equilibrium: An object acted upon by several forces is said to be in equilibrium if it does no it moves or rotate. Equilibrium can be defined as the state of stability of an object.

Condition for equilibrium

(i) The resultant force acting on the object must me equal to zero.

(ii) The sum of moment acting on the object must be equal to zero.

But.

F = ma..................... Equation 1

Where F =  net force , m = mass, a = acceleration.

from the equation above,

For  F = 0 N, a must be equal to zero.

<em>From the above, the essential characteristics of an object in equilibrium is acceleration must be zero</em>

Which statements describe using genetic factors to influence the growth of organisms? Select the three (3) that apply.
Damm [24]

Answer:

- increasing use of hybrid crops

- altering genes in DNA to create new plants

- developing disease or pest resistant crops

Explanation:

The use of genetic factors to influence the growth of a plant encompasses manipulating the genetic constituent (gene) of such plant.

For example,

- Increasing use of hybrid crops entails mating two pure bred plants based on a gene of interest responsible for a particular trait, to form a hybrid.

- Altering genes in DNA to create new plants is also a genetic factor as it has to with gene modification.

- developing disease or pest resistant crops means that the genetic make up of such plant has been modified to be resistant to pest/disease.

A circular plate of 500-mm diameter is maintained at T1 = 600 K and is positioned coaxial to a conical shape. The back side of t
drek231 [11]
For part a)
Since the conical surface is not exposed to the radiation coming from the walls only from the circular plate and assuming steady state, the temperature of the conical surface is also equal to the temperature of the circular plate. T2 = 600 K

For part b)
To maintain the temperature of the circular plate, the power required would be calculated using:
Q = Aσ(T₁⁴ - Tw⁴)
Q = π(500x10^-3)²/4 (5.67x10^-8)(600⁴ - 300⁴)
Q = 5410.65 W
