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.

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

An object is moving forward with a constant velocity. Which statement about this object MUST be true?

Greeley [361]

If the object's velocity is constant ... (it's speed isn't changing AND it's moving in a straight line) ... then the net force on the object is zero. (D)

Either there are no forces at all acting on the object, OR there are forces on it but they're 'balanced' ... when you add up all of their sizes and directions, they just exactly cancel each other out, and they have the SAME EFFECT on the object as if there were no forces at all.

A box of mass 14 kg sits on an inclined surface with an angle of 52degrees. What is the component of the weight of the box along

kolezko [41]

First, we calculate for the weight of the object by multiplying the given mass by the acceleration due to gravity which is equal to 9.8 m/s²
Weight = (14 kg)(9.8 m/s²)
Weight = 137.2 N
The component of the weight that is along the surface of the inclined plane is equal to this weight times the sine of the given angle.
Weight = (137.2 N)(sin 52°)
weight = 108.1 N

Determine the binding energy per nucleon of an mg-24 nucleus. the mg-24 nucleus has a mass of 24.30506. a proton has a mass of 1

My name is Ann [436]

The mass of Mg-24 is 24.30506 amu, it contains 12 protons and 12 neutrons.

Theoretical mass of Mg-24:

The theoretical mass of Mg-24 is:

Hydrogen atom mass = 12 × 1.00728 amu = 12.0874 amu

Neutron mass = 12 x 1.008665 amu = 12.104 amu

Theoretical mass = Hydrogen atom mass + Neutron mass = 24.1913 amu

Note that the mass defect is:

Mass defect = Actual mass - Theoretical mass : 24.30506 amu- 24.1913 amu= 0.11376 amu

Calculating the binding energy per nucleon:

$\frac{B.E.}{nucleon}=\frac{(0.11376amu)(931Mev/amu}{24nucleons} = 4.41294 Mev/nucleon$

So approximately 4.41294 Mev/necleon
