By definition, the tensile bond strength of a material mainly depends on the maximum tensile stress it could handle before it would eventually collapse like breaking. The concept is very significant in the field of construction industries so that proper structuring would promote safety to people.
Answer:
More than four-fifths of the single points of light we observe in the night sky are actually two or more stars orbiting together. The most common of the multiple star systems are binary stars, systems of only two stars together.o
Answer:
The gravitational force is related to the mass of each object.
The gravitational force is an attractive force.
Explanation:
Gravitational force is a long range force of attraction between any two masses.
Mathematically given as :
where:
are the masses
r= distance between the center of mass of the two objects.
G= gravitational constant =
From the above relation of eq. (1) it is clear that,
Gravitational force is inversely proportional to the square of the distance and directly proportional to the masses.
The mass of an object is independent of its size due to the fact that density may vary for different objects.
The force of gravity varies with height as:
where:
gravity at height of the center of mass of the object from the center of mass of the earth.
and we know that force:
where: m= mass of the object.
Answer:
20 kg
Explanation:
The following data were obtained from the question:
Force (F) = 100 N
Acceleration (a) = 5 m/s²
Mass (m) =?
Force (F) is simply defined as the product of mass (m) and acceleration (a). Mathematically, the force (F) can be expressed as:
Force (F) = mass (m) × acceleration (a)
F = ma
With the above formula, we can simply obtain the mass of the object as follow:
Force (F) = 100 N
Acceleration (a) = 5 m/s²
Mass (m) =?
F = ma
100 = m × 5
Divide both side by 5
m = 100 / 5
m = 20 kg
Thus, the mass of the object is 20 kg.
Answer:
0.05T
Explanation:
Data given,
area, A=20cm*33cm=0.2m*0.33m=0.066m^2
Number of turns, N=110 turns,
Emf= 72v,
angular speed, <em>W= 200rad/s</em>
<em>magnetic field strength, B= ??</em>
from the expression showing the relationship between induced emf and magnetic field is shown below
Where N is the number of turns,
E=is the emf,
Bis the magnetic field strength
if we substitute values, we arrive at
