Specific heat capacity= m c Δ t
= 20 * 0.11* (75-25)
= 20* 0.11* 50
= 110 calories.
Each elements is made up only one atom. Atom is the basic unit of matter.
Here easy answer from online
In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.
Answer:
Moment of the 4N force = 16Nm
Moment of the 6N force = 12Nm
Explanation:
Find the diagram attached.
Moment of a force is the product of the force and the perpendicular distance from the point of application
For the 4N force
Distance of the force from O is 4m
Moment of the 4N force = 4N * 4m
Moment of the 4N force = 16Nm
For the 6N force
Distance of the force from O is 2m
Moment of the 6N force = 6N * 2m
Moment of the 6N force = 12Nm
