Answer:
1.2 g/cm³
Explanation:
From the question given above, the following data were obtained:
Mass of solid = 180 g
Length (L) of solid = 10 cm
Width (W) of solid = 5 cm
Height (H) of solid = 3 cm
Density of solid =?
Next, we shall determine the volume of the solid. This can be obtained as follow:
Length (L) of solid = 10 cm
Width (W) of solid = 5 cm
Height (H) of solid = 3 cm
Volume (V) of solid =?
V = L× W × H
V = 10 × 5 × 3
V = 150 cm³
Finally, we shall determine the density of the solid. This can be obtained as follow:
Mass of solid = 180 g
Volume of solid = 150 cm³
Density of solid =?
Density = mass / volume
Density = 180 g / 150 cm³
Density of solid = 1.2 g/cm³
It depend on how far it is from the earths base
Answer:
<u>Rigid bodies:</u> Options d and e
<u>Rigid bodies' system:</u> options f, g and h
<u>Non-rigid bodies:</u> Options a, b and c
Explanation:
The above classification of the mentioned objects into rigid bodies, non rigid bodies and system of rigid bodies can be explained as :
Rigid body: A body which does not undergo any change in its form or shape on application of externally applied load or force is said to be a rigid body.
System of Rigid bodies:
A system of rigid bodies is different from any other element system as in this the bodies constituting the system must be rigid bodies.
Non-rigid bodies:
A body which undergoes a change in its form or shape on application of externally applied force or load is said to be a non-rigid body.
Answer:
400 Newtons to the right.
Explanation:
You have 300 Newtons that are being applied to the right and you also 100 Newtons to the right. When calculating net force with the forces that go the same direction, you add them. 300 plus 100 is 400. Therefore, it is 400 Newtons or N to the right. Hope this helps!
Answer:
B). to the right
Explanation:
Since the direction of magnetic field is into the page
So here we know that
now the velocity is from bottom to top
so we have
now the force on the moving charge is given as
now we have
so force will be towards Right
