Answer:
Technician B
Explanation:
This can be explained as a fuse is a protective device which blows in order to protect the circuit and the equipment from short circuiting.
Short circuit is a condition where a very heavy current flow through the line with no low line impedance which is not the intended path for the current to flow.
Thus when heavy current flows through a fuse it blows out thus disconnecting the path for the current flow.
Therefore, if a fuse burns out when switch is on, short circuit is present after the switch
Answer:
Group IA elements have only one valency electron while Group IIA have two valency electrons.
Group IA elements have cations with higher charge density hence polarizing anions easier resulting into covalent character while Group IIA elements have cations with lower charge density hence difficulty in distorting anions resulting into a ionic character. This is due to difference in cationic radii and charges
Answer:
coordinates of the center of mass for these two rods
(
, 
)= (
, )cm
Explanation:
given
mass of a rod = 2m
length of the rod = 3L
mass of two rods = 2(2m) = 4m
radius = diameter/2 = 
attached is the diagram and solution to the question
Answer:
0.16 m
Explanation:
A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).
50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³
The volume of the rectangular tank is:
volume = width × length × depth
depth = volume / width × length
depth = 0.074 m³ / 0.500 m × 0.900 m
depth = 0.16 m
