Answer:
B) more current.
Explanation:
When two lamps are connected in series then we have
now let the two lamps are identical
so we have
now the total resistance of the lamps is given as
now the current in that case is given as
Now when lamps are connected in parallel
net resistance of two lamps is given as
so now we have
so we have
so now the current through the battery will be
So current will be more when two lamps are connected in parallel

Answer:
405m
Explanation:
h = ut +1/2gtsquare so
h = 0×9.0 + 1/2 × 10×9.0square
h = 0 + 1/2 × 810
h = 405m
Correct option: A
An object remains at rest until a force acts on it.
As the water moves faster, it applies greater force on the sediment, which over comes the frictional forces between the bed and the sediment. So, when the river flows faster, more and larger sediment particles are carried away. When the flow slows down, the river couldn't apply enough force on the larger sediments which can overcome the frictional force between the sediment and the river bed. So, the net force on the heavier particles become zero. Hence, the heavier particles of the load will settle out.
Answer:
Alpha particle
Explanation:
Alpha particles emitted by radioactive nuclei consist of 2 protons and 2 neutrons bound together which makes it neutral and are able to pass through ordinary matter almost undisturbed
