Answer:
I believe it is B, not 100% sure though
Explanation:
Explanation:
As the given data is as follows.
ohm, ohm,
= 1200 (as 1 k ohm = 1000 m)
(a) We will calculate the maximum resistance by combining the given resistances as follows.
Max. Resistance =
= ohm
= 2600 ohm
or, = 2.6 ohm
Therefore, the maximum resistance you can obtain by combining these is 2.6 ohm.
(b) Now, the minimum resistance is calculated as follows.
Min. Resistance =
=
= ohm
Hence, we can conclude that minimum resistance you can obtain by combining these is ohm.
Density is defined as (mass) per unit (volume). So in order to calculate
the density of a glob of some substance, you pretty much have to measure
its mass and its volume.
The rock strike the water with the speed of 15.78 m/sec.
The speed by which rock hit the water is calculated by the formula
v=
v=
v=15.78 m/sec
Hence, the rock strike the water with the speed of 15.78 m/sec.
