Answer:
Explanation:
submerged volume of pump = 40 x 12⁻³ ft³
density of oil = .9 x 62.4 lb ft⁻³ ( specific gravity x density of water )
mass of displaced oil = 40 x 12⁻³ x .9 x 62.4 lb
= 1.3 lb
buoyant force = 1.3 lb
weight of pump = 14.6 lb
extra force needed for balancing pump by spring
= 14.6 - 1.3
= 13.3 lb .
Answer:
increases by a factor of 4.
Explanation:
The power dissipated through a resistor is I2RI2R
Current=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2RCurrent=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2R
Thus, doubling the current increases the power dissipated through a resistor by a factor of four.
Answer:
Situation 2, 4, 5
Since there are five situations I just numbered them 1-5
A carnivore would become a scavenger if the food supplies is low and they have to restore to cannibalism. Being both a carnivorous and a herbivorous feeding behavior in which the scavenger feeds on dead animal and plant material present in its habitat. The eating of carrion from the same species is referred to as cannibalism.
I hope this helped.
