Answer:
B. OSMOTIC PRESSURE WILL BE LOWER IN THE ARTERIOLE END OF THE CAPPILLARY BED COMPARED TO THE VENOUS END.
Explanation:
This is true for filtration to take place in the cappillary bed. Osmotic pressure is the net pressure that drives movement of fluid from the interstitial fluid back into the capillaries. Osmotic pressure increase favors reabsorption as water moves from region of higher water concentration in the interstitial fluid to the lower region of water concentration in the capillaries.
At the ends of a capillary bed, the difference in the hydrostatic and osmotic pressures provides a net filtration or reabsorption ratio. At the arteriole end of the capillary bed, hydrostatic pressure is greater than the osmotic pressure allowing movements of fluid to the interstitial fluid (filtration) while as the blood moves to the venous end, the osmotic pressure becomes greater than than hydrostatic pressure.
As we know that average speed is given by the ratio of total distance covered and total time of motion so we will have
now we have
distance covered = 40 meter
time taken by the bird = 10 minutes
now in order to find the average speed of the bird
so the average speed of the bird is 4 m/min
Answer:erosion
Explanation:
Erosion refers to the process by which land is worn away by natural forces or human activities
Explanation:
μ = coefficient of friction.
F = Frictional force = 12N
R = Normal reaction = mg = Weight = 240N
m = mass
g = acceleration due to gravity ≈ 9.8ms—²
μ = F/R
<em>μ </em><em>=</em><em> </em><em>1</em><em>2</em><em>/</em><em>2</em><em>4</em><em>0</em>
<em>μ </em><em>=</em><em> </em>¹/20
μ = 0.05
Answer:
12 A
Explanation:
Given,
Power of electric kettle=2.2 kW=2200W (since 1kW=1000W)
Voltage=180V
Current=?
Power = Voltage*Current
Current = Power ÷ Voltage
=2200W ÷ 180V
=12.22 Ampere
=12 A
