(III) A patient is to be given a blood transfusion. The blood is to flow through a tube from a raised bottle to a needle inserted in the vein (Fig. 13–56). The inside diameter of the 25-mm-long needle is 0.80 mm, and the required flow rate is 2.0 cm3 of blood per minute. How high h should the bottle be placed above the needle? Obtain ρ and η from the Tables. Assume the blood pressure is 78 torr above atmospheric pressure.

- please solve and answer the question correctly. Thank you!!arrow_forwardAssuming the normal angle for stairs in a house, 37.0˚ with the horizontal, what is Kevin’s acceleration down the stairs? The sled is always touching at least one stair so you can treat it the same as a ramp. The coefficient of kinetic friction between the sled and the carpeted stairs is 0.708.arrow_forwardA helicopter pulls up and back on the truck with a force of 5.78⋅10^4 N at an angle of 30.0˚ from the horizontal. The truck has a mass of 5.04⋅10^3 kg. The truck’s engine applies a force on the truck that is in the x direction causing the truck to accelerate at 2.09 m/s2 in x. A) What is the force the engine is exerting? B) What is the normal force acting on the truck? Assume no acceleration in y.arrow_forward
- Mikasa and her allies, from Attack on Titan, uses omni-directional mobility gear (ODM gear) to move from place to place. The ODM gear launches out wires with grappling hooks they can use to swing through the city. Mikasa, who has a mass of 68.0 kg, holds herself in place not moving with two wires from the ODM gear, as shown below with θ1 = 39.3°. If the tension in the wire labeled T1 is 688 N, what tension, magnitude and direction, is needed in T2?arrow_forwardDoctor Strange’s cloak allows him to levitate, and glide forward. Dr. Strange’s cloak does this by applying a F at an angle of 70.0˚, A) What force must the cloak be exerting to keep a Dr. Strange at a set height, neither lowering nor rising? Dr. Strange has a weight of 147 lbs. (2.20 lb = 1 kg). B) When the force found in part A is applied, what is Dr. Strange’s acceleration?arrow_forwardplease solve and answer the question correctly.

- please solve and answer the question correctly. Thank you!! ( Hint attached in second photo)arrow_forwardA) If the lightsaber has a mass of 2.14 kg, what minimum force would be required to pull the lightsaber to her, assuming it does not leave the table’s surface and the force is completely horizontal? The coefficient of static friction is 0.300 and the coefficient of kinetic friction is 0.173. B) What acceleration does the lightsaber have when it starts moving? Assume Rey is pulling with the same force you found in Aarrow_forwardQuestion is below, thank you.arrow_forward
- Mario kicks a 5.08 kg Koopa shell causing it to undergo an acceleration of 2.55 m/s2 . A) What is the magnitude of the force Mario applies to the shell? B) If Mario applies this same force to a shell that instead has a mass of 4.08 kg, what acceleration is produced?arrow_forwardplease solve and answer the question correctly.
