What is the answers for each Q10 and Q11?
the magnitude of the force (fn) that is shown in the figure depends on
A drug is being delivered into a patient’s arm at a rate of 319 mL/min. This drug has a density of 1050 kg/m^3 and viscosity of 8.90×10^–4 Pa.s . Determine its flow type when its move from a syringe through a needle with an internal diameter of 1 mm?
rifle is aimed horizontally towards a target 200m away, If the velocity of the bullet is 2000m/s, the bullet will hits the target a : a)0.15m, B)0.05, c) 0.2 m
a. Draw a force diagram for each block. b. What is the magnitude of the acceleration of each block? c. What is the magnitude of the force that each block exerts on the other?
Two gliders with different masses move toward each other on a frictionless air track and undergo elastic collision. Find the velocity of each glider after the collision. (v_1i = 2.0 m/s ; v_2i = -2.0 m/s ; m_1 = 0.50 kg ; m_2 = 0.30 kg) Answer: -1 m/s; 3 m/s
A 2000-kg elevator with broken cables in a test rig is falling at 4.00 m/s when it contacts a cushioning spring at the bottom of the shaft. The spring is intended to stop the elevator, compressing 2.00 m as it does so. During the motion a safety clamp applies a constant 17,000-N friction…
1) We want to slide a 12-kg crate up a 2.5-m-long ramp inclined at 30°. A worker, ignoring friction, calculates that he can do this by giving it an initial speed of 5.0 m>s at the bottom and letting it go. But friction is not negligible; the crate slides only 1.6 m up the ramp, stops, and…
A block attached to a spring oscillates in simple harmonic motion along the x-axis between the two extremes, x = 10 cm and x = 30 cm. The block goes from one extreme to the other in 0.25 s. Its amplitude and frequency are:
I need my account canceled. I have tried to reply to the email that is sent to cancel the account, but nothing has happened. I need to canceled as soon as possible!

It is planned to have replaced 20 MW output from a fossil fuel power station with a 20 MW output solar-voltaic power station. If the average solar insolation (power incident normally per square metre on the surface of the Earth) at a given location is 350 W m-2, and the efficiency of the…
Two identical balls, A and B, are released from rest from the same height, 2.8 m, along two smooth inclined planes that touch the horizontal ground. Ball A is released on a plane inclined at 300 to the horizontal. The plane on which ball B is released is inclined at 600 to the horizontal.…
What do you know about the force that causes the two blocks to separate after approximately 1.0 second?
How much mass would a black hole contain if it has an event horizon equal in size to an average sized tennis ball? Express your first answer, using scientific (powers of ten) notation, in kg and also express the same answer in units of “Earth masses.
What would be the diameter (of the event horizon) of a black hole with the same mass as Jupiter?
Below is depicted a block on a frictionless surface. It is attached by a spring to a wall. The unstretched length of the spring is 1.00 m. The spring is stretched so that its length as depicted in the diagram is 1.20 m. Because of the spring, the block is accelerating rightward at 2.3 m/s2.…
The potential energy U in Joule of a particle of mass is 4kg moving in the x-y plane is given by the formula U = 6x + 8y + 5. Here x and y are coordinates of the particle in meter. The particle is at (3,5) at t = 0 and v 0 = 0. i and jare the unit vectors across x and y…
The contraction of the left ventricle (chamber) of the heart pumps blood to the body. Assuming that the inner surface of the left ventricle has an area of and the maximum pressure in the blood is 120 mm-Hg, estimate the force exerted by that ventricle at maximum pressure.
