Wood Wall Framing

Draw out the wood framing you would propose for each of the three wall elevations presented below. 

A roller-coaster car has a mass of 920kg when fully loaded withpassengers. As the car passes over thetop of a circular hill ofradius 15 m,its speed is not changing.

What are the magnitude and direction of the force of the trackonthe car at the top of the hill if the car's speed is 16m/s?

I'm getting -6685N . But I keep getting it wrong.

A roller coaster vehicle has a mass of 500kg when fully loaded withpassengers. if the vehicle has a speed of 20.0 m/s at point A, whatis the force exerted by the track on the vehicle at this point?what is the max speed the vehicle can have at B and still remain onthe track

Which of the following is not true about Antonin Dvorak?

A. He began his music career as an organist.

B. He was not influenced by a deep sense of nationalism.

C. He impressed composer Johannes Brahms, who was one of the judges of a musical contest he entered.

A roller-coaster vehicle has a mass of 500 kg when fully loaded with passengers (Fig. P7.28). r1 = 7 m and r2 = 25 m (a) If the vehicle has a speed of 18 m/s at A, what is the magnitude of the force that the track exerts on the vehicle at this point? What is the maximum speed the vehicle can have at B in order for gravity to hold it on the track?

A roller-coaster car(FigP6.16) has a mass of 500 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and-down motion (as seen by the riders),with no motion to the left or right.(a) If the vehicle has a speed of 20.0 m/s at point A, what is the force exerted by the track on the car at this point?(b) what is the maximum speed the vehicle can have at point B and still remain on the track? Assume the roller-coaster tracks at points A and B are parts of vertical circles of radiusr=10.0m and r= 15.0m

Why wavefront is always perpendicular to the direction propagation of wave?

a. find a price of Bond A, a 1-year zero-coupon bond, which has a return of 6.6% and a face value of $1000. Show calculations and formula.

b. would you prefer Bond A to Bond B, a 1-year zero coupon bond which sells for $ 910 and has a face value of $1000, show and explain.

c. would you prefer Bond A , Bond B or Bond C is a 1-year zero coupon bond with face value of $500 and sells for $470, show and explain

A)

A sample of a gas is in a sealed container. The pressure of the gas is 365 torr , and the temperature is 20 ∘C . If the temperature changes to 63 ∘C with no change in volume or amount of gas, what is the new pressure, P2, of the gas inside the container?

Express your answer with the appropriate units.

B) Using the same sample of gas (P1 = 365 torr , T1 = 20 ∘C ), we wish to change the pressure to 3650 torr with no accompanying change in volume or amount of gas. What temperature T2, in Celsius, is needed to reach this pressure?

Based on the Lewis structure for hydrogen and helium, explain why buoyant are filled with helium instead of hydrogen gas, even though gas is cheaper and more buoyant?
