it's not to scale, but that's your model... now you use Pythagorean Theorem
x^2+160^2=90^2
x^2=-17500
x=the square root of -17500

How do the hands on a clock turn?
They are turned by a gear train, which in turn is driven by a spring-driven, weight-driven, or electric motor. Their direction of rotation is normally clockwise when viewing the clock's "face".
How many miles traveled while driving 45 miles per hour?
If you drive for an hour, you have driven 45 miles. If you have driven for a longer or shorter time, you have driven more or less, respectively. You have to specify the amount of time to get the answer.
What does TDD mean?

What is mean by clock driven approach?
Clock-driven (time-driven) schedulers - Scheduling decisions are made at specific time instants, which are typically chosen a priori. • Priority-driven schedulers - Scheduling decisions are made when particular events in the system occur, e.g. • a job becomes available • processor becomes idle - Work-conserving: processor is busy whenever there is work to be done.
What is the Hiley formula?
A formula that is used fir driven piles
Magnitude of displacement between Delhi and Bhubaneswar if the distance driven is 1850 km and actual road distance is 1745 km?
Around 500
A car is driven 12 km west then after a 90 degree turn drove 5 km south What is the magnitude of the displacement?
13 km South 67 degrees West
Why do tornadoes travel southwest to northeast?
That is the direction most storms in the temperate parts of the northern hemisphere travel, driven by the prevailing winds.
What the diffence of displacement and non-displacement pile?
A displacement pile is one which displaces soils during installation. For instance a driven pile displaces the soil as it is being driven into the ground. A non-displacement pile is one formed by some other method, perhaps a drilled shaft, or some other installation method.
How do the magnitude direction and point of application of force affect a nail being driven into a piece of wood with a hammer?
If a nail is not hit square on the top by the hammer it will bend and there is a likelihood that the wood will be damaged by hammer marks or the bent nail.
A car is driven 215 km west and then 85 km southwest. What is the displacement of the car from the point of origin magnitude and direction draw a diagram.?
To solve this problem, I must explain the concept of vectors. Vectors merely consist of a magnitude and a direction. For this type of problem, the magnitude is the distance the car travels. Imagine arrows that are pointed in the direction of movement, and the same distance as the car moves. In this case, we will say that north is zero degrees. We know that since the car travels 215 km west, the first displacement is 215 west, and this is easy to visualize exactly where the car is. However, since the 85 km displacement is diagonal, it is more difficult to determine where exactly the vector goes. We must break this into components, in other words, two separate vectors. We must find out how far the car moves in the north-south direction, and how far it moves in an east-west direction. We do this using trigonometry. When we assumed that north is zero degrees, we determine that southwest corresponds to -135 degrees. So the calculations go as follows. For the east-west component, 85cos(-135)=-60.104 km. This means that the displacement from this vector is 60.104 km west. For the north-south component, 85sin(-135)= -60.104 km. This means that the displacement for this vector is 60.104 km south. We then add these two vectors to the 215km west. 215km + 60.104km = 275.104km. This means that the car has traveled a total of 275.104 km west. Since the car didn't travel south initally, we can just say that the car traveled 60.104 km south. To find out the straightline distance that this displacement is from the start, we use the pythagreaon theorem. The west and south displacements make up the legs of a right triangle. By adding the squares of these displacements, then taking the square root of the sum, we get 281.593 km from the start point. To get the angle of this displacement, use the inverse tangent function of the north-south component divided by the east-west component. We get 12.32 degrees. We must add this to the 90 degrees we get from the west component, so in the end, the vector can be defined as 281.593 km, -102.32 degrees. Hope this helps.
Why Is the magnitude of instantaneous velocity always equal to the instantaneous speed?
Yes, it can be. Average speed is the distance traveled divided by the time traveled. Average velocity is the displacement divided by the time traveled. Displacement is change in position, or final position (df) minus initial position (di). Let's say you traveled from your home to the mall and then back again. The total distance traveled was 30 miles, and the total time driven was 1 hour. Average speed = distance traveled/time traveled = 30 miles/1 hour = 30mi/hr or 30mph. Average velocity = (df - di)/time traveled = 0 mile/1 hour = 0 mi/hr or 0mph.* *In this case the final position and the initial position are the same (your house), so the displacement is zero. Something to think about: When a Nascar driver races 500 miles around an oval track, his average speed might be 160mph, but his average velocity when he finishes the race is 0mph.
How does the gear drive differ from the chain drive in regard to direction of rotation of the wheels?
With a chain drive the driven wheel will always rotate in the same direction as the drive wheel, but in a gear drive the direction of rotation will change between drive wheel and driven wheel.
What is a idler gear?
It changes the direction of movement in a gear system, so that the driver and driven gears move in the same direction.
How do the hands on a clock turn?
They are turned by a gear train, which in turn is driven by a spring-driven, weight-driven, or electric motor. Their direction of rotation is normally clockwise when viewing the clock's "face".
What direction does the fan rotate on a Chevy 305?
V-belt driven, clockwise.
How much fuel does a vehicle use per hour?
That depends on 1) the type and make of vehicle 2) how it is driven 3) the speed at which it is being driven 4) the wind speed and direction as compared to the vehicle's direction of travel. As you have not told us these things we can not be more helpful.
