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 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.

Magnitude of displacement between Delhi and Bhubaneswar if the distance driven is 1850 km and actual road distance is 1745 km?
The magnitude of displacement between Delhi and Bhubaneswar can be calculated using the Pythagorean theorem. The displacement is the hypotenuse of a right triangle where the actual road distance is one side (1745 km) and the distance driven is the other side (1850 km). By applying the Pythagorean theorem (c^2 = a^2 + b^2), the magnitude of displacement is approximately 244.95 km.
A car is driven 12 km west then after a 90 degree turn drove 5 km south What is the magnitude of the displacement?
To find the displacement, we can use the Pythagorean theorem. The westward distance is 12 km, and the southward distance is 5 km, making a right triangle. The magnitude of the displacement is the hypotenuse of this triangle, which can be calculated as sqrt(12^2 + 5^2) = sqrt(144 + 25) = sqrt(169) = 13 km.
How do the magnitude direction and point of application of force affect a nail being driven into a piece of wood with a hammer?
The magnitude of the force determines how deep the nail will be driven into the wood. A greater force will drive the nail deeper. The direction of the force should be aligned with the nail to ensure efficient driving, and the point of application should be concentrated on the nail head to prevent it from bending.
Why do tornadoes travel southwest to northeast?
Tornadoes in the United States often travel from southwest to northeast due to the prevailing westerly winds that steer weather systems in that direction. These winds are commonly associated with weather patterns such as cold fronts and jet streams that can create the conditions conducive to tornado formation and movement in that direction.
How often do Monsoon winds change direction?
Monsoon winds typically change direction twice a year. In the Indian subcontinent, for example, the southwest monsoon generally brings rain from June to September, while the northeast monsoon brings dry weather from October to December. These seasonal changes in wind direction are driven by temperature differences between land and ocean.
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?
Instantaneous velocity is a vector quantity that includes both magnitude (speed) and direction. Since speed only considers magnitude and not the direction of motion, the magnitude of instantaneous velocity is always equal to the instantaneous speed at a specific point in time.
What the diffence of displacement and non-displacement pile?
Displacement piles displace soil and create a void during installation, which increases the lateral soil resistance. Non-displacement piles do not displace soil and rely on friction or end-bearing to transfer loads to the surrounding soil. Displacement piles are typically used in cohesive soils, while non-displacement piles are often used in granular soils.
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.
