Explain why it is not advisable for soldiers to march across the bridge in rythm​

At a certain point, the bridge would start oscillating to the same rhythm as that of the marching steps. This oscillation would reach a maximum peak when the bridge can no longer sustain its own strength and hence collapses. Therefore, soldiers are ordered to break their steps while crossing a bridge.

xz_007 [3.2K]

Answer:

a. Technician A

Explanation:

Technician A says that a MAF sensor is a high-authority sensor and is responsible for determining the fuel needs of the engine based on the measured amount of air entering the engine. Technician B says that a cold wire MAF sensor uses the electronics in the sensor itself to heat a wire 20°C below the temperature of the air entering the engine. Who is right

MAF wich stands for  mass airflow sensor determines the mass of air flowing into the engine's air intake system. ... , the wire cools When air flows past the wire, decreasing its resistance, thereby more current flows through the circuit. When the MAf goes bad, it can not sense the amount of air intake into the engine.

1. They have evolved their leaves into spikes for minimum water loss through transpiration.

2. They have a waxy layer for minimum water loss.

3. They have thick walls for minimum water loss.

4. They can take water from atmosphere.

5. They change the photo energy from Sun into an intermediate stage and store it, so that they can make food even in night.

John travels 250 miles North, but then 105 miles South to pick up a friend. What is his total distance and displacement? 355 mil
bazaltina [42]

Answer:

The displacement is 145 m in the north direction and the distance is 355 miles.

Explanation:

The distance traveled by a mobile is the length of its trajectory and it is a scalar quantity. In other words, distance refers to the space traveled by an object during its movement. It is calculated as the sum of all the distances traveled. In this case:

250 miles + 105 miles= 355 miles

On the other hand, displacement refers to the distance from a start position to an end position regardless of the travel. That is, like distance, displacement is a measure of length. Instead, the displacement is a vector quantity that depends on the direction, so it is described from the magnitude and the direction.

Mathematically, the displacement d is calculated as:

d = df - di

where df is the final position and di is the initial position of the object.

In this case:

displacement= 250 miles - 105 miles= 145 miles

Since the north distance is greater than the south distance, then <u><em>the displacement is 145 m in the north direction and the distance is 355 miles.</em></u>
