When intending to pass another vehicle, you should activate the left turn signal at least 100 feet (200 feet if going over 40 mph) before executing passing maneuver , and allow the signal to flash at least times.

Three (3).

Explanation:

According to the transportation or traffic code, when intending to pass another vehicle, you should activate the left turn signal at least 100 feet (200 feet if going over 40 mph) before executing passing maneuver , and allow the signal to flash at least three (3) times.

This ultimately implies that, when a driver is about to overtake another vehicle (driver), it is mandatory or required by law that he or she activate the left turn signal (for a left-hand driven vehicle) at least 100 feet (200 feet if going over 40 mph), this is to make the intention to turn known to other road users and prevent any form of accidents in the process of executing the maneuver. Also, the turn lamp signal must be allowed to flash continuously for a minimum of three times.

if you tell me the video, i may be able to answer your question.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
