The answer is B. Both NPN and PNP transistors consist of a base composed of an N-type material.
Answer:
The energy that the truck lose to air resistance per hour is 87.47MJ
Explanation:
To solve this exercise it is necessary to compile the concepts of kinetic energy because of the drag force given in aerodynamic bodies. According to the theory we know that the drag force is defined by
Our values are:
Replacing,
We need calculate now the energy lost through a time T, then,
But we know that d is equal to
Where
v is the velocity and t the time. However the time is given in seconds but for this problem we need the time in hours, so,
(per hour)
Therefore the energy that the truck lose to air resistance per hour is 87.47MJ
<span>If the forces are acting in exactly opposite directions, they will subtract, and the magnitude of the resultant force is 6 N. This is the minimum resultant force, so that rules out (1). Similarly, if they act in exactly the same direction, they will add, and the resultant force is 18 N. This will be the maximum resultant force. That rules out (3) and (4). Thus, at some angle (between 0 and 180 degrees), you COULD find a resultant force of 15 N.</span>

Answer:
Gemini
Explanation:
Zodiac Constellation or Sun sign is the constellation in which the Sun resides on the date of birth of a person. Throughout the year the Sun crosses across 12 constellations thus there are 12 Sun-signs. Though astronomically the Sun crosses across 13 constellations so there should be 13 zodiacs but most of the astrologers do not accept this. On the date of June 20, the Sagittarius which is a summer constellation and a zodiac can be seen high up in the sky in the night time. At this time the Sun will be in a constellation which is almost opposite to Sagittarius in the celestial sphere. That constellation is Gemini. Thus for a person born on 20 June, zodiac will be Gemini.
