Answer:
Many speculation exists for why the term 'scrubbed' is used in relation to launches. <em>One of these is that during world war II, when the Air force planned bombing raids</em>. These Air force missions had their briefings done with illustration of the details of the launch and and flight drawn on chalkboards. <em>When some of mission flight takeoffs were canceled (due to bad weather or a malfunction or other reasons) the details were then scrubbed off of the chalkboard</em>. This idea of the mission <em>being scrubbed meaning that it is no longer to be followed through with</em>, proceeded to this modern day rocket and aviation launches.
Answer:
Q = 8608.8 J
Explanation:
Given that,
The mass of ice, m = 34 g
The temperature changes from -2°C to 118°C.
The specific heat of ice, c = 2.11 J/g°C
The heat energy needed,
So, 8608.8 J of energy is needed.
It means that electric charge exists in integral multiples of an elementary unit of charge rather taking on continuous values.
Since Millikan was the first to measure the value of the electronic charge in his famous "oil drop" experiment, he may be the one given credit for discovering quantization of charge.
Answer:
Explanation:
Conventional current flows from cathode to anode. It is opposite to the direction of flow of electrons.
Answer:
Distance = 25000000 miles
Time = 50 hours
Explanation:
Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits
Given that
Speed V = 500000 mph
Distance d = 25 000,000 miles
Speed = distance/ time
Time = distance/speed
Time = 25000000/500000
Time = 50 hours
It will therefore take 50 hours to get to venus at that speed.
