How long would the Suns initial supply of hydrogen last in both seconds and yrs as it fuses 600 bil. k ea. second total H avail. in its lifetime is 1.8x10 to 2nd pwr?

You are supposed to divide the total amount of hydrogen, by the consumption per second. That will give you the time in seconds. You can then convert that to years, by dividing by the number of seconds in a year.

Ignoring air resistance a rock in free fall will have a velocity of what after 4 seconds?
The final velocity is simply acceleration x time. The distance can be calculated from: d = 1/2 acceleration time squared + (initial speed) x time Since the initial speed is assume to be zero, you can simply ignore the second term. The acceleration due to gravity is approximately 9.8 meters per second squared.
Convert 300 milliseconds to seconds?
There are 1000 milliseconds in a second, so 300 milliseconds is 300/1000 or 0.3 seconds.
How many nano seconds in a second?
There are 31,536,000,000,000,000 nano seconds in a year.
If a shoe is dropped from a height of 40m what is its speed after falling for two seconds?
Regardless of the height from which it is falling, (neglecting air resistance) it's speed will be 19.62 metres per second. (Acceleration from gravity is 9.81 metres per second squared, so after 1 second it is moving at 9.81 metres per second and after 2 seconds it is moving at 19.62 metres per second.
What is the velocity after three seconds when a force of 25 newtons acts on a 10 kg body at rest?
25 N acting on 10 kg increases the velocity by 25/10 metres per second, every second, so after 3 seconds the speed is 7.5 metres per second.
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
A car having an initial speed of 16 meters per second is uniformly brought to rest in 4.0 seconds How far does the car travel in this 4.0-second interval?
The answer is 32 meters

If a planes initial speed is 0 meters per second and is accelerated at 15 meters per second squared what is its speed for 0-10?
The plane's velocity at 10 seconds will be 150 meters per second or 335.54 mph
How far will you travel in 30 seconds accelerating from rest at 1 meter per second per second?
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
A piece of metal has attained a velocity of 107.8 meters per second after falling for ten seconds what is its initial velocity?
the answer is 24-9 m/sec. yuor welcome
How many second in a average lifetime?
well so many people live to so many different ages, but there are 1 billion seconds in 33 years so multiply that

A ball thrown vertically upward returns to the starting point in 8 seconds.find its initial velocity.?
A ball thrown vertically upward returns to the starting point in 8 seconds.-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by(9.8 meters/second2) x (4 seconds) = 39.2 meters per second-- So that had to be the magnitude of its initial upward velocity.
