-- Gravity adds 9.8 m/s to the downward speed of any object, every second ... as long as there are no other forces messing with it.
-- In 0.6 sec, gravity added (0.6x9.8)= 5.88 m/s to the downward speed of this ball.
-- This ball didn't start from zero. You threw it down with an initial speed of 1 m/s. So after 0.6 sec, with the help of gravity, its speed is
(1) + (5.88) = 6.88 m/s .
Pick choice-C .
Notice that we don't care how high it was off the ground when you threw it, just as long as it was high enough to keep falling for 0.6 sec without hitting the ground.
Answer:
Explanation:
A and B are touched .
charge on each of them after touching = (9q - q) / 2 = 4q
when C is touched with A
charge on A and C each after touching
= 4q + 0 / 2 = 2q
When C is touched with B
charge on each of them
(2q + 4q ) / 2 = 3 q
Final charge on C = 3q
Answer:
Using the Fundamental Equation of Wave, we have:
Explanation:
<h2>Greetings!</h2>
Firstly, to find speed you need to remember the speed formula:
Speed = Distance ÷ Time
You can do it by doing 2800 ÷ 2 but that gives m/h (metres per hour)
So to convert hours into seconds, you multiply 2 by 7200 (amount of second in 2 hours:
2 * 7200 = 14400 seconds
Now we can do distance ÷ time by plugging the values in:
2800 ÷ 14400 = 
≈0.194
<h3>So the average speed is 0.194m/s (metres per second) </h3><h3 /><h2>Hope this helps!</h2>
False, Gamma Rays are the smallest because gamma rays have the shortest wave length
