Answer:
0.13 seconds
Explanation:
Since 1 Km = 0.621 miles
3.84 x 105 km = 3.84 x 105 × 0.621 = 23846.4 miles
Speed = distance/time
time= distance/speed
Time= 23846.4/186,000
Time= 0.13 seconds
Answer is given below
Explanation:
given data
pressure = double
volume = constant
solution
As we know that an Average velocity and rms velocity is directly proportional to square root of PV ..................1
so if we take P is doubled while keeping V constant
than Velocity increases by a factor 
so that Factor = 1.414 for both the cases

Explanation:
Answer:
a) For the passenger the ball is seen to go up in a straight line path, and fall back to the hands of the passenger in a straight line path.
b) For a stationary observer on the ground, the ball is seen to take a parabolic path from when it is thrown up to when it fall down back on the palms of the passenger.
Explanation:
If a ball is thrown up in a vehicle moving with a constant velocity, the ball will be seen as the passenger, who is on the same frame of reference as the ball, to go up and down in a vertical straight line path. For an observer on the ground, this is different, as the ball is seen to to have both a relative vertical and horizontal component of motion, making the ball take a parabolic path from the time it was thrown, to when it falls back to the hands of the passenger.
Explanation:
It is given that, a batter hits a pop-up to a fielder 93 m away, range of the projectile, R = 93 m
The ball remains in the air for 5.4 s, the time of flight is 5.4 s
Time of flight : 
Maximum height of the projectile : 
We need to find H.
So,
So, it will rise to a height of 35.72 m.
