While riding in a hot air balloon, which is steadily decreasing at a speed of 1.14 m/s, you accidentally drop your cell phone. H

Ilia_Sergeevich [38]

Answer:

The distance covered by the balloon is 47.52 meters.

Explanation:

Given that,

Initial speed of the balloon, u = 1.14 m/

Let us assumed we need to find the distance covered by the balloon after t = 3 second. Let d is the distance covered by the balloon. It can be given by :

$d=ut+\dfrac{1}{2}at^2$

Here, a = g

$d=ut+\dfrac{1}{2}gt^2$

$d=1.14\times 3+\dfrac{1}{2}\times 9.8\times (3)^2$

d = 47.52 meters

So, the distance covered by the balloon is 47.52 meters. Hence, this is the required solution.

dimaraw [331]

E=Fe/q
5.8x10^5N/C=Fe/(1.5x10^-9C)
Fe=(5.8x10^5N/C)(1.5x10^-9C)
Fe=8.7x10^-4N

Fe=kq1q2/r²
8.7X10^-4N=(8.99x10^9N·m²/C²)(1.5x10^-9C)(1.5x10-9C)/r²
r²=(8.99x10^9N·m²/C²)(1.5x10^-9C)(1.5x10-9C)/(8.7x10^-4N)
√r²=√0.00002325
The final answer is r=4.8x10-3m

How long in seconds will it take a car traveling at 100 miles/hour to travel the length of an American Football field?

Mrrafil [7]

Answer:

It will take 2.45 seconds.

Explanation:

A football field measured 120 yards, that is arround 0.068 miles, the car is moving with a constant speed so the formula we have to apply for this is:

$t=\frac{x}{v}\\where\\x=distance\\v=speed\\$

$t=\frac{0.068}{100}\\t=0.00068hrs$

in order to obtain the time in seconds:

$tsec=0.00068hr*(\frac{3600sec}{1hr} )\\tsec=2.45 sec$
