Answer:

when the radius is halved, F becomes 4 times

Explanation:

<u><em>The formula is given by</em></u>

F = \frac{Gm1m2}{r^2}

<u><em>When r is halved:</em></u>

F = \frac{Gm1m2}{(1/2r)^2}

=> F = \frac{Gm1m2}{1/4 r^2}

=> F = 4(\frac{Gm1m2}{r^2} )

<u><em>This means when the radius is halved, F becomes 4 times</em></u>

Reika [66]

Answer:

1.7 seconds

Explanation:

To clear the intersection, the total distance to be covered = 59.7 + 25 =84.7m

first we need to find the initial speed to just enter the intersection by using the third equation of motion

v^2 - u^2 = 2*a*s

45^2 - u^2 = 2 * -5.7 * 84.7

u^2 = 45^2 +965.58

u^2 = 2990.58

u = 54.7 m/s

Now for time we apply the first equation of motion

v-u =a * t

t = (v-u)/a = (45 - 54.7)/-5.7 = 1.7seconds
