A girl standing on a floor would have two opposite forces acting on it. These forces are the weight and the normal force. Since no other forces are acting and that the girl is at rest, then the weight must equate to the normal force. Therefore, the supporting force would be:

F = mg = 55kg (9.81 m/s^2) = 539.55 N

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>

The length of the adult mosquito is typically between 3.0 mm and 6.0 mm. The smallest known mosquitoes are around 2.5 mm, and th

FrozenT [24]

0.74in

Explanation:

Given parameters:

length range of adult mosquito = 3.0 - 6.0mm

Smallest mosquito = 2.5mm

Largest mosquito = 19mm

Average mass range = 3.0 - 5.0mg

Unknown:

Length of largest known mosquito in inches = ?

Solution;

The length is the longest dimension. It is how long a body is.

The problem here is converting from mm to inches;

The length of the longest mosquito which is the largest is 19mm

19mm to inches;

1mm = 0.039inches

19mm = 19mm x $\frac{0.039in}{1mm}$ = 0.74in
