Answer:

F = 27.22 N

Explanation:

Given that,

The length of the merry go round from center, R = 2.50 m

Tangential speed of the merry go round, v = 1.80 m/s

The mass of the dog, m = 21 Kg

The centripetal force is given by the formula,

                             F = mv² / R

Substituting the values in the above equation,

                             F = 21 Kg x (1.8 m/s)² / 2.50 m

                                = 27.22 N

Hence, the magnitude of the centripetal force on the dog, F = 27.22 N

LenaWriter [7]

Answer:

83.67 m/s

Explanation:

Set up a calculation to convert units of measure to what you need.

You have km/s and you need m/s.

4.08km     1000 m         83.67m

-----------  X ----------  =  ---------------   the km will cancel out and you are left

 12.0 s          1 km              s              with m/s

Please help I’m stuck
Gnoma [55]

The weight of the box is <em>w</em> = <em>mg</em>, where <em>m</em> is the mass. So

<em>m</em> = <em>w</em>/<em>g</em> = (3893.40 N) / (9.80 m/s²) ≈ 397 kg

Then the box has density

(397 kg)/(4.60 m³) ≈ 86.4 kg/m³

which is less than the density of the given liquid, so the box will float.

wariber [46]

Answer:

Alburt Bandura
