1 centimetres = 10 millimetres
178 centimetres = 10 × 178 = 1780 millimetres

First and second options are incorrect
------------------------------------------------------------------------------------------------------
1 metres = 100 centimetres
178 centimetres = 178 ÷ 100 = 1.78 metres

Third option is correct 
-----------------------------------------------------------------------------------------------------

1 cm = 10 mm
1 mm = 1000 micrometres
1 cm = 10000 micrometres
178 cm = 178 × 10⁴ micrometres

Fourth option is incorrect
-----------------------------------------------------------------------------------------------------

1 kilometre = 1000 metres
1 metre = 100 cm178 cm = 178 ÷ 100 = 1.78 metres
1.78 metres = 1.78÷1000 = 1.78 × 10⁻³ kilometres

Answer:

1 centimetres = 10 millimetres

178 centimetres = 10 × 178 = 1780 millimetres

1 meters = 100 centimeters

178 centimeters = 178 ÷ 100 = 1.78 meters Plato answer

1 cm = 10 mm

1 mm = 1000 micrometers

1 cm = 10000 micrometers

178 cm = 178 × 10⁴ micrometers

1 kilometre = 1000 metres

1 metre = 100 cm178 cm = 178 ÷ 100 = 1.78 metres

1.78 metres = 1.78÷1000 = 1.78 × 10⁻³ kilometres

A child lies on his back and raises his head up off the floor. When doing so, the total tension force in his neck muscles is 51.
Margarita [4]

Answer:

The total tension in the child's neck muscle, T = 56.51 N

Explanation:

Let m = mass of the child's neck

Radius of the curve, r = 2.40 m

The child's speed, v = 3.35 m/s

The tension force on the child's neck when he raises his head up off the floor, T_{f} = 51.0 N

The tension force on the child's neck when he raises his head from the wall of the slide, T_{s} = ?

T_{f} = mg\\g = 9.8 m/s^2\\51 = m * 9.8\\m = 51/9.8\\m = 5.2 kg

Since he makes a circular turn in water, the radial acceleration can be given by the equation:

a_{r} = \frac{v^{2} }{r} \\a_{r} = \frac{3.35^{2} }{2.4}\\a_{r} = 4.68 m/s^2

T_{s} = ma_{r} \\T_{s} = 5.2 * 4.68\\T_{s} = 24.336 N

The total tension in the child's neck muscle till be calculated as:

T = \sqrt{T_{f} ^{2} + T_{s} ^{2} } \\T = \sqrt{51 ^{2} + 24.336^{2} }\\T = \sqrt{2601 + 592.24 }\\T = 56.51 N
