A wheelbarrow is being pushed with a force of 16 N, causing the wheelbarrow to move at a speed of 2 m/s. If the force changes to 10 N, what will happen to the speed of the
wheelbarrow?

The speed of the wheelbarrow wil decrease

The speed of the wheelbarrow will not be affected

The wheelbarrow will move at a constant speed of 2 m/s

The speed will increase to 5 m/s

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
