ZE and ZF are vertical angles with mZE= 9x + 12 and mZF= 3x + 24. What is the value of x?

Answer:

x=2

Step-by-step explanation:

Vertical angles are equal

m ZE = m ZF

9x+12 = 3x+24

Subtract 3x from each side

9x -3x +12 = 3x-3x+24

6x+12 = 24

Subtract 12 from each side

6x+12 -12 = 24-12

6x = 12

Divide each side by 6

6x/6 =12/6

x = 2

A constant force acts on a 30-g object and produces an acceleration of 2 m/s2. Find the force in dynes.
FinnZ [79.3K]

Answer:

Force      F = 60 ×10⁻⁵ N

Step-by-step explanation:

Given that mass of the given object (m)  = 30 grams

Given that the acceleration

                                 a = 2 m/s²

<u><em>Force:-</em></u>

The push or pull on an object with mass that causes it to change its velocity

  • Force can make a body that is rest to move
  • it can accelerate the speed of a moving body

<u><em>Formula for force</em></u>

The formula for force    F = m a

                                      F = 30 × 2

                                     F  = 60 gm/s²

                                   F = 60 ×10⁻⁵ N     (∵ 1 d y n = 1gm² = 10⁻⁵N
