\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}

An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. ... In the absence of any forces, no force is required to keep an object moving.

The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. In a labor
Travka [436]

Answer:

F  = 183.153 N

Explanation:

given,

mass of the toothpick = 0.12 g = 0.00012 kg  

initial velocity = 227 m/s    

final velocity = 0 m/s      

penetration depth = 16 mm = 0.016 m        

using the equation of motion        

v² - u² = 2 a s                            

0 - u² = 2 a s                                      

- 221² = 2 × a × 0.016      

a = 1526281.25 m/s²            

Force is equal to            

F = m a

  = 0.00012 × 1526281.25

F  = 183.153 N

What happens when solar energy heats a body of water?
Nataliya [291]
Explanation: Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor (Dunn,1993).

A circuit contains four capacitors in parallel (10 F, 3 F, 7 F, and 1 F). What is the equivalent capacitance of this circuit?
Oxana [17]

The equivalent capacitance (C_{eq}) of an electrical circuit containing four capacitors which are connected in parallel is equal to: A. 21 F.

<h3>The types of circuit.</h3>

Basically, the components of an electrical circuit can be connected or arranged in two forms and these are;

  • Series circuit
  • Parallel circuit

<h3>What is a parallel circuit?</h3>

A parallel circuit can be defined as an electrical circuit with the same potential difference (voltage) across its terminals. This ultimately implies that, the equivalent capacitance (C_{eq}) of two (2) capacitors which are connected in parallel is equal to the sum of the individual (each) capacitances.

Mathematically, the equivalent capacitance (C_{eq}) of an electrical circuit containing four capacitors which are connected in parallel is given by this formula:

Ceq = C₁ + C₂ + C₃ + C₄

Substituting the given parameters into the formula, we have;

Ceq = 10 F + 3 F + 7 F + 1 F

Equivalent capacitance, Ceq = 21 F.
