Hello!

A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?

Data:

We have six 1.5 volt batteries, soon, your tension (V)

V = 1.5 * 6 = 9 Volts

R (resistance) = 7.2 ohms

i (Current intensity) = ? (in Amps)  

Solving (Ohm's First Law):  

i = \dfrac{V}{R}

i = \dfrac{9}{7.2}

\boxed{\boxed{i = 1.25\:amps}}\end{array}}\qquad\checkmark

Note: If we consider the template by approximation, the answer would be:

\boxed{\boxed{\boxed{i\approx 1.3\:amps}}}

Answer:

B] 1.3 amps

The x and y components of the velocity vector is 17.32 m/s and 10 m/s respectively.

<h3>What is the x - component of the velocity?</h3>

The x-component of the ball's velocity is the velocity of the ball in the horizontal direction or x-axis.

The velocity of the ball in x-direction is calculated as follows;

Vx = V cosθ

where;

  • Vx is the horizontal velocity of the ball
  • V is the speed of the ball
  • θ is the angle of inclination of the speed

Vx = (20 m/s) x (cos 30)

Vx = 17.32 m/s

The velocity of the ball in y-direction is calculated as follows;

Vy = V sinθ

where;

  • Vy is the vertical velocity of the ball
  • V is the speed of the ball
  • θ is the angle of inclination of the speed

Vy = 20 m/s x sin(30)

Vy = 10 m/s
