If a 15-ohm resistor is connected in parallel with a 30 ohm-resistor, the equivalent resistance is?
Bad White [126]

Answer:

Explanation:

in parallel combination equivalent resistence =

1/R=1/R1 + 1/R2

1/2=1/15+1/30

1/2=1*2+1*1/30

1/R=3/30

R*3=30*1

R=30/3

R=10 ohm

Lauryn serves a volleyball with a mass of 2.1 kg. The ball leaves her hand with a speed of 30 m/s.
Naya [18.7K]

Hi! Let's see.

<h3><u>TOPIC: Kinetic Energy.</u></h3>

Explanation:

Data:

  • Mass(m) = 2.1 kilograms
  • Speed(v) = 30 m/s
  • Kinetic Energy(Ek) = ?

==================================================================

Use the kinetic energy formula:

  • \boxed{\boxed{\bold{E_{k}=\frac{m*(v)^{2}}{2}}}}

Replace by the data:

  • \boxed{E_{k}=\frac{2.1kg*(30\frac{m}{s})^{2}}{2}}}}}

We multiply speed squared:

  • \boxed{E_{k}=\frac{2.1kg*900\frac{m}{s}}{2}}}

Multiply in the numerator, without forgetting the units:

  • \boxed{E_{k}=\frac{1890J}{2}}}}

Both numerator and denominador operations are divided:

  • \boxed{\bold{E_{k}=945\ J}}

Answer: The kinetic energy is <u>945 Joules.</u>
