Helen [10]

Answer:

P = 0.25 W

Explanation:

Given that,

The emf of the battry, E = 2 V

The resistance of a bulb, R = 16 ohms

We need to find the power delivered to the bulb. We know that, the formula for the power delivered is given by :

P=\dfrac{V^2}{R}\\\\P=\dfrac{2^2}{16}\\\\=0.25\ W

So, 0.25 W power is delivered to the bulb.

If the soccer ball has a mass of 284g, and gravitational force is 9.81 m/s2 on Earth, what is the weight of the soccer ball?
bagirrra123 [75]

Answer:

  1. <u>2.79 N</u>
  2. <u>8.34 N</u>
  3. <u>Watermelon</u>

Explanation:

<u>Weight of soccer ball</u>

  • Weight = mass (in kg) × gravitational force
  • Weight = 284 x 10⁻³ x 9.81
  • Weight = 0.284 x 9.81
  • Weight = <u>2.79 N</u> (approximately)

<u>Weight of watermelon</u>

  • Weight = mass (in kg) x gravitational force
  • Weight = 850 x 10⁻³ x 9.81
  • Weight = 0.85 x 9.81
  • Weight = <u>8.34 N</u> (approximately)

As the <u>watermelon</u> has more weight, it will hit the ground first.
