The current required by the 60W bulb is three-fifths that required by the 110W bulb

<h3>Electrical Power</h3>
  • Electrical power is defined as the amount of electrical work done per second
  • Power = electrical work done in joules/time taken in seconds

The formula for calculating power is as follows:

  • P = IV = V²/R = I²R

Assuming the voltage across the light bulbs is the same

From the formula, P = IV;

I = P/V

For the 60 W bulb

I₁ = 60/V

For the 100W bulb

I₂ = 100/V

Taking ratios of the currents:

I₁/I₂ = {60/V}/{`100/V}

I₁/I₂ = 3/5

Therefore, the current required by the 60W bulb is three-fifths that required by the 110W bulb

Margaret [11]

Answer:

The speed of the piñata immediately after being cracked by the stick is v_{fp}=0.59\: m/s.

Explanation:

Using the conservation of linear momentum:

m_{s}v_{is}=m_{p}v_{fp} (1)

Here:

m(s) is the mass of the stick

m(p) is the mass of the piñata

v(is) is the initial velocity of the stick

v(fp) is the final velocity of the piñata        

So, we just need to solve the equation (1) to v(fp).

v_{fp}=\frac{m_{s}v_{is}}{m_{p}}

v_{fp}=\frac{0.54*4.8}{4.4}

v_{fp}=0.59\: m/s

I hope it helps you!
