Which scenario will drain the battery in the circuit diagram fastest: three 20 W bulbs in positions one, two, and three or 80 W

bulbs at positions 1 and 3 with a gap at position two? How do you know?

Answer:

See the explanation below.

Explanation:

If you connect the three bulbs 20 W each will have a total power of 60W.

Now we need to understand to assign the meaning of the word gap, that is, if the circuit is open at that point or if there is no bulb connected at that point.

If the circuit is open at Point 2, there will be no current in the circuit, so the battery will drain faster with the three bulbs 20W.

In the second event, where gap means that there are no bulbs connected at that point, it means that you have two bulbs connected in series of 80W each.

In this case the bulbs will consume 160W thus drain the battery faster than the three 20W bulbs connected in series.

rickey approaches third base. He dives head first, hitting the ground at 6.75 m/s and reaching the base at 5.91 m/s in 2.5 secon
Gekata [30.6K]

Answer:

15.825 m

Explanation:

t = Time taken = 2.5 s

u = Initial velocity = 6.75 m/s

v = Final velocity = 5.91 m/s

s = Displacement

a = Acceleration

Equation of motion

v=u+at\\\Rightarrow a=\frac{v-u}{t}\\\Rightarrow a=\frac{5.91-6.75}{2.5}\\\Rightarrow a=-0.336\ m/s^2

v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{5.91^2-6.75^2}{2\times -0.336}\\\Rightarrow s=15.825\ m

The distance Rickey slides across the ground before touching the base is 15.825 m

If the coefficient of static friction at d is μd = 0.3, determine the smallest vertical force that can be applied tangentially t
const2013 [10]

Answer:

The minimum force is required is, f = 0.3 mg  Newton

Explanation:

Given data,

The coefficient of the static friction, μₓ = 0.3

Let the mass of the wheel is, m = M kg

The minimum force required to set the wheel in motion is equal to the force of static friction. This amount of force can be applied tangentially to the wheel in a vertical direction to set the wheel in motion.

                              <em> Fₓ = μₓ. F</em>

Where F is the normal force acting on the wheel and it is equal to mg.

Therefore, the minimum force is required is, f = 0.3 mg  Newton

LekaFEV [45]

<u>Answer:</u>

The correct answer option is C. buzzer.

<u>Explanation:</u>

We know that Jeff's father needs to get a device from his workshop that converts electrical energy to sound energy.

So from the given options, buzzer is the best option Jeff's father can install in his house's security system.

An electric buzzer converts an electrical oscillating voltage into a sound output. In other words, the electrical pulses are converted into sound vibrations.
