What is one disadvantage of a series circuit?

Physics

If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺

oof, that question is difficult! i would say its d because if you pull a slingshot farther than another one, it would have more potential energy.

What is the term for the depth of the water needed to float a boat?
mina [271]
<span> The term for the depth of the water needed to make a boat afloat is called the draft of the boat. It can be measured as the distance from the water surface down the lowest point of the vessel. It can be imagined as the submerged portion of the boat during navigation.</span>

A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting?
aleksandrvk [35]
It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.

A typical human lens has an index of refraction of 1.430 . The lens has a double convex shape, but its curvature can be varied b
rjkz [21]

Answer:

Maximum Power = 144.3 D

The associated focal length of the lens = 6.92*10^{-3} m

Explanation:

According to the Lens maker's Formula:

\frac{1}{f} = (n-1) (\frac{1}{R_1}-\frac{1}{R_2}  )

where;

n_1 = the refractive index of the medium

R_1 and R_2 = radius of curvature on each surface

For a convex lens, The radius of curvature in the front surface will be positive and that of the second surface will be negative . Therefore;

\frac{1}{f} = (n-1) (\frac{1}{R_1}-\frac{1}{-R_2}  ) \\ \\ \frac{1}{f} = (n-1) (\frac{1}{R_1}+\frac{1}{R_2}  )

At maximum power

\frac{1}{f} = (1.430-1) (\frac{1}{6.50 \ mm}-\frac{1}{5.50 \ mm}  )

= 0.144 \ mm^{-1}

This Implies

f = 6.92 mm\\f = 6.92*10^{-3} \ m

Therefore; the power is given by the formula:

P_{max} = \frac{1}{f}

P_{max}= \frac{1}{6.92*10^{-3}}

= 144.3 D

Water flows through a garden hose which is attached to a nozzle. The water flows through hose with a speed of 1.81 m/s and throu
Serggg [28]

Answer:

a) 17.086m

b) 0.1671 m

Explanation:

Given data: speed of water through the hose  = 1.81 m/s

through the nozzle = 18.3 m/s

We know that maximum height of an object with upward velocity v is given by,

a) H = v^2/2g

where H is the maximum height water emerges  

= 18.3^2/(2×9.8) = 17.086 m answer

b) Again,  

H = v^2/2g

= 1.81^2/(2×9.8) = 0.1671 m
