Does the Voltage varies throughout a series circuit?

Physics
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

Explanation:

Short answer yes.

Suppose

R1 = 20 ohms

R2 = 30 ohms

R3 = 50 ohms

They are all connected in series and hooked to a 100v DC source.

The voltage across the 20 30 and 50 volt resistors will all be different.

If you mean can the 100v source vary. The answer to that is also yes, but a good steady output is usually what the manufactures come up with.

The speed of an object is given by v = 5.00t^2 + 4.00t where v is in m/s and t is in s. What is the acceleration of the object a
nexus9112 [7]
The speed is 
v = 5t² + 4t
where 
v is in m/s, and t in s.

The acceleration is the derivative of the velocity. It is
a = 10t + 4

When t = 2 s, the acceleration is
a(2) = 10*2 +4 = 24 m/s²

Answer: 24 m/s²

At this output power, how long would it take an 89 kg cyclist (including the mass of his bike) to climb the famed 1100-m-high al
Artemon [7]
<span>In general the route that follows the 1100-m-high alpe d'huez mountain stage takes anywhere from four to six hours in athletes from around the world. A beginner would probably take 8 hours or so. World records were recently broken with a time just under three hours. The most friction for cyclist is the competition itself.</span>

A body is thrown up with a velocity of 78.4 m per second.How high will it rise and how much time it will take to return to its p
a_sh-v [17]

Answer:

The maximum height reached by the body is 313.6 m

The time to return to its point of projection is 8 s.

Explanation:

Given;

initial velocity of the body, u = 78.4 m/s

at maximum height (h) the final velocity of the body (v) = 0

The following equation is applied to determine the maximum height reached by the body;

v² = u² - 2gh

0 = u² - 2gh

2gh = u²

h = u²/2g

h = (78.4²) / (2 x 9.8)

h = 313.6 m

The time to return to its point of projection is calculated as follows;

at maximum height, the final velocity becomes the initial velocity = 0

h = v + ¹/₂gt²

h = 0 + ¹/₂gt²

h =  ¹/₂gt²

2h = gt²

t² = 2h/g

t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 313.6}{9.8} }\\\\t = 8 \ s
