Does the same battery always deliver the same amount of flow to any circuit? Mention two observations of any circuits in this la

b that support your answer. Explain.
Physics

V125BC [204]3 years ago
6 0

Answer:

Yes

Explanation:

Given that the battery is the same the PD ( potential difference ) in the circuit will also be the same likewise the flow of charge in the circuit,

Hence the same amount of charge flow is delivered to any circuit.

attached below are examples

svet-max [94.6K]

Answer:

v=38.73m/s

Explanation:

u=15m/s

v =?

s=65m

g=9.81

v²=u²+2×g×s

v²=15²+2×9.81×65=1500.3

v=38.73m/s

How is the direction of light changed when it travels from an optically denser medium to an optically rarer medium????? please a
ANTONII [103]

Answer:

The light bends away from the normal

Explanation:

We can solve the problem by using Snell's law:

n_1 sin \theta_1 = n_2 sin \theta_2

where:

n_1 is the index of refraction of the first medium

n_2 is the index of refraction of the second medium

\theta_1 is the angle of incidence (angle between the incoming ray and the normal to the interface)

\theta_2 is the angle of refraction (angle between the outcoming ray and the normal to the interface)

We can rearrange the equation as

sin \theta_2 = \frac{n_1}{n_2}sin \theta_1

In this problem, light travels from an optically denser medium to an optically rarer medium, so

n_1 > n_2

Therefore, the term \frac{n_1}{n_2} is greater than 1, so

sin \theta_2 > sin \theta_1\\\rightarrow \theta_2 > \theta_1

which means that the angle of refraction is greater than the angle of incidence, and so the light will bend away from the normal.

Justin, with a mass of 30 g, is going down a 8.0 m high water slide. he starts at rest, and his speed at the bottom is 11 m/s. h
mr Goodwill [35]
<span>The thermal energy is the work done by friction. If Justin is at rest intially, his potential energy is MGH. Hence we have 30* 9.8*8 = 2352N. Where m is mass, g accleration due to gravity, and h is the height. When he gets to the bottom of the slide, his potential energy is converted to usable kinetic energy, so we have 1/2 mv^2. We end up with 1/2 * 30 * (11)^2 = 1815N. He started with 2352N and ended up with 1815N. Hence the thermal energy is 2352 - 1815 = 537N.</span>
