What is Ohm's Law, and how does it work in real life.

Physics
1 answer:
Firdavs [7]3 years ago
8 0

Explanation:

Ohms law states that the electrical current present in a metallic conductor is directly proportional to the potential difference between the metallic conductor and inversely proportional to the resistance therefore if the voltage is increased resistance also increases provided that temperature and other physical properties remains constant V=IR

Which of the following layers in Uranus’ atmosphere is the densest part? Stratosphere Troposphere Thermosphere Uranus does not h
VLD [36.1K]

Answer: Troposphere

Explanation:

Fairly over the "surface" of Uranus lies the troposphere, where the atmosphere is the densest. The temperature ranges from a minus 243 degrees Fahrenheit (minus 153 degrees Celsius) to minus 370 F (minus 218 C) , with the upper regions being the coldest. This makes the atmosphere of Uranus the coldest within the solar system. Inside the troposphere are layers of clouds — water clouds at the least weights, with ammonium hydro sulfide clouds over them. Alkali and hydrogen sulfide clouds come following. At long last, lean methane clouds lay on the best. The troposphere amplifies 30 miles (50 kilometers) from the surface of the planet.

Using this information, we can determine that the Troposphere is the densest layer of Uranus's atmosphere.

A ball is projected 203 meters straight upward and then falls the same distance back to its starting point.
Jet001 [13]

Answer:

12.88 s

Explanation:

We can solve this problem by considering only the first half the motion, from the moment the ball is projected upward to the moment it reaches its maximum height.

Since this is a uniformly accelerated motion, we can use the following suvat equation:

s=vt-\frac{1}{2}at^2

where:

s is the vertical displacement

v is the final velocity

t is the time

a is the acceleration

Here we have:

v = 0: the vertical velocity is zero when the ball has reached its maximum height, that is

s = 203 m

a=g=-9.8 m/s^2 (acceleration of gravity, negative because it is downward)

Solving the equation for t, we find the time at which the ball reaches the maximum height:

t=\sqrt{-\frac{2s}{a}}=\sqrt{-\frac{2(203)}{-9.8}}=6.44 s

The second half of the motion is symmetrical and identical to the first one, so the total time in air is just twice this time, therefore:

T=2t=2(6.44)=12.88 s

Consider two spaceships, each traveling at 0.50c in a straight line. Ship A is moving directly away from the Sun and ship B is a
attashe74 [19]

Answer:

The velocity of the light will be 1.0c only

Explanation:

The velocity of the light measured in the case given in question will be 1.0c only.

This is due to the fact that the velocity of light is never relative. The velocity of the light is maximum

The velocity of the light cannot be scaled down in no case

Thus, the velocity of the light remains as constant.

Hence, the velocity of the light measured will be 1.0c although the ships have relative velocity.
