Answer:

1 Ohm is defined as the resistance of a conductor with a potential difference of 1 volt applied to the ends through which 1-ampere current flows. Ohms is the SI unit of electrical resistance

Explain why it is not advisable to use small values of index in performing refraction through a prism experiment

horsena [70]

The refractive index is the ratio of the speed in a vacuum to the speed of light in the given medium. If the refractive index is too low, there will not be a large bending, or deviation, of the light beam from its original path.

The small deviation will make it difficult to carry out the experiment, and is more likely to cause errors. Therefore, larger refractive indexes should be used, in order to ensure that the bending of the light beams is easily traceable.

Give me advantages and disadvantages of sustainable energy:

AVprozaik [17]

An advantage of sustainable energy is that it diversifies the energy supply and reduces importance on imported fuels.
A disadvantage is that all types of gaining access to sustainable energy requires a lot of space/ land. This may prevent important necessities such as housing to not have enough land. Hope this helps ;)

Please answer the question for gravitational field attached in the image.

goblinko [34]

We are given:

Radius of Venus= 6 * 10⁶ m

Height above the planet's ground = 9.4 * 10⁶ m

Mass of Venus = 4.867 * 10²⁴ kg

Finding the Gravitational Field:

We first need to calculate the distance between the center of masses

Distance between center of masses:

Since the point is above the surface of Venus, the radius of Venus and the height will add

Distance between the center of masses = 9.4*10⁶ + 6 * 10⁶

Distance (r) = 15.4 * 10⁶ m

Now back to Gravitational field!

We know the formula for Gravitational Field:

g = GM / r² [where g is the gravitational field, M is the mass of the planet, r is the distance between the center of masses and G is the gravitational constant]

plugging the known values in the formula:

g = (6.67 * 10⁻¹¹ * 4.867 * 10²⁴) / (15.4*10⁶)² [G = 6.67*10⁻¹¹ Nm²/kg²]

g = (32.46 * 10¹³) / (237 * 10¹²)

g = (32.46 * 10¹³) / (23.7 * 10¹³)

g = 32.46/23.7 [the 10¹³ got cancelled out]

g = 1.367 N/kg² (or m/s²)
