The diagram here shows an image being formed by a convex lens. Compared to the object at right, the image at left is-
natima [27]

Answer:

Smaller and upside down

Explanation:

To answer the question, we must recognise that the characteristics of the image formed by a convex lens depends on the position of the object from the lens.

From the diagram given in the question above, the following data were obtained:

1. The image is smaller than the object.

2. The image is inverted i.e upside down.

3. The image is closer to the lens

4. The image between 2f and f

Now, considering the options given in question above, the correct answer to the question is:

The image is smaller and upside down.

Estimate the acceleration due to gravity at the surface of Europa (one of the moons of Jupiter) given that its mass is 4.9×1022k
Taya2010 [7]

Answer:g=1.97 m/s^2

Explanation:

Given

mass of Jupiter is M=4.9\times 10^{22} kg

Density of Jupiter is same as Earth

density\ of\ Earth=density\ of\ Jupiter=5510 kg/m^3

mass=volume\times density

considering Jupiter to be sphere of radius r

M=\frac{4}{3}\times \pi r^3\times \rho

r^3=\frac{3M}{\rho \times 4\pi}

r^3=\frac{3\times 4.9\times 10^{22}}{5510\times 4\pi}

r=(\frac{3\times 4.9\times 10^{22}}{5510\times 4\pi})^{\frac{1}{3}}

r=1.28\times 10^6 m

acceleration due to gravity is given by

g=\frac{GM}{r^2}

g=\frac{6.67\times 10^{-11}\times 4.9\times 10^{22}}{(1.28\times 10^6)^2}

g=1.97 m/s^2

Describe differences in characteristics between the outer core and inner core?
ladessa [460]

This inner core is solid because it is pure iron, while the outer core has other impurities that lower its melting point. Think of it like freezing a soda- the ice forms as pure ice, while the rest of the soda gets more syrupy. The main difference is that unlike ice, solid iron sinks instead of floating.

Hope this helped!

Good luck my friend!

Brainliest is always appreciated :) <3

Is it possible to have kinetic energy and potential energy? What about neither? Give an example of each!
Serhud [2]
Yes they are both possible. An example of having both kinetic and gravitational potential energy could possibly be when you are travelling on a roller coaster. You are in motion and at a height. An example of neither could just be an individual sitting on a floor. They are neither in motion or at a height. Hope that helps :)
