Kepler-62e is an exoplanet that orbits within the habitable zone around its parent star. The planet has a mass that is 3.57 time
skad [1K]

Answer:

g' = 13.5 m/s²

Explanation:

The acceleration due to gravity on surface of earth is given by the formula:

g = GMe/Re²   --------------- euation 1

where,

g = acceleration due to gravity on surface of earth

G = Universal Gravitational Constant

Me = Mass of Earth

Re = Radius of Earth

Now, the the acceleration due to gravity on the surface of Kepler-62e is:

g' = GM'/R'²   --------------- euation 1

where,

g' = acceleration due to gravity on surface of Kepler-62e

G = Universal Gravitational Constant

M' = Mass of Kepler-62e = 3.57 Me

R' = Radius of Kepler-62e = 1.61 Re

Therefore,

g' = G(3.57 Me)/(1.61 Re)²

g' = 1.38 GMe/Re²

using equation 1:

g' = 1.38 g

where,

g = 9.8 m/s²

Therefore,

g' = 1.38(9.8 m/s²)

<u>g' = 13.5 m/s²</u>

The liquid pressure varies with depth why​
Solnce55 [7]

Explanation:

Hey, there!

The liquid pressure varies with depth because liquid pressure is directly proportional to the depth of liquid from the free surface of the liquid. so, more the depth more the pressure and less the depth less the pressure.

A square loop of wire, with sides of length a, lies in the first quadrant of the xy plane, with one corner at the origin. In thi
Ainat [17]

Answer:

emf=-\dfrac{1}{2}kta^5

Explanation:

Given that

B(y, t) = k y ³t²

To find the total flux over the loop we have to integrate over the loop

\phi =\int B.dS

Given that loop is square,so

\phi =\int B.dS

B(y, t) = k y ³t²

\phi =kt^2\int_{0}^{a}dx\int_{0}^{a}y^3dy

\phi =\dfrac{1}{4}kt^2a^5

We know that emf given as

emf=-\dfrac{d\phi }{dt}

\phi =\dfrac{1}{4}kt^2a^5

So

emf=-\dfrac{1}{2}kta^5
