Answer:
The angle of refraction for the ray moving through the liquid is = 32.3°
Explanation:
Refractive index of liquid (n₁/n₂) = sini/sinr
∴ n₁/n₂ = sini/sinr ................ equation 1
n₁ = index of refraction for glass, n₂ = index of refraction for liquid
Where i = incident angle of the first medium, r = angle of refraction or angle in the second medium.
Since the light ray is traveling from glass - to - liquid, the first medium is glass and the second medium is liquid. and the refractive index will be that liquid with respect to glass.
using the equation,
n₁/n₂ = sini/sinr
i = 35° , n₁ = 1.52, n₂= 1.63
Making sinr the subject of the equation above,
sinr = sini/(n₁/n₂)
sinr = sin35(1.52)/1.63
sinr =0.574(1.52)/1.63
sinr = 0.535
Taking the sin inverse of both side of the equation
sin⁻¹(sinr) = sin⁻¹(0.535)
∴ r = 32.3°
The angle of refraction for the ray moving through the liquid is = 32.3°
The right option is (b). 32.3°

Answer:
The universal law of gravitation.
PE = m * G M / R^2 potential energy of mass m due to attractive forces
If the kinetic energy of mass m is greater than the energy due to the attractive masses then then mass m can continue indefinitely away from the attracting masses.
Answer:
The solution(s) are in order with respect to the attachments
Joules ; 5. Adding the same amount of heat to two different objects will produce the same increase in temperature ; 2. Same speed in both ; 2. A
Explanation:
Diagram 1 ( Liquid Nitrogen ) : So as you can see, we want our units in Joules here, and can therefore multiply the mass of gaseous nitrogen and the latent heat of liquid nitrogen, to cancel the units kg, and receive our solution - in terms of Joules. Let's do it.
q ( energy removed ) = mass of nitrogen
latent heat of liquid nitrogen,
q = 1.3 kg
2.01
10⁵ J / kg =
=
=
=
Joules =
kiloJoules = 2.613
10⁵Joules is the energy that must be removed
Diagram 2 : The same amount of heat does not necessarily mean the same increase in temperature for two different objects. The increase in temperature depends on the specific heat capacity of the substance. Therefore your solution is 5 ) Adding the same amount of heat to two different objects will produce the same increase in temperature.
Diagram 3 : The temperatures in both glasses are the same, and hence the molecules have the same average speed. Therefore your solution is 2 ) Same speed in both.
Diagram 4 : Glass A has more water molecules, and hence has more thermal energy. Your solution is 2 ) A.
