Answer:

The Answer is B.)Convection is a more efficient method of heat transfer.

Explanation:

In fluids, such as water and air, convection is a much more efficient method of heat transfer than conduction.  Although conduction was at work in both cases, it transferred much less heat than convection.

C) No valid conclusion is suggested by these observations.

Explanation:

From the experiment, no valid conclusion can be drawn from the observations.

The tests are simply based on heat loss by a material.

  • In conduction, heat is lost by contact between materials in which heat flows from one to another.
  • Convection is a form of heat loss in which heat flows by density in fluids
  • The test carried out does not provide proof and comparison between heat loss by conduction and convection.

Light in air enter crown glass (n = 1.52) at an angle of 35 degrees. What is the refracted angle?
Dovator [93]

Answer:

22.17 degree

Explanation:

n = 1.52

Angle of incidence, i = 35 degree

Let the angle of refraction is r.

use the Snell's law

n = Sin i / Sin r

Sin r = Sin i / n = Sin 35 / 1 .52

Sin r = 0.37735

r = 22.17 degree

Thus, the ray is refracted at an angle of 22.17 degree.

Technician A says that daytime running lights (DRLs) light the headlights, usually at reduced intensity, whenever the engine is
miskamm [114]

Answer:

technician A is right

Explanation:

Daytime running lights are auxiliary lights that allow other cars to see us better. They are not intended to illuminate the road, so their intensity is low.

Consequently technician A is right

HID lights are high intensity lights, generally bluish-white in color, yellow lights are halogen lights with lower intensity than HID lights.

Consequently, technician B is wrong

maks197457 [2]

Answer:

34.8 and 55.2º

Explanation:

This is a projectile launching exercise, as we are told that the range of the arrow must be equal to its range and = 31 m let's use the equation

         

The scope equation is

         R = v₀² sin 2θ /g

         sin 2 θ = R g / v₀²

         sin 2 θ = 31 9.8 / 18²

         2 θ = sin⁻¹ 0.93765

          θ = 34.8º

At the launch of projectiles we have two complementary angles with the same range in this case 34.8 and (90-34.8) = 55.2º
