Answer:

A. Heat flows from an object at higher temperature to an object at lower temperature

Explanation:

The option A obeys the 2nd law of thermodynamics. The heat will flow from the object at higher temperature to the object at Lower temperature till they reach an equilibrial state.

Heat doesn’t necessarily flow from an object with higher thermal energy to an object with lower thermal energy because an object has a higher thermal energy when it’s mass is more than the other. This makes B wrong.

C is wrong because heat moves from an object with higher temperature to objects with Lower temperature regardless of the state of matter.

On earth, the solar constant is approximately I = 1367 W/m2 . This corresponds to the power per unit area that a detector at the
d1i1m1o1n [39]

Answer:

Explanation:

for earth -sun system

E = σ T⁴ ,  E is radiation emitted by sun at temperature T

E = 4π R₁²  x solar constant on earth , R₁ is distance between earth and sun.

for marsh -sun system

E = σ T⁴ ,  E is radiation emitted by sun at temperature T

E = 4π R₂²  x solar constant on Mars , R₂ is distance between earth and sun.

from two equation ,

4π R₂²  x solar constant on Mars = 4π R₁²  x solar constant on earth

solar constant on Mars = (R₁ / R₂ )² x solar constant on earth

Alexeev081 [22]

If you float a piece of wood in a container half-full of water that rests on a weighing scale, the weight reading on the scale will increase.

<h3>What is Buoyancy?</h3>

Buoyancy is the force through your fluids or total or submerged bodies. Also known as Archimedes' theorem. The fluid of the direction on the body produces a resultant force but with the direction of the weight, with the opposite direction, upwards.

All material submerged in a liquid under the action of buoyancy, for this reason we have that the value on the scale will be increased with a system of a wood floating in water.

A soldier throws a grenade horizontally from the top of a cliff. Which of the following curves best describes the path taken by
Natasha_Volkova [10]

Answer:

4. Parabola

Explanation:

The motion of the flight of the grenade is a projectile motion, it's shape is best illustrated using a parabolic diagram.

It's not a circle as the path is not totally round.

It's not an ellipse as the path of motion is not a a completely bounded shape.

Its not a hyperbola as a hyperbola is an open curve with two branches.

Its a parabolic shape because a parabola has just one branch
