A sled slides down a hill, reaches the level surface, and eventually comes to a stop. Which fact ultimately explains why the sle

d stops?
A. The presence of an unbalanced force causes an object to move forward at constant velocity
B. The presence of an unbalanced force (e.g. friction) causes a moving object to stop
C. The presence of inertia causes a moving object to stop
D. The natural tendency of any object is to ultimately stop

Answer:

B. The presence of an unbalanced force(e.g friction) causes a moving object to stop.

Explanation:

As the friction is that force that can stop the sled upon reaching the levelled surface so the option b is correct.

What best describes the relationship between heat, internal energy, and thermal energy?
den301095 [7]
Internal energy is<span> the </span>energy<span> associated with the random, disordered motion of molecules. This energy </span><span>can not be transferred. whereas. </span>thermal energy<span> is the </span>energy<span> due to temperature </span>difference<span>. </span>

Thermal energy<span> is the </span>energy that comes due to temperature difference. It comes from heat  generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

The relationship between the heat, the internal energy and the thermal energy is the motion, whether of molecules (internal energy) or of particles (thermal energy).

A frying pan is quickly heated on a stovetop to 200 C. It has an iron handle that is 20 cm long . Estimate how much time should
myrzilka [38]

Explanation:

Heat = mc(change in temp.)

m=mass , c = specific heat

Rate of flow of heat = heat current = kA/L(T2-T1)

So, mass = density×volume

So, mc(T2-T1)/time =

kA/L(T2-T1)

Substitute the values given as there are a lot of values missing, so the answer can not be obtained.

Which two phrases describe a situation that will cause an object moving at a
notsponge [240]

Answer:

The phrases the describe the situation are A and C

Explanation:

1- If a car is at rest or uniform motion, it will remain in that condition until an external force acts on it. If the external forces acting on a body are balanced , it means that their sum is equals to 0, which eventually results that no Net force is acting on it.

For balance forces, ∑F = 0

2- If the car moving at a constant speed is slowing down, it means that the forces have become unbalanced, eventually resulting in a Net force in the opposite direction of the motion of the car, due to which it is slowing down

For unbalanced forces, ∑F ≠ 0

The question satisfies 2, which is the answer
