What would be the net force and in what direction for the motion to be? The first one* and explain
Marta_Voda [28]

Answer:

11. 5 N to the left.

12. 10 N to the right.

Explanation:

11. Determination of the net force.

Force in the left direction (Fₗ) = 10 N

Force in the right direction (Fᵣ) = 5 N

Net force (Fₙ) =?

The net force can be obtained as follow:

Fₙ = Fₗ – Fᵣ (Since the forces act in opposite direction)

Fₙ = 10 – 5

Fₙ = 5 N to left

Thus, the net force is 5 N to the left.

12. Determination of the net force.

Force in the right direction 1 (Fᵣ₁) = 5 N

Force in the right direction 2 (Fᵣ₂) = 5 N

Net force (Fₙ) =?

The net force can be obtained as follow:

Fₙ = Fᵣ₁ + Fᵣ₂ (Since the forces act in the same direction)

Fₙ = 5 + 5

Fₙ = 10 N to the right

Thus, the net force is 10 N to the right.

When a piece of aluminium foil is taken out of the oven and cools from 1000C to 500C. What is the change in temperature?
zmey [24]

Answer:

Conduction

Explanation:

When one object touches another heat moves through it (think of a saucepan on a hot stove). Aluminium foil is a great conductor of heat, which means it is a poor insulator when it is in direct contact with something hot.

As temperature of this substance rises from 20°C to 50°C, the substance _______ heat and its kinetic energy _________ .
stellarik [79]

Answer:

absorbs heat and its kinetic energy increases.

Explanation:

As we know that heat is defined as the change in the temperature as there is increase in the temperature change then the heat will increase or decrease with respect to increase or decrease in temperature change.

In the given, question temperature is changing from 20° to 50° which means there is increase in the temperature which results in the absorption of heat. And increase temperature will increase the average speed of the molecules which results in increase in kinetic energy.
