The force of air particles over an area is?
Answers
Answer;
Air pressure
Explanation;
- Pressure is the force that is applied over a unit of area. Air pressure is the weight of air molecules pressing down on the Earth. It is the force exerted by air particles on the earth's surface.
- The column of air extends to the top of the atmosphere. As one move up increasing the altitude, the air pressure decreases since the air column is reduced.

Answer:
The mass of the Al-duckie should be 30 kg.
Explanation:
We will use the first law of thermodynamics:
ΔU = m·Cv·ΔT
Since the specific heat of water is 4.185 J(gºC), the change in the water's internal energy would be:
ΔU = 100 kg · 4.185 J(gºC) · (42ºC - 38ºC) = 1674 KJ
Given that no heat is lost, all the internal energy that the water loses while cooling down will transfer to the duckie. So, if the duckie has ΔU = 1674 KJ and its final temperature is the desired 38 ºC, we can calculate its mass using the first law again:

Explanation:
-Hitting A Wall
-Rowing a boat
-Walking
Explanation:
1.If you hit a Wall with your hands or legs, you get hurt. Why?
Because of Newton's Third Law. You hit the wall with a force and that exact same amount of force is returned by the wall.
2. While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward.
3.While Walking, You push the floor or the surface you are walking on with your toes, And the surface pushes your legs up, helping you to lift your legs up.

Answer:
+16 J
Explanation:
We can solve the problem by using the 1st law of thermodynamics:
where
is the change of the internal energy of the system
Q is the heat (positive if supplied to the system, negative if dissipated by the system)
W is the work done (positive if done by the system, negative if done by the surroundings on the system)
In this case we have:
Q = -12 J is the heat dissipated by the system
W = -28 J is the work done ON the system
Substituting into the equation, we find the change in internal energy of the system:

E = Q /(4πε₀r²)
Note:
1 /(4πε₀) = k = 8.99 * 10⁹ Nm²/C²
Q = 6 μC = 6 * 10⁻⁶ C. r = 0.5m
E = kQ / r²
E = (8.99 * 10⁹ * 6 * 10⁻⁶) /(0.5²) Use a calculator
E = 215.6 * 10³ N/C
Electric field strength = 215 600 N/C.
I hope this helps.
