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.

What three forces contribute to the rise of water in a capillary tube?
Leviafan [203]
These three forces are cohesive force, adhesive force and surface tension. The cohesive and adhesive forces are opposite of each other. While cohesive force is the intermolecular bonding between like molecules, the adhesive force is the intermolecular force between unlike molecules. Surface tension is perceived to be the force exerted by the liquid near the surface of the water. Together, these forces bring about an increase in liquid height when a very small tube is placed on a wide surface liquid.

What is the wavelength of a radiowave that has a frequency of 9.650 x10^7 Hz (cycles per second)?h = 6.6261 x10^-34 J/sc = 2.998
slava [35]

Hello!!

For this, we only need frequency and speed, so for calculate we applicate formula:

\boxed{\lambda = V/f}

\textbf{Being:}

\sqrt{} \lambda = Wavelength = \   ?

\sqrt{} V = Velocity = 2.998*10^{8} \ m/s

\sqrt{} f = Frequency = 9,650*10^{7} \ Hz

\text{Then let's \textbf{replace it according} we information:}

\lambda = 2,998*10^{8} \ m /s  / 9,650*10^{7} \ Hz

\lambda  =  3.106 \ m

\textbf{Result:}\\\text{The wavelength of the radiowave is \textbf{3.106 meters}}

Why can the internal resistance of the DMM can be determined without taking into account the 100 Ω resistor? Could this be done
tester [92]

Answer:

Explanation:

For resistances in parallel we know that the overall resistance will be smaller in the value than any individual resistance. so, in this case we are concerned about \frac{1}{R} = \frac{1}{Rs} ⁺ \frac{1}{Rp}

where Rs is the series resistor and Rp is the parallel resistor.

so, R = 0.9M, roughly.

So, as the infernal resistance is very high as compared to the resistance conntected in parallel that is 100 Ω is not be used.
