What is the weight of a glider with a mass of 4.9 grams?

timama [110]

Answer:

0.0481 N

Explanation:

The mass of a body is the quantity of matter stored in that body. It is a property that measures resistance to acceleration when a force is applied. The S.I unit of mass is the kilogram (kg).

The weight of a body is the force exerted on that body by gravity. The S.I unit of weight is the Newton (N). The weight of an object can also be defined as the force acting on the object. The formula for weight is:

Weight (W) = Mass (m) × acceleration due to gravity(g).

Giving that: mass (m) = 4.9 g = 0.0049 g and acceleration due to gravity (g) = 9.81 m/s².

Therefore, Weight (W) = 0.0049 × 9.81 = 0.0481 N

What is the non-linearity error, as a percentage of full range, produced when a 1K Ω potentiometer has a load of 10KΩ & is a

Darina [25.2K]

Answer:

2.28%

Explanation:

Being at one third of its maximum range a potentiometer should output V0/3.

However if this 1kΩ potentiometer has a 10kΩ load:

(1) I1 = I2 + I3

(2) V0 = I1 * 2/3*Rp + I3 * 1/*Rp

(3) Vp = I2 * Rl

(4) Vp = I3 * 1/3 * Rp

Where

I1: current entering the potentiometer

I2: current going to the load

I3: current going to the other leg of the potentiometer

V0: supply voltage

Vp: output voltage of the potentiometer

Rp: total resistance of the potentiometer

Rl: load resistance

First we determine the intensity of I3 in function of supply power

I3 = 3 * Vp / Rp = 3 * Vp / 1000 = 0.003*Vp

Then the load current

I2 = Vp / Rl = Vp / 10000 = 0.0001*Vp

With these we determine I1

I1 = 0.003*Vp + 0.0001*Vp = 0.0031*Vp

Then

V0 = 0.0031 * Vp * 2/3*Rp + 0.003*Vp * 1/3*Rp

V0 = 0.00207 * Vp * Rp + 0.001 * Vp * Rp

V0 = 0.00307 * Vp * 1000

V0 = 3.07 * Vp

Vp = V0 / 3.07

Vp = 0.3257 * V0

Now the percentage error is:

(100 * (0.3333 - 0.3257)) / 0.3333 = 2.28 %
