Answer:

Science experiment: Inclined plane

(Your name)

8th grade AP Science

(Teachers name)

(todays date or due date)

Hypothesis:

If the height of the inclined plane increases, then the IMA, AMA will increase And efficiency will decrease. This will be because a sharper incline will require more energy over a shorter distance than a shallow incline.

Trial: 1

Height: 11.15 Cm

Length: 56.60 Cm

Mass: 500 g (4.90 N)

Effort Force: 1.35 N

AMA: 3.63

IMA: 5.08

Efficiency: 71.46

Trial: 2

Height: 17.40 Cm

Length: 56.60 Cm

Mass: 500 g (4.90 N)

Effort force: 1.75 N

AMA: 2.80

IMA: 3.25

Efficiency: 86.15

Questions for “presenting your outcome”:

How does the length to height ratio (the IMA) of trial 1 compare to trial 2?

Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?

If a machine was 100% efficient, how would the AMA compare to the IMA?

Answers to those questions:

1: The IMA in trial 1 is greater than in trial 2 because an inclined plane with a shallower rise will have a higher ideal mechanical advantage because less effort can be applied over a greater distance in a shallow rise than in a steep one.

2: IMA of an inclined plane does not account for things like gravity weighing an object down and friction being generated between the object and the plane, among other factors. Because both of the listed factors are things that we know will affect the object being moved up the inclined plane, we can predict that the AMA will be lower because outside factors acting on the object make the inclined plane less efficient.

3: If a machine was 100% efficient, the IMA and AMA would be congruent. This is because for a medicine to be 100% efficient there would have to be no outside forces acting on the object. The ideal mechanical advantage does not calculate for outside forces, so with a machine having to be a place where exactly 0 outsides forces are present to be working at 100% efficiency, then common logic would say that the IMA and AMA would have to be the exact same.

Questions for the “answer portion of the assignment”:

According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)

Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.

Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.

Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.

A 15.4 kg block is dragged over a rough, horizontal surface by a constant force of 182 N acting at an angle of 24◦ above the hor

Dima020 [189]

Answer:

Explanation:

Considering Work done by friction is asked

Given

mass of block $m=15.4\ kg$

force $F=182\ N$

inclination $\theta =24^{\circ}$

block is displaced by $s=57.6\ m$

coefficient of kinetic friction $\mu _k=0.135$

Friction force $F_r=\mu _kN$

Normal reaction $N=mg-F\sin \theta =15.4\times 9.8-182\sin (24)$

$N=76.9\ N$

Friction Force $F_r=0.135\times 76.9=10.38\ N$

Work done by friction force

$W=f_r\cdot s$

$W=10.38\times 57.6=597.92\ N$

An air-filled parallel-plate capacitor is constructed with a plate area of 0.40 m2 and a plate separation of 0.10 mm. It is then

seropon [69]

Answer:

The charge stored is $Q = 4.25 *10^{-7 } \ C$

The energy stored is $E = 2.55*10^{-6} \ J$

Explanation:

From the question we are told that

The area of the plates is $A = 0.40 \ m^2$

The separation between the plate is $d = 0.10 \ mm =0.0001 \ m$

The potential difference is $V = 12 \ V$

The permitivity of free space is $\epsilon_o = 8.85 *10^{-12} C^2 \cdot N^{-1} \cdot m^2$

The dielectric constant of glass is K = 5.0

Generally the capacitance of this capacitor is

$C = \frac{\epsilon_o * A}{d}$

substituting values

$C = \frac{8.85*10^{-12} * 0.40}{0.0001}$

$C = 3.34 *10^{-8} \ C$

The charge stored is mathematically evaluated as

$Q = CV$

substituting values

$Q = (3.54*10^{-8} * 12)$

$Q = 4.25 *10^{-7 } \ C$

The energy stored is

$E = 0.5 * CV^2$

substituting values

$E = 0.5 * (4.25 *10^{-7} * 12^2)$

$E = 2.55*10^{-6} \ J$

Please help me with this question. BRAINLIEST if answered.

IceJOKER [234]

... The top branch of the 3-branched parallel block ... the 9 and 6 in series ...
is equivalent to a single resistor of 15 ohms.

... The 3-branched parallel block boils down to (30, 10, and 15) in parallel.
That's (1/30 + 1/10 + 1/15)⁻¹ = 5 ohms.

... The 5-ohm-equivalent block and the 20-ohm resistor form a
voltage divider across the battery.
The voltage across the 5-ohm-equivalent block is (5/25 x 30v) = 6v .

... The top branch of the block is equivalent to a (9 + 6) = 15-ohmer.
With 6v across its ends, the current through that branch is (6/15) = 0.4A .

... With 0.4A flowing through it, the 9-ohm resistor is dissipating

I²R = (0.4A)² (9 ohms) = (0.16 A²) (9 ohms) = 1.44 W (choice-3)
