DENIUS [597]2 years ago

Answer:

1.5 m

Explanation:

Let the distance from the box to the pivot be c.

Let the distance from the pivot to the effort be y.

From the question given above, the following data were obtained:

Effort force (Fₑ) = 7 N

Force of resistance (Fᵣ) = 14 N

Distance from the box to the pivot (c) = 0.75 m

Distance from the pivot to the effort (y) =?

Clockwise moment = Fₑ × y

Anticlock wise moment = Fᵣ × c

Clockwise moment = Anticlock wise moment

Fₑ × y = Fᵣ × c

7 × y = 14 × 0.75

7 × y = 10.5

Divide both side by 7

y = 10.5 / 7

y = 1.5 m

Therefore, the distance from the pivot to the effort is 1.5 m

A positive test charge q is released from rest at distance r away from a charge of +Q and a distance 2r away from a charge of +2
Svetradugi [14.3K]

Answer:

B. to the right

Explanation:

Given:

  • test charge +q
  • distance of the test charge from +Q, r
  • distance of test charge from +2Q, 2r

<u>Force on the test charge due to +Q:</u>

F_1=k.\frac{Q.q}{r^2}

<u>Force on the test charge due to +Q:</u>

F_2=k.\frac{2Q.q}{(2r)^2}

F_2=k.\frac{Q.q}{2r^2}

Since all the charges are positive here, so they will try to repel the test charge away. And the force due to charge +Q will be greater so initially the test charge will move rightwards away from the +Q charge.

g The input piston of a hydraulic has a radius of 4.8 cm and moves 19.9 cm during a single stroke. If the output force is 6 time
ozzi

To solve this problem we will apply Pascal's principle for which we know that the pressure relation between two surfaces under the same fluid is given by the relation between the applied force and the area which receives-prints the force. Mathematically this is,

P_1 = P_2

\frac{F_1}{A_1}=\frac{F_2}{A_2}

\frac{F_1}{\pi r_1^2}=\frac{F_2}{\pi r_2^2}

For the relation given we have,

r_1 = 4.8cm

F_2 = 6F_1

Replacing,

\frac{F_1}{\pi 4.8^2}=\frac{6F_1}{\pi r_2^2}

r_2 = \sqrt{(6)(4.8^2)}

r_2 = 11.75cm

Finally we have that the work done on both sides should be equal then

F_1d_1 = F_2d_2

F_1d_1 = 11F_1d_2

d_2 = \frac{x_1}{11}

x_2 = \frac{19.9}{6}

x_2 = 3.31cm

two objects were lifted by machine one object had a massive 2 kg it was lifted at a speed of 2 m/s the other had a massive 4 kg
rosijanka [135]
Kinetic energy =(1/2) (mass) (speed²)

First object:  KE = (1/2) (2 kg) (2m/s)² =  4 joules during the lift.

Second object:  KE = (1/2) (4kg) (3 m/s)² = 18 joules during the lift.

The second object has more kinetic energy while it's being lifted
than the first object has while it's being lifted. Once they reach their
final heights and stop, neither object has any kinetic energy.
