Answer:

t = 1.02 s

Explanation:

The computation of the time required is shown below:

The package speed for belt is

= 3 -  1

= 2 m/s

Moreover, the decelerative force would be acted on the block i.e u.m.g

So, the decelerative produced

= 0.2 × 9.81

= 1.962 m/s^2

And, final velocity = 0

v = u - at

here

V = 0 = final velocity

 u = 2 m/s

so,

0 = 2 - 1.962 × t

t = 1.02 s

A physicist wants to measure the force required to push a heavy box up a ramp. What tools might the physicist use? What measurem
Flauer [41]

Answer:

Dynamometer

Explanation:

We might want to use a system that calculates weight, but we would need to change it for the task, depends entirely on the task. Let 's imagine we're taking a scale to test people's weight, and you're moving it between something that moves the box and the box that are being moved, because when we push you will see the scale calculate distance. Then force until the container continues to flow.

. Boxes are sitting on a conveyor belt as the conveyor is turned on, moving the boxes toward the right. The belt reaches full sp
oksian1 [2.3K]

Answer:

The acceleration of the boxes is 1.5 ft/s²

The displacement of the boxes during the speed-up period is 0.1875 ft.

Explanation:

Hi there!

Let´s convert the 45 ft/min into ft/s:

45 ft/min ·  1 min/ 60 s = 0.75 ft/s

It takes the belt 0.5 s to reach this speed. Then, the acceleration of the boxes will be:

a = v/t

Where:

a = acceleration.

v = velocity.

t = time.

a = 0.75 ft/s / 0.5 s

a = 1.5 ft/s²

The acceleration of the boxes is 1.5 ft/s²

The equation of displacement is the following:

x = x0 + v0 · t + 1/2 · a · t²

Where:

x = position of the boxes at time t.

x0 = initial position.

v0 = initial velocity.

t = time.

a = acceleration.

Since the origin of the frame of reference is located at the point where the boxes begin to move, x0 = 0. Since the boxes were initially at rest, v0 = 0. Then:

x = 1/2 · a · t²

x = 1/2 · 1.5 ft/s² · (0.5 s)²

x = 0. 1875 ft

The displacement of the boxes during the speed-up period is 0.1875 ft.

What additions must you make to the cell for it to generate a standard emf?
xeze [42]
Answer: Addition of salt bridge

To generate a standard electromotive force, an addition of salt bridge is essential to help maintain electrical neutrality within the internal circuit and prevent the cell from rapidly running its reaction to equilibrium.
In addition, salt bridge contains potassium sulfate, an inert electrolyte where its ions will diffuse into the separate half-cells to stabilize the building charges at the electrodes and produce electricity.
