natali 33 [55]

Answer:

The work done is 120000 J.

Explanation:

Given that,

Weight = 600 N

Distance = 200 m

We need to calculate the work done

Using formula of work done

W=F\times d

Where, F = force

d = distance

Put the value into the formula

W=600\times200

W=120000\ J

Hence, The work done is 120000 J.

A conveyor belt is used to send burgers through a grill- ing machine. If the grilling machine is 1.2m long and the burgers requi
puteri [66]

Answer:

Rate = 1.71 burger/min

Explanation:

Length of the conveyor belt is given as

L = 1.2 m

time taken to cook one burger is given as

t = 2.8 min = 168 s

now we can find the speed of the belt as

v = \frac{distance}{speed}

v = \frac{1.2}{168}

v = 7.14 \times 10^{-3} m/s

Now we know that the distance between two burgers is given as 25 cm

d = 0.25 m/burger

now the production rate of burgers is given as

Rate = \frac{v}{d}

Rate = \frac{7.14 \times 10^{-3} m/s}{0.25 m/burger}

Rate = 0.0286\frac{burger}{sec}

Rate = 0.0286\times 60\frac{burger}{min}

Rate = 1.71 burger/min
