you did 150 J of work lifting a 120 N backpack. how much did the backpack weigh in pounds?(hint:there are 4.448 N in one pound)

1 answer:

3 0

If the backpack weighs 120 N, then the equivalent
weight in pounds is about 26.98 .

All that business about lifting and joules of work is
completely irrelevant to this question.

Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each o

harina [27]

Answer:

Distance covered by motorcyclist A = 700 - 300 = 400 km

Distance covered by motorcyclist B = 300 - 0 = 300 km

The time before they met went for 5 hours

Average speed of motorcyclist A would be: 400/5 = 80 km/hour

Average speed of motorcyclist B would be : 300/5 = 60 km/hour

Step-by-step explanation:

In the given question first we have to find the distance covered by each of them.

Look at the graph. Motorcyclist A started from 700 km and met at 300 km with motorcyclist B

Thus the distance covered by motorcyclist A = 700 - 300 = 400 km

Motorcyclist B started from 0 km and met with A at point 300 km.

Thus the distance covered by motorcyclist B = 300 - 0 = 300 km

Now we have to find the time before they meet.

Look at the graph. Both motorcyclists met at point t=5

Thus the time before they met went for 5 hours

Now find out the average speed of motorcyclists

To find the average speed we require total distance and time.

Motorcyclist A covered 400 km within 5 hours

Average speed of motorcyclist A would be: 400/5 = 80 km/hour

Average speed of motorcyclist B would be : 300/5 = 60 km/hour

Kiran has 10 1/2 feet of lumber and wants to make a bookshelfKiran needs two side panels that are each 5 2/3 feet. How much more

eimsori [14]

Total height of lumber, H = 10 1/2 feet = 21/2 feet .

Height of side panel, h = 5 2/3 feet = 17/3 feet .

Now,

Extra lumber required, L = 2 × Height of side panel - Total height of lumber

$L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet$

Therefore, extra lumber required is $\dfrac{5}{6}$ feet.

Hence, this is the required solution.
