A car of mass 500 kg is moving at a speed of 1.2 m/s. A man pushes the car, increasing the speed to 2 m/s. How much work did the man do?
A. 1360 J
B. 360 J
C. 640 J
D. 1000 J​

Answers

Answer:

Option B - 360 J

Explanation:

One of the formulas used to find out how much work was done is :

E = 0.5×m×v² (where m is the mass and v is the velocity)

Now we substitute values from the question and simplify :

E = 0.5×500×1.2²

E = 250×1.2²

E = 250×1.44

E = 360 J

So our answer is Option B

The power in a circuit is 2 W and the voltage is 20 VDC. What's the circuit current?

Answers

Answer:

Power in the circuit is 0.1 amp

Explanation:

The power in the circuit is given by the formula

      P = V x I

Where P is Power, V is voltage supplied and I is current in circuit.

so,      I = P/v

            = 2/20

            =0.1 A

Select the correct texts in the passage.Which two lines best reflect how the setting influences Inges daily life?The wall was just a few feet from the home Inge shared with her parents. Aside from her school and other crumbling buildings in their neighborhood, their world was a few rooms in a dull, gray concrete flat with no yard and no trees. The wall was part of the view from the only windows they had, and Inge was drawn to the sounds she often heard from the other sidelaughter, shouting, music, and the noise of busy traffic.One day, as she explored the wall imagining what the sounds meant, she came upon a hole. Her heart thumped wildly as she leaned toward it. Through the hole, Inge caught a glimpse of a whole new world. It was a world of colorreds, blues, and yellows in the dresses of women strolling down the street, the colors of the shirts and ties the men wore, the colors of the ribbons in the little girls' braids. It was a world of people who did not begin and end each day in shades of gray. It was alive and brimming with activity, with living. Inge leaned, transfixed by the view, for hours until she began to feel the strain in her back and leg muscles. Then, pulling herself away, she headed home, knowing she would return again and again.One fall day in 1990, as Inge headed for her favorite spot in the wall, she noticed that the towers from which the guards viewed her neighborhood were empty. And she noticed something else: she was not alone. Others, mostly young men with a mix of other people, some of whom she recognized were at already at the wall or moving toward it.
