A 1000-kg barge is being towed by means of two horizontal cables. One cable is pulling with a force of 80.0 N in a direction 30.0° west of north. In what direction should the second cable pull so that the barge will accelerate northward, if the force exerted by the cable is 120 N?

Answers

Answer 1
Answer:

Answer:

θ = 19.47°

Explanation:

given,

mass of the barge = 1000 kg

force applied to pull = 80 N

direction = 30° west to north

force exerted by the cable = 120 N

direction = ?

first cable is pulling

in north direction = 80 cos ∅

                             = 80 cos 30°

                             = 69.28 N

in west direction = 80 sin ∅

                             = 80 sin 30°

                             = 40 N

the other cable will pull in the opposite direction of west

now,

120 sin \theta = 40

sin \theta = (40)/(120)

\theta = sin^(-1){(1)/(3)}

θ = 19.47°

the direction of the cable will be equal to θ = 19.47°

Which of the following is an example of diffraction? A. Hearing a band play through an open doorway without seeing them. B. Sitting in a room and watching a band play. C. Playing in a band. D. None of these examples show diffraction.

Answers

A because diffraction is the bending of waves around small obstacles or openings. That’s why you can hear a band through an open doorway without seeing them

Geothermal energy cannot meet all of our energy needs because access to geothermal energy is _________.a. limited to certain regions.
b. the earth is not hot enough.
c. geothermal energy is intermittent.
d. geothermal sources do not have enough energy to generate electricity

Answers

Answer:

a. Limited to certain regions.

Explanation:

It will be wrong to say that the earth is not hot enough, geothermal energy is intermittent or this source is not enough to generate electricity. It is not the fuel, it's the earth which is continuously emitting radiation or heat and it will keep on emitting that. So it's the most consistent source of energy and is abundant enough to produce electricity. So the problem is, it's the location specific source of energy and can only be utilized at the places lying at the edges of the tectonic  plates. So the correct option is a.

B. Electrical energy

Among the choices given, the type of energy associated with electric currents is electrical energy. By its definition, electric current is the flow of charged particles through a conductor or a conduction medium, for example, a wire. Basically, it involves electricity. It is similar to water current but instead of water molecules, charged particles move down a conductor. These charged particles are mostly electrons which move freely and at random. When all the free electrons move in the same direction, a current is created.

When a woman stands with two feet on a scale, the scale reads 280 N. When she lifts one foot, the scale reads A. less than 280 N. B. more than 280 N. C. 280 N.

Answers

The right answer is  280 N.

What is total weight on the scale?

When a woman stands with two feet on a scale, the scale reads 280 N and when she lifts one foot, the scale also reads 280 N because the weight of the other leg also comes on the one leg.

First, the whole weight of the body depends on two feet but when the second feet is lifted, the weight of the whole body including the lifted feet comes on the single feed so we can conclude that the right answer is  280 N
