A

Explanation:

Likurg_2 [28]3 years ago
6 0

The correct answer is 24,000,000,000 km.

One AU(Astronomical Unit) is equal to 1.496 ×10⁸ kilometers.

∴ 160 AU = 160 × 1.496 ×10⁸ km

= 240 ×10⁸ Km = 24,000,000,000 km

Gina applied 1,780 J of work to move a sofa 3.8 meters. What amount of force did she exert?
Gnoma [55]

Answer:

468.42N

Explanation:

Here,

Work done(W)=1780J

Displacement(s)=3.8m

As we have,

Work=Force×displacement

Now,

\hookrightarrow 1780J=F\times3.8m\\\\\hookrightarrow \frac{1780J}{3.8m} =F\\\\\hookrightarrow F=468.42N

there are two types of waves: electromagnetic and mechanical. can either type travel regardless of the presence of a medium?
Dmitry_Shevchenko [17]

Yes, electromagnetic can travel without medium.

Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us.

Waves in water and sound waves in air are two examples of mechanical waves.

Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma.

Matter that waves are traveling through is called a medium.

These mechanical waves travel through a medium by causing the molecules to bump into each other, like falling dominoes transferring energy from one to the next.

Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves.

On the other hand electromagnetic waves don't require medium for its propagation.

An easy example would be light which is an EM wave reaches earth even though space has no medium.

You apply a 150 N push on a frictionless sled over a period of 2 seconds. Show that the sled’s momentum changes by 300 kg·m/s.
Savatey [412]

Explanation:

Given parameters:

Force applied = 150N

Time  = 2s

Unknown:

Momentum change = ?

Solution:

The momentum change of a body is the difference between its initial and final momentum.

Momentum is the same as the impulse exerted on a body which is the product of force  and time

   Momentum = mass x velocity = force x time

The body initially at rest has a momentum of 0, as the momentum changes;

      Momentum change = Final momentum - initial momentum

                                         = f x t - (0)

                                         = (150 x 2) - 0

     Momentum change = 300kgm/s

Since the body is a frictionless surface, the net force is the same as the applied force.

Suppose you display a 1 kHz, 2 V sine wave in channel A and a DC, 1V signal in channel B with sensitivities set on 1V/div. You s
defon

Answer:

You are going to see the AC functions shifted down

Explanation:

Because you had a positive DC signal first, you had to readjust the position to the middle, otherwise, the sum of AC and DC would have been shifted up; because of this, your cursor has been moved down and ones the DC disappears from channel B the signal will be shifted down.

Note: Changing from DC to AC in channel B will kill all the DC signal
