This can be answered using the beat frequency formula, which is simply the difference between 2 frequencies.

Let: <span>fᵇ = beat frequency
</span>f₁ = first frequency
f₂ = second frequency

fᵇ = |f₁ - f₂|

substituting the values:
fᵇ = |24Hz - 20Hz|
fᵇ = 4Hz

The unit Hz also means beats per second, therefore:
<span>fᵇ = 4 beats per second
</span>
Therefore, the answer is C. 4

When testing a laptop power connector, how close should the voltage measured be to the accepted voltage of the laptop?
elixir [45]
When testing a laptop power connector, the voltage measured has be close to +/- 5% to the accepted voltage of the laptop. This is to ensure that the power connector would not pose any hazard to the user and is safe for use. So, for instance the accepted voltage is 19 V, when you test the power connector it should be that the reading is between 18 V to 20 V. Any reading below or above that range is not recommended for use. You can locate the accepted voltage on the battery or the laptop itself. To test a power connector, you can use a volt meter or a multi meter.

The moon Phobos orbits Mars
Soloha48 [4]

Answer:

Explanation:

We are basically needing to solve for the time in the equation d = rt, where d is the distance around Mars (aka the circumference), r is the velocity, and t is time. We need to find the circumference and the velocity. We will begin with the velocity.

Because the gravitational attraction between Phobos and Mars provides the centripetal acceleration necessary to keep Phobos in its (sort of) circular path, the equation we use for this is:

F_g=F_c which says that Force supplied by gravity is equal to the centripetal force. Expanding that:

\frac{Gm_{Phobos}m_{Mars}}{r^2}=\frac{m_{Phobos}v^2}{r}

When we move that around mathematically to solve for the velocity value, what we end up with is:

v=\sqrt{\frac{Gm_{Mars}}{r} and filling in:

v=\sqrt{\frac{(6.67*10^{-11})(6.42*10^{23})}{9.38*10^6} } and we get that

v = 2100 m/s

Now for the circumference:

C = 2πr and

C = 2(3.1415)(9.38 × 10⁶) so

C = 5.9 × 10⁷

Putting that all together in the C = vT equation:

5.9 × 10⁷ = 2100T so

T = 2.8 × 10⁴ sec or 7.8 hours

Starting from rest, a runner at a track meet reaches a speed of 7.5 m/s in 1.7 s. How far does she run during this time, assumin
Alex17521 [72]
For this problem, we use the equations derived for rectilinear motion at constant acceleration. The equations are:

a = (v - v₀)/t
x = v₀t + 0.5at²
where
a is acceleration
v and v₀ are the final and initial velocities, respectively
x is the distance
t is the time

First, let's determine the a to be used in the second equation:

a = (7.5 m/s - 0 m/s)/1.7 s = 4.411 m/s²
x = (0)(1.7s) + 0.5(4.411 m/s²)(1.7 s)²
x = 6.375 m

What is the mass of a skier if they are applying a force of 500N and they are accelerating at 20m/s2?
Brrunno [24]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

We know that,

  • force = mass \times acceleration

  • 500 = m \times 20

  • m =  \dfrac{500}{20}

  • m = 25

Mass of skier is <u>25</u> kg
