The net vertical force on a box F as a function of the vertical position y is shown below.

Answer:

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Explanation:

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):

[tex]T=\frac{1}{f}[/tex]

In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:

[tex]T=\frac{1}{5*10^{10} Hz }[/tex]

Solving:

T= 2*10⁻¹¹ seconds

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

The fequency is defined as the number of cycles achieved by the any wave it is expressed in hertz.

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):

[tex]T=\dfrac{1}{f}[/tex]

In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:

[tex]T=\dfrac{1}{5\times 10^{10}}=2\times 10^{-11}\ Sec[/tex]

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Thus a microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Answer:

The red car would experience the greatest acceleration.

Explanation:

Newton says that Force equals mass times acceleration or F = ma

We get a = F/m

If we want the greatest acceleration or a, mass or m must be the lowest.

Correct question:

Imagine that a 1200 kg vehicle speeds up from rest to 20.0 m/s in 80 s.

How much work was done on the car? (Answer in 3 sig figs)

Answer:

the work done on the vehicle is 2.40 x 10⁵ J

Explanation:

Given;

mass of the vehicle, m = 1200 kg

initial velocity of the vehicle, u = 0

final velocity of the vehicle, v = 20 m/s

time of motion of the vehicle, t = 80 s

The distance moved by the vehicle is calculated as;

[tex]s = (\frac{v + u}{2} )t\\\\s = (\frac{20+ 0}{2} )(80)\\\\s = 800 \ m[/tex]

The force applied to the vehicle is calculated as;

[tex]F = ma = \frac{m v}{t} = \frac{1200 \times 20}{80} = 300 \ N\\\\[/tex]

The work done on the vehicle is calculated as;

W = F x d

W = 300 x 800

W = 2.4 x 10⁵ J.

Therefore, the work done on the vehicle is 2.40 x 10⁵ J

Answer:

Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals have continuous electrical signals, while digital signals have non-continuous electrical signals.

Explanation:

Analog Signals   were used in many systems to produce signals to carry information.  These signals are continuous in both values and time. The use of analog signals has been declined with the arrival of digital signals. In short, to understand the analog signals –  all signals that are natural or come naturally are analog signals.  Digital Signals , unlike analog signals, digital signals are not continuous, but signals are discrete in value and time. These signals are represented by binary numbers and consist of different voltage values.  Their differences are as follows:

Analog Signals                                      Digital Signals

Continuous signals                               Discrete signals

Represented by sine waves               Represented by square waves

The Human voice, natural sound, analog electronic devices are few examples   Computers, optical drives, and other electronic devices

A Continuous range of values            Discontinuous values

Records sound waves as they are     Converts into a binary waveform.

Only be used in analog devices.        Suited for digital electronics like computers, mobiles, and more.

I think a Digital signal is better.

Answer:

nuclear fission

Answer:

156,800 N

Explanation:

Given: Width = 2.0 m Length = 4.0 m Depth =  2.00 cm. Density of water = 1000 Kg/m³

To find: What is the weight of the truck?

Formula: [tex]F = m[/tex] × [tex]9.8 m/s^2[/tex]

Solution: Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth. F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

Firstly, multiply the length, width, and depth.

[tex]2.0[/tex] × [tex]4.0[/tex] × [tex]2.00[/tex] [tex]= 16[/tex]

Next, the weight of the truck is found by multiplying the density of water, the result found by multiplying the length, width, and depth, and the formula;

[tex]1000 kg/m^3[/tex] × [tex]16[/tex] × [tex]9.8m/s^2[/tex][tex]= 156,800[/tex]

Therefore, the weight of the truck is 156,800 N

Q.1 - V = u + at

u = 0, a = g = 9.8, t = 1

V = 0+9.8*1 = 9.8 m/s

Q 2- In horizontal position the velocity remains same hence a= dv/t, since change in velocity is zero the acceleration also equal to zero

Q.3- After neglecting the air resistance at 45° angle the maximum range is obtained.

let's prove, consider the range have maximum angle at θ, now range is given by

R = u²Sin2θ/g where sin2θ can we written as 2sinθ.cosθ.

Now the range value is directly proportional to the product of sin & cos of firing angle & this maximum value is obtained at 45°

Q.4 The range of two angle will be same if and only if they give 90° on addition.

20+x = 90,

x = 90-20 = 70°

u=0m/s

v=?

a=9.8m/s²

t=1sec

now

we have

v=u+at

v=0+9.8*1

v=9.8m/s

angle is measured in sin and cos angle where maximum angle's value is gained by 45°

4.

we have

range

R=[tex]\frac{u²sin2\theta}{g}[/tex]

For

angle =20°

R1=[tex]\frac{u²sin2*20}{g}[/tex].......[1]

another angle be [tex]\theta[/tex]

R2=[tex]\frac{u²sin2\theta}{g}[/tex].......[2]

since R1=R2
