Answer:

D. Distance

Explanation:

Power is work divided by time. Work is force times distance, therefore you need distance in order to find power.

Answer:

Explanation:

a ) The centre of mass of a can filled completely with any liquid of any mass lies at the center of the can or at height h /2 where h is height of the can . So centre of mass of can of mass .140 kg of height 12 cm will lie at height 6 cm . Similarly center of mass of its content will also lie at height 6 cm that is center  point of the content .

Hence overall center of mass of can along with its content will lie at height 6 cm initially  .

b )

After the can loses all the soda , can becomes empty . Hence its center of mass will lie at its center again  .

c ) Its center of mass remains unchanged as the soda drains out completely .

d ) When soda starts draining out of the can , its lower part becomes heavier than the upper part . Hence its center of mass moves downwards . Its height is lowered . As height of soda is lowered in the can , center of mass also is lowered . It reaches its lowest point when soda in the can reaches half the height or when the can is half filled .

After that center of mass again starts rising upwards until the can is completely empty .

Answer:

1. evidence log

2. chain of custody

Explanation:

plato

Evidence log and chain of custody are two documents must he attach to every item of evidence.

A chain of custody log is used to demonstrate that the integrity of the evidence was upheld from the time it was seized until it was produced in court. Chain of custody logs provides information on the collection, examination, and preservation of data for production.

Evidence logs keep track of the operations carried out when Event Data was being created. Together with the Evidence Records, they should be read. Evidence logs are compiled every day and consist of a series of entries, each of which describes a specific action.

Therefore, he should attach an evidence log and chain of custody to every item of evidence.

Answer:

201.06m/s

Explanation:

The solve this problem, we must understand that momentum must be conserved.

This implies that the starting momentum must be the same as the ending momentum. Since we are dealing with an inelastic collision:

      Momentum of Plane  + Momentum of truck  = Momentum of plane + truck

    Mp x Vp  +  Mt x Vt  = V(Mp + Mt)

M is the mass                            

V is the velocity

t is truck

p is the plane

     (540000 x 210) + (24000 x 0)  = V (540000+24000)

            113400000 = 564000V

                  V  = 201.06m/s

Answer:

3.33m/s

Explanation:

Given parameters:

M1  = 1000kg

V 1 = 10m/s

M2  = 2000kg

V2  = 0m/s

Unknown:

Final velocity of the two combined vehicles = ?

Solution:

This is a typical example of an inelastic collision.

 Here, it is pertinent that momentum must be conserved;

So;

       M1 V1 + M2 V2  = V (M1 + M2)

      1000 x 10  +  2000 x 0  = V (1000 + 2000)

                 10000 = 3000V

                     V  = 3.33m/s

Answer:

g = 3.125 m/s²

Explanation:

To find the acceleration due to gravity we will use the second equation of motion:

[tex]h = V_{i}t + \frac{1}{2}gt^{2}\\[/tex]

where,

h = height = 1 m

Vi = initial speed object = 0 m/s (object is initially at rest)

t = time taken = 0.8 s

g = acceleration due to gravity = ?

Therefore,

[tex]1\ m = (0\ m/s)(0.8\ s)+\frac{1}{2}g(0.8\ s)^{2}\\\\\frac{2\ m}{0.64\ s^{2}} = g\\\\[/tex]

g = 3.125 m/s²

Answer:

72m

Explanation:

Given parameters:

Speed of the Burrito  = 4m/s

Time  = 18s

Unknown:

Distance covered by the flying Burrito = ?

Solution:

Speed is the rate of distance covered per unit of time.

        Speed  = [tex]\frac{distance}{time}[/tex]  

 Distance  = Speed x time

So;

 Distance  = 18 x 4  = 72m

Answer:

the net charge in the shell is 3.7699 × 10⁻⁸ C or 3.7699 × 10⁻² μC

Explanation:

Given that;

Inner radius r = 4.0 cm = 0.04 m

Outer radius R = 6.0 cm = 0.06 m

b = 3.0μC/m² = 3.0 × 10⁻⁶ C/m²

we know that volume density = b/r

Now consider spherical shell inside the given shell with radius r and with of dr

the volume of the spherical shell will be;

dv = 4πr².dr

Now total change in this shell will be;

dQ = P.dv

so

dQ = b/r . 4πr².dr

dQ = b × 4πr.dr

Q = 4πb  [tex]\int\limits^R_r {r} \,dx[/tex]

Q =  4πb[ r²/2 ][tex]^R_r[/tex]

Q =  4πb[ R²/2 - r²/2 ]

Q =  2πb[ R² - r² ]

so we substitute our values

Q =  2π×3.0 × 10⁻⁶[ 0.06² - 0.04² ]

Q =  2π×3.0 × 10⁻⁶ × 0.002

Q = 3.7699 × 10⁻⁸ C or 3.7699 × 10⁻² μC

Therefore, the net charge in the shell is 3.7699 × 10⁻⁸ C or 3.7699 × 10⁻² μC

I forgot the answer but I read it early

Answer:

1.4m/s

Explanation:

Average velocity is the total distance covered divided by the total time taken.

 Average velocity  = [tex]\frac{total distance }{time }[/tex]  

 Total time taken  = 5s + 6s  = 11s

The first distance covered  = velocity x time  = 1.4 x 5 = 7m

     second distance covered  = velocity x time  = 1.4 x 6  = 8.4m

So;

  Average velocity  = [tex]\frac{7 + 8.4}{11}[/tex]    = 1.4m/s

Explanation:

The computation of the force exerted by the seat on the pilot is as follows:

[tex]F = Mg + \frac{MV^2}{R}\\\\= 70 \times 9.81 + \frac{70 \times 120^2}{100}\\\\= 10766.7 N[/tex]

Hence, the  force exerted by the seat on the pilot is 10766.7 N

Answer:

When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. The escaping air exerts a force on the balloon itself. ... That opposing force—called thrust, in this case—propels the rocket forward.

Answer:

x = 21.7 cm

Explanation:

The energy stored in the spring is given by :

[tex]U=\dfrac{1}{2}kx^2[/tex]

Where

k is spring constant

x is compression or elongation in the spring

Let us assume that the spring constant of the spring is 6740 N/m.

We can find x by using above formula.

[tex]x=\sqrt{\dfrac{2U}{k}} \\\\x=\sqrt{\dfrac{2\times 160}{6740}} \\\\x=0.217\ m[/tex]

or

x = 21.7 cm

Hence, to store 160 J of energy, it must compress 21.7 cm.

b) inside

c) minor

therefore the phrase would be:

(a) The net charge is always zero ---INTERIOR--- the surface of an isolated conductor.

(b) The electric field is always zero ---INSIDE--- a perfect conductor.

(c) The charge density on the surface of an isolated, charged conductor is highest where the surface is ---MINOR---to)

How Can You Earn Your GED?

>Rules

You must be at least 16 years old to take the GED Test, and you must not be enrolled in high school. You should also meet state eligibility requirements for the amount of time you've been out of high school. In some states, you have to be out of high school for at least 60 consecutive days before you're allowed to take the test. Contact the program administrator in your state for more details.

You must pass all four subject tests in the GED battery of tests, which means scoring at least a 145 on each test (New Jersey requires a score of at least 150 to pass). Scores range from 100 to 200 on the 2014 version). A score of 165 on each test is the benchmark for college and career readiness, and you will receive an Honors distinction if you reach this score. The four tests take seven and a half hours total and are administered by computer. You don't have to take them all on the same day, but some states enforce specific time frames for completing the tests. Most questions are multiple choice, although there is also a mix of fill-in-the-blank, drag and drop, and select-an-area questions, as well as an essay question on the Reasoning Through Language Arts section.

If you don't pass a test the first time around, you can retake it, although different states have different requirements for people who need to retake GED tests (such as additional fees or proof of attending a preparation class). Testing accommodations are available for those with disabilities; you can sign up for them through your online account after you register. You usually have to pay to sign up for the tests, but the cost varies from state to state. After you take each test, you will receive your scores within 24 hours. Here are some more details about the score report.
