Answer:

faster than u

Explanation:

Answer:

The first law of thermodynamics states that the change in the internal energy of a system equals the net heat transfer into the system minus the net work done by the system. This is another way of saying that energy can neither be created nor destroyed, but it can be converted from one form to another form.

A tea kettle that is warmed on an electric stove is receiving heat energy, this heat energy increases the kinetic energy of the water particles in the kettle and makes them to move faster. As time goes on, the water begins to turn into vapors. The heat energy that is released into the system is been used to carry out the work of evaporation and the whistling of the kettle.

How was the result of your physical fitness test in Flexibility and muscular

strength compared to your previous assessments?

Explanation:

Answer:

78 m

Explanation:

Initial v = 1 m/s

a = 4 m/s²

t = 6s

[tex]x = v_{i} t + \frac{1}{2}at^{2} \\x = (1)(6) + \frac{1}{2} (4)(6)^{2} \\x = 6 + 72\\x = 78[/tex]

Answer:

C. An article written by a scientist

Explanation:

Research-based original articles written by a scientist can act as a primary source of information. Textbooks, dictionaries and encyclopedias are generally classified as secondary sources and are rarely primary sources.

Answer:

Explanation:

I got everything but i. Don't know why but it's eluding me. So let's do everything but that.

a. PE = mgh so

   PE = (2.5)(98)(14) and

   PE = 340 J

b. [tex]KE=\frac{1}{2}mv^2[/tex] so

   [tex]KE=\frac{1}{2}(2.5)(14)^2[/tex] and

   KE = 250 J

c. TE = KE + PE so

   TE = 340 + 250 and

   TE = 590 J

d. PE at 8.7 m:

   PE = (2.5)(9.8)(8.7) and

   PE = 210 J

e. The KE at the same height:

   TE = KE + PE and

   590 = KE + 210 so

   KE = 380 J

f. The velocity at that height:

   [tex]380=\frac{1}{2}(2.5)v^2[/tex] and

   [tex]v=\sqrt{\frac{2(380)}{2.5} }[/tex] so

   v = 17 m/s

g. The velocity at a height of 11.6 m (these get a bit more involed as we move forward!). First we need to find the PE at that height and then use it in the TE equation to solve for KE, then use the value for KE in the KE equation to solve for velocity:

   590 = KE + PE and

   PE = (2.5)(9.8)(11.6) so

   PE = 280 then

   590 = KE + 280 so

   KE = 310 then

   [tex]310=\frac{1}{2}(2.5)v^2[/tex] and

   [tex]v=\sqrt{\frac{2(310)}{2.5} }[/tex] so

   v = 16 m/s

h. This one is a one-dimensional problem not using the TE. This one uses parabolic motion equations. We know that the initial velocity of this object was 0 since it started from the launcher. That allows us to find the time at which the object was at a velocity of 26 m/s. Let's do that first:

   [tex]v=v_0+at[/tex] and

   26 = 0 + 9.8t and

   26 = 9.8t so the time at 26 m/s is

   t = 2.7 seconds. Now we use that in the equation for displacement:

   Δx = [tex]v_0t+\frac{1}{2}at^2[/tex] and filling in the time the object was at 26 m/s:

   Δx = 0t + [tex]\frac{1}{2}(-9.8)2.7)^2[/tex] so

   Δx = 36 m

i. ??? In order to find the velocity at which the object hits the ground we would need to know the initial height so we could find the time it takes to hit the ground, and then from there, sub all that in to find final velocity. In my estimations, we have 2 unknowns and I can't seem to see my way around that connundrum.

Answer:

d, both

Explanation:

fission is the process of electrons from atoms coliding into other atoms which releases more electrons and when done right releases lots of energy.

fusion is the process of using intense heat and electromagnetic forces to force electrons to bind to atoms which releases lots of energy

Answer:

Monthly cost = 35.7

Explanation:

Given the following data;

Power = 7000 Watts

Time = 10 minutes

Number of days = 30 days

Conversion:

60 minutes = 1 hour

10 minutes = 10/60 = 0.17 hours

To find the monthly cost of electricity;

Energy = power * time

Energy consumption = 7000 * 0.17

Energy consumption = 1190 Watt-hour = 1.19 KWh (1 Kilowatts is equal to 1000 watts).

Next, to find cost of monthly energy consumption;

Cost = 1.19 * 30

Cost = 35.7

Answer:

Explanation:

1/1000

If a foot is 1/3 of a yard the 1/1000 part of a meter is a millimeter, therefore the correct answer is option D.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

Any additional quantity of that type can be stated as a multiple of the measurement unit.

As given in the problem a foot is 1/3 of a yard then we have to find out what part of a meter is a millimeter,

1 meter = 100 centimeters

1 centimeters = 10 millimeters

1 meter = 100×10 millimeters

1 meter = 1000 millimeters

1 millimeters = 1/1000 meter

Thus, the 1/1000 part of a meter is a millimeter, therefore the correct answer is option D.

often Positive and negative charges balance each other which gives an overall neutral charge. if they are unbalanced then it will result in static electricity.

Answer:

Explanation:

Average speed is found by adding together the total distances traveled by the athlete and divide that total by the total time it took.

Average velocity is vector, which means it includes direction. If the athlete heads one way and then turns around, his displacement might actually be negative! Yikes! Let's look at speed first:

[tex]s=\frac{600+1000}{2+1}=\frac{1600}{3}=533\frac{1}{3}\frac{m}{min}[/tex]

Velocity is the displacements added together divided by the total amount of time it took. The displacement is the same as the distance here, since the athlete did not veer off his straight-path and didn't turn around.

Average velocity = average speed = 533.3 m/min

Answer:

The answer is below

Explanation:

When a gallon is blown the air energy is saved as potential energy which is compressed inside the balloon. However, when the balloon is released without trying its neck, the air energy quickly turned to kinetic energy, in which the air energy keeps moving as the balloon float around the space.

Hence, in short, what happens in terms of energy when you blow up a balloon and release it without trying its neck​ is that the air energy moves from potential energy to kinetic energy.

Answer:

Atoms of elements with the same electons in the outer most shell they are put in the same group on the periodic table

Answer:

Explanation:

Time for one dot = 1 /50 = .02 s

Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s

velocity = 3 cm / .02 = 150 cm /s

Distance between 4 th and 5 th  dot is 4 cm and time taken to travel this distance is .02 s

velocity = 4 cm / .02 = 200 cm /s

change in velocity = 200 cm/s  - 150cm/s = 50 cm /s

Time taken = .02 s

Acceleration = 50 / .02 cm/s²

= 2500 cm/s²

Answer:

   I = 2.667 kg m²

Explanation:

The moment of inertia of a body can be calculated by the expression

         I = ∫ L² dm

For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is

         I = [tex]\frac{1}{12}[/tex] m L²

let's calculate

         I = [tex]\frac{1}{12}[/tex]  2  4²

         I = 2.667 kg m²
