Answer:
0 as 1/7 = 0.142857143
1/7 = 5/35
We can get this number by 1/7 x 1000 = 1000 / 7
= 142.857143
Then move 3 decimal place.
So what is 27+22? Is it
A 8338
B 8282
C 8228
D 8234
Answer:
You put the add sign, so it would be 49. I don't believe that is what you meant to put though.
Explanation:
i gotchu, 27+22 so you take the 8 and multiply that by the number of times you blink every 2 minutes and then divide that by 0×1 and carry the 3 and that gives you -7
4. Compare how thermal and electrical energy transfer between objects and give an example of how you can
experience electrical energy and thermal energy in daily life.
5. Explain the statement "No one really makes energy" and "No one really uses up energy" by using the Law of
conservation of energy and an evidence of energy transformations given in the text.
Answer:
4) we take a can of cold soda there is a transfer from hand to can. a current passes through a light bulb, it becomes incandescent and gives ligh
5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
Explanation:
4) This exercise is asked to give some examples of thermal and electrical energy transfer
the transfer of thermal energy occurs when we grasp a hot or cold body due to the difference in temperature between the body and us there is an exchange of heat, for example when drinking a cup of hot coffee there is a transfer of energy from the cup to the hand .
If we take a can of cold soda there is a transfer from hand to can.
Electrical transfer occurs, for example, when a current passes through a light bulb, it becomes incandescent and gives light.
In all modern electrical appliances there is transformation of electrical energy
5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
For example, when you lift a box, the potential energy of the box increases with height, but the energy of the person decreases because it does work that is negative.
In amusement park rides, the energy accumulated in one part of the game generally with height is transformed into energy of movement in another part of the game, but the total energy remains constant.

Planetesmals are made from
A planetesimal is an object formed from dust, rock, and other materials. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

Marcy has two objects, X and Y. Object X looks yellow, and object Y looks black. Which statement best explains the color of the objects?
Answer:
Object X reflects yellow and object Y reflects none.
Explanation:
We are able to see the colors of different objects because the light rays falling on the surface of an object reflects back few or none of the colors to our eyes. We see the color that is reflected back to our eyes.
In the context, Marcy has two objects, X and Y. We see that object X is yellow in color because as the light rays falls on the object X, it absorbs all the colors of the spectrum and reflects the color yellow back to our eyes. So we can see that the object X is yellow.
Similarly, when spectrum light falls on the surface of the object Y, it absorbs all light in its body and reflects none of its colors. So the object Y appears to be black to our eyes.

How many molecules are in 5 moles of O2? A. 6.02 × 1024 B. 3.010 × 1024 C. 3.10 × 1024 D. 3.010 × 1023
There are b) 3.010 * 10 ^ 24 molecules in 5 moles of O2
What is mole ?
The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilograms of carbon 12 .
Number of moles = 5 moles
Number of molecules = ?
Avogadro's number = 6.022 * 10^23
Number of molecules in 5 moles of O2= number of moles * Avogadro's number
= 5 * 6.022 * 10^23
= 30. 10* 10 ^23 = 3.011 * 10 ^ 24 molecules
There are b) 3.010 * 10 ^ 24 molecules in 5 moles of O2

a balloon rubbed against denim gains a charge of -8.0 x 10^-6 c. What is the electric force between the balloon and the denim, which now has a charge of +8.0 × 10^-6 C, when the two are separated by a distance of 0.05 m?
Answer:
230.4 N
Explanation:
Applying,
F = kqq'/r²..................... Equation 1
Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' = charge in the denium, r = distance between the charges.
From the question,
Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m
Constant: k = 9×10⁹ Nm²/C²
Substitute these values into equation 1
F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²
F = (576×10⁻³)/0.0025
F = 230.4 N.

find the energy released when there is a decrease of 0.3kg of material in a nuclear reaction
Answer:
E = 2.7 x 10¹⁶ J
Explanation:
The release of energy associated with the mass can be calculated by Einstein's mass-energy relation, as follows:
[tex]E = mc^2[/tex]
where,
E = Energy Released = ?
m = mass of material reduced = 0.3 kg
c = speed of light = 3 x 10⁸ m/s
Therefore,
[tex]E = (0.3\ kg)(3\ x\ 10^8\ m/s)^2[/tex]
E = 2.7 x 10¹⁶ J
