Eiman connects eight 12Ω lamps in series. What is
the total resistance of the circuit?
please help
Answer:
Total resistance is 96 ohm
Explanation:
Rs = R1 +R2 + R3 + R4 + R5 +R6 + R7 + R8
where R1 is lamp 1
R2 is lamp 2 n so on
Rs = 12 + 12 +12 + 12 +12 + 12 + 12 + 12( as each lamp is of resistance 12)
Rs = 96 ohm

Which of the following shows a balanced nuclear reaction?
Answer:
No. 2
Explanation:
The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

How do we know when an object is in static or dynamic equilibrium?
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.Can someone help me answer this question what type of rock will form in this type of environment.

A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the density of lead.
Answer:
11.3 g/cm^3
Explanation:
density = mass/volume
volume of rectangular prism = length * width * height
volume = (4.50 cm)(5.20 cm)(6.00 cm) = 140.4 cm^3
mass = 1587 g
density = (1587 g)/(140.4 cm^3)
density = 11.3 g/cm^3

Explain the benefits of understanding sound waves properties in real life.
Answer:
The vibrations from sound waves cause our ears to send signals to our brains to create sound. The speed of sound waves will determine the sound's pitch, or how high or low something sounds. Sound waves are important because they allow us to hear important messages and emergency signals to protect ourselves.

If you were in charge of designing a wire to carry electricity across your city, state or province, which of
the following properties would be most important for your wire to have?
Should it be thick or thin, aluminum or nichrome, buried underground or installed out in the sun
Pleaseeee I need this done I beg Ill give brainiest and make sure its at least on paragraph if not then at least as many sentences as you can please
Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.

Answer:
1.F = 256 N
2.a = 8 m/s/s
By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.
F = ma
256 N = m * 8 m/s/s
m = 256 N/8 m/s/s

The diagram below shows a wave. The feature of the wave are labeled A, B, C, and D. Which label identifies the wavelength?
According to the given diagram, the c identifies the wavelength of the curve. Hence, option C is correct.
What is wavelength?In order to characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10-9 nanometers (nm) or angstroms (10-10 m) are more usually used.
The relationship between frequency and wavelength is inverse, with frequency being the number of wave cycles per second. A signal's wavelength shortens as its frequency rises, or we may say that the relationship between wavelength and refractive index is inverse.

Sally's mass on Earth is 50 kg. What is her mass on the moon?
Answer:
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
does this help
Sally's mass on Moon is: C. 50 kg
Mass is a measure of the amount of matter that an object or a body is typically made up of. The standard unit of measurement for the mass of an object is kilograms (kg).
Regardless of the location of a person, an object at any given time, mass (amount of matter that they're made up of) is always the same i.e constant.
This ultimately implies that, whether you're on the Moon, space, planet Earth or any other place; your mass would always remain the same or constant.
In this scenario, Sally's mass on Earth is 50 kg. Thus, we can deduce that her mass on Moon would be 50 kg.
