Four 29-ohm resistors are connected in series to an ideal 10-volt battery. What is the equivalent resistance of the circuit?
Answer:
Equivalent resistance of the circuit is 116 ohm.
Explanation:
Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so
→ Equivalent resistance = R_1 + R_2 + R_3 + R_4
→ Equivalent resistance = (29 + 29 + 29 + 29) ohm
→ Equivalent resistance = 116 ohmA 3.00 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 124 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 11.9 m/s, while the spring is initially unstrained. What is the amplitude of the resulting simple harmonic motion
Answer:
[tex]A=0.185m[/tex]
Explanation:
From the question we are told that
Mass of Block [tex]M=3*10^-2kg[/tex]
Spring constant [tex]\mu=124 N/m[/tex]
Initial Speed [tex]V_1=11.9m/s[/tex]
Generally the equation for Kinetic Energy is mathematically given by
[tex]K.E=1/2 mv^2[/tex]
Therefore
[tex]K.E_1=1/2*0.03*11.9^2[/tex]
[tex]K.E_1=2.12J[/tex]
Where
[tex]Initial K.E_1=Final K.E[/tex]
Generally the equation for Final Energy stored is mathematically given by
[tex]K.E_2=0.5\mu a^2[/tex]
Therefore
[tex]K.E_1=K.E_2[/tex]
[tex]0.5\mu A^2=2.12J[/tex]
[tex]A=\sqrt{\frac{2.12}{0.5*124}}[/tex]
[tex]A=0.185m[/tex]
Therefore the amplitude of the resulting simple harmonic motion is
[tex]A=0.185m[/tex]

If all your cells were the same, could you still do everything you do now?
Explain.
Answer:
No, you couldn't function the same as you do now.
Explanation:
This is because each cell follows individual tasks, and makes up specific parts of a body. For example, if all of your cells were those of an eye, you would be missing the components of arms, legs, etc.
Answer: No
Explanation: If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.

Can you tell from an FBD if an object is moving or not? Explain your response.
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.
What do you think is the factor that causes projectile path to bend?
The movement of an object in a curved path toward the ground due to the application of a horizontal force and the downward force of gravity is projectile motion. The gravity is the factor that leads to bend of projectile path.
What is gravity?Gravity is the universal force of attraction that holds all matter together. It is by far the weakest known natural force and thus has no influence on the internal properties of everyday matter.
A projectile is an object whose main force is gravity. Because gravity is a downward force, it causes a projectile to accelerate downward.
Thus, the factor that causes projectile path to bend is gravity.

If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a __________________ on a heating curve, which occur at the __________________ and ____________________.
Answer:
1. Plateau where the temperature stays constant
2. Melting
3. Boiling points of the substance
Explanation:
The relationship between kinetic energy and temperature is given as follows;
[tex]\overline E = \dfrac{3}{2} \times \dfrac{R}{N_A} \times T[/tex]
Where;
[tex]\overline E[/tex] = The average kinetic energy of the atom
R = The universal gas constant
[tex]N_A[/tex] = Avogadro's number
T = The temperature in Kelvin
Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance
Therefore, we have;
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. plateau where the temperature stays constant on a heating curve, which occur at the 2. melting and 3. boiling points of the substance.

If V is the original volume, V' is the new volume, T is the original Kelvin temperature, and T' is the new Kelvin temperature, how is Charles's law expressed mathematically
Answer:
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]
Explanation:
Given the following data;
Original volume = V
New volume = V'
Original temperature = T
New temperature = T'
To write an expression for Charles's law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

A cell of emf 18v has an internal resistance of 3ohm . the terminal p.d of the battery becomes 15v when connected by a wire. find the resistance of the wire.
Answer:
Resistance = 15 Ohms
Explanation:
Given the following data;
Emf voltage = 18 V
Internal resistance = 3 Ohms
Potential difference = 15V
To find the resistance of the wire;
First of all, we would determine the current flowing through the wire.
Mathematically, the terminal potential difference is given by the formula;
V = E - IR
Where;
V is the terminal potential difference.
E is the electromotive force (emf).
I is the current.
R is the internal resistance.
15 = 18 - I*3
15 = 18 - 3I
3I = 18 - 15
3I = 3
I = 1 Amperes
Next, we find the resistance of the wire;
Voltage = current * resistance
Substituting into the formula, we have;
15 = 1 * resistance
Resistance = 15/1
Resistance = 15 Ohms

easy hope it helps#CARRYONLEARNING!Describe succinctly the relationship between how far a galaxy is from us (its distance), versus how fast it is moving.
Answer:
Distance is directly proportional to the velocity
Explanation:
In 1929, Edwin Hubble's wrote an article that talked about relationship between the distance and recession speed/velocity of galaxies which led to what is known as the Hubble Law. This law states that galaxies are moving away from the earth at velocities proportional to their distances.
Thus is written as;
v = H_o•d
Where;
v is velocity
d is distance
H_o is Hubble's constant rate of cosmic expansion.
He came to this conclusion by generating a graph known as Hubble's classic graph which was a graph of observed velocity vs distance for nearby galaxies.

Dish-shaped reflectors are used to steer microwaves in order to establish communications links between nearby buildings. Those reflectors are often made from metal mesh. Why don't they have to be made from solid metal sheets
A "screen" or even just a set of parallel bars are highly reflective to electromagnetic waves as long as the open spaces are small compared to the wavelengths.
"Grid" dishes work fine ... with less weight and less wind resistance ... for frequencies below about 3 GHz. (Wavelengths of at least 10 cm.)
(I even worked on a microwave system in South America where huge grid dishes were used on a 90-mile link.)

A marble block of mass 2 kg lying on ice when given a velocity of 6 m/s is stopped by a friction in 10s then what is the coefficient of friction?
Answer:
[tex]\mu=0.06[/tex]
Explanation:
Given that,
Mass of a block, m = 2 kg
Velocity of the block, v = 6 m/s
It stopped in 10 s
We need to find the coefficient of friction.
The frictional force is balanced by the opposing force such that,
[tex]\mu mg=ma\\\\\mu=\dfrac{a}{g}[/tex]
Where
a is acceleration, a = 6/10 = 0.6 m/s
So,
[tex]\mu=\dfrac{0.6}{10}\\\\\mu=0.06[/tex]
So, the coefficient of friction is equal to 0.06.
A block of aluminium of density 7900 kg/m3 has a volume of 250 cm. Find the
mass of the block.
Answer:
mass of block=2.7 gm
Explanation:
concept: Density=mass/volume
given:ρ=2700 kg/m^3 and v=250 cm^3 (in cm^3 not in m^3)
=> v= convert cm^3 to m^3
there fore= 1 cm^3=1 cm*1 cm*1 cm
i.e 1 cm^3=1/100*1/00*1/100 m^3 => 1 cm^3=1/1000000 m^3
ρ=m/v
=>mass=ρ*volume
=>mass=2700*1/10^-6
=>mass=2.7*10^-3 kg =>2.7 gm
