a. greater than the current in the battery and the ammeter.
B. There is no way to tell.
C. less than the current in the battery and the ammeter.
D. equal to the current in the battery and in the ammeter.
The current in the lamp of the series current is D. equal to the current in the battery and in the ammeter.
What is a series circuit?It should be noted that a series circuit has only one path through which current can flow. A series circuit simply comprises a path along which the whole current can flow through each component.
Since the series circuit contains a battery, an ammeter, and a lamp. The current in the lamp is equal to the current in the battery and in the ammeter. This is because in series connection the current through all the circuit elements must be the same.

The unit of density is called derived unit, why?
Answer: Density is measured in kg⋅m−2 . This means that it is derived from fundamental units which are the kilogram and metre. ... hence the kilogram and the metre are SI units and density is a derived unit from these units
Explanation:
they are calculated from the base units mass and length. Density is one derived unit; force, area, volume, specific volume and mass fraction are also derived units. Each derived unit is defined by a quantity equation.
Answer:
Density is obtained through mathematical manipulation.
Explanation:
A derived unit is obtained through mathematical calculation and the result is written with the S.I unit kg/m³
A 1.80-kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 15.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations.
(a) Find the force constant of the spring.
N/m
(b) Find the frequency of the oscillations.
Hz
(c) Find the maximum speed of the object.
m/s
(d) Where does this maximum speed occur?
x = ±
m
(e) Find the maximum acceleration of the object.
m/s2
(f) Where does the maximum acceleration occur?
x = ±
m
(g) Find the total energy of the oscillating system.
J
(h) Find the speed of the object when its position is equal to one-third of the maximum value.
m/s
(i) Find the magnitude of the acceleration of the object when its position is equal to one-third of the maximum value.
m/s2
Answer:
Explanation:
(a) Force constant = force/displacement = 15/0.2
=75 N/m
(b) For SHM with spring, the angular frequency = sqrt ( force constant / mass )
= sqrt ( 75 / 1.8 )
= 6.455
Frequency = Angular frequency / 2pi
= 1.03Hz
(c) Maximum speed is when object's potential energy is at minimum.
1/2*mass*speed^2 = 1/2*force constant*displacement^2
speed^2 = 75*0.2^2/1.8 = 1.67
speed = sqrt (1.67)
= 1.29 m/s
(d) It occurs at x=0
(e) Maximum acceleration = Force / m = 15/1.8
= 8.33 m/s^2
(f) It occurs at x=0.2m
Answer:
Explanation:
given:
The mass of the object attached to the spring: m = 1.80 kg
The magnitude of the maximum horizontal force exerted: F = 15.0 N
The amplitude of the spring-object oscillation: A = 0.200 m
a. k=15/.2=75N/m
b. (2pi*frequency)^2 = k/m = 75/1.8 = 41.67
frequency = 1.03Hz
c. max speed^2 = amplitude^2*k/m = 0.2^2 * 41.67
max speed = 1.29 m/s
d. x=0m
e. max accel = F/m = 15/1.8 = 8.33 m/s^2
f. x=0.2m
e. energy = 1/2*k*A^2
= 1/2*75*0.2^2
= 1.5J

Their teacher wants all groups to pick up at least 10 paper clips. What revisions could Bob and Sarah make to increase the number of paper clips their electromagnet picks up
1). Wrap more turns of the wire around the nail.
2). Increase the electrical current through the wire. (Do this by inserting another battery in the circuit, in series with the first one.)
An elevator is rising up a vertical shaft in a skyscraper. Between the 12th and 20th floors, it travels at a constant speed. During this time period:
1.) The only unbalanced force acting on it is air resistance.
2.) The forces acting on it are balanced so the net force is zero.
3.) The upward force is greater than the combined downward forces of gravity and air resistance, making it move upward.
4.) There are no forces acting on it so the net force is zero.

explain why the rate of diffusion of a gas decreases with decrease in temperature
Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

Please help!!A camera lens 13.3 cm from a
flower makes an image at a
distance of 2.25 cm from the lens,
on the film. What is the focal
length of the lens?
(Unit = cm)
Answer:
f=1.92 cm
If ans is correct reply for explanation.
The typical focal length formula looks as follows: 1/Focal length = 1/Image distance + 1/Object distance , where: Image distance and Object distance are given in mm.
1/f = 1/u + 1/v
1/f = 1/133 + 1/22.5
= 0.007 + 0.044
= 0.0514 mm
What is focal length ?"The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light."

A 35 g block of ice is cooled to −83 ◦C. It is added to 565 g of water in an 87 g copper calorimeter at a temperature of 22◦C. Find the final temperature. The specific heat of copper is 387 J/kg · ◦C and of ice is 2090 J/kg · ◦C . The latent heat of fusion of water is 3.33 × 105 J/kg and its specific heat is 4186 J/kg · ◦C . Answer in units of ◦C.
Answer:
Explanation:
Heat gained by ice in warming up to 0⁰C = .035 x 2090 x (83-0)= 6071.45 J
heat used up by ice to melt at 0⁰C = .035 x 3.33 x 10⁵ J = 11655 J
Heat used up in warming up water to t⁰C = .035 x 4186 x t = 146.51 t
heat released by warm water to cool from 22⁰C to t = .565 x 4186 x ( 22 - t )
=52032 -2365.1 t
heat released by copper calorimeter to cool from 22⁰C to t = .087 x 387 x ( 22 - t ) = 740.72 - 33.7 t
total heat released = 52032 -2365.1 t + 740.72 - 33.7 t
= 52772.72 - 2398.8 t
Heat lost = heat gained
52772.72 J- 2398.8 t = 6071.45 J + 11655 J + 146.51 t
2545.31 t = 35046.27
t = 13.8°C.

On the dog's return trip (between t = 10 and t = 12.5 seconds), the slope of the position function is steeper than during the first 5 seconds, which means the dog ran home faster. The only option that captures this is D.
You can check to make sure that the dog indeed runs twice as fast on the return trip. The slope of the position function during the first 5 seconds is
(change in position) / (change in time) = (5 - 0) / (5 - 0) = 5/5 = 1
while during the return trip, it is
(0 - 5) / (12.5 - 10) = -5/2.5 = -2
Ignoring the sign (which only indicates the direction in which the dog was running), we see that the dog's speed on the return trip was indeed twice as high as during the first 5 s.

22. The energy of an electromagnetic wave and it's frequency are related by the following equation:
E = hf
Where:
E => is the energy
h => is the Planck's constant
f => is the frequency
From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.
23. Gamma ray and radio wave are both electromagnetic waves. All electromagnetic waves has a constant speed of 3×10⁸ m/s in space.
Thus, gamma ray and radio wave have the same speed in space.
