Think about a time when you walked down an empty hallway
and heard the echo of your footsteps. Write what you think
caused the echo.
Answer:
Explanation:
There are a few conditions as mentioned: "you walked down an empty hallway and heard the echo of your footsteps." So first thing is as you walk, your shoes touch the floor and make noises. Those are sounds of your footsteps. You are in a hallway so the sounds are trapped within the hallway. It is empty so there is nothing like people who would block and absorb the sounds. With sounds bouncing around walls and floor of the hallway, they bounce back to the source: you. That is when you hear the echo of your footsteps.
A man tries to push a 200 kg Car that moves at a acceleration 0.50 m/s2. The man is able to displace the car 10 m. How much work did he do?
The work done by the man pushing the car over the given distance is 1000J.
Given the data in the question;
Mass of car; [tex]m = 200kg[/tex]Acceleration of the car; [tex]a = 0.5m/s^2[/tex]Distance covered by the car; [tex]d = 10m[/tex]Work done; [tex]W = \ ?[/tex]
Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;
[tex]Work\ done = f * d[/tex]
Where f is force applied and d is distance travelled.
To determine the work done by the man, we first solve for the force applied F.
From Newton's Second Law; [tex]Force \ F = m * a[/tex]
We substitute our given values into the expression
[tex]F = m * a \\\\F = 200kg * 0.5m/s^2\\\\F = 100kg.m/s^2[/tex]
Next we substitute our values into the expression of work done above.
[tex]Work \ done = f * d\\\\Work \ done = 100kg.m/s^2 * 10m\\\\Work \ done = 1000kgm^2/s^2\\\\Work \ done = 1000J[/tex]
Therefore, the work done by the man pushing the car over the given distance is 1000J.

A small car with mass of 0.800 kg travels at a constant speed
on the inside of a track that is a vertical circle with radius 5.00
m. If the normal force exerted by the track on the car when it
is at the bottom of the track is 25 N,
a) What is the normal force on the car when it is at the (i)
top, (ii) rightmost and (iii) leftmost point of the track?
b) What is the speed of the car as it travels around the
vertical circle?
Answer:
The equation of equilibrium at the top of the vertical circle is:
\Sigma F = - N - m\cdot g = - m \cdot \frac{v^{2}}{R}
The speed experimented by the car is:
\frac{N}{m}+g=\frac{v^{2}}{R}
v = \sqrt{R\cdot (\frac{N}{m}+g) }
v = \sqrt{(5\,m)\cdot (\frac{6\,N}{0.8\,kg} +9.807\,\frac{kg}{m^{2}} )}
v\approx 9.302\,\frac{m}{s}
The equation of equilibrium at the bottom of the vertical circle is:
\Sigma F = N - m\cdot g = m \cdot \frac{v^{2}}{R}
The normal force on the car when it is at the bottom of the track is:
N=m\cdot (\frac{v^{2}}{R}+g )
N = (0.8\,kg)\cdot \left(\frac{(9.302\,\frac{m}{s} )^{2}}{5\,m}+ 9.807\,\frac{m}{s^{2}} \right)
N=21.690\,N
1. manganese dioxide is used in dey cell . ( Give reason)
2. Fuses are used in a circuit. ( Give reason )
Answer:
1.In dry cells, manganese dioxide acts as a ‘depolariser'.
In the depolarization process, the depolariser is used to remove hydrogen and doesn't allow the voltage to get reduced due to polarisation of the cell . Manganese oxide was used as a depolariser in Leclanché cell .
In zinc-carbon dry cell, the manganese dioxide takes in electrons as it is converted to Manganese III oxide (Mn2O3)
2.The fuse breaks the circuit if a fault in an appliance causes too much current flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

Calculate the average force with which the Sun pulls the Earth. It will help to know
that rsun_Earth = 9.4E9 m.
Answer:
7.9 x 10^21 pound-force
Explanation:
The average distance between the Earth and sun is 150 trillion meters, or 1.5 x 10^11 meters. The mass of the sun is 1.99 x 10^30 kilograms, while the Earth weighs in at 6.0 x 10^24 kilograms. The gravitational constant is 6.67 x 10^-11 meter^3 / (kilogram - second^2). So the Earth and sun pull on each other with a force equal to 3.52 x 10^22 newtons. The newton is a unit of force equal to a kilogram-meter/second^2. One newton is equal to 0.22 of the rarely used English unit called pound-force, so 3.52 x 10^22 newtons is 7.9 x 10^21 pound-force.

If the electric potential in a region is given by v(x)=7/x2 the x component of the electric field in that region is
Hi there!
Recall that:
[tex]\Delta V = -\int\limits^a_b {E \cdot } \, dx[/tex]
Given an electric field, the potential difference can be solved by using integration. Similarly:
[tex]E = -\frac{dV}{dx}[/tex]
We can differentiate the electric potential equation to solve for the electric field.
Use the power rule:
[tex]\frac{dy}{dx} x^n = nx^{n - 1}[/tex]
Differentiate the given equation.
[tex]-\frac{dV}{dx}\frac{7}{x^2} =- \frac{dV}{dx}7x^{-2} = -(-14x^{-3}) = \frac{14}{x^3}[/tex]
Or:
[tex]\boxed{E(x) = \frac{14}{x^3}}[/tex]
The component of the electric field in that region is E = 14/x³ if the electric potential in a region is given by v(x)=7/x2
What is an electric field?An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
We have:
The electric potential in a region is given by:
[tex]\rm V(x) = \frac{7}{x^2}[/tex]
We know the relation between potential difference and an electric field is given by:
[tex]\rm \triangle V = \int\limits^a_b {E.} \, dx[/tex]
If the electric field is given, then:
[tex]\rm E = -\frac{dV}{dx}[/tex]
[tex]\rm E = -\frac{d(7x^{-2} )}{dx}[/tex]
After differentiate:
[tex]\rm E = -(-14x^{-3})[/tex] or
[tex]\rm E = \frac{14}{x^3}[/tex]
Thus, the component of the electric field in that region is E = 14/x³ if the electric potential in a region is given by v(x)=7/x2

If a FM radio station broadcasts at 80. 3 MHz (megahertz), what is its wavelength in m (speed of light 3. 0 x 108 m/s)
Answer:
Wavelength = 3.74 m
Explanation:
In order to find wavelength in "metres", we must first convert megahertz to hertz.
1 MHz = 1 × 10⁶ Hz
80.3 Mhz = x
x = 80.3 × 1 × 10⁶ = 8.03 × 10⁷ Hz
The formula between wave speed, frequency and wavelength is:
v = fλ [where v is wave speed, f is frequency and λ is wavelength]
Reorganise the equation and make λ the subject.
λ = v ÷ f
λ = (3 × 10⁸) ÷ (8.03 × 10⁷)
λ = 3.74 m [rounded to 3 significant figures]

Calculate the range of wavelengths that are received by the radio in a car. Suppose that the range of frequencies of FM radio is 88.0 MHz to 108 MHz.
The range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.
To find the range of wavelengths, we use the equation for the speed of a wave
Speed of a waveThe speed of a wave v = fλ where
f = frequency and λ = wavelengthWhat is Wavelength?This is the distance a wave travels in one cycle of the wave.
Making λ subject of the formula, we have
λ = v/f
Given that the range of frequencies of FM radio is 88.0 MHz to 108 MHz and
v = speed of electromagnetic wave = 3 × 10⁸ m/s, f' = lowest frequency = 88.0 MHz = 88.0 × 10⁶ Hz and f" = highest frequency = 108 MHz = 108 × 10⁶ HzThe longest wavelength, λ'λ' = v/f'
= 3 × 10⁸ m/s ÷ 88.0 × 10⁶ Hz
= 0.0341 × 10² m
= 3.41 m
The shortest wavelength, λ"λ" = v/f"
= 3 × 10⁸ m/s ÷ 108 × 10⁶ Hz
= 0.0278 × 10² m
= 2.78 m
So, the range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.

Explanation:
Beluga
Answer:
Explanation:
It depends on whether this is a "trick" question.
The law of universal gravitation says that the attractive force between two objects depends directly on their masses and inversely to the square of distance in between them.
As the objects in A are bigger than B, they MAY have higher masses. So the force is larger in A.
But no information is given about object mass or density. The distance between objects in B is shorter. So if the objects in B have the same masses those in A, then the force is larger in B.
