The weight of an abject is equal to its gravitational force!
Explanation:
Answer:
[tex]F_{g} = \frac{m}{d^{2} }[/tex] shows the relationship between gravity and mass.
Explanation:
According to the Newton's law of gravitation, the gravitational force between two bodies is,
[tex]F_{g} = G.\frac{m_{1}.m_{2} }{d^{2} }[/tex]
here [tex]m_{1} and m_{2}[/tex] are masses, d is distance between them.
What is Newton's law of Gravitation ?It states that gravitational force acting two bodies is directly proportional to the product of masses and inversely proportional to the square of the distance between them.
In above formula ,
If [tex]m_{1} = 1 and[/tex] [tex]m_{2} = m[/tex]
so [tex]F_{g} = G \frac{m}{d^{2} }[/tex]
Since G is constant ,
[tex]F_{g}[/tex] ∝[tex]\frac{m}{d^{2} }[/tex]
Hence second option is correctly showing relationship between gravity and mass.

When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
14.4m/s
Explanation:
To calculate the final velocity (V), we use the formula:
v = u + at
Where; v = final velocity (m/s)
u = initial velocity (m/s)
a = acceleration (m/s²)
t = time (s)
According to the provided information in this question, v = ?, u = 0m/s, a = 1.8m/s², t = 8s
Hence, v = u + at
v = 0 + (1.8 × 8)
v = 0 + 14.4
v = 14.4m/s
Therefore, his final velocity at the end of those 8 seconds is 14.4m/s.

how is the atmospheric pressure detected
Answer:
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.
An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.
Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.

To understand the origin of the torque on a current loop due to the magnetic forces on the current-carrying wires.
This problem will show you how to calculate the torque on a magnetic dipole in a uniform magnetic field. We start with a rectangular current loop, the shape of which allows us to calculate the Lorentz forces explicitly. Then we generalize our result. Even if you already know the general formula to solve this problem, you might find it instructive to discover where it comes from.
a) Give a more general expression for the magnitude of the torque τ. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m. Define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ϕ, noting that this angle is the complement of angle θ in Part A.
Give your answer in terms of the magnetic moment m, magnetic field B, and ϕ.
Answer:
The torque is [tex]\tau = B * m sin(\phi )[/tex]
Explanation:
Generally when current flow through a rectangular loop the magnetic dipole generated we can denote this as [tex]\vec m[/tex]
Here k is the length of the side of one side of the rectangular loop
Now when this loop is place in a magnetic field, the torque it experience is mathematically represented as
[tex]\vec \tau = \vec B \ X \ \vec m[/tex]
Here X stands for cross - product
From the question we are told that the angle between the vector ( [tex]\vec m[/tex])perpendicular to the plane of the coil and magnetic field(B) as [tex]\phi[/tex]
So
=> [tex]\tau = B * m sin(\phi )[/tex]

A toy car, initially travelling in a straight line at 30.0 cm/s, slows down with a constant linear acceleration of 3.0 cm/s2. How much time passes before the toy car comes to a halt?
Answer:
The toy car stops after 10 seconds.
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes uniformly at a rate called acceleration.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at\qquad\qquad [1][/tex]
The toy car moves at vo=30 cm/s and decelerates at [tex]a=-3\ cm/s^2[/tex]. Note the negative sign of the acceleration that indicates the speed is decreasing over time.
We need to calculate the time needed for the toy car to stop vf=0.
To find the time, we solve [1] for t:
[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]
Since all the units of speed and acceleration are in centimeters, we don't need to convert to meters
[tex]\displaystyle t=\frac{0-30}{-3}=10[/tex]
The toy car stops after 10 seconds.

The inertia of an object depends on its
Answer:
Inertia of an object depends on the mass of the object.
Explanation:
Inertia is the property that is possessed by a matter( anything that has weight and occupies space) that enables it to be at rest or in a state of continuous uniform motion.
The inertial of a body is the resistance that is present in the body, that forces acting on the body have to overcome for the body to move or continue moving.
The inertia of a body depends on the mass of such a body, which is directly proportional. The mass of an object is the measure of inertia, the bigger the mass of an object the bigger the inertia.
Therefore the Inertia of an object is largely dependent on the mass of such an object.

The equation Upper E equals StartFraction 1 Over 2 pi epsilon Subscript 0 EndFraction StartFraction q d Over z Superscript 3 EndFraction is approximation of the magnitude of the electric field of an electric dipole, at points along the dipole axis. Consider a point P on that axis at distance z = 23.00d from the dipole center (d is the separation distance between the particles of the dipole). Let Eappr be the magnitude of the field at point P as approximated by the equations below. Let Eact be the actual magnitude. What is the ratio Eappr /Eact?
Answer:
E_aprox = 1.003 E_real
Explanation:
In this exercise we are given the expression for the electric field of a dipole in the axis direction of the dipole
E_real = k 2q d / √(z² + d²)³
I think your equation has some errors.
In this case they indicate that d is the separation of the charges of the dipole
in the case of z »d this equations approximates
E_aprox = k 2q d/ z³
calculate the value for the two cases
E_real = k2q d / √[ ((23d)² + d²)³]
E_real = k2q d / d³ 12201
E_real = k2q 1/12201 d²
E_aprox = k2q d / (23.00d)³
E_aprox = k2q 1/12167 d²
the error between these quantities is
E_aprox / E_real = 12201 d² / 12167 d²
E_aprox / E_real = 1.003
E_aprox = 1.003 E_real
