An object is 10 m above Earth’s surface, and has a potential energy of 490 joules. What is the object’s mass?
Explanation:
Taking g=10m/s²
P.E= mgh
490J= m×10×10.
490J=100m
m. = 490J/100
m. =4.9kg
Why do we add the masses together after that inelastic collision?
Answer:An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). A collision in which the objects stick together is sometimes called perfectly inelastic because it reduces internal kinetic energy more than does any other type of inelastic collision.People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.

What is the momentum of a 750-kg Volkswagen Beetle when at rest? Value: Unit:
Answer:
p = 0
Explanation:
Given that,
Mass of beetle, m = 750 kg
It was rest. It means its speed is equal to 0.
The momentum of an object is equal to the product of mass and velocity. So,
p = mv
p = 750 × 0
p = 0 kg-m/s
So, the momentum of the beetle is 0 kg-m/s.

state two possible changes that cause a larger e.m.f to be induced
There are therefore three ways an emf can be induced in a loop: Change the magnetic field. Change the area of the loop. Change the angle between the field and the loop.
As the area decreases, the magnetic flux will also be decreased. As a result, the induced emf will be increased.
What is meant by induced emf ?Whenever the magnetic flux associated with a circuit is changed, an emf will be induced in it. This is called induced emf.
Here,
The value of induced emf is the rate of change of magnetic flux.
So, the induced emf,
ε = -dФ/dt
The negative sign indicates that the induced emf always opposes the change in flux.
Magnetic flux, Ф = NBA cosθ
So, ε = d(NBA cosθ)/dt
There are certain changes that can cause a larger emf to be induced:
1) By decreasing the magnetic field in the conductor.
As the magnetic field in the conductor decreases, the magnetic flux associated with it also decreases.
Therefore, according to Lenz's law, the induced emf will be increased.
2) By decreasing the area of cross-section of the conductor.
As the area decreases, the magnetic flux will also be decreased. As a result, the induced emf will be increased.
Hence,
As the area decreases, the magnetic flux will also be decreased. As a result, the induced emf will be increased.

Why do temperatures on the moons surface vary ncyb more than temperatures on earth
The moon has a lord density than earth
The moons surface has more craters than earth
The moon has no atomsphere
The moon is farther from the sun compared to earth
Answer:
The moon has no atmosphere
Explanation:
The temperatures on the surface of the Moon vary much more than those on Earth because the moon has no atmosphere (third answer in the list), and therefore there are no molecules that could retain residual heat and make the change from day to night a softer transition.

30. A duck flying due east passes over Atlanta, where the magnetic field of Earth is 5.0 x 10-5 T directed north. The duck has a positive charge of 4.0 x 10-8 C. If the magnetic force acting on the duck is 3.0 x 10-11 N upward, what is the duck's velocity?
Answer:
5 m/s
Explanation:
hope it helps:) u're welcome
The velocity of the duck must be 15 m/s towards the east which is explained below.
Magnetic force:The force on a moving charge with some velocity under a magnetic field is given by:
F = qv×B
here q is the charge on the object
v is the velocity of the object
B is the magnetic field
v×B gives the direction of the force
B is towards the north, and Force is directed upwards, then velocity v should be towards the east.
3×10⁻¹¹ = 4×10⁻⁸× v × 5×10⁻⁵
v = 15 m/s

Collate the electrical force between and electrons and protons in an atom that are separated by distance of 5.9 e -11m
Answer:
The electrical force between the electrons and protons in the atom is 6.62 x 10⁻⁸ N.
Explanation:
Given;
distance between the electron and proton, r = 5.9 x 10⁻¹¹ m
charge of electron, q₁ = -1.6 x 10⁻¹⁹ C
charge proton, q₂ = +1.6 x 10⁻¹⁹ C
The electric force between the two particles is calculated by Coulomb's law;
[tex]F = \frac{k|q_1|q_2|}{r^2} \\\\F = \frac{(9\times 10^9) \times (1.6\times 10^{-19})^2}{(5.9\times 10^{-11})^2} \\\\F = 6.62 \times 10^{-8} \ N[/tex]
Therefore, the electrical force between the electrons and protons in the atom is 6.62 x 10⁻⁸ N.

One of the most prominent legacies of the games is Centennial Olympic Park in the heart of Atlanta. The 21-acre plaza glistens in what was an area of urban decay, and children run and linger in the fountain.
Harvey Newman, a professor of public policy at Georgia State University, says the park brought economic development downtown.
"The area surrounding the park has added major hotels, condominiums, new office structures and, of course, people continue to flock to enjoy the Olympic rings fountain," Newman says.

A string can withstand a force of 135 N before breaking. A 2.0 kg mass is tied to the string and whirled in a
horizontal circle with a radius of 1.10 m. What is the maximum speed that the mass can be whirled at before
the string breaks?
The mass would have centripetal acceleration a given by
a = v ² / R
where
v = tangential speed of the mass
R = length of the string
By Newton's second law, a maximum tension of F = 135 N would apply an acceleration of
135 N = (2.0 kg) a → a = 67.5 m/s²
which requires a tangential speed v of
67.5 m/s² = v ² / (1.10 m) → v = √((67.5 m/s²) (1.10 m)) ≈ 8.62 m/s

what is the mass of 3 m3 of a substance having density 1200 kg/m3
Answer:
3600 kg
Explanation:
From the question,
Density = Mass/Volume
D = M/V.............................. Equation 1
Where D = Density of the substance, M = mass of the substance, V = Volume of the subtance.
Make M the subject of the equation
M = D×V ............................ Equation 2
Given: D = 1200 kg/m³, V = 3 m³.
Substitute these values into equation 2
M = 1200×3
M = 3600 kg.
Hence the mass of the substance is 3600 kg
