Answer:
h = 17 10⁶ m from surface of mars
Explanation:
For this exercise we will use Newton's second law where force is the force of universal gravitation
F = m a
The acceleration is centripetal
a = v² / r
G m M / r² = m v² / r
The speed module is constant, so we use the uniform motion ratio
v = d / t
Where the distance is the length of the circumference and the time is the period of the orbit
d = 2π r
v = 2π r / T
We replace
G M / r² = (4π² r² / T) / r
r³ = G M T² / 4π²
Let's reduce time to SI units
T = 24.66 h (3600 s / 1 h) = 88776 s
Let's calculate
r = ∛ 6.67 10⁻¹¹ 6.42 10²³ 88776² / 4π²
r = ∛ 8.5485 10²¹ m
r = 2,045 10⁶ m
This is the distance from the center of the planet, The height, which is the distance from the surface is
r = 
+ h
h = r -
h = 20.45 10 6 - 3.39 106
h = 17 10⁶ m
Metallic elements can exist on their own as individual atoms.
Nonmetals usually exist as molecules, combining with atoms of themselves.
Nonmetals can exist on their own as individual atoms.
Explanation:
Metallic elements can exist on their own as individual atoms without combining with another atom. They are stable that way. For example gold, copper, and silver.
Non-metals are usually found as molecules in combined states. The molecules are bounded to each other through covalent bonds. Examples are oxygen gas, nitrogen gas e.t.c. When the two atoms combine, they share their electrons to for homonuclear molecules.
Non-metals like the noble gases exists on their own as individual atoms. They are mono-atomic gases and are stable in nature.

Answer:
Kathmandu
Explanation:
As the altitude get higher, the gravitational pull of the earth on the object increases, therefore, the mass is higher up above.
Answer:
60*12.0= 720 = v/60 * 12.0 squared which is 1,728
Explanation:
Horizontal velocity component: Vx = V * cos(α)
Answer:
Explanation:
The mass of the deuteron = mass of the proton + mass of the neutron + mass equivalent of the energy of 2.2 Mev evolved.
I amu = 931 Mev
2.2 Mev = 2.2 / 931 amu
= ( 2.2 / 931 )x 1.6726 x 10⁻²⁷
= .00395 x 10⁻²⁷
The mass of the deuteron =( 1.6726 + 1.6749 + .00395)x 10⁻²⁷ kg
= 3.35145 x 10⁻²⁷ kg
b ) Momentum of gamma ray
= h / λ ( h is plank's constant and λ is wavelength of gamma ray )
= hυ / υλ ( υ is frequency of gamma ray )
= E / c ( E is energy of photon and c is velocity o light )
= 2.2 x 10⁶ x 1.6 x 10⁻¹⁹ J / 3 x 10⁸
= 1.173 x 10⁻²¹ Kg m /s
This will be the momentum of deuteron also
Kinetic energy
= p² / 2m ( p is momentum and m is mass of deuteron )
= ( 1.173 x 10⁻²¹ )² / ( 2 x 3.35145 x 10⁻²⁷)
= 1.376 x ⁻¹⁵ J
Energy of gamma ray
= 2.2 x 10⁶ x 1.6 x 10⁻¹⁹ J
= 3.52 x 10⁻¹³ J
So kinetic energy of deuteron is smaller than energy of gamma ray photon .
