Answer:
gₓ = 6.52 m/s²
Explanation:
The value of acceleration due to gravity on the surface of earth is given as:
g = GM/R² -------------------- equation 1
where,
g = acceleration due to gravity on surface of earth
G = Universal Gravitational Constant
M = Mass of Earth
R = Radius of Earth
Now, for the alien planet:
gₓ = GMₓ/Rₓ²
where,
gₓ = acceleration due to gravity at the surface of alien planet
Mₓ = Mass of Alien Planet = 2.4 M
Rₓ = Radius of Alien Planet = 1.9 R
Therefore,
gₓ = G(2.4 M)/(1.9 R)²
gₓ = 0.66 GM/R²
using equation 1
gₓ = 0.66 g
gₓ = (0.66)(9.81 m/s²)
<u>gₓ = 6.52 m/s²</u>
<span>One result of a chemical change is letter B: A
new material is formed. Let us take for example on the paper being burned to
ashes. There is a clear use of heat or thermal energy as heat is transferred
from the medium to the paper, however, no energy is created, it only
transformed to other energy. Materials may change but it could also happen to
physical change like ice (which was in solid phase) turning or evaporating to
water (liquid phase).</span>

Answer:
In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed
Explanation:
Polar vectors are the type of vector usually simply known as "vectors." In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.
Answer: Trotting uses only 75 percent of the energy as galloping
Explanation: Trotting is only 300 J/m, whereas galloping is roughly 400 J/m
