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>
i believe your looking for this word ?? "fundamental".
Answer:
★ In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies.

Answer:
12.99 Hz
Explanation:
Resonance is said to occur in an RLC circuit when maximum current is obtained from the circuit. Hence at resonance; XL=XC and Z=R.
XL= inductive reactance, XC= capacitive reactance, Z= impedance, R= resistance
The resonance frequency is given by;
fo= 1/2π√LC
L= 3×10^-3 H
C= 0.05 F
π= 3.142
Substituting values;
fo= 1/2×3.142√3×10^-3 × 0.05
fo= 12.99 Hz
Therefore the resonance frequency of the RLC circuit is 12.99 Hz
