Answer:
a) v = √(GM/R), b) K = ½ G m M /R and d) T = 2π R√(R/GM)
Explanation:
This problem should use the law of universal gravitation
F = G m M / r²
a) For this part we use Newton's second law where acceleration is centripetal
F = m a
Centripetal acceleration is
a = v² / r
F = m v² / r
G m M / r² = m v² / r
G M / r = v²
We use the distance (R) measured from the center of the planet
v = √(GM / R)
b) the expression for kinetic energy is
K = ½ m v²
K = ½ m G M / R
K = ½ G m M / R
d) as the velocity module is constant, we can use the equation and uniform motion
v = d / T
T = d / v
The distance is the length of the circle
d = 2π R
T = 2π R / √(GM / R)
T = 2π R √ (R / GM)
whole process of the mobile phones energy transfers is almost like big cycle; Charge the battery > Battery contains chemical energy which transfers electrical energy into the phone, powering it and also transferring Light energy, Sound energy and Heat energy.
Answer:
Tips for Balancing Chemistry Equations You may only put numbers in front of the molecules. You can never alter the subscript, as it would alter the formula. ... Begin by counting and making note of the elements present on each side of the equation. Count the number of molecules of each element on both sides of the equation. More items...
