Gravitational force (F) is given by:
F ∝ (m1 * m2) / r²
If both masses (m1 and m2) are halved:
New force F' ∝ ((m1/2) * (m2/2)) / r²
F' ∝ (m1 * m2) / (4 * r²)
F' = F / 4
The gravitational force becomes one fourth.
Let the two consecutive odd numbers be x and x + 2.
Given x² + (x + 2)² = 394:
x² + x² + 4x + 4 = 394
2x² + 4x - 390 = 0
x² + 2x - 195 = 0
(x + 15)(x - 13) = 0
x = -15 or x = 13
For x = 13, the numbers are 13 and 15.
13² + 15² = 169 + 225 = 394
The sum of the numbers is 13 + 15 = 28.
Given 2x - 6 = 0:
2x = 6
x = 6/2 = 3
To find 3/7 of 14:
(3/7) * 14 = 3 * 2 = 6
Given x³ = 64:
x = ∛64 = 4 (since 4³ = 64)
The question seems to be asking for the value of x.
The correct answer is 4.
"Put away" means to save or store something, especially money, for future use.
The phrase fits the context of preparing financially for difficult times.
Work done (W) is calculated as:
W = F * d * cos(θ)
where F is the force, d is the displacement, and θ is the angle between the force and displacement.
For work done to be zero, cos(θ) needs to be 0, which happens when:
θ = 90°
Hydrogen bonding occurs when hydrogen is bonded to highly electronegative atoms like fluorine, oxygen, or nitrogen.
HCl does not form hydrogen bonds because chlorine is not electronegative enough to form such interactions with hydrogen.
"Say to us" changes to "tell us", and present tense remains as it's a universal statement.
"You" changes to we, and "our" to their to match the speaker and listener perspective.
“Could” is used to express ability in the past.
The correct sentence is: "He could sing high notes when he was young but his voice has changed."
