The dimensions for force are the product of mass and length divided by time squared. Newton's second law states that force equal s the product of mass and acceleration. What are the dimensions of acceleration?
1 answer:
Answer:
L/T^2.
Explanation:
Dimensional analysis is defined as the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, temperature etc.) and units of measure (such as miles vs. kilometers, pounds vs. kilograms etc.).
F = m * a
kg(m/s^2) = kg * a
In dimensions,
a = L/T^2.

Answer:
3.72 kJ
Explanation:
QH = 6.45 kJ
TH = 520 K
Tc = 300 K
Qc = ?
By use of Carnot's theorem
Qc / QH = Tc / TH
Qc / 6.45 = 300 / 520
Qc = 3.72 kJ
Given:
Answer:
Explanation:
As we know that the displacement of the particle from the mean position is 1/5 times of its amplitude
so we have
so now we have
now we have
so the phase other particle in opposite direction is given as
so we have phase difference given as
