Answer:
force, mass, and acceleration
Explanation:
According to Newton's 2nd law, the acceleration of an object depends on the net force and the mass of the object. The equation for the 2nd law is Force = mass * acceleration.
Answer:
(A)8,421.1 V/m
(B)
(C)
(D)
Explanation:
area (A) = 7.6 cm^{2} = 0.00076 m^{2}
distance (d) = 1.9 mm = 0.0019 m
potential difference (v) = 16 V
(A) electric field (E) = Δv / d = 16 / 0.0019 = 8,421.1 V/m
(B) capacitance = (∈₀A)/d
where ∈₀ = permitivity of free space =
capacitance = 
capacitance (C) =
(C) charge (q) = C x v =
=
(D) surface charge density = charge (q) / area =
/ 0.00076 =
Answer:
Period T = 0.5 s
Frequency F = 2 Hz
Wave speed V = 4 m/s
Explanation:
Given that the
Number of oscillations = 30
Time taken = 15 seconds
The distance between two consecutive crests is called wavelength
Wavelength = 2m
Period is the ratio of time and the number of oscillations
Period T = 15/30 = 0.5 seconds
Frequency F is the reciprocal of period. That is,
F = 1/T
F = 1/0.5 = 2Hz
Wave speed V is the product of frequency and wavelength
V = 2 × 2 = 4m/s
