Answer:
The final kinetic energy of the two-car system is 60,000 J.
Explanation:
Given;
mass of the car, m = 1200 kg
time of motion, t = 8.8 s
final velocity of the car, v = 10 m/s
Apply the principle of conservation of kinetic energy; the initial kinetic energy is equal final kinetic energy.
Therefore, the final kinetic energy of the two-car system is 60,000 J.
Answer:
solved
Explanation:
From the FBD in the attachment we can write that
N+ 80 sin37°= mg
N= 46×g-80×sin37=498.94 N
also, ma= 80×cos37°
a= 80×cos37°/46= 1.3889 m/s^2
also, 10m = 0.5at^2
put a= 1.3889 m/s^2
t= 2.095 secs
d) the speed v =at
v= 1.3889*2.095= 2.91 m/s^2
(a) The wavelength of the wave for the fundamental mode is 2.4 m.
(b) The fundamental frequency of the wave is 2,708.33 Hz.
<h3>Wavelength of the wave for fundamental mode</h3>
The wavelength of the wave for the fundamental mode is calculated as follows;
Node to Node, N → N = λ/2
L = λ/2
λ = 2L
λ = 2 x 1.2
λ = 2.4 m
<h3>Fundamental frequency of the wave</h3>
The fundamental frequency of the wave is calculated as follows;
f = v/λ
f₀ = v/2L
f₀ = (6500)/(2 x 1.2)
f₀ = 2,708.33 Hz
The diagram of the wave for the fundamental mode is in the image uploaded.

Answer:
<h2>150 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 10 × 15
We have the final answer as
<h3>150 kg.m/s</h3>
Hope this helps you
They are both good conductors if both heat and electricity due to the sea of delocalized electrons that is floating around without getting bonded to an atom.
Such electrons can flow around freely to conduct heat and electricity.
