2*3.5 = 7m/s
You need to multiply the acceleration by the time (which must both be in seconds; if not, convert them to the same units).
Answer:
The kinetic energy is higher for the first cart.
Explanation:
For the second cart, its mass is 2kg and the momentum measured is 10kg m/s, which leads to

resulting in
.
Consequently, the kinetic energy for the 3kg cart ends up as



indicating it is less than that of the 1kg cart so it follows that the first cart possesses greater kinetic energy.
The response is outlined below. Audio power amplifiers are present in various sound systems, including those for sound reinforcement, public addresses, home audio, and musical instrument amplifiers like those for guitars. This component is the final electronic element in the audio playback chain before signals reach the loudspeaker. To achieve the loudest possible sound, it is essential to maximize output while maintaining high input and low output impedance.
Answer: The result to the query is 0.25 ohms
Explanation:
R = u x/A.......1
where u represents the resistivity of the
rod, A is the cross-sectional area, and x denotes
the length of the rod.
Let R* represent the resistance across the adjacent sections of the rod.
Then, R* = u1/4.......2
By comparing equation 1 with equation 2, we find that
R* = 1/4
which equals 0.25 ohms.
