Answer:
Impulse = 48 kg m/s
Gain in momentum = 48 kg m/s
Explanation:
Force (F) = 6N
Time (t) = 8
Mass (m) = 3 kg
Final velocity (v) = ?
Initial velocity (u) = 0 m/s
First, find acceleration
F = m * a
a = F / m
a = 6 / 3
a = 2 m/s^2
Now, find final velocity
v = u + a * t
v = 0 + 2 * 8
v = 16 m/s
Now, find impulse
Impulse = change in momentum
Impulse = final momentum - initial momentum
Impulse = m * v - m * u
Impulse = m ( v - u )
Impulse = 3 ( 16 - 0 )
Impulse = 48 kg m/s
Here, gain in momentum is same as impulse.
Answer:
there are 24 time zones
Explanation:
each time zone is roughly 15°apart
Planck find the correct curve for the specturm of light emitted by a hot object by vibrational energies of the atomic resonators were quantized.
<h3>Briefing :</h3>
- The energy density of a black body between λ and λ + dλ is the energy E=hc/λ of a mode times the density of states for photons, times the probability that the mode is occupied.
- This is Planck's renowned equation for a black body's energy density.
- According to this, electromagnetic radiation from heated bodies emits in discrete energy units or quanta, the size of which depends on a fundamental physical constant (Planck's constant). The basis of infrared imaging is the correlation between spectral emissivity, temperature, and radiant energy, which is made possible by Planck's equation.

Answer:
Electric and magnetic fields:
Maxwell's equations tell us that
a changing magnetic field creates a changing electric field and
a changing electric field creates a changing magnetic field
Answer:
A soma dos dois tipos de energia, potencial e cinética, resultam na energia mecânica. Ou seja, ambas compõe a energia mecânica.
