The box is accelerated from rest to 4 m/s in a matter of 2.5 s, so its acceleration <em>a</em> is such that
4 m/s = <em>a</em> (2.5 s) → <em>a</em> = (4 m/s) / (2.5 s) = 1.6 m/s²
Then the force applied to the box has a magnitude <em>F</em> such that
<em>F</em> = (10 kg) (1.6 m/s²) = 16 N
I'm assuming it was to keep the data consistent? The further you are from a heat source the less heat will get to you as the temperature tries to reach equilibrium and the waves start to spread out, so you should keep everything the same distance to get consistent results. I don't have any information so this is just my assumption
Answer:
C
Explanation:
The total kinetic energy is the sum of the kinetic energy in the center of mass (Rotational Kinetic energy) plus the kinetic energy of the center of mass( Translational Kinetic Energy).
The formula
is applicable only when
The moment of inertia must be taken about an axis through the center of mass.
Answer:
it traveled 1350 kilometers or 839 miles
Explanation:
You just have to do 450 times three because its 3 HOURS and 450 kilometers per HOUR.
Capacitance,C is equal to epsilon times area of the plate divided by distance. The permittivity of air is 8.84 x 10-12 F/m. Capacitance is equal to 2.66 x10^14 F. The energy is equal to 0.5* C*V^2. Substituting, the energy is equal to 0.5* <span> 2.66 x10^14 F * 6^2 V^2 or equal to 4.80 x10^15 W.</span>
