Explanation:
The classic model of a black body made predictions of the emission at small wavelengths in open contradiction with what was observed experimentally, this led Planck to develop a heuristic model. This assumption allowed Planck to develop a formula for the entire spectrum of radiation emitted by a black body, which matched the data.
As the ship is not in motion compared with passengers on the ship so
it will be
a lighthouse on a nearby island
so correct answer will be C

Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
<h3>What is impulse?</h3>
Impulse is simply the product of force and time.
Using the formula of impulse.
Ft = m( v - u )
Given the data in the question;
- Initial velocity v = 25m/s
We substitute our values into the expression above.
Ft = m( v - u )
Ft = 1800kg( 25m/s - 0m/s )
Ft = 1800kg × 25m/s
Ft = 45000kgm/s
Therefore, Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
