Answer:
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
The light bulb would glow brighter.
<h3>What is Resistance?</h3>
a force that works against a body's direction of motion and seeks to stop or slow down motion, such as friction. a measure of how much a material prevents an electric current from flowing as a result of a voltage.
What is the law of resistance?
Resistance and Ohm's Law. According to Ohm's law, the resistance of the circuit and the current or energy travelling through the resistance are both exactly proportional to the voltage or potential difference between two places.
The current would grow since it is exactly proportionate to the voltage, increasing the light bulb's brilliance, or simply making it brighter.

<h2>
Horizontal component of the rock’s velocity when it strikes the ground is 17.25 m/s</h2>
Explanation:
In horizontal direction there is no acceleration or deceleration for a rock projected at an initial angle of 37° off the ground.
So the horizontal component of velocity always remains the same.
Horizontal component of velocity is the cosine component of velocity.
Initial velocity, u = 21.6 m/s
Angle, θ = 37°
Horizontal component of velocity = u cosθ
Horizontal component of velocity = 21.6 cos37
Horizontal component of velocity = 17.25 m/s
Since the horizontal velocity is unaffected, we have
Horizontal component of the rock’s velocity when it strikes the ground = 17.25 m/s
