A 30 N crate is submerged in water. The amount of buoyant force acting on the crate is 25 N. What will the crate do?
The crate will float and accelerate upwards. The only force acting on the crate is the buoyant force, and it acts upwards on the crate.
The crate will sink and accelerate downwards. The only force acting on the crate is the buoyant force, and it acts downwards on the crate.
The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate.
The crate will sink and accelerate downwards. The buoyant force and the gravitational force are both acting downwards on the crate, making it accelerate down.
is it the first one?
The answer is "The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate."
Grace is correct, it's "The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate"
No, the correct answer is the third option: "The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate."
To understand why, let's break it down:
The buoyant force is the force exerted by a fluid (in this case, water) on an object that is submerged in it. It acts in the opposite direction to the force of gravity. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the object. So, in this case, the buoyant force acting on the crate is 25 N.
The weight of the crate, which is the force of gravity acting on it, is given as 30 N. Since the buoyant force (25 N) exerted on the crate is smaller than the weight (30 N) of the crate, the crate will experience a net downward force. As a result, the crate will sink and accelerate downwards.
Therefore, the correct answer is the third option.
and you had to literally restate the exact same thing as her because?
the forces acting on the crate are gravity and buoyancy
what's the net result?
