Place the object in an electronic balance and measure its mass.
Place a measured amount of water in the cylinder.
Place the object in the cylinder so that it’s fully submerged.
Measure the new level of the liquid and subtract the original level. This is equal to the volume of the object.
Density = mass / volume.
The mass (in kg) of water in the pool is 1.264
kg.
<h3>What is mass?</h3>
A numerical measurement of inertia, a basic characteristic of all matter, in physics. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has.
Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.
Given: A pool is 31.4 m long and 40.0 m wide. if the average depth of water is 3.30 ft
31.4
40.0 = 1256 
1 m = 39.37 in = 3.28 ft
3.30 ft = 1.01 m
Volume of pool = 1256
1.01 = 1264 
Since 1
water contains
the volume of the pool is
1.264 E3
E3 = 1.264E6 kg
(or 1.264
kg)
The mass (in kg) of water in the pool is 1.264
kg.

Answer:
A
A fox and hawk can be both a predator and prey
Answer:
B. 0.16 m
Explanation:
The vertical distance by which the player will miss the target is equal to the vertical distance covered by the dart during its motion.
Since the dart is thrown horizontally, the initial vertical velocity is zero:

While the horizontal velocity is

The horizontal distance covered is

Since the dart moves by uniform motion along the horizontal direction, the time it takes for covering this distance is

along the vertical direction, the motion is a uniformly accelerated motion with constant downward acceleration g=9.8 m/s^2, so the vertical distance covered is given by
