The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
<h3>Why does water change in volume?</h3>
Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.
One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.
As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.

The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
Hello!
We can use the following equation for calculating power dissipated by a resistor:
P = Power (? W)
i = Current through resistor (2.0 A)
R = Resistance of resistor (50Ω)
Plug in the known values and solve.
Answer:
185.95 μsec
Explanation:
Given that:
Sine wave = 
Sinusodial signal 
= 50 kHz = 
Rise time is said to be defined as the time needed for a pulse to rise from 10% - 90% of maximum rate.
∴
= 10% = 0.1 Am
=90% = 0.9 Am
Using sine wave for ; we have:
= 0.1 Am
= 0.1
= 5.7392
Using sine wave for ; we have:
= 0.9 Am
= 
= 64.158
= 
= 
Change in rise time 
= -
= 
= 
= 
since; = 50 kHz =
= 
= 1.85952 × 10⁻⁴
= 185.952 × 10⁻⁶ sec
= 185.95 μ sec
∴ The rise in time in (μ sec) for the sinosodial signal at 50 kHz = 185.95 μ sec
Answer:
Gravitone
Explanation:
In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravity. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity.
