What part of the atom determines physical properties?

Physics
1 answer:
cluponka [151]3 years ago
6 0

Explanation:

Physical properties are the properties which can be observed without any change in chemical composition of a substance. For example, color, odor, mass, density etc are all physical properties.

An atom contains protons, neutrons and  electrons. The nucleus of atom contains protons and neutrons. The mass of an electron is negligible as compared to protons.

Therefore, mass of an atom is due to the number of protons.

Hence, we can conclude that protons of the atom determines physical properties.

in a circuit with two resistors in parallel, which of the following pair applies? a. V and I both increase across both resistors
makvit [3.9K]

The wording of the choices is really unclear.  With two resistors in parallel,
here's the situation:

-- The voltage across each resistor is the same as the voltage across
the other one.  If the parallel combination is connected to the battery,
then the voltage across each resistor is the full battery voltage.

-- The current through each resistor is (V) / (the resistance of that resistor).
That's the same current as would flow through that resistor if the other one
were not there.

-- As long as the battery or other power supply holds out, neither of these
quantities changes.

Can you match this situation to one of the choices listed ?
It looks to me as if choice 'C' is the one that's most likely
trying to say this.

A baseball is hit nearly straight up into the air with a speed of 22 m/s. (a) how high does it go? (b) how long is it in the air
Mariulka [41]
Refer to the diagram shown below.

When the ball attains maximum height, it will have zero vertical velocity.
The maximum height, h. obeys the equation
0 = (22 m/s)² - 2*(9.8 m/s²)*(h m)
h = 22²/(2*9.8) = 24.694 m

Answer: The maximum height attained is 24.7 m (nearest tenth)

Part b.
The vertical height traveled by the ball obeys the equation
h = (22 m/s)t - (1/2)*(9.8 m/s²)*(t s)²
where
h = vertical height, m
g = 9.8 m/s², acceleration due to gravity
t = time, s

To find how long the ball stays in the air, set h = 0 to obtain
4.9t² - 22t = 0
t(4.9t - 22) = 0
t = 0, or t = 22/4.9 = 4.49 s
t = 0 corresponds to the launch, and t = 4.49 s corresponds to when the ball retuns to the ground.

Answer: The ball stays in the air for 4.5 s (nearest tenth)
