Answer:
0.25 cm³.
Explanation:
We shall apply Boyle's law to find the solution . According to it
PV = constant where P is pressure and V is volume of the gas.
P₁ V₁ = P₂V₂
1 x .5 = 2 x V₂
V₂ = 0.25 cm³.

Pivoting is moving around while _______________ Group of answer choices One foot is ot the ground at all times both feet are on the ground and stationary Jumping around while dribbling shooting the ball
Answer:
sounds like "Jumping around while dribbling shooting the ball"
Answer: One foot is it the ground at all times
Explanation:
Pivoting is keeping either your right or left foot on the ground while your opposite foot is moving, you may move in a circle. But if you take a step with the foot that is not supposed to move, you are traveling and it will be a foul. Pivoting is meant to get a pass off or a shot.

How are infrared waves and radio waves similar? How might you use each?
Answer:
They are both eletro-magnetic waves, they are both outside of the range humans can see with our eyes. Infrared waves can can carry enough energy to give heat to objects. There is a lot of Infrared light that is put out by a fire and we feel that as the heat. Radio waves can be used to carry other signals like when we listen to the radio.
Explanation:
Answer:
Both infrared and radio waves are longer than visible light and are not considered harmful to humans.Infrared light is how remote controls communicate with electronics like televisions and stereos, while radio waves are how cell phone signals are transmitted.

Ball A is projected vertically upwards at a velocity of 16m.s-¹ fron the ground. ignore the effects of air friction. use the ground as zero reference. a) calculate the time taken by ball A to return to the ground. b) draw a velocity time graph for ball A
Answer: 3.26 s
Explanation:
Given
The ball is projected upward with a velocity [tex]u=16\ m/s[/tex]
Using the equation of motion
[tex]s=ut+\frac{1}{2}at^2[/tex]
Here, displacement is zero as the ball returns to its initial position
[tex]\Rightarrow 0=16\times t-0.5\times g\times t^2\\\Rightarrow t(16-0.5\times 9.8\times t)=0\\\text{i.e.}\ t=\dfrac{16}{4.9}=3.26\ s[/tex]
the velocity of the ball at any instant is given by
[tex]v=u+at\\v=16-9.8t[/tex]

A pendulum has a mass of 0.060 kg swinging at a small angle from a light string, with a period of 1.4 s. What is the length of the pendulum?
Answer:
0.5 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 0.060 kg
Period (T) = 1.4 s
Lenght (L) =?
NOTE:
1. Acceleration due to gravity (g) = 10 m/s²
2. Pi (π) = 3.14
The length of the pendulum can be obtained as follow:
T = 2π√(L/g)
1.4 = 2 × 3.14 × √(L/10)
1.4 = 6.28 × √(L/10)
Divide both side by 6.28
1.4 / 6.28 = √(L/10)
Take the square of both side
(1.4 / 6.28)² = L/10
Cross multiply
L = 10 × (1.4 / 6.28)²
L = 0.5 m
Therefore, the length of the pendulum is 0.5 m
Answer:0.49

if tungsten (w) has 90 neutrons then its mass number is?
Answer:
164
Explanation:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Neutrons: 90
Mass number?
Atomic number of Tungsten: 74
90 + 74 = 164

heat engine operating between 100 °C and 700 °C has an efficiency equal to 40% of the maximum theoretical efficiency. How much energy does this engine extract from the hot reservoir in order to do 5000 J of mechanical work?
Answer:
Explanation:
Theoretical efficiency = T₁ - T₂ / T₁ where T₁ and T₂ is absolute temperature of hot and cold end of the heat engine.
= 600 / (273 + 700 )
= 600 / 973
= .6166
operating efficiency = 40% of .6166
= .4 x .6166
= .2466 = 24.66 %
efficiency = work output / heat input
= 5000 / heat input = .2466
heat input = 5000 / .2466
= 20275.75 J .
HEAT EXTRACED = 20275.75 J.

In many areas electricity is produced by huge generators close to dames. What function does a large volume of moving water have in generating electricity?
Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
