In the game of shuffleboard, you push plastic disks forward and then release them so that they slide across a level playing surface. Once you release a disk, you are no longer pushing and it gradually skids to a stop. Its final position determines your score. As each disk skids to a stop, what becomes of the kinetic energy it had when you released it
Answer:
I believe it would then become potential energy.
Explanation:
If an object falls from rest and lands 3.2 seconds later, how many
meters did it fall
Answer:
50.2 meters
Explanation:
When an object falls, it goes a distance d in time t according to the formula:
[tex]d=\frac{1}{2}*g*t^{2}[/tex]
d is the distance in meter, g is the acceleration due to gravity with the value of 9.8[tex]m/s^{2}[/tex] , t is the time in seconds
Therefore, [tex]d = \frac{1}{2}*9.8*(3.2)^{2}[/tex]
d= 50.176 ≈ 50.2m

A 4.0 kg dog runs from one end of a 21 kg canoe to the other, a distance of 4.9 m. Assuming negligible water resistance, how far does the canoe move in metres?
The distance traveled by the canoe in the water is 0.93 m.
The given parameters;
mass of the dog, m = 4.0 kgmass of the canoe, = 21 kgdistance traveled by the dog, d = 4.9 mApply the principle of conservation of linear momentum to determine the distance traveled by the canoe;
[tex]m_1v_1 = m_2 v_2\\\\m_1(\frac{d_1}{t} ) = m_2(\frac{d_2}{t} )\\\\4(4.9) = 21(d_2)\\\\d_2 = \frac{4(4.9)}{21} \\\\d_2 = 0.93 \ m[/tex]

how much energy is needed to raise the temperature of 2kg of copper from 0°c to 10°c. the specific heat capacity of copper is 380j/kg°c
Explanation:
H= mass× specific heat capacity×change in temperature
=2×380×(10-0)
=2×380×10
=7600Joules
According to the specific heat capacity, 7600 joules of energy is required to raise temperature of 2 kg copper from 0-10 degree Celsius.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
In the given problem,energy is calculated as, Q=2×380×(10-0)=7600 J.
Thus, 7600 joules of energy is required to raise the temperature of 2 kg of copper from 0°C to 10°C.

Answer:
1.A
2.D
3.B
4.A
5.A
Explanation:
Every physical activity requires a specific amount of oxygen for the human organs (heart, lungs, and muscle). Athletes must breathe efficiently to perform at their best, since a high oxygen level reduces fatigue and dizziness and promotes peak performance. Thus option 1. A, 2. D, 3. B, 4. A, 5. A is correct.
What oxygen levels make an in athletic performance?The range of 95-99% represents normal, healthy oxygen saturation levels. And can be simply measured with a fingertip pulse oximeter, a cheap, basic equipment. Your blood oxygen saturation is most likely within the typical range for active, healthy athletes (like you!).
Numerous websites that promote the purported advantages of breathed oxygen can be found by searching for “supplemental oxygen and athletes.” Almost all of them receive funding from businesses that sell oxygen.
Therefore, Because it doesn't function, more oxygen is not regarded as a performance-enhancing substance.
