What is the total kinetic energy of a 0. 15 kg hockey puck sliding at 0. 5 m/s and rotating about its center at 8. 4 rad/s? the diameter of the hockey puck is 0. 076 m.
The mass of the puck is
m = 0.15 kg.
The diameter of the puck is 0.076 m, therefore its radius is
r = 0.076/2 = 0.038 m
The sliding speed is
v = 0.5 m/s
The angular velocity is
ω = 8.4 rad/s
The rotational moment of inertia of the puck is
I = (mr²)/2
= 0.5*(0.15 kg)*(0.038 m)²
= 1.083 x 10⁻⁴ kg-m²
The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.
The translational KE is
KE₁ = (1/2)*m*v²
= 0.5*(0.15 kg)*(0.5 m/s)²
= 0.0187 j
The rotational KE is
KE₂ = (1/2)*I*ω²
= 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²
= 0.0038 J
The total KE is
KE = 0.0187 + 0.0038 = 0.0226 J
Answer: 0.0226 J

A probe orbiting venus exerts a gravitational force of 2. 58 × 103 n on venus. Venus has a mass of 4. 87 × 1024 kg. The mass of the probe is 655 kilograms. The gravitational constant is 6. 67 × 10-11 n*m2/kg2. To three significant digits, the probe is × 106 m from the center of venus.
Answer:
[tex]\mathrm{9.08 \times 10^6 \:km}[/tex]
Explanation:
To solve for the distance between the probe and the center of Venus, use the formula:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
Plugin the values:
G =
[tex]6.67\times10^{-11} \mathrm{\frac{m3}{kg\: s2}}[/tex]
[tex]\mathrm{F} =2.58 \times 10^3\mathrm{N}[/tex]
[tex]\mathrm{m1 = 4.87 \times 10^{24}\:kg}[/tex]
[tex]\mathrm{m2 = 655\: kg}[/tex]
Hence:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
[tex]2.58 \times 10^{23} = 6.67 \times 10^{-11} (4.87 \times 10^{24})[/tex]
[tex]\frac{(655)}{r^2}[/tex]
[tex]\mathrm{r = 9.08 \times 10^6 \:km}[/tex]

What should you do when a garbage can is nearly full.
Answer:
You can also place a false bottom inside the trash can to stop overfilling. To do that, simply place an object like a cardboard box underneath and outside the bag so that when it appears full it will not be as heavy as a bag that reached all the way to the bottom.
Explanation:
(winks and runs off)
When the garbage can is full, it is transferred into bigger dustbins that are placed outside the houses.
What is garbage management?Domestic composting, recycling, reusing, and burning or burying of waste in their own yards are all examples of on-site household waste management. Off-site household waste management consists of delivering separated recyclables to drop-off locations, dumping at a landfill or in public trash cans, or making donations.
The environment is protected from the hazardous effects of the inorganic and biodegradable elements included in trash via waste management. Air pollution, soil erosion, and water poisoning can all result from improper waste management. If waste is collected and managed well, it can be recycled.
Therefore, when the trash container is full, it is moved into larger trash containers that are positioned outside the homes.

The measure of angle COA will be 160°. Option C is correct. Center angle theorem is the base of the given problem.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D shapes.
The measure of an angle formed by an arc of a circle with any point on the circumference of that circle is half the angle formed by that arc at the center of the circle.
The angle formed by arc AC at the center, will be twice as large. Therefore,
∠AOC = 2∠ABC
∠AOC = 2(80°)
∠AOC = 160°

A desert is very hot during the day and receives very little rain. Which plants will likely survive in this kind of environment?.
Explanation:
A cactus is a plant that would survive
A desert is very hot during the day and receives very little rain. The plants that will likely survive in this kind of environment are plants with waxy coatings. Thus the correct option is A.
What is the environment?The environment is referred to as the surroundings where all living and nonliving things are present. The environment contains different types which include the atmosphere, hydrosphere, lithosphere, and biosphere.
Desert is referred as dryland which constitutes more than one-fifth of the planet's landmass and can be found on every continent. These regions experience a "moisture imbalance," which indicates that they typically lose more moisture to drainage.
The gravity of the waxy substance on their leaves, floating plants, which have short branches, would sink underwater if not for the weight of the leaves. The plant is shielded from hazards outside by the waxy layer, which also holds moisture.
Therefore, option A is appropriate.

Answer:
Correct answer is C) $14.200.39
Explanation:
we know that
The simple interest formula is equal to
I = Prt
P = I / (rt)
where
I is the amount of money in interest
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
in this problem we have
t = 9 years
I = $5,896
P = ?
r = 0.0692
substitute in the formula above
P = 5,896/ (0.0692 ÷ 6) = $14,200.39
therefore
the answer is option C)
$14,200.39
