A sphere of radius r =34.5 cm and mass m = 1.80 kg starts from rest and rolls without slipping down a 30.0∘ incline that is 10.0 m long.
A.) calculate its translational speed when it reaches the bottom.
B.) Calculate its rotational speed when it reaches the bottom.
C.) what is the ratio of translational to rotational kinetic energy at the bottom?
Answer:
Explanation:
It depends on the construction of the sphere.
Let's ASSUME it is uniform construction with a moment of inertia (2/5)mR²
The Change in potential energy will equal the change in kinetic energy
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/5)mR²)(v/R)²
2gh = v² + 2/5v²
2gh = 7/5v²
v = √((10/7)gh)
v = √((10/7)(9.81)(10.0sin30.0))
A) v = 8.37 m/s
B) ω = 8.37/0.345 = 24.3 radians/s
C) ½mv² / ½Iω² = mv²/Iω² = mv²/((2/5)mR²)(v/R)² = 5/2

In terms of energy transfer, how is a rise in
temperature different from a drop in
temperature?
Answer:
Let's look deeper into it.
Explanation:
Heat energy corresponds to the transfer of thermal energy between two given objects. Temperature itself gives off the measurement of how much thermal energy any given object has.
The higher the measurement, the more heat there is. The lower the measurement, the less heat there is.

A particle at the origin is experiencing three forces. The first one has a magnitude of 57 lb and is directed towards (2,-4,5), while the second one has a magnitude of 32 lb and is directed towards (-1,-2,-8). If the net force is 41 lb in the direction of (-5,-1,4), what is the x-component of the third force acting on the particle (in lb)?
The x-component of the third force acting on the particle is 41.2 lb.
The given parameters;
(2, -4, 5) = 57 lb(-1, -2, -8) = 32 lb(-5, -1, 4) = 41 lbThe vector components of the forces is calculated as;
[tex]F_1 = 57, (2,-4, 5) = 57\times \frac{2i -4j+ 5k}{\sqrt{2^2 + 4^2 + 5^2} } = 8.5(2i -4j+ 5k)\\\\F_1 = (17 i -34j + 42.5k)lb\\\\\\ F_2 = 32, (-1, -2, -8) = 32\times \frac{-i -2j-8k}{\sqrt{1^2 + 2^2 + 8^2} } = 8.3(-i-2j-8k)\\\\ F_2 = (-8.3i - 16.6j - 66.4k)lb\\\\\\ F_{net}= 41, (-5, -1, 4) = 41\times \frac{-5i -j+ 4k}{\sqrt{5^2 + 1^2 + 4^2} } = 6.5(-5i-j+ 4k)\\\\ F_{net} = (-32.5i -6.5j+ 24k)lb[/tex]
The x-component of the third force is calculated from the resultant of the forces;
[tex]F_1+F_2 + F_3 = F_{net}\\\\F_3 = F_{net} - (F_1 + F_2)\\\\F_3 = (-32.5i -6.5j + 24k) - (17i -34j + 42.5k) - (-8.3i -16.6j -66.4k)\\\\F_3 = (-32.5 -17 + 8.3)i +(-6.5 + 34+ 16.6)j + (24 -42.5+66.4)k\\\\F_3=(-41.2 i) +(44.1)j + (47.9)k\\\\F_3 = (-41.2i + 44.1 j + 47.9k)lb[/tex]
Thus, the x-component of the third force acting on the particle is 41.2 lb.

The muscular system consists of exclusively this kind of tissue.
Answer:B
Explanation:
Each muscle or organ is composed of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Thus, the muscular system consists of all types of tissue.
What is the muscular system?The Muscle fibers are specialized cells that make up the muscular system. Its ability to contract is its main characteristic. Muscles that are attached to bones, internal organs, or blood arteries are what move things. Muscle contraction is the primary cause of almost all bodily movement. A skeletal muscle on its whole is a part of the muscular system.
Muscle cells, also known as muscle fibers or monocytes (mostly in skeletal and cardiac muscle), make up the majority of the organs that make up muscles (mainly in smooth muscle).
By contracting and pushing food to the small intestine through a process known as peristalsis, the muscles surrounding the stomach aid in the flow of food through the digestive system.

1. Your big brother, despite warning, drops a penny off the observation
deck of the Empire State Building in New York City. The observation
deck is 381 m above the ground. What is the terminal velocity of the
penny? How far has the penny fallen after 3 seconds?
Answer:
The marble will take 8.813 seconds to hit the ground.
Explanation:
The marble will fall according to this motion equation: y(final) = y(initial) + v(initial)×t + 1/2×a×t×t
y(final)=0 m, the marble's final position in relation to the ground
y(initial)=381 m, the marble's initial position in relation to the ground
v(initial)=0 m/s (meters per second), the marble's initial velocity (speed with direction) when fall first begins
t=? seconds, this is the amount of time that passes while falling, the variable in this problem
a=-9.81 m/s/s, the rate at which the velocity of the marble changes, acceleration. On Earth, neglecting friction, acceleration is a constant at negative 9.81 meters per second squared
Plug the values into the equation: 0= 381 + 0t + 1/2(-9.81)(t)(t)
Subtract 381 from both sides and disregard 0t because it has no value and no longer matters: -381= 1/2(-9.81)(t)(t)
Multiply out the equation: -381= -4.905(t)(t)
Divide both sides by -4.905 to isolate the variable: 77.676=(t)(t)
Find the square root of both sides: t=8.813 seconds
Which statement is TRUE regarding the sleeping brain?
A. Some brain neurons remain active during sleep, while others do not.
B. The sleeping brain is idle.
C. Sleep is a global, brain-wide state.
D. All brain areas are shut down during sleep.
Many biological processes happen during sleep: The brain stores new information and gets rid of toxic waste. Nerve cells communicate and reorganize, which supports healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins.
The true statement regarding the sleeping brain is: sleep is a global, brain-wide state, which is in option c as sleep is not a state of idleness or a shutdown of all brain areas.
Sleep is a complex and dynamic process that involves various regions and functions of the brain. While some brain neurons may decrease their activity during certain stages of sleep, other neurons remain active and play crucial roles in regulating sleep processes. Sleep is considered a global state because it involves widespread changes in brain activity and connectivity. Different brain regions exhibit synchronized patterns of activity during specific sleep stages, and these patterns contribute to functions such as memory consolidation, restoration, and emotional processing.

In the Freebody diagram the magnitude of the normal force is 40 N, the friction force is 25N, the net force is 80N. what is the magnitude of the applied force?
Answer:
Explanation:
Without the FBD or a good description of the set up, I'd have to say we cannot tell.
If the set up is of the simplest form with a mass on a horizontal surface being acted on by a horizontal force, then that force must be 80 + 25 = 105 N.
As force is a vector, there are an infinite number of other possibilities for force magnitude depending on which direction the force is acting. The mass is also an unknown variable that would affect the applied force magnitude if the direction is not horizontal.

Basketball dropping
Bike going off a jump

Answer:
F = 1 N
Explanation:
F = Gm₁m₂/r² + kq₁q₂/r²
F = (Gm₁m₂ + kq₁q₂) / r²
F = [6.674(10⁻¹¹)(0.50)(0.25) + 8.988(10⁹(5(10⁻⁶))(-2(10⁻⁶))] / 0.30²
F = 0.9986666667593611111...
