Given Information:
Mass = m = 3 kg
Speed = v = 6 m/s
Radius = r = 2 m
Required Information:
Magnitude of the acceleration = a = ?
Answer:
Magnitude of the acceleration = 18 m/s²
Explanation:
The acceleration of the block traveling along a circular path with some velocity is given by
a = v²/r
a = 6²/2
a = 36/2
a = 18 m/s²
Therefore, the magnitude of the acceleration of the block is most nearly equal to 18 m/s².
Bonus:
The corresponding force acting on the block can be found using
F = ma (a = v²/r)
F = mv²/r
<span>Cartilage is the hard but flexible structure found in pieces of your nose and ears. It is similar to bone, but allows for flexibility and movement. When looking at skeletons, you'll notice that they don't have a nose or ears, because cartilage deteriorates much faster than bone. Cartilage is also found in elsewhere in the animal kingdom--the skeletal structure of a shark is made primarily from cartilage!</span>
I think it’s false .
Let me know if it’s incorrect .
Answer:300 joules
Explanation:The formula for specific heat is:
E
=
m
c
θ
, where:
E
is the energy needed in joules,
m
is the mass in kilograms,
c
is the specific heat,
θ
is the change in temperature, Celsius of Kelvin doesn't matter.
Here,
m

They're extremely small, occupying a very small volume, to the point where something like wind resistance that we think about with accelerating large objects like planes becomes completely irrelevant. A rogue electron can fly straight through most solid objects through the "empty space" between atoms. Their mass is also extremely small, 9.1*10⁻³¹ kg, making them relatively easy to accelerate to near light speeds (in comparison to other forms of matter) as it takes very little energy to set them into motion. Particle accelerators accelerate electrons to 99% of the speed of light in the real world every day.
