PLEASE HELP ME !!!

Physics
1 answer:
Bogdan [553]3 years ago
4 0

Because the temperature causes it to go the physical change like if water is froze the temperate just caused it to go through another state of matter another example as if the ice got melted you would need high temperature to cause this change physically. Let me know if I help or if their is anything I can change for you to understand better

A star may form a black hole once it cannot ?
IceJOKER [234]

A star may form a black hole once is true. After the marked supernova explosion, the star shrinks because it sheds away the gaseous layers of the star. And especially if the star is large, it will form into a black hole.

An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45° relative to edge of the sidewalk. If it has
Marat540 [252]

Answer:14 s

Explanation:

Given

Velocity of ant is 0.1 m/s in a direction 45^{\circ}

if it has traveled 1 m perpendicular to the edge of the sidewalk

i.e. from diagram

\sin 45=\frac{1}{L}

L=\sqrt{2}

time=\frac{Distance}{speed}

t=\frac{\sqrt{2}}{0.1}

t=14.14 s

A hoop, a solid cylinder, a spherical shell, and a solid sphere are placed at rest at the top of an inclined plane. All the obje
iogann1982 [59]

Answer:

Solid sphere will reach first

Explanation:

When an object is released from the top of inclined plane

Then in that case we can use energy conservation to find the final speed at the bottom of the inclined plane

initial gravitational potential energy = final total kinetic energy

mgh = \frac{1}{2}mv^2 + \frac{1}{2}I\omega^2

now we have

I = mk^2

here k = radius of gyration of object

also for pure rolling we have

v = R\omega

so now we will have

mgh = \frac{1}{2}mv^2 + \frac{1}{2}(mk^2)(\frac{v^2}{R^2})

mgh = \frac{1}{2}mv^2(1 + \frac{k^2}{R^2})

v^2 = \frac{2gh}{1 + \frac{k^2}{R^2}}

so we will say that more the value of radius of gyration then less velocity of the object at the bottom

So it has less acceleration while moving on inclined plane for object which has more value of k

So it will take more time for the object to reach the bottom which will have more radius of gyration

Now we know that for hoop

mk^2 = mR^2

k = R

For spherical shell

mk^2 = \frac{2}{3}mR^2

k = \sqrt{\frac{2}{3}} R

For solid sphere

mk^2 = \frac{2}{5}mR^2

k = \sqrt{\frac{2}{5}} R

So maximum value of radius of gyration is for hoop and minimum value is for solid sphere

so solid sphere will reach the bottom at first
