What acceleration would you expect a 100 kg individual to experience from a 1000N force?

Answers

Answer: 10 m/2^2

F=ma

Explanation:

Force = 1000N

1 N is 1 (kg*m/s^2)

Mass = 100kg

F=ma

a = F/m

a = (1000kg*m/s^20/(100kg)

a = 10 m/s^2

what supports a white dwarf against the crush of gravity?

Answers

Answer:  In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.

Explanation:

Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.

What is Degeneracy pressure?

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.

The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

Answers

Answer:

Sound waves can reflect off surfaces. We hear sound reflections as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes.

Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.

A truck brakes from 15 m/s to 2 m/s in 15 seconds. What is its acceleration?

Answers

If we take v=u+at and our given values are:

v=final velocity 20m/s

u=initial velocity 15m/s

a=acceleration

t=time 5sec

we plug those into our equation:

20m/s=15m/s+a(5s)

now we just rearrange to solve for acceleration.

(5m/s)/(5s)=a

a=1m/s^2
