Moment of force = F x d . Here d is the distance from the fixed axis, Moment of force is expressed in newton meter (Nm). Moment of force formula can be applied to calculate the moment of force for balanced as well as unbalanced forces.
What does a higher value of k and a lower value of k tell about the strength of the spring? (Hint: In which case is it soft or stiff?)
Answer:
' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons
Explanation:

A bullet is fired straight up from a gun with
a muzzle velocity of 166 m/s.
Neglecting air resistance, what will be its
displacement after 8.6 s? The acceleration of
gravity is 9.8 m/s
Answer in units of m.
Explanation:
u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s
by the formula, S=ut+½at².
S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation
S = 1427.6+362.404
S=1790.004m

can you predict a dark room is empty or not with the help of sound? how?
please help me ।
50 points
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.
Explanation:
With this information, you'd be able to come up with your answer,

what supports a white dwarf against the crush of gravity?
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.

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