Explanation:
If box weight 25N on ground
MA=F
M(10)=25
M=2.5Kg
this is due to the existence of other forces called the strong nuclear forces that overcomes the repulsion forces between the protons and keeps the nucleons holding to each other also there is a type of energy that is called the nuclear binding energy and this energy also works on binding the components of the nucleus together
Answer: C. Steel
Explanation: When a sound wave travels through a solid body consisting
of an elastic material, the velocity of the wave is relatively
high. For instance, the velocity of a sound wave traveling
through steel (which is almost perfectly elastic) is about
5,060 meters per second. On the other hand, the velocity
of a sound wave traveling through an inelastic solid is
relatively low. So, for example, the velocity of a sound wave
traveling through lead (which is inelastic) is approximately
1,402 meters per second.

#1
Work done is given by
here we know that
F = 157 N
d = 14.5
now from the above formula
#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg
#3
By momentum conservation we know that
#4
by momentum conservation we know that
let direction of velocity of Jay Z car motion is positive direction
now we will say
Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say
here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
