Most likely the atoms of that elements are compress. :)
Answer:
1.8 m/s
Explanation:
momentum = mass × velocity
initial momentum = m1v1+m2v2
= 3×3 +2×0 = 9+0= 9 kg m/s
let combined velocity be V
HENCE
final momentum = total mass × velocity
= (3+2) × V = 5V
According to law of conservation of momentum
final momentum = initial momentum
5V = 9
V =9/5
V = 1.8 m/s
Answer:
0.037 N/m
Explanation:
The web acts as a spring, so it obeys Hook's law:
(1)
where
F is the force exerted on the web
k is the spring constant
x is the stretching/compression of the web
In this problem, we have:
- The mass of the fly is 
- The force exerted on the web is the weight of the fly, so:
- The stretching of the web is
So if we solve eq.(1) for k, we find the spring constant:
Answer:
Three uses that ultraviolet radiation is used for is for cleaning tools like for doctors or dentists, suntanning, and photo therapy. This can be okay and worth the risk if used carefully and with protection. Otherwise, it can cause cancer or blindness
Explanation:
Answer:Temperature is a measure of average kinetic energy of particles in an object.
Explanation:
The hotter the substance, higher is the average kinetic energy of its constituent particles. When we heat a substance, the particles that constitute the substance gain some energy and begin to move faster.
