Answer:
0.577
Explanation:
The initial weight is
mg= 
.......................1
and the final weight is
......................2
now to calculate 
now dividing equation 1 by equation 2 we get
= 1/3
=0.577
Answer:
Binding energy = 10.55 MeV
Explanation:
The mass defect is;
Δm = 13.005738u + 1.008665u - 14.003074u = 0.011329u
In mass defect, a mass of 1 u is equivalent to an energy of 931.5 MeV.
Thus, the binding energy of the neutron in MeV will be;
0.011329 x 931.5 = 10.55 MeV
Force becomes 1/4th
<u>Explanation</u>:
- Force between two positively charged particles is given by the equation
F = k×q1×q2/r² So, force is inversely proportional to square of r.
Here, k is a constant, q1 and q2 are the charges which are equal and r is the distance between them.
- So if the distance is doubled, r becomes 2r and r² becomes (2r)² = 4r²
- Force, F then becomes 1/4th of the initial force.
Those metals which conduct the electricity or heat partially, which may be good or bad conductors of heat and electricity is half -metals or semi metals.
The tiger's position at time <em>t</em> is given by
<em>x</em> (horizontal) = (4.5 m/s) <em>t</em>
<em>y</em> (vertical) = 7.5 m - 1/2 <em>gt</em> ²
Solve <em>y</em> = 0 for <em>t</em> to find the time it takes for the tiger to reach the ground :
0 = 7.5 m - 1/2 (9.8 m/s²) <em>t</em> ²
===> <em>t</em> = √(2 (7.5 m) / (9.8 m/s²)) ≈ 1.2 s
Evaluate <em>x</em> at this time :
<em>x</em> = (4.5 m/s) (1.2 s) ≈ 5.6 m
