The term which describes different atomic masses of similar atom because of varying numbers of neutrons are Isotopes.

<u>Explanation: </u>

The isotopes are the chemical element which has different atomic masses due to the fact that number of neutrons are not same but it has same number of proton.

When the number of neutron increases in a nucleus, with the same electronic configuration and same number of proton, element is said to have isotopes. There are may be variants of isotopes of an element. For example, hydrogen has 3 isotopes.

A golfer strikes her tee shot with the following velocities, vx = 106 m/s &amp; vy = 66.2 m/s. a. What is the velocity of flight
lara [203]

Answer:

a) V ≈ 125 m/s;  b) Δt = 13.24 s;  c) ΔS ≈ 1450 m

Explanation:

a) We have just to calculate the vector resultant.

V² = 106² + 66.2²

V² = 15618.44

V ≈ 125 m/s

b) The time of flight is equal to the time to reach the maximum height summed to the time to reach the land.

In vertical:

V = V₀ + a * t

V = 66.2 - g * t

0 = 66.2 - 9.8 * t

t ≈ 6.76 s

So: Δt = 13.24 s

c) In horizontal:

V = ΔS / Δt

106 = ΔS / 13.52  ⇒  ΔS = 106 * 13.52

ΔS = 106 * 13.52

ΔS = 1433,12

ΔS ≈ 1450 m

A 1.8-kg object moves in the x direction according to the following function:
DanielleElmas [232]
Well, if the position is   <u> x(t)  =  2t² + 3t - 5</u>

then the speed is          x ' (t)  =  4t + 3    (first derivative of  'x'  wrt  't')

and the acceleration is     x ' ' (t)  =  4      (second derivative of  'x'  wrt  't')

Apparently, then, the acceleration is constant, and is not a function of time.

After 2.7 seconds or 2.7 years, the acceleration is  4 .

Force = (mass) x (acceleration)

Force =  (1.8)    x      (4)

<em>Force =            7.2 newtons </em>

One of two nonconducting spherical shells of radius a carries a charge Q uniformly distributed over its surface, the other carri
lisabon 2012 [21]

Answer:

Explanation:

A ) The spheres are non conducting , charge will not move on the surface so neutralization of charge by + ve and - ve charge is not possible. Charges will remain intact on them . The electric field inside them will be zero . Electric field outside shell  will not be spherically symmetrical . Lines of force will emanate from the surface of positively charged shell  outwardly oriented  and end at negatively charged shell .

B )

distance between the centres of spherical shell

= 2 a

potential energy of charges

= k q₁ x q₂ / R

= k x - Q x Q / ( 2a )

= - k Q²/ 2a

So work needed to separate them to infinity will be equal to

= k Q²/ 2a
