of elements in the same group, those at the bottom of the periodic table have low ionization energies because C. their atomic radius is large
Answer:
Explanation:
force constant of spring k = force / extension
= 35.6 / 0.5
k = 71.2 N / m
angular frequency ω of oscillation by spring mass system
where m is mass of the body attached with spring
Putting the values
ω = 3.77 radian / s
The oscillation of the mass will be like SHM having amplitude of 0.5 m and angular frequency of 3.77 radian /s . Initial phase will be π / 2
so the equation for displacement from equilibrium position that is middle point can be given as follows
x = .5 sin ( ω t + π / 2 )
= 0.5 cos ω t
= 0.5 cos 3.77 t .
x = 0.5 cos 3.77 t .
It is a vector quantity defined as the product of force acting on a body and the time interval during which the force is exerted...
Hope this helps!
Answer:
Explanation:
Given
zero vertical displacement
suppose \theta is the inclination angle and u is the initial velocity
considering horizontal motion
range is given by
where t is the time of flight
Now consider vertical motion
a=acceleration
for zero displacement y=0
substitute the value of t in Range
for maximum vale of must be equal to 1
i.e.
