Answer:
450N
Explanation:
Impulse = mv ---> 180kgm/s = (0.5kg)v
v = 360 m/s
Acceleration = v/t ---> a = (360 m/s)/(0.4s) = 900 m/s^2
Force = ma ---> F = (0.5kg)(900 m/s^2) = 450N

Explanation:
Below is an attachment containing the solution.
T is in seconds (s)
<span>2pi is dimensionless </span>
<span>L is in meters (m) </span>
<span>g is in meters per second squared (m/s^2) </span>
<span>so you can write the equation for the period of the simple pendulum in its units... </span>
<span>s=sqrt(m/(m/s^2)) </span>
<span>simplify</span>
<span>s=sqrt(m*s^2*1/m) cancelling the m's </span>
<span>s=sqrt(s^2) </span>
<span>s=s </span>
<span>therefore the dimensions on the left side of the equation are equal to the dimensions on the right side of the equation.</span>
Answer: A haploid cell formed in the female uterus
Answer:
Explanation:
From the question we are told that
The electric filed is 
Generally according to Gauss law
=> 
Given that the electric field is pointing downward , the equation become
Here 
is the excess charge on the surface of the earth
is the surface area of the of the earth which is mathematically represented as
Where r is the radius of the earth which has a value 
substituting values
So
Here 
s the permitivity of free space with value
substituting values
