Answer:
that's your 1st cousin which is your mom or dad's sibling's child sooo when you're that close and that related i would say that that would be the reason why.

<span>Near the equator, the patterns of convection currents are called
Hadley Cells.</span>
Hadley Cells refers to the low-latitude overturning movements that
have air increasing at the equator and air dropping at roughly latitude of 30
degree and these cells are also responsible for the trade winds in the Tropics
and control low-latitude patterns of weather.
Answer: a) 2.5 * 10^14, b) t = 1.2*10^-8 s, c) F = 2.2775 * 10^-15 N
Explanation: Since it starts from rest, initial velocity = 0, final velocity (v) = 3*10^6 m/s, distance covered (s) = 1.80cm = 1.80/100 = 0.018m
Since the force on the electron is constant, it acceleration will be constant too thus making newton's laws of motion valid.
Question a)
To get the acceleration, we use the formulae that
v² = u² + 2as
But u = 0
v² = 2as
(3*10^6)² = 2*a*(0.018)
9* 10^12 = 0.036*a
a = 9 * 10^12 / 0.036
a = 250 * 10^12
a = 2.5 * 10^14 m/s².
Question b)
To get the time, we use
v = u + at
But u = 0
v = at
3*10^6 = 2.5 * 10^14 * t
t = 3*10^6 / 2.5*10^14
t = 1.2*10^-8 s
Question c)
To get the force, we use the formulae below
F = ma
F = 9.11*10^-31 * 2.5 * 10^14
F = 22.775 * 10^-17
F = 2.2775 * 10^-15 N

Answer:
5000 kg.m/s
Explanation:
Before collision, momentum of 100 Kg is given by
p=mv where p is momentum, m is the mass of object and v is the velocity,
therefore, the momentum=100*50=5000 kg.m/s
The momentum of the 50 Kg is zero since it's at rest hence v=o
Total momentum before collision is therefore 5000+0=5000 kg.m/s
