Answer:
135 m
Explanation:
Given:
vi = 12 m/s
vf = 18 m/s
t = 9s
Find: x
x = ½ (vf + vi) t
x = ½ (18 m/s + 12 m/s) (9 s)
x = 135 m
Explanation:
It is given that,
Mass of platinum bar, m = 750 g
Length of the bar, l = 5 cm
Breadth of the bar, b = 4 cm
Width of the bar, h = 1.5 cm
Volume of the bar, 
We need to find the density of the platinum bar. The density of any substance is given by :
So, the density of the platinum bar 
. Hence, this is the required solution.
<span>120 revolutions per min is (20RPM)
120revolutions is 240 Pi radians (because 1 revolution is 2Pi rad)
angular velocity
w= 240Pixf, f is the frequency and f= 1/T, T =1mn=60s=period, so f=1/60=0.01Hz
so w = 240*Pi*0.01=12.56 rad /s
linear velocity can be found with
V =Rx w,
V=12.56 R the value depends on what value is the radius of both wheels

Answer:
No ! its False
Explanation:
We all know , we dont have lunar eclipse in every 27 days . They do not happen every month because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
I am not sure if this is the answer you are looking for but a earthquake occurs when the plates shift.
Hope this helped.
