In statistics there are different types of distributions, like rectangular, or Poisson, A normal distribution is bellshaped
Answer:
15.13 m/s
Explanation:
The wave speed of the stretched rope can be calculated using the following formula
where 
is the tension on the rope and 
is the density of the rope per unit length
Answer: T = G - H/100
T= 12 - 12000/100 = 12 - 120 = - 105 degrees
Explanation:
T = G - H/100
T is temperature in centigrade degrees.
G is the temperature in centigrade degrees at ground level.
H is the height above ground level measured in meters.
assuming the temperature at ground level is 15 degrees centigrade, then G = 15.
the formula then becomes:
T = 15- H/100.
at ground level, H = 0 and the formula becomes 15 - 0/100 = 15 degrees centigrade.
at 100 meters, H = 100 and the formula becomes 15 - 100/100 = 15 - 1 = 14 degrees centigrade.
at 12 km above ground level, H = 12000 and the formula becomes 15 - 12000/ 100 = 15 - 120 = -105 degrees centigrade.
Answer: v= 160ft/s
a=32ft/s^2 constant
Explanation:
s(t)=400-16t^2 derivative of position is velocity v(t) and derivative of velocity is acceleration a(t) so let s(t)=0 to find the time of flight to reach the ground and take the two derivatives and use the time found and solve. Also acceleration is a constant as it’s gravity.
0=400-16t^2
400=16t^2
25=t^2
t=5s
ds/dt=v(t)=0-32t
dv/dt=a(t)=-32 constant(gravity)
v(t)=-32(5s)= -160ft/s negative sign is only showing direction
Answer:
spiral
Explanation:
A galaxy may be defined as the huge collection of celestial bodies like the stars, planets, dark matters, dust and gases and the solar systems. It is derived from the Greek work, 'Galaxias' , which means "milky". There are many types of galaxies. They are : Spiral galaxy, Elliptical galaxy, Irregular galaxy and Barred spiral galaxy.
A spiral galaxy is one which contains a sphere shaped bulge which consists of old stars and it is devoid of dust and gas. Its circular shape composes a disk. It is of circular shape having most of the objects concentrated in its center.
