Answer:
The correct option is B
Explanation:
The number of alphabet is n= 4 (a , b , c , d )
Generally the total number of string of length 10 over the 4 alphabets is
Gnerally the number of string of length 10 that does not include b is
Generally the number of strings of length 10 over the 4 alphabets that have at least one alphabet b somewhere in the string is
=> 
It’s 1 that would be the lowest point potential energy
Answer:
B. Decrease the plane’s speed and height
Explanation:
Decrease in speed of plane:
When the speed of the plane is decreased then initial velocity of the package will be lesser. As a result, final velocity will also be lesser because in this case final velocity depends upon the initial velocity.
Decrease in height:
According to law of conservation of energy:
Loss in potential energy = Gain in Kinetic energy
mgh = ½ mV^2
It means with the decrease in height less potential energy will be converted to kinetic energy. As package has constant mass so it will gain less velocity.
Answer:
hope that helps
Explanation:
This implies that the discovery of life on Mars does not automatically mean the ... Hence, we hope that Mars may have been the site of an independent origin of life. ... The general view of the results of the Viking biology experiment is that there is ... subsurface may hold liquid water aquifers that support chemosynthetic life.
Terminal speed=136.7 m/s
the formula for the terminal speed is given by :
V= 
m= mass=75 kg
a= area=0.2 x 0.4=0.08 m²
ρ= density of air=1.23 kg/m³
C= drag constant =0.8
so V= 
v= 136.7 m/s
