First change km/ s into m/s, then use the formula
Lambda = velocity/ frequency
<span>Days and nights are equal in length everywhere.(gradpoint)</span>
Answer:
10 km/hr/s
Explanation:
The acceleration of an object is given by

where
v is the final velocity
u is the initial velocity
t is the time
For the car in this problem:
u = 0

t = 6 s
Substituting in the equation,

If your current exam mean is 97.2. and you receive a 99 on the next exam, then this will have the effect of increasing the mean.
<h3>What is the mean?</h3>
In statistics, the mean is an average value used to calculate when taking different measurements, which can be fundamental to collecting statistically significant information.
In conclusion, if your current exam mean is 97.2. and you receive a 99 on the next exam, then this will have the effect of increasing the mean.

Answer:
0
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
d = Vertical height from the ground
F = Force = Weight = mg
Net work done would be

Hence, the work done on the person by the gravitational force is 0
