The first requirement is to
look at all the vital information’s given in the question. Based on those
information’s the answer to the question can be easily reached.
Distance that needs to be covered for the race = 38.4 kilometer
Time required to complete the race = 4.5 hours
Then
Average speed = Distance/Time
= 38.4/4.5 km/hour
= 8.53 km/hr
So the average speed would be 8.53 Km/hr.
I hope the answer to the
question is what you were looking for and the procedure is clear to you.
Answer:
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
Explanation:
Given :
Frequencies of the sinusoids,
, and
Sampling rate
The positive frequencies at the output of the sampling system are :
When n = 0,
when n = 1,
When n = 2,
Therefore, the first six positive frequencies present in the replicated spectrum are :
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
Earths atmosphere, Temperature, Plant life and Oxygen I guess
Answer:
218.5 N
Explanation:
In order for the sled to be in equilibrium along the vertical direction, the forces acting along this direction must be balanced. So the equilibrium equation is:
where
N is the normal force
F = 50 N is the force that pulls the sled
is the angle between the force and the horizontal, so
is the component of F acting along the vertical direction
(mg) is the weight of the sled, with
m = 25 kg being the mass of the sled
g = 9.8 m/s^2 is the acceleration due to gravity
Solving the formula for N, we find
