Answer:
a)5m b)5secs c) 10secs
Explanation:
a) maximum height H = u²/2g
Given u = 50m/s
g = 10m/s²
H = 10²/20
H= 5m
maximum height reached by the rocket is therefore 5m
.b)Time it takes the rocket to reach its maximum height is Tmax = U/g
Tmax = 50/10
Tmax = 5seconds
c) How long the rocket spent in the air is the time of flight T
T = 2U/g
T = 2×50/10
T = 100/10
T = 10seconds
Answer:
Explanation:
Speed of the car is given as
here we know that
now we know that human body can sustain maximum acceleration of 30 g without any fatal
so here in order to find the stopping distance with survival condition we can say
Answer:
Explanation:
The frequency of an electromagnetic wave is given by:
where
is the speed of light
is the wavelength of the wave
For the first wave,
so the corresponding frequency is
For the second wave,
so the corresponding frequency is
So the difference between the two frequencies is
Answer:
Technician A and B are correct
Explanation:
Technician A is correct because the system app is used to calculate the amount of fuel required to go with the airflow.
Technician B is correct because Maf is incorporated with a sensor for detecting the amount of airflow.
The objects density is greater than one
