Answer:
94 kg or 921.6 N
Explanation:
The velocity function is . The acceleration function, a(t), is the time derivative of the velocity function.
At ,
Because the elevator is going upwards, the net acceleration, where g us acceleration of gravity.
The resultant weight is
Since the bathroom scale is graduated in kg, it's reading is
Answer:
2.837% less than actual value.
Explanation:
Based on given information let's calculate our value.
S = Vxt = 331m/s x 5s = 1655m, that is the total distance that sound would travel in 5 seconds.
1mile = 1609.34meters.
percentage error is.
negative indicates less than actual value.
Answer:
The value is
Explanation:
From the question we are told that
The frequency of each sound is
The speed of the sounds is
The distance of the first source from the point considered is
The distance of the second source from the point considered is
Generally the phase angle made by the first sound wave at the considered point is mathematically represented as
Generally the phase angle made by the first sound wave at the considered point is mathematically represented as
Here b is the distance o f the first wave from the considered point
Gnerally the phase diffencence is mathematically represented as
=>
Gnerally the wavelength is mathematically represented as
