On the off chance that a 2.45 GHz microwave flag is by one means or another radiating from your microwave oven, that is exceptionally perilous and you ought to have it settled or supplanted promptly. A 1000 Watt microwave oven radiating energy into the nearby environment can, contingent upon conditions, make you lose awareness in around 12 to 15 minutes of presentation at a separation of around 10 feet.
Answer:81.24 m/s
Explanation:
Given
Horizontal displacement()=500
Angle of projection
Let u be the launching velocity
and horizontal range is given by
I think it is first but don’t take my word for it
Answer:
The required amplitud is 0.11cm
Explanation:
To solve this problem it is necessary to apply the concepts related to simple harmonic motion, where displacement is given by
Where,
A = Amplitude
f = Frequency
t = time
If we derivate the expression we can obtain the Acceleration, there
x would be A for the minimum amplite of vibration, then
Replacing with out values,
Therefore the required amplitud is 0.1146cm
