Answer:
yes
Explanation:
make sure you do not touch where there is power leakage or else you can get electrocuted
Answer:
Explanation:
wavespeed = wavelength * frequency
wavespeed / wavelength = frequency
343 / 17 = 20.17 Hz
343 / 0.017 = 201764 Hz
So range of frequencies we can hear is between 20Hz and 20,000 Hz ( or 20.17 to 201764 if you dont round up/down)
The answer is b. According to the law of conservation of energy, energy can never be created nor destroyed, only transferred from one form to another.
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s

#SPJ1
when two vectors are inclined at some angle to each other then the magnitude of resultant of two vectors is given as
here A and B are the magnitude of two vectors and theta is the angle between them
now here we know that two vectors are of magnitude 0.25 m/s^2 each and they are inclined at angle of 45 degree
now we will plug in all data above
A = B = 0.25
So the magnitude of resultant acceleration will be 0.46 m/s^2
