Answer:
Impulse = 80Ns
Explanation:
Given the following data;
Mass = 3kg
Force = 20N
Time = 4 seconds
To find the impulse experienced by the object;
Impulse = force * time
Impulse = 20*4
Impulse = 80Ns
Therefore, the impulse experienced by the object is 80 Newton-seconds.
I would say B because the rest of them are false.
Because Saturn is made of gas
Saturn is smaller than Jupiter
And it takes 29 years for Saturn to orbit the sun
Hope This Helps! Have A Nice Day!!
Explanation:
speed of wave
v = wavelength x frequency
since frequency is f = 1/Period then
v = wavelength : Period
v = 10 cm/ 0.2 s = 50 cm/s
v = 0.5 m/s
Answer:
B
Explanation:
if you sit up straight you will have a proper posture
