Answer:
Wave speed = Wavelength x Frequency
26 m/s = Wavelength x 49
Divide by 49 to find the wavelength:
The wavelength is approximately 0.53
Let me know if this helps!
Weight=mg
g=GM/r^2
g on venus is 0.80w as radius is kept constant
m of object is kept constant
w α g
w(venus( is 0.8w
The force of gravity F_g will act downwards.
Normal force F_N will act upwards equal to the force of gravity.
A force due to uniform acceleration F_a will act upwards to move the elevator upwards.
Thus, figure E is the correct answer.
They are attractive
They don’t depend on charge
Answer:
P=2736 Pa
Explanation:
According to Newton we have that:
∑
A force is exerted by the elevator to the suitcase, according to 3th Newton's law an equal force but in the opposite direction will appeared on the suitcase, that is:
∑
We know that the pressure is given by:
