Answer:20ohms
Explanation:
1/R=1/40 + 1/40
1/R=(1+1)/40
1/R=2/40
1/R=1/20
Cross multiplying we get R=20ohms
Something stopped the force and was able to recreate the same amount of force to send it back to her. Example: A pole
Explanation:
We have,
Mass of an object is 0.5 kg
Force constant of the spring is 157 N/m
The object is released from rest when the spring is compressed 0.19 m.
(A) The force acting on the object is given by :
F = kx
(B) The force is simply given by :
F = ma
a is acceleration at that instant

Answer:
Speed = 300 m/s
Explanation:
Given the following data;
Frequency = 30 Hz
Wavelength = 10 m
To find the speed of the wave;
Mathematically, the speed of a wave is given by the formula:
Substituting into the formula, we have;
Speed = 300 m/s
