Answer:
94.67 N
Explanation:
Consider a free body diagram with force, F of 41 N applied at an angle of 37 degrees while the weight acts downwards. Resolving the force into vertical and horizontal components, we obtain a free body diagram attached.
At equilibrium, normal reaction is equal to the sum of the weight and the vertical component of the force applied. Applying the condition of equilibrium along the vertical direction.
Substituting 70 N for W, 41 N for F and 
for 37 degrees
N=70+41sin37=94.67441595 N and rounding off to 2 decimal places
N=94.67 N
ohm's law V=IR
V=24x11=240+24=264V

Answer:
b) Springs oscillate with the same frequency,
Explanation:
expression for frequency of vibration of mass hanging from a spring is given as follows
f = 
k is force constant of spring and m is mass vibrating .
In the present case, if mass stretches the spring by x and remains balanced
mg = k x
g and x are same for both cases
will also be same for both cases .
Hence frequency of vibration will also be same for both the balls .
Answer: They travel away from the focus of the earthquake in all directions.
Explanation:
The vibrations produced by Earthquake are called seismic waves. seismic waves travel from the point where fault occurs. The maximum intensity is about the focus of the fault. These waves travel away from the focus in all directions.
Seismic waves are both transverse (S waves) and longitudinal (P waves). The P and S waves can travel through the Earth where as the surface waves travel above or near the Earth's surface.
