Here's a explanation!
Let's solve your equation step-by-step.


Step 1: Multiply both sides by x.


(Divide both sides by 4).


Take the root.
ANSWER!

Hopefully, this helps you!!

As per FBD while its accelerating upwards
we can say that

here normal force is given as


now mass is given as


now we will have


Now while accelerating downwards we can say by FBD

again plug in all values


We would just get three times heavier.
weight = mass x gravity (9.8 m/s/s)

Answer:
A.They alternately compress and pull apart the particles in matter.
B. They are the first waves detected after an earthquake.
Explanation:
P-waves, also known as a compressional wave is the wave that shakes the ground in the same and opposite direction of the wave i.e. back and forthe motion of the ground. They compress and pull apart the material alternatively. The disturbances due to these waves have small magnitude thus making them non destructive. These waves travel at faster speed as compared to other seismic waves and thus help in detecting the earthquake. These wave can travel through liquid, solid and gases.
