I am pretty sure that the only statement which is true for particles of the medium of an earthquake P-wave is being shown in the option : b)vibrate parallel to the wave, forming compressions and rarefactions. As you know, it can be formed in two ways : from alternating compressions and rarefactions or primary wave. I bet you will agree with me.
Whenever an object is under free fall motion, assuming that there is no air present in its surrounding, acceleration of object will always be 9.8 m/s²
Answer:
54.55 m/s
Explanation:
From the question above,
Change in velocity = impulse/mass
Δv = I/m = Ft/m................... Equation 1
Where F = force, t = time, m = mass
Given: F = 20 N, t = 30 s, m = 11 kg
Substitute these values into equation 1
Δv = (20×30)/11
Δv = 600/11
Δv = 54.55 m/s
Hence the change in velocity of the body is 54.55 m/s
Its not Molecule or Compound
I THINK they are atom but it could also be solution Im not entirely sure
Answer:
Explanation:
We can use Newton's Second Law to solve this exercise, which states that an object of mass m subjected by a force of magnitude F will experiment an acceleration given by the formula F=ma. I our case we want the acceleration, so we can write a=F/m, and use the values given:
a=F/m=(1000N)/(1000kg)=1m/s2.
