Answer:
12 N
Explanation:
Given,
Mass ( m ) = 3 kg
Acceleration ( a ) = 4 m/s^2
To find : Force ( F ) = ?
Formula : -
F = ma
F
= 3 x 4
= 12 N
Therefore, the force acting on the object is 12 N.
They ALL do.
Every object with mass has a gravitational field ... just as long as its mass is somewhere between an electron and a supercluster of galaxies.
Answer:
Protraction and retraction are opposite of each other.
Explanation: For example, here are difference between the two.
1. Protraction occurs when the lower has is pushed forward to stick to the chin, Retraction, being the opposite pulls the lower jaw backward.
2. Scapular retraction, this help to move the shoulder blade(scapula) towards the spine, also Protraction being the opposite help to move the shoulder blade away from the spine.
Wavelength = 1/frequency thus wavelength =1/30000
The energy travels in a disturbance, in an ocean that disturbance is a wave, so the wave makes energy and moves it through the water
