Answer:
33.33 m/s
Explanation:
m = 450 kg. T = 5000 N, t = 3 seconds,
let the net acceleration is a.
T = m a
a = 5000 / 450 = 11.11 m/s^2
u = 0 , v = ?
Let v be the velocity after 3 seconds.
Use first equation of motion
v = u + a t
v = 0 + 11.11 x 3 = 33.33 m/s
Answer:
Particles vibrate parallel to the direction the sound travels
When you learn something mew that trumps what you already knew
Answer:
Density
Explanation:
The factors that allows magma to push its way up includes temperature and density.
Temperature is the degree of hotness or coldness of a body
Density is the mass per unit volume.
Temperature and density combines within the asthenosphere to create convective cells by which magma is force up.
- A hot magma is less dense and it is light, therefore, it rises up to crustal levels.
- A cold magma is dense and it sinks downward.
- This cyclic exchange is what drives the movement of magma at sub-crustal levels.
