Answer:
The definitions of mass, energy, time and space as used in Physics are circular
The Conservation of Mass and Energy
The definition of zero is not sufficiently defined in Physics
Newton’s Laws of Motion are related by Calculus
Knowing the terms of Physics is most important.

Answer:

Explanation:
Since the particle is experimenting a constant acceleration, the displacement can be found by using this formula:

Since
, the equation is simplified to this form:

Then, the displacement is now isolated:

<span>Basaltic magma (properly called mafic magma) forms in areas of the mantle where silica (SiO2) is low, but iron and magnesium is high. This usually and most famously occurs along spreading ridges, where oceanic crust is formed, but can occur anywhere -- including surface volcanoes, which can form flood basalts as we commonly know them.
hope it helps
and can you help me with some questions as well? f you dont mind

Answer:
v = 719.2 m / s and a = 83.33 m / s²
Explanation:
This is a rocket propulsion system where the system is made up of the rocket plus the ejected mass, where the final velocity is
v - v₀ =
ln (M₀ / M)
where v₀ is the initial velocity, v_{e} the velocity of the gases with respect to the rocket and M₀ and M the initial and final masses of the rocket
In this case, if fuel burns at 75 kg / s, we can calculate the fuel burned for the 10 s
m_fuel = 75 10
m_fuel = 750 kg
As the rocket initially had a mass of 3000 kg including 1000 kg of fuel, there are still 250 kg, so the mass of the rocket minus the fuel burned is
M = 3000 -750 = 2250 kg
let's calculate
v - 0 = 2500 ln (3000/2250)
v = 719.2 m / s
To calculate the acceleration, let's use the concept of the rocket thrust, which is the force of the gases on it. In the case of the rocket, it is
Push = v_{e} dM / dt
let's calculate
Push = 2500 75
Push = 187500 N
If we use Newton's second law
F = m a
a = F / m
let's calculate
a = 187500/2250
a = 83.33 m / s²
A :-) A.a.) Given - u = 0.00 m/s
v = 10.0 m/s
t = 1.5 sec
m = 75 kg
Solution -
a = v - u by t
a = 10 - 0 by 1.5
a = 10 by 1.5
a = 6.6 m/s^2
A.b.) sorry ! I don’t no how to do this question
