A change in the physical properties like mass or texture will not cause any change in the substance because the composition of the substance will retain the same.
<u>Explanation:</u>
A change of the physical properties will affect only the size, shape and structure of the compound, it won't be affecting the composition of the compound. Since any kind of change in the physical properties of the compound will only affect the outermost structure of the compound or the size of the compound.
It will not change the bond structure and neither it will break any bonds, thus the substance will be as it is. So, there will be no change in the substance on changing the physical properties like mass or texture, as the composition and bonding in the substance will retain the same.
Answer: 2.5m/s^2
Explanation:
Mass of car = 2250 kg
Force = 5625 N
Acceleration of the car = ?
Recall that Force is the product of mass of an object and acceleration by which it moves.
i.e Force = Mass x acceleration
5625 N = 2250 kg x acceleration
Acceleration = (5625 N / 2250 kg)
Acceleration = 2.5m/s^2
Thus, the acceleration of the car is 2.5 metres per second square.
Iron rich minerals in rock pointed in one direction the switch to the exact opposite direction. what supports this idea is that Earth's magnetic field goes through pole reversals <span>

The momentum afterward will be your initial momentum (zero here) plus the momentum of the object 2.5kg*14.5m/s = 36.25kg*m/s. This will be your final momentum, mv, but now your mass must include the 2.5kg object. so your mass is 45.7+2.5 = 48.2kg. So mv=36.25 ; 48.2*v=36.25 ; v = 0.752m/s
