Answer: <em>4</em><em>2</em><em>.</em><em>3</em><em>2</em><em> </em><em>ms-1</em>
Explanation:
v = u+ at
v = 24.4 + ( 3.2×5.6)
v = 42.32 ms-1

Answer:</h2>
<h2>
Cohesion </h2>
Is the attraction that molecules have for others of their same type.
<h2>
Adhesion </h2>
Is the attraction that molecules have for others of different type by intermolecular forces.
A good example of both is water that can stick to itself through hydrogen bonds (cohesion) and can also stick to a glass due to adhesion.
So, while Cohesion is the force of attraction between adjacent particles within the same body, Adhesion is the interaction between the surfaces of different bodies.
Answer:
Acceleration a = 3.75 m/s^2
Explanation:
Given that
Mass M1 = mass of the truck = 2300kg
Mass M2 = mass of the SUV = 2500kg
Force applied F = 18000N
From Newton second law,
F = ma
Where a = acceleration
We must consider the entire mass involved in the system. Therefore,
F = (M1 + M2)a
Make a the subject of formula
a = F/(M1 + M2)
Acceleration a = 18000/( 2300 + 2500)
Acceleration a = 18000/ 4800
Acceleration a = 3.75 m/s^2
They are both a form of wave, yet one is a physical wave, meaning the water wave, and the other is simply a sound.
