Answer:
The correct answer is C
Explanation:
Change is momentum can be described as the change in the product of mass and velocity of a body. Every moving object as a momentum and the higher the momentum of this object, the harder it is to stop. Impulse (a force), which is sometimes used to describe change in momentum can be described as the product as force multiplied by time.
From the description above, it can be deduced that an increase in impulse can lead to a greater change in momentum. And an increase in impulse can be brought about by an increase in the time it takes a body to be brought to rest after collision. And since the car that hit the water barrels was brought to rest at a longer time, it has a greater change in momentum
The dimension of force, F is ML/T².
<h3>What is force?</h3>
Force is a push o push agent which causes a change in the state of rest or motion of an object.
From a fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass.
Mathematically; acceleration ∝ F/m
F = ma
dimension of Mass = M
dimension of acceleration = L/T²
dimension of force, F = ML/T²
In conclusion, the dimension of force is obtained from the dimensions of mass and acceleration.

Answer:
6000 cm<em>²</em>
Explanation:
let width of rectangle = 
Using Pythagorean theorem,
+<em> 50² = 130²</em>
<em /><em> = 130² - 50² </em>
<em /><em> = 14400</em>
<em /> <em>= 120 cm</em>
area of rectangle <em>=</em> length x width
<em>=</em> <em>120 x 50</em>
<em>= 6000 cm²</em>
Answer:
16 Watts
Explanation:
P = VI, where V is the voltage and I is the current (of the lightbulb)
V = 8 volts, I = 2 amps
P = 8 * 2 = 16 Watts
Through gases as the bonds are tightly bound. Mechanical waves travel by vibrating through the medium so the more tight the bonds , the faster the waves.
