Question

which has more inertia, 5 kg of water or 6 kg of carbon steel?
o a water
o b steel
o c they have the same
o d inertia is my aunts name
question 2 (1 point)
force was defined in section 3.10 as a push or a pull that acts on an object in order to make the object move or to make it move faster or slower. in
other words, a force causes an object to accelerate (f = m*a).
o true
o false
question 3 (1 point)
a block of wood has a mass of 1.25 kg. how much force does it exert on the ground?
the normal force is mass (kg) multiplied by the acceleration due to gravity (g), where g
= 9.8 m/s²
o a 12.25 n.
o b 12n
o c 1.25n
o d 9.8m/s

Explanation:

Step1: Understand the concept of inertia

Inertia is directly related to mass. The greater the mass, the greater the inertia.

Step2: Compare the masses

We have 5 kg of water and 6 kg of carbon steel. Since \(6>5\).

Force is indeed defined as a push or pull that causes an object to accelerate, and the formula \(F = m\times a\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration) is correct for this relationship.

Step1: Use the formula for normal force

The formula for normal force \(F = m\times g\), where \(m = 1.25\space kg\) and \(g=9.8\space m/s^{2}\)

Step2: Calculate the force

\(F=1.25\times9.8 = 12.25\space N\)

Answer:

B. Steel
