According to Newton’s second law of motion, what is equal to the acceleration of an object?
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.
14.Which of the following is TRUE of a body in equilibrium.
I. The sum of the forces in one direction is equal to the sum of the
forces in the opposite direction
II. The sum of the clockwise forces is equal to the sum of the
anticlockwise forces
III. The sum of the clockwise moments is equal to the sum of the anticlockwise moments
a) I only
b) II only
c) I and III only
d) I, II and III
Answer:
Explanation:
One
All three statements are saying exactly the same thing.
1. one direction forces = opposite direction forces. Note forces have direction. Always remember that forces have direction and you must always say what that direction is.
2. Two is saying the same thing as one. It is just that 2 is more specific about what the direction is. Clockwise is different from anti clockwise.
3. moments are forces and distances. Forces always have direction. Distances sometimes do not. At your level of study, I don't think it does. Later on, you will learn the word displacement which always has direction and that direction must be stated.

15 We are told to answer just 1 or 2 questions from the same student's posting. There are 4 here, so I'm going to give you just brief answers.
You should realize by now that a loaded bus has it's center of gravity raised. The answer is B
16 A is true.
Technically anything to do with turning is a torque.
D is also true.
C is better worded than B. I would pick B as the odd one out.
17
This is rotating so they must be on the same side of the pivot point. The moments add.
20*3 + 10*2 = 60 + 20 = 80 Newton Meters. Notice C has the right numbers associated with it, but the distance is divided into a Newton. Wrong answer.
In this series of questions, moments are defined as Force * Distance.

what is the mass of an object if a 30 N force makes it accelerate at 6 m/s2
Answer:
5 kg
Explanation:
Acceleration = 6 m/s^2
Force = 30 N
Force = mass * acceleration
mass = force / acceleration
mass = 30 / 6
mass = 5 kg

How does Density depend on the type of object being measured ?
Answer:
ways to exaplined
Explanation:
Density is calculated by
dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.

The density of iron is 7.97 g/cm. Express it in Sl unit.
Answer:
[tex]d=7970\ kg/m^3[/tex]
Explanation:
Given that,
The density of iron is 7.97 g/cm³.
We need to find the density in SI unit. The SI unit of density is kg/m³.
We know that,
1 kg = 1000 g
1 m = 100 cm
So,
[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]
So, the density of the iron is [tex]7970\ kg/m^3[/tex].

The momentum of a 5-kilogram object moving at 6 meters per second is-
The momentum of an object is 30 kgm/s . This can be calculated by using momentum formula see description below.
What is momentum?It is defined as the product between mass and velocity. Its symbol is p.
It is given by:
p = m * v
What information do we have?
Mass = 5kg
Velocity = 6 m/s
To find:
Momentum=?
On substituting the values:
p = m * v
p =5 kg * 6 m/s
p = 30 kgm/s
Thus, the momentum of an object is 30 kgm/s.
