Calculate the normal force acting on a 150 kg cart that is at rest.
Answers
Answer:
N = 1471.5[N]
Explanation:
We must remember that anybody lying on a horizontal surface, the normal force is defined as the vector corresponding to the force of equal magnitude to the product of mass by gravity, but in the opposite direction to the vector of weight.
To calculate the magnitude of the normal force (equal to weight), we can perform the product of mass by gravity.
[tex]w =m*g\\[/tex]
where:
w = weight [N] (units of Newtons)
m = mass = 150 [kg]
g = gravity acceleration = 9.81 [m/s²}
[tex]N=w[/tex]
[tex]N=150*9.81\\N = 1471.5[N][/tex]

gold has a density of 19300 kg/m3 calculate the mass of 0.02m3 of gold in kilograms
Answers
Mass if a substance is the product of its volume and density. The mass of gold of 0.02 m³ with a density of 19300 kg/m³ is 386 kg.
What is density?Density of a substance is the measure of its mass per unit volume. Thus, it says how much denser the object is in a given volume. Density of a substance is dependent on its bond type, temperature and pressure beside the volume and mass.
Volume can be defined as the space occupied by the substance. Larger the volume , less dense the substance is. However as the mass increases volume also increases.
Mass of an object is the product of its volume and density.
Given the volume of gold = 0.02 m³
density = 19300 kg/m³.
mass = volume × density
= 0.02 m³ × 19300 kg/m³
= 386 kg
Therefore, the mass of gold is 386 Kg.

56. What is the range of magnitudes that can be attained from the
combination of forces with magnitudes of 7 and 5 N?
Answers
Answer:
Explanation:
Given the magnitude of the forces, 7N and 2N, the minimum combining force acting on the forces are when the force's is acting in opposite direction.
Magnitude of the force in opposite direction is 7N - 5N = 2N
The maximum combining force occurs when they act in the same direction. Magnitude of the force in the same direction is 5N+7N = 12N
Hence the range of magnitude requires is 2N≤F≤12N

Question 13 Which of the following will NOT occur when water undergoes a physical change? The motion of the molecules increases. The molecules form new chemical bonds. c The molecules become less closely packed. D The kinetic energy of the molecules increases
Answers
Answer:
the molecules form new chemical bonds
Explanation:
The circumstance which will not occur when water undergoes a physical change is that the molecules form new chemical bonds. Thus, the correct option for this question is B.
What do you mean by Physical change?Physical change may be defined as a type of change within the compound or things that significantly do not change the chemical properties of the matter. It usually involves the process of transition from one state to another.
When water undergoes a physical change means liquid to solid, solid to liquid, or gas, the motion of the molecules, kinetic energy, and density alter with respect to the state of matter. So, all these attributes are classified into the category of physical change.
Therefore, the molecules forming new chemical bonds is the option that will not occur at any point in time when water undergoes a physical change. Thus, the correct option for this question is B.

By measuring the potential energy of an object relative to the ground, and the object's mass, you can calculate its speed when it hits the ground. Explain why you can do this.
A.because gravitational potential energy can convert to elastic potential energy
B.because gravitational potential energy can convert to kinetic energy
C.because the gravitational potential energy can convert to sound energy
D.because gravitational potential energy can convert to electric potential energy
Answers
Answer:
B.because gravitational potential energy can convert to kinetic energy
Explanation:
You can calculate the speed as it hits the ground because gravitational potential energy can convert to kinetic energy.
In this way, total energy can be conserved.
We can equate the kinetic energy and potential energy. From this we can solve for the velocity. This way, we know that the potential energy is changing to kinetic energy.Answer: B

4)A ball of mass 1.2 kg is dropped from a height of 30 m. As it falls, 25% of its initial gravitational potential energy is
transferred to thermal energy. What is the kinetic energy of the ball just before it hits the ground?
Answers
Eg = 353.16 J
Eh = Eg * 0.25
Eh = (353.16 J) (0.25)
Eh = 88.29 J
Ek = Eg - Eh
Ek = (353.16 J) - (88.29)
Ek = 264.87 J
Therefore the kinetic energy just before the ball hits the floor is 264.87 J

What are the three main parts that make up GAIA? Briefly explain and describe each.
Answers
Answer:
GAIA is composed of three main parts; the astrometry instrument, the photometric instrument, and the radial-velocity spectrometer. The astrometry instrument is used to determine the angular positions of stars to better measure their distances and motions. The photometric instrument measures the luminosity of stars to help determine stellar properties such as temperature, mass, age, and what elements the stars are made up of. The radial-velocity spectrometer will determine the speed of galactic objects along the line of sight.
Explanation:
The three main parts that make up GAIA are :
Astrometry instrument Photometric instrument Radial-velocity spectrometerThe functions of the main parts of GAIA are as follows
The astrometry instrument : It is used to determine the angular positions of the star which aids in the measure of the stars distances and positions.Photometric instrument : It is used to determine the level of luminosity of the stars which aids in determining the age, temperature, mass and components of the stars. Radial-velocity spectrometer : It is used to determine the speed of objects 9 galactic ).Hence we can conclude that the three main parts that make up GAIA are astrometry , photometric instrument and radial-velocity spectrometer
