A 1400-kg car is moving at a speed of 25 m/s. How much kinetic energy does the car have?
Answer:
Kinetic energy=1/2mvsquare
1/2 x 1400 x 25 x25
Therefore kinetic energy= 437500Joules
Explanation:
Answer:
437,500 Joules
Explanation:
KE= 1/2 × M
x V^2, where
M = Mass,
V = Velocity
KE = 1/2 × 1400 × 25^ 2
KE= 1/2 × 1400 × 625
KE = 437,500 Joules.

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?
How can a model be created to predict how forces affect objects at a distance?
Answer:
Gravitational force increases as the masses of the objects increase and decreases as the distance between the objects increases. Balanced forces acting on an object cause no change in the motion of the object. When unbalanced forces act on an object, the sum of the forces is not equal to zero.

What are the three main parts that make up GAIA? Briefly explain and describe each.
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

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
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.

56. What is the range of magnitudes that can be attained from the
combination of forces with magnitudes of 7 and 5 N?
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
Calculate the normal force acting on a 150 kg cart that is at rest.
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]

2 sfere electrizate cu sarcini egale,situate in vid la distanta de 10 cm una de alta,interactioneaza cu o forta de 0,1 N.Aflati sarcina electrica a uneia din sfere
Răspuns:
1,054 × 10 ^ -6Combombs
Explicaţie:
Conform legii coloumbs, forța de atracție sau repulsie între sarcină este exprimată ca;
F = kq1q1 / r²
F este forța atracției
q1 și q2 sunt taxele
r este distanța dintre sarcini
Deoarece taxele sunt egale, q1 = q2 = q
Ecuația devine
F = kq² / r²
Dat
F = 0,1N
r = 10cm = 0,1m
Necesar
q
Înlocuiți parametrii dați în formulă;
0,1 = 9 × 10 ^ 9q² / 0,1
0,1 × 0,1 = 9 × 10 ^ 9q²
0,01 = 9 × 10 ^ 9q²
q² = 0,01 / 9 × 10 ^ 9
q² = 0,01 / 9.000.000.000
q² = 1,11 × 10 ^ -12
q = √1.11 × 10 ^ -12
q = 1,054 × 10 ^ -6Combombs
Prin urmare, sarcina electrică pe una dintre sfere este de 1,054 × 10 ^ -6Combombs
