Answer:
12000 mph
Explanation:
Given that,
Distance read by the odometer = 120,000 miles
Duration of car, t = 10 years
We need to find the average speed of the car. Speed of an object is equal to the total distance covered divided by total time taken. So,
[tex]v=\dfrac{120000}{10}\\\\=12000\ mph[/tex]
So, the average speed of the car is 12000 mph.
Why does it rain a lot?
Answer:
Clouds are made up of tiny water droplets. ... As more and more droplets join together they become too heavy and fall from the cloud as rain. Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

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.

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.

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
At 4 seconds after starting, a cyclist is traveling 10 m/sec. At 6 seconds, he is traveling 20 m/sec. What is his average acceleration from 4 seconds to 6 seconds?
Answer:
The average acceleration of the cyclist is 5 m/s²
Explanation:
Given;
initial velocity of the cyclist, u = 10 m/s
final velocity of the cyclist, v = 20 m/s
initial time of the cyclist, t₁ = 4 seconds
final time of the cyclist, t₂ = 6 seconds
The average acceleration is given by;
[tex]a = \frac{dv}{dt}\\\\a = \frac{v-u}{t_2-t_1}\\\\a = \frac{20-10}{6-4}\\\\a = 5 \ m/s^2[/tex]
Therefore, the average acceleration of the cyclist is 5 m/s²

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]

F este forța atracției
q1 și q2 sunt taxele
r este distanța dintre sarcini

A ball starts from rest at the initial position x; = 0. The
ball has a constant acceleration of 2.4 m/s2. (a) Write
the position-time equation for the ball. (b) What is the
position of the ball at t = 1.0 s? (c) What is its position
at t = 2.0 s?
Answer:
(a) s(t) = 4.9t²
(b) s(1) = 4.9 m
(c) s(2) = 19.6 m
Explanation:
(a)
the position time equation can be formed by using 2nd equation of motion:
s = Vi t + (1/2)gt²
where,
s = position
Vi = Initial velocity = 0 m/s
t = time
g = 9.8 m/s²
Therefore,
s = (0 m/s)t + (1/2)(9.8)t²
s(t) = 4.9t²
(b)
s(1) = 4.9(1)²
s(1) = 4.9 m
(c)
s(2) = 4.9(2)²
s(2) = 19.6 m
We want to get the motion equations of a ball, and we want to use them to find the position of the ball at different times.
The solutions are:
a) P(t) = (1.2 m/s^2)*t^2b) x = 1.2mc) x = 4.8mWe know that the ball starts from rest (so the initial velocity is zero) from the position x = 0.
The ball has a constant acceleration of 2.4 m/s^2
Then the acceleration equation is:
A(t) = 2.4 m/s^2
To get the velocity equation we integrate, remember, the initial velocity is zero, so we don't have a constant of integration:
V(t) = (2.4 m/s^2)*t
To get the position equation we integrate again, and because the initial position is x = 0, we don't have a constant of integration:
P(t) = 0.5*(2.4 m/s^2)*t^2
a) The position equation is:
P(t) = (1.2 m/s^2)*t^2
b) The position of the ball at t = 1s is given by:
P(1s) = (1.2 m/s^2)*(1s)^2 = 1.2m
The ball position at t = 1s is x = 1.2m
c) Similar to the above case:
P(2s) = (1.2 m/s^2)*(2s)^2 = 4.8 m
x = 4.8m
