Answer:
Horizontal Component = 129.9 km/h
Vertical Component = 75 km/h
Explanation:
When a vector is resolved on the x-axis and the y-axis, the components so formed are called its rectangular components. The component along y-axis is called the vertical component and the component along x-axis is called horizontal component. These components can be given by following formulae:
Horizontal Component = v Cos θ
Vertical Component = v Sin θ
where,
v = velocity = 150 km/h
θ = angle = 30°
Therefore,
Horizontal Component = (150 km/h)(Cos 30°)
Horizontal Component = 129.9 km/h
Vertical Component = (150 km/h)(Sin 30°)
Vertical Component = 75 km/h
What is the phase of water when its temperature is 150 °C?
A. Solid
B. Liquid
C. Gas
D. None of the above.
Answer:gas
Explanation:
The phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.
What are the phases of substance?Phase is a term used in thermodynamics to describe an amount of matter that is chemically and physically uniform or homogeneous, can be mechanically separated from a nonhomogeneous mixture, and may consist of a single material or a combination of substances.
Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another.
As the boiling point of water is 100° C, the phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.

Answer:
decreases 1/4 of the original value
If the distance between two charged particles is doubled, the force between them changes by a factor of 1/4.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force between two charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
If the distance between two charged particles is doubled, the force between them changes by a factor of 1/4.

What force is required to accelerate a 6 kg bowling ball at 2 m/s/s forward?
Answer:
12N
Explanation:
Force = mass * acceleration.
6 * 2 = 12
Taking into account the Newton's second law, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.
In first place, acceleration in a body occurs when a force acts on a body. There are two factors that influence the acceleration of an object: the net force acting on it and the mass of the body.
Newton's second law states that this force will change the speed of an object because the speed and / or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.
Mathematically, Newton's second law is expressed as:
F= m×a
where:
F = Force [N] m = Mass [kg] a = Acceleration [m/s²]In this case, you know:
F= ? m= 6 kg a= 2 m/s²Replacing:
F= 6 kg× 2 m/s²
Solving:
F= 12 N
Finally, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.

In a study, the data you collect is Habits on a Always/Sometimes/Never scale.What is the level of measurement?
Answer:
Ordinal
Explanation:
There are four levels of measurement which include the nominal, ordinal, interval, and ratio. The data collected above is ordinal data as it qualifies the data and still indicates the ordering of the data. It gives the observer an idea of the range of data collected or its rating although mathematical calculations may not be done with it.
The other forms of data include the nominal which simply qualifies the data, the interval which qualifies the data but which the differences between the data can be obtained, and of course the data has no starting point. The ratio scale which is similar to the interval scale but which the ratios between the data obtained can be compared.
A car is traveling at 100 km/h. How many minutes will it take to cover a distance of 750 km?
Answer:
7.5 minutes (you mean hours)
t = 7.5 min (if it was actually not hours than put minutes just letting u know.)
Explanation:
The first thing you have to do is know the equation; it is t = d/s, which is time = distance divided by speed. Know fill in the equation, now it will be t = 750 km/100 km/ hr ( in this min). If you divide it, then the answer will be t = 7.5 min (which it has to be hours instead of min because hours makes more sense than minutes.)
The car will take 7.5 hours to cover a distance of 750km.
What are Speed and velocity?Speed is defined as the rate over time at which an object is moving along a path, while velocity is defined as the rate and direction of motion of an object. Speed is a scalar quantity as it has only magnitude, no direction but Velocity is a vector quantity as it has both magnitude as well as direction.
Speed can be expressed as:
Speed= Distance travelled/ Time taken
Velocity can be expressed as:
Velocity= Displacement travelled/ Time taken
Both the quantities are expressed as meter per second (m/s).
If the two values are given , we can calculate the another value like in the above given information, speed of the car = 100km/hr and distance travelled by the car= 750 km.
So, Time taken= 750/100 = 7.5 hours
Thus, the car will take 7.5 hours to cover a distance of 750km.

(USE THE GRAPH) Vectors B and C and are shown in the graph. Vector B is multiplied by the scalar 92. What angle does the new vector make with the x-axis?
Answer:
The angle the new vector makes with the x-axis is 33°
Explanation:
By multiplying a vector with a scalar, we multiply the similar components of the two quantities which is the magnitude of the scalar quantity and the magnitude of the vector with the new vector formed will have a magnitude equal to the product of the two magnitudes and the same direction of the original vector as follows;
The magnitude of the vector B = 5.6
The magnitude of the scalar = 92
The product of the two magnitudes = 5.6 × 92 = 515.2
The magnitude of the new vector = 515.2
The direction of the new vector = 33° South of West
Therefore, the angle the new vector makes with the x-axis = 33°.
A city bus travels six blocks east and eight blocks north east wok is 100 m long is a bus travels as distance and 15 minutes what is the average speed on the bus
Answer:
the average speed on the bus = 1.55 m/s
Explanation:
From the information we are being provided with ;
a city block travels 6 blocks due east
and 8 blocks due north
the length of the individual blocks = 100m
As such their respective distance will be
distance (d) traveled due east direction by bus = 6 × 100 = 600 m
distance (d) traveled towards the north direction by bus = 8 × 100 = 800 m
The total distance covered = (600+ 800)m
= 1400 m
However, it requires 15 minutes to travel this distance by bus.
Thus,
the average speed = distance/ time
the average speed on the bus = 1400 m / (15 × 60) s
the average speed on the bus = 1400 m / 900 s
the average speed on the bus = 1.55 m/s

Answer:
Explanation:

5p = 8p + 18 <-- Moving constants to one side; add the same number of +14 to both sides.
-3p = 18. <-- The same thing with the variable itself.
p = -6 <-- Divide both sides by negative 3.
a 50-kg object moving at 12 m / s has a momentum of 600 kg m / s what is the mass of an object moving at 4 m/s has the same momentum
Explanation:
p=mv
600kgms-1=m × 4ms-1
m=600kgms-1/4ms-1
m=150kg
The mass of the object which has momentum of 600kgm/s with the velocity of 4m/s is 150kg.
What is Momentum?Momentum is the product of the mass and velocity of the object. Momentum is the quantity of motion which is made up of the amount of matter moved and the velocity at which it moves. Momentum is a vector quantity because it has both the magnitude and direction. The SI unit of momentum is kg.m/s (kilogram meter per second).
p = m × v
p = momentum of the object,
m = mass of the object,
v = velocity of the object
600kgm/s = m × 4m/s
m = 600/ 4
m = 150kg
Therefore, the mass of the object will be 150kg.

A car, initially traveling 24.0ft/s, steadily speeds up to 58.0ft/s in 5.40s. Determine all unknowns and answer the following question.
How far did the car travel during this time?
Answer:
acceleration = 6.29 ft^2/s
distance traveled by car = 405 ft
Explanation:
formula 1 : u = v - (a*t)
where u = initial velocity
v = final velocity
a = acceleration
t = time.
solving for acceleration.
24 = 58 - (a*5.4)
a = (58 - 24)/ 5.4
a = 340/ 54 = 6.29 ft^2/s
formula 2: v = d/t - (a*t/2)
58 = d/5.4 - ((340*54)/20)
d = 405 ft
