What is car toy?Many of us do not pause to contemplate the importance of play in the lives of children, whether they are our own or the children of friends and relatives. We just take it for granted that kids spend their free time driving toy trucks about or pretending to be dragons (or both), and although it's amusing (certainly for them and occasionally for us), we don't give it much thought beyond that.
It's a great time to start playing with cars, dump trucks, and other vehicles. Not that they'll need much convincing: boys, in particular, appear to be captivated to anything that includes wheels long before their first birthday. which curves down to the shorter box, and line.
Therefore, the correct option is option C.

Two objects, A and B, are 10 m apart. Objects C and D are 20 m apart. The gravitational attraction between objects C and D is greater than the attraction between objects A and B. Explain the reason for the difference in gravitational attraction.
Answer:
[tex]F=\frac{Gm_1m_2}{r^2}[/tex]
where , F = Gravitational force
G = Gravitational constant
[tex]m_1[/tex] = mass of first object
[tex]m_2[/tex] = mass of second object
r = distance between the two objects
As Gravitational force is inversely related to the distance between two objects, lesser is the distance , more will be the gravitational force. As distance between C and D is more , the force shoulld have been less. That means the product of the masses of the objects C and D is more than the product of the masses of the objects A and B.

The strength of the electromagnet increases.
The electromagnet turns off.
The poles of the electromagnet reverse.
Turn off the battery supply.
Place a magnetic core inside the coll of wire.
Change the direction in which the current flows.
Answer:
1) The strength of the electromagnet increases → Place a magnetic core inside the coil of wire
2) The electromagnet turns off → Turn off the battery supply
3) The poles of the electromagnet reverse → Change the direction in which the current flows
Explanation:
when current passes through a coil it behaves a an electromagnet.
Magnetic field strength is given by
B = μ N I
N is no of turns and
I is the current through coil
μ is permeability of the medium or core in the coil.
1). Magnetic core increase permeability μ so it will strengthen magnetic field:
B = μ N I
2). When the battery turns off current becomes zeroi.e I=0
So B = μ N * 0
⇒ B = 0
so electromagnet turns off
3). Direction of magnetic field can be determine by right hand rule, i.e curl the fingers in the direction of current, thumb will point in the direction of north pole.
so changing current direction will change direction of magnetic field.

If the same strength force is exerted on two objects why might they be affected differently?
Answer:
Due to their mass
Explanation:
If the same strength force is exerted on two objects they might be affected differently due to their mass.
The way objects reacts to a force impact is largely dependent on their mass.
The mass of an object is the amount of matter it contains.
According to the Newton's second law of motion, the force applied on a body is directly proportional to the product of its mass and acceleration.
Force = mass x acceleration
Therefore, the way a force acts on a body is a function of its mass.

Thank you so much
Answer:
Blue
Explanation:
The colors of the rainbow are known by the acronym; ROYGBIV.
This is;
Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
From research, their respective wavelengths on the average are;
Red: 665 nm
Orange; 630 nm
Yellow; 600 nm
Green; 550 nm
Blue; 470 nm
Indigo; from 445nm to 464 nm
Violet; less than 400 nm
This means that from Red to Violet in that order, wavelength is decreasing in a descending order.
Now in refraction, the light with shortest wavelength will be bent the most while that with longest wavelength will be bent the least.
Thus, violet bends the most.
However, violet is not included in the options. So the next one that will bend the most after violet among the options given is Blue.

A car advertisement claims their car can go from a stopped position to 60 miles per hour in 5 seconds. The advertisement is describing the
car’s
Answer:
Acceleration
Explanation:
The advertisement is describing the acceleration of the car.
Acceleration is the rate of change of velocity per unit of time. It can be expressed mathematically as;
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Any quantity that specifies the rate of change of velocity of a body within a given time frame is describing its acceleration.

An object experiences an acceleration of 8.5 m/s^2 over a distance of 300 m. After that acceleration it has a velocity of 400 m/s. What was its velocity before being accelerated? *
Answer:
393.6m/s
Explanation:
Given parameters:
Acceleration = 8.5m/s²
Distance = 300m
Final velocity = 400m/s
Unknown:
Initial velocity = ?
Solution:
To solve this problem, we use the expression below;
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
So;
v² - 2as = u²
u² = v² - 2as
u² = 400² - (2 x 8.5 x 300)
u = 393.6m/s
Given parameters:
Acceleration = 0.0m/w
Initial velocity = 0m/s
Final velocity = 00m/s
Unknown:
Distance traveled = ?
Solution:
To solve this problem, we use the expression below:
q0 = y + 0w
W is the final velocity
Y is the initial velocity
C is the acceleration
P is the distance
0² = 0² + (0 x 0.0 x S)
000 = 00.0S
S = 0m

Daniel steps on the gas pedal of his car, and the engine increases its performance from zero to 2700 rpms (rotations per minute). What are the frequency and period?
[Hint: frequency is cycles per second]
Explanation:
The frequency of the engine is given by :
[tex]f=\dfrac{rpm}{60}[/tex]
We have, the engine increases its performance from zero to 2700 rpms.
Frequency,
[tex]f=\dfrac{2700}{60}\ \text{cycles per second}\\\\f=45\ \text{cycles per second}[/tex]
The time period of the engine is given by :
T = f/f
So,
[tex]T=\dfrac{1}{45}\ s\\\\T=0.023\ s[/tex]
Hence, the required frequency and the period is 45 cycles/second and 0.023 seconds respectively.
A kettle transfers 6000 J of energy electrically. 1500 J of this is wasted. What is the efficiency of this kettle?
Answer:
Effi = 75 %
Explanation:
That is, the 6000 [J] is electrical energy that is transferred to the liquid, of that amount of energy 1500 [J] is dissipated or lost.
That is, from that amount of energy the difference between the energy that is supplied and the one that is lost is the energy that absorbs the liquid in the kettle.
[tex]Q=6000-1500\\Q=4500[J][/tex]
That is 4500 [J] enter the liquid that is heated.
Efficiency can be calculated as the amount of energy that the liquid receives over the energy that is supplied.
[tex]Effi = 4500/6000\\Effi = 0.75[/tex]

This scenario is directly related to the Inertia of direction, which states that an object will stay moving in the same direction unless a force acts on it.
If you need to add more to the answer above, you can probably say something about how the sudden change in direction will cause your body to want to continue on in the direction it was originally going, so the car veering suddenly will cause you to be violently pulled in it's direction.
I like to think of it like a car crash, the reason why head-on collisions are so deadly are because the car will halt but your body will continue moving at the same speed the car was going.
That's my best guess. Hope this helps! :)

Answer:
A class is a blueprint from which you can create the instance, i.e., objects. An object is the instance of the class, which helps programmers to use variables and methods from inside the class. A class is used to bind data as well as methods together as a single unit. Object acts like a variable of the class.include transport systems; solar systems; telephone systems; the Dewey Decimal System; weapons systems; ecological systems; space systems; etc. Indeed, it seems there is almost no end to the use of the word “system” in today's society.One of the thermodynamic properties of a system is its internal energy, E, which is the sum of the kinetic and potential energies of the particles that form the system. The internal energy of a system can be understood by examining the simplest possible system: an ideal gas.A swinging pirate ship ride at a theme park.

The amount of friction depends on the weight of the objects pressing together.
Answer:
The amount of friction depends on the force pushing the surfaces together. If this force increases, the hills and valleys of the surfaces can come into closer contact. The close contact increases the friction between the surfaces. Objects that weigh less exert less downward force than objects that weigh more.
Explanation:
Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth.

Answer:
The crate should be released 3,080 m in front of the target
Explanation:
Horizontal Launch
When an object is thrown horizontally with a speed v from a height of h, it describes a curved path ruled by gravity until it hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
The airplane drops a crate horizontally from a height of h= 2,750 m when flying at v=130 m/s. The range or maximum horizontal distance the crate reaches is:
[tex]\displaystyle d=130\cdot\sqrt{\frac {2*2,750}{9.8}}[/tex]
Operating:
[tex]\displaystyle d=130\cdot\sqrt{561.2245}[/tex]
d = 3,080 m
The crate should be released 3,080 m in front of the target
