Answer: A, B, C

Explanation: its either those:)

The magnitude of the change in the object's momentum will be equal to 80 N-s. Hence, option C is correct.

The momentum is the result of a particle's velocity and its mass. Force and motion, meaning it has both magnitude and the direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.

The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.

As per the given information in the question,

The initial momentum of the system is 0.

F = ma

a = F/m

a = 10/6

a = 1.67 m/s²

Use the equation of motion,

v = u + at

v = u + (1.67)(8)

v = 13.33 m

Then the momentum will be,

p = mv

p = 6 × 13.33

p = 80 N-s.

Explanation:

yan po ang answer

Answer:

a.    -For example, when you go to the supermarket with your parents and they let you drive the cart. You step on the back and push off which lets you get far in the isle, but in a bit you start slowing down

and eventually stop at all.

b. -First, when a car is driving the wheels meet friction all the time, as that happens the wheels get a bit hot.

-Second, when you are cold you rub your hands together fast until they are warm.

c.-First, you wouldn't be able to land an airplane correctly and it would be very, very hard to stop it from moving, as well as the car .

-We wouldn't be able to ice skate, we wouldn’t be able to slow down and turn normally.

Explanation:

(a) Friction is the force that opposes the rubber tyre from sliding on the road surface. This friction avoids skidding of vehicles. Applications of breaks in the vehicle to stop it- Friction braking is the most widely used braking method in vehicles.

(b) When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat). This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire.

(c)

"Force that resists the sliding or rolling of one solid object over  another." Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

"Kinetic energy is a form of energy that an object or a particle has by reason of its motion." If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

"Thermal energy refers to the energy contained within a system that is responsible for its temperature." Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process.

Answer:

The acceleration of textbook is downward at the slowest rate.

(a) is correct option.

Explanation:

Given that,

The object is accelerating downward at the slowest rate.

(a). a textbook falling onto the surface of the moon

(b). a flower pot that has been pushed out a window

(c). a pebble falling off a cliff through the air

(d). a baseball thrown from third base to first base

We know that,

Acceleration :

Acceleration is the product of mass of object and gravity.

[tex]a=mg[/tex]

We need to find the accelerating downward at the slowest rate

According to given data,

Acceleration depends upon weight and gravity.

We have some example of free fall.

(b), (c) and (d) are the example of free fall.

In which the gravity is same.

But in option (a) textbook falling onto the surface of the moon

We know that,

The gravity on the moon is less than the earth.

So, we can say that the acceleration of textbook is downward at the slowest rate.

Hence, The acceleration of textbook is downward at the slowest rate.

(a) is correct option.

Remember, there's 2 types of accelaration formula.

1st formula :

a = ( final speed - initial speed ) ÷ time

2nd formula :

resultant force (f) = mass × a

or

a = resultant force (f) ÷ mass

So the ans shld be,

a = 50 x 150

= 7500 m/s²

The acceleration of the body is 0.33 m/s².

Acceleration of an object having mass is defined as the net force acting on the object per unit mass.

Here,

Mass of the body, m = 150 kg

Force acting on the body, F = 50 N

The net force acting on an object is defined as the product of mass and acceleration of the object.

The expression for the net force acting on the body is given by,

F = ma

Therefore, the acceleration of the body,

a = F/m

Applying the values of F and m,

a = 50/150

a = 0.33 m/s²

Hence,

The acceleration of the body is 0.33 m/s².

Answer:

Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.

Explanation:

The three options are 1,3 and 5 Moving the balls closer together. The distance decreases and forces increase.

The gravitational force ia s type of force has the ability attracts any two objects with mass. Gravitational force tries to pull two masses towards each other.

The value of the gravitational force is given by;

[tex]F_g=\frac{ Gm_ 1m_2}{r^2}[/tex]

It is observed that the gravitational force is directly propotional to the product of mass and inversly propotional to the square of the distance between them.

So, the correct options are :

(1) Moving the balls closer together. The distance decreases and forces increase.

(3) Wrapping the soccer ball in layers of duct tape will also increase force because the mass will increase.

(5) Similarly, putting the baseball in a plastic case will increase mass, and hence force increases.

Hence the three options are 1,3 and 5.

The 10-meter long rod of an SR-71 airplane expands 0.02 meters (2 centimeters) when plane flies at 3 times the speed of sound.

Explanation:

From Physics we get that expansion of the rod portion is found by this formula:

[tex]\Delta l = \alpha\cdot l_{o}\cdot (T_{f}-T_{o})[/tex] (Eq. 1)

Where:

[tex]\Delta l[/tex] - Expansion of the rod portion, measured in meters.

[tex]\alpha[/tex] - Linear coefficient of expansion for titanium, measured in [tex]\frac{1}{^{\circ}C}[/tex].

[tex]l_{o}[/tex] - Initial length of the rod portion, measured in meters.

[tex]T_{o}[/tex] - Initial temperature of the rod portion, measured in Celsius.

[tex]T_{f}[/tex] - Final temperature of the rod portion, measured in Celsius.

If we know that [tex]\alpha = 5\times 10^{-6}\,\frac{1}{^{\circ}C}[/tex], [tex]l_{o} = 10\,m[/tex], [tex]T_{o} = 0\,^{\circ}C[/tex] and [tex]T_{f} = 400\,^{\circ}C[/tex], the expansion experimented by the rod portion is:

[tex]\Delta l = \left(5\times 10^{-6}\,\frac{1}{^{\circ}C} \right)\cdot (10\,m)\cdot (400\,^{\circ}C-0\,^{\circ}C)[/tex]

[tex]\Delta l = 0.02\,m[/tex]

The 10-meter long rod of an SR-71 airplane expands 0.02 meters (2 centimeters) when plane flies at 3 times the speed of sound.

Summary of Photorealism

The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. The exactness was often aided further by the use of an airbrush, which was originally designed to retouch photographs. The movement came about within the same period and context as Conceptual art, Pop art, and Minimalism and expressed a strong interest in realism in art, over that of idealism and abstraction. Among several male practitioners of Photorealism there is an interest in themes of machinery and objects of industry such as trucks, motorcycles, cars, and even gumball machines, whereas Audrey Flack, the sole female practitioner, infuses her works with greater emotionality and the transience of life. Ultimately, the Photorealists were successful in attracting a wide audience, but they are often overlooked by art historians as an important avant-garde style.

Yes, the car will be able to stop before it reaches the truck.

Explanation:

[tex]u=\text{Initial velocity of the car}=\dfrac{72}{3.6}=20\ \text{m/s}[/tex]

[tex]t=\text{Time}=0.5\ \text{s}[/tex]

[tex]s=\text{Displacement}[/tex]

From the laws of motion we have

[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=20\times 0.5+0\\\Rightarrow s=10\ \text{m}[/tex]

The car will travel 10 m in 0.5 seconds

[tex]a=\text{Acceleration}=-2.5\ \text{m/s}^2[/tex]

[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{0^2-20^2}{2\times -2.5}\\\Rightarrow s=80\ \text{m}[/tex]

Total distance required for the car to stop is 10+80 = 90 m. So, the car will be able to stop before it reaches the truck.
