A car accelerates from 20m/s to40 m/s in 10sec. what is the distance traveled by the car during the 4th second.
Answer:
Distance traveled by the car during the 4th second is 120 meters.
If this help please set brainliest.
Explanation:
To find the distance traveled by the car during the 4th second, you need to know the acceleration of the car. The acceleration is the change in velocity (in this case, the change in speed) over time. Since the car's speed increased from 20 m/s to 40 m/s in 10 seconds, the acceleration is (40-20)/10 = 2 m/s^2.
To find the distance traveled during the 4th second, you can use the formula d = vt, where d is the distance traveled, v is the velocity (in this case, the average velocity during the 4th second), and t is the time traveled (in this case, 4 seconds).
The average velocity during the 4th second is simply the average of the initial and final velocities, which is (20+40)/2 = 30 m/s. Plugging this value into the formula, we get d = 30 m/s * 4 s = 120 meters. Therefore, the distance traveled by the car during the 4th second is 120 meters.
Given,
u=8 m/s
v=16 m/s
t=10 sec
(i) using equation
a= v-u/t
= (16-8)
= 8/10
= 0.8 / ms^2
= acceleration
(ii) Displacement
S = ut + 1/2 at^2
= 8×10+1/2×0.8× (10)^2
= 80 + 0.4 × 100
= ( 80 + 40) m
S = 120 m
n1 moles of a monatomic gas and n2 moles of a diatomic gas are mixed together in a container.
Part A
What is an expression for the molar specific heat at constant volume of the mixture.
Express your answer in terms of the given quantities and appropriate constants.
Part B
Show that your expression has the expected behavior if n1?0 or n2?0.
Express your answer in terms of the given quantities and appropriate constants. Enter your answers numerically separated by a comma.
Part A: The molar specific heat at constant volume for a mixture of gases can be calculated using the formula:
Cv,mixture = (n1Cv,monatomic + n2Cv,diatomic) / (n1 + n2)
where Cv, monatomic, and Cv, diatomic are the molar-specific heats at constant volume for the monatomic and diatomic gases, respectively.
Part B: If n1 = 0, the expression simplifies to Cv,
mixture = (0Cv,monatomic + n2Cv,diatomic) / n2 = Cv,diatomic. Similarly, if n2 = 0, the expression simplifies to Cv,mixture = (n1Cv,monatomic + 0Cv,diatomic) / n1 = Cv,monatomic.
This shows that the expression behaves as expected by approaching the molar-specific heat at the constant volume of one of the gases as the number of moles of the other gas approaches zero.

A box is 2.00 m wide, 3.00 m long, and 0.200 m deep. The box has a mass of 1400 kg. Once the
box is placed in a container of water, it sinks. Calculate the apparent weight of the box when it is
submerged in water. The density of water is 1000 kg/m³.
O 2657 N
O 2264 N
O 1962 N
O 1659 N
Answer:
2264 N
Explanation:
Because the apparent weight of an object when it is submerged in water is equal to its actual weight minus the weight of the volume of water that it displaces.
The weight of the object is 1400 kg x 9.81 m/s² = 13 774 N.
The volume of the box is 2.00 m x 3.00 m x 0.200 m = 1.20 m³
The weight of the water displaced is 1.20 m³ x 1000 kg/m³ x 9.81 m/s² = 11 510 N
Therefore, the apparent weight of the box when submerged in water is 13 774 N - 11 510 N = 2264 N.

Free body motion with force and friction describes in Newton's second law
Newton's second law.When a body is in motion with a force and friction, the motion of the body is described by Newton's second law, which states that the acceleration of an object is dependent on the net force applied to it and the mass of the object.
This means that the motion of the body is determined by the sum of all forces acting on it.
This includes both the force applied to the body, as well as the friction forces opposing it. In order for the body to remain in motion, the force applied must be greater than the friction forces acting against it.

Two uniformly charged pellets A and B are held some distance from each other, andthen the charge on A is doubled.Which of the following statements is most correct?A.The magnitude of the electric force exerted on A is doubled because the electric field atthe position of A is doubled.B.The magnitude of the electric force exerted on B is doubled because the electric field atthe position of B is doubled.C.The magnitude of the electric force exerted on A is doubled because the electric field atthe position of B is doubled.D.The magnitude of the electric force exerted on B is doubled because the electric field atthe position of A is doubled
The correct statement is D. The magnitude of the electric force exerted on B is doubled because the electric field at the position of A is doubled.
When two charged particles, such as A and B, are held some distance apart, they exert an electric force on each other due to their charges. The strength of this force is determined by the amount of charge on each particle and the distance between them. This force is called Coulomb force and it follows the Coulomb's law. The Coulomb's law states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
When the charge on A is doubled, the electric field at the position of A increases, and as a result, the force exerted on B also increases. This is because the electric field at the position of A is what causes the force on B. The magnitude of the electric force on B is proportional to the product of the charges of A and B, and inversely proportional to the square of the distance between them. So as the charge on A doubles, the force on B also doubles.

Applying the momentum principle, v = 0.08 m/s.
The Momentum Principle controls how a system moves. This theory explains how a system modifies its motion in response to a net force. We note that there is no net force acting on objects moving in a straight path at constant speed.
p = m v . The equation demonstrates that momentum is directly related to an object's mass (m) and velocity (v). As a result, an object's momentum increases with increasing mass or velocity. The momentum of a large, swift object is larger than that of a small, slower object.

Momentum: Project egg drop
I need a project report for an egg drop (high school level) for my class.
Answer: okay thx
Explanation:
It's all about Inertia! Inertia says an object, the egg in this case, will stay at rest, unless an outside force acts upon it, your hand in this case. When you move the pie pan with your hand, gravity pulls the egg straight into the glass of water.
Check Writing QualityThe Egg-Drop Device Process The process of dropping an egg is more complex than an average person would believe. The egg-dropping process requires knowledge of history, engineering, mathematics, and physics. To fully understand how an egg drops, the ability of the history of physics, the engineering behind a device, and the mathematics and physics of free-fall are needed.
Physics originates in its classical form in Ancient Greece. Thales was the first physicist. The theories Thales made gave the discipline of physics its name. Thales believes that the world, although made of many materials, was made of only one element: water. The interaction of water between the phases of solid, liquid, and gas gives materials different properties.
Copernicus discovers that the Sun was the center of the solar system, not the Earth. Kepler develops the three laws of planetary motion. Galileo discovers that the natural state of an object is either at rest or moving with a constant speed, for as long as no unbalanced forces are acting on the object. Galileo reasons that if friction and other forces were balanced, an object would continue along at constant speed.
The conceptual side of egg-dropping requires knowledge of free-fall physics. The most basic formula to know is v = d/t, or velocity is equal to the distance divided by the elapsed time. In the test simulation, the device is dropped at a distance of 75 feet or 22.86 meters, and the average elapsed time is 2.223 seconds. Using these two values, substituted into the formula, the velocity is determined to be 10.2834 meters per second. Velocity is a vector quantity with direction and magnitude. In the case of the device, the direction is directly down or 90 degrees below the horizontal and the magnitude is 10.2834. After solving for velocity, one can get the acceleration of the device as it drops from 75 feet. To calculate acceleration, the formula a = v / t, or in other words, acceleration is equal to velocity divided by the elapsed time.
The Egg Drop project is a highly-versatile activity that can be used to introduce students to physics, materials science, and fluid dynamics. For elementary and middle school classes, the students have a wide range of materials to 'buy' with their allotted budgets.
Answer: 1. Make a triangle out of a straw and tape it together.
2. Repeat this two more times.
3. Tape all 3 triangles together around the egg to make a pyramid shape.
4. Decide how else to cushion the egg - for example: using more straws.
5. Spread the painter's tarp on the floor.
A TV requires a potential difference of 11.5V and a current of 10A. It uses a transformer to produce the
correct potential difference from the mains supply. If the mains supply is 230, what current does it
provide to the transformer?
Answer:
1800W
Explanation:
A TV requires a potential difference of 11.5V and a current of 10A. It uses a transformer to produce the correct potential difference from the mains supply. If the mains supply is 230V, what current does it provide to the transformer? The required electrical power output of a step-up transformer is 1800W.
