If 16,700 J of work is done to shoot the human cannonball down a 3.05 m barrel, then how much force is applied to the person to fire them out the cannon?

Answers

Answer 1

Answer:

[tex]5,480\:\text{N}[/tex]

Explanation:

The formula for work is given by [tex]W=F\Delta x[/tex], where [tex]F[/tex] is the force applied over a distance of [tex]\Delta x[/tex].

Plugging in given values, we get:

[tex]16,700=F\cdot 3.05,\\F=\frac{16,700}{3.05},\\F\approx \boxed{5,480\:\text{N}}[/tex](three significant figures).

Option B is the correct answer.

Graphite has a layered structure, every layered structure has rings which consists of six carbon atom.

What is Graphite and what are its characteristics?

   Graphite can be also known as black lead. As it can be structured with hexagonal shape it was also made as octahedral and tetrahedral which is known to be as diamond. Graphite is formed by carbonaceous compound, which can be solidified as magmatic carbon. Graphite can be taken from several ancient rocks, marbles, quartzite, under the soil, etc..  The graphite can be found easily by seeing the honeycomb shape, hexagonal structure, a molecule with six carbon atoms. These were also used in pencil leads, batteries, nuclear reactors, polishes, etc..

Maisey is running 12mph and comes to an abrupt stop in 3 seconds when she hears her name called. What is her acceleration?

Answers

Answer:

~ 0.001 m/s^2

Explanation:

If you convert 12 miles per hour to, miles per second, it makes this easier to calculate, so do that first

12m/ 1 hour * 1 hour/ 60 mins * 1 min/ 60 sec = ~0.003333 miles per second.

Next remember that acceleration = velocity/time

So our new velocity: 0.003333 over time: 3 seconds = the acceleration.

What is a solar eclipse?

When the Moon passes in front of the Sun, blocking all or part of Earth's view of it, a solar eclipse occurs. The Moon is closest to the plane of the Earth's orbit when there is a new moon and such an alignment. During a total eclipse, the Moon fully obscures the Sun's disk. Partial and annular eclipses only block out a section of the Sun. A solar eclipse occurs naturally. Solar eclipses were sometimes linked to supernatural sources or interpreted as an ill omen in several ancient and modern societies.

During a solar eclipse, the moon comes in between the earth and the sun therefore the shadow moves across the sun during a solar eclipse observed by the student, the position is Sun, moon, and earth.

The Escape speed at the surface of a certain planet is twice that of the earth. The planet has a radius twice of the Earth. what is its mass in unit of earth's mass is to be determined.

Explain What is electrical energy and why do we need this energy

Answers

Answer:

WHAT IS ELECTRICAL ENERGY?

Electrical energy is the most convenient form of energy for most human uses. Electrical energy is easy use and move from one location to another, but it is almost impossible to store in any large quantity. It can be used for running computers and most appliances, home heating, and even transportation.

ELECTRICITY is used by industry, households, and businesses—accounting for 18% of end use energy worldwide.

Electrical energy is very convenient, and as a result more and more of the energy used by a high energy society is in the form of electricity, see figure 1. The rate of electrical energy use is growing faster than the rate of electricity use, see figure 2.

WHY DO WE NEED ELECTRICAL ENERGY?

Electrical energy is used throughout the world to power devices, appliances and methods of transportation utilized in daily life. To make things operate, electrical energy must be emitted from energy sources such as power plants, to enable an object to consume the power it needs to function.

Consider a gate whose Shape is a parabolic arch of height 3m and base width 3m. If the origin of the coordinate system is at the vertex, then what is the equation of the edge of the gate?​

Answers

Answer:

An arch in a memorial park, having a parabolic shape, has a height of 25 feet and a base width of 30 feet.

The equation of the parabolic arch with the height of 3m and base width of 3m is x²= 3/16 y.

What is parabolic equation?

Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. An essential component of a conic section is a parabola.

A parabola is formed by cutting a right circular cone in half along a plane perpendicular to the cone's generator. It is a locus of a moving point whose separation from the focus is equal to its separation from a stationary line (directrix) Focus refers to the fixed point, and directrix refers to the fixed line.

The equation of a parabola is x² = 4ay.

Height of the arch = 3 m

base width = 3 m

thus it goes through the point (3/2, 3)

then, (3/2)²  = 4 a 3

a =  9 / (4× 12) = 3 /16

Then the equation of the parabolic arch becomes  x² = 3/16 y.

Answers

Answer: A. An ice hockey player picks up a trophy as he slides past it

Explanation:

A PE X

The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

What is collision?

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

What is elastic collision

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

What is inelastic collision ?

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

What is perfectly inelastic collision?

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

What is coefficient of restitution ?

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.

220÷0.02=11000 kg/m

A wooden post has a volume of 0.025 and a mass of 20kg. Calculate its density in kg/m.

Explanation: Took the exam

The arrows in this photograph represent: An action-reaction force pair. Hence, option (B) is correct.

What is  action-reaction force pair?

When two bodies interact, they exert an equal and opposite force on one another in accordance with Newton's third law of motion. Action-reaction forces are made up of these forces.

"When one body exerts a force on the other body, the first body experiences a force that is equal in magnitude in the opposite direction of the force which is exerted," according to Newton's third law of motion.

According to the above assertion, there are always two forces operating on the objects involved in an interaction. The forces are of identical magnitude, but the direction of the force acting on the first object is different from the direction acting on the second.
