55.two objects with different masses are sitting on the same shelf. which object has a higher mechanical energy?

Answers

Answer 1

When two objects with different mass are sitting on the same height ,the object with higher mass has more kinetic energy.

Higher the mass of the object higher the gravitational energy.It is the sum of potential energy and kinetic energy, It is the energy of an object either in motion or the energy that is stored in objects by their position.

          Eg =mgh

     Where ,m=mass

                 g= gravitational field

                 h= height

When an object is lifted it has gravitational potential energy.when it is dropped it begins to lose it,then form kinetic energy.

                Eg (initial) =Ek (final)

So, the object with higher mass has high kinetic energy.

Answers

James Bond should must wait for 6.82 second before jumping in order to safely make it into the car.

The speed of the car of the bad guy is 30m/s.

The speed of the helicopter of James Bond flying is 100m/s. Helicopter is flying at a height of 120m and it is behind 440m of the car.

The speed of the helicopter relative to the car is 70m/s.

So, with the speed James Bond has to jump into the car which is at a depth of 120m and at horizontal distance of 440m.

Assuming that James bond jump directly vertically down into the car.

We can write,

Time taken by the helicopter to cover the distance of 440 meters.

Time = distance/relative speed

Time = 440/70

Time = 6.82 seconds.

if a cannonball were fired horizontally from a cannon atop a very high mountain what would its trajectory look like

Answers

The trajectory of the cannonball will be in parabolic motion.

A trajectory is an object that only gravity acts on. The downward force, gravity, accelerates the projectile downward. The vertical components of motion are independent of each other, so gravity does not change the object's horizontal velocity. A vertical force does not cause horizontal movement. A vertical force acting on a horizontally moving object causes the object to deviate from its linear trajectory.

When an object moving forward is affected by gravity, it falls in a parabolic arc. Since the projectile is an object affected only by gravity, the projectile's path forward from the initial thrust momentum is parabolic.

Answers

The secondary coil of the transformer is 21 turns.

We need to know about transformers to solve this problem. The transformer is a device that changes the output voltage by using different turns on its coil. The ratio of output voltage and input voltage should follow this equation

Vo / Vi = Ns / Np

where Vo is output voltage, Vi is input voltage, Ns is secondary turns and Np is primary turns.

From the question above, the given parameters are

Vi = 80 V

Vo = 9.8 V

Np = 170 turns

By using the equation, we can calculate the secondary turns

Vo / Vi = Ns / Np

80 / 9.8 = 170 / Ns

Ns = 170 . 9.8 / 80

Ns = 20.825

Horror vacui or Nature abhors a vacuum is the principle that explain the inability of wine to pour from the bottom of a barrel without a top opening.

What is Horror vacui ?

In physics, horror vacui, or plenism, is a postulate attributed to Aristotle. He articulated a notion, later questioned by the atomism of Epicurus and Lucretius, that nature contains no vacuums since the denser surrounding material continuum would fill the rarity of an incipient void right away.

He also argued against the void in a more abstract sense, saying, for instance, that since a void is nothing by definition, it cannot be said to exist. This is in line with Plato. Furthermore, because it wouldn't have any features, it couldn't be perceived by the senses and its supposition wouldn't be able to add to the explanation.

A golfer strikes a golf ball at a 35 degree angle with a vertical velocity of 25 m/s. what is the initial resultant velocity of the golf ball the moment it becomes airborn?

Answers

The resultant velocity of the golf ball would be 30.525m/s.

Velocity is a vector quantity so we can deduce velocity components in two form

V = VcosФ + VsinФ

the vertical component is nothing but VcosФ , because it makes 35 degree angle with vertical velocity and the horizontal component is VsinФ.

So according to the question, we can write

25m/s = VcosФ

25m/s = Vcos35

Since cos35 = 0.819, so putting the appropriate values, we get

V = 25/0.819

V = 30.525 m/s

The correct answer is 59 kg

Given-

Mass of bicycle = 10 kg

                      F = 138 N

The mass of any body can be calculated by the force and acceleration of that body. We can use the formula as-

                   m = F/a

                       = 138/2

the 3.0-m-long, 100 kg rigid beam of figure ex12.31 is supported at each end. an 80 kg student stands 2.0 m from support 1. how much upward force does each support exert on the beam?

Answers

The amount of upward force each support exert on the beam is  751.33 N and 1012.67 N.

What is force?

Force can be defined as the product of mass and acceleration of a body.

To calculate the upward force exerted by the beam, we apply the principle of moment.

From the diagram attached,

Taking our moment about N₂,

Mgd₁+mgd₂ = N₂L............ Equation 1

Where:

M = Mass of the beam d₁ = mid point of the beamm = Mass of the studentd₂ = Distance of the student from N₂N₂ = Supporrt 2L = Length of the beamg = Acceleration due to gravity.

From the question,

M = 100 kgm = 80 kgd₁ = 1.5 md₂ = 1 mL = 3 mg = 9.8 m/s²

Substitute these values into equation 1 and solve for N₂

N₂×3 = (100×9.8×1.5)+(80×1×9.8)3N₂ = 1470+7843N₂ = 2254N₂ =  2254/3 N₂ = 751.33 N

To calculate the First support N₁, we use the formula below.

N₁ + N₂ = mg+MgN₁ = mg+Mg-N₂N₁ = (80×9.8)+(100×9.8)-751.33N₁ = 1764-751.33N₁ = 1012.67 N

Let's consider m = 1 (the mass of the cart is not changing so it is constant),

F = 2, and a = 4.

2 = 1 x 4

When doubling force we need to maintain equality so acceleration should double too. To understand it better find the ratio of force and acceleration 2/4 = 1/2. The ratio of force to acceleration should always equal half in all scenarios, this way we can see how equality is maintained.

2x2 = 1 x (4x2)

Amplitude modulation, or AM, is a modulation method used in electronic communication, most frequently for radio wave transmission of messages.

What is amplitude mode?A common collective excitation associated with the spontaneous breaking of a continuous symmetry is the amplitude (Higgs) mode. We use a combination of stochastic analytic continuation and quantum Monte Carlo (QMC) simulations to look at the dynamics of the amplitude mode in a three-dimensional dimerized quantum spin system.In physics, amplitude refers to the most displacement or distance that a point on a vibrating body or wave can travel in relation to its equilibrium location.The method of amplitude modulation involves changing the amplitude of the wave signal before it is broadcast. It is frequently used to send information using a radio carrier wave and is known by the abbreviation AM. Electronic communication is where amplitude modulation is most commonly utilized.

For example, you might write something like: "verbs always match nouns in number, and they usually come before the noun." In other words, make your best guess for the grammar rule that makes sense out of the pattern(s) you see in the phrases you have been working with. Review if you need to, and you might briefly check your hunches against the sentences you have been working with in this or previous modules.
