Three masses are arranged in the (x, y) plane
as shown.

What is the magnitude of the resulting
force on the 2 kg mass at the origin? The
value of the universal gravitational constant
is 6.6726 × 10−11 N · m2
/kg2
.
Answer in units of N.

The energy transferred as work is 550 J and the change in internal energy is 997.68 J

The work done is same as to the area under curve as shown.

W = (1.6-1.4)x10-3](55.0x105)+ -(60-55.0)x105 (1.6-1.4)x10-3

work done= 550 J

The change in internal energy is,

ΔU = nc(T2 -TI,)

=n5/2R (T2-TI])

=(3 mole) (8.314 J/mol.K) (353-337)5/2 K

=997.68 J

Putting energy into an object to cause some displacement is what is meant by the definition of work. To be able to work done is to have energy. Always the same work is completed. Potential and kinetic energy are just two examples of the various types of energy. For an object to move, energy must be transferred to it. Force is one possible way to transfer energy. Work is the term used to describe the energy expended when a force is used to move an object.

3. Both of the above. The normal force can provide the same amount of work as the gravitational force, since it is the force that is perpendicular to the surface and prevents the jumper from going through it. The normal force can also oppose the motion of the jumper, if the jumper is trying to go too fast and is pushing against the surface.

In many situations in life, we rely on the normal force to keep us safe. For example, when we jump off a cliff into a pool of water, the normal force is what prevents us from going through the surface of the water and hitting the bottom of the pool. Without the normal force, we would simply fall through the water and possibly hurt ourselves.

The normal force is also important in other situations. For example, when we are driving in a car and hit a bump in the road, the normal force is what keeps us from being thrown out of our seats. Without the normal force, we would simply be thrown around inside the car and possibly injured.

So, as you can see, the normal force is important in many different situations. It is a force that we often take for granted, but which plays a vital role in keeping us safe.

As you approach a steady light source, the wavelength of the emitted light appears shorter.

The distance over which a periodic wave's shape repeats is known as its wavelength. It is a property of both traveling waves and standing waves, as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two neighboring crests, troughs, or zero crossings. The spatial frequency is the reciprocal of the wavelength. The Greek letter lambda () is frequently used to denote wavelength. The term wavelength is also sometimes used to describe modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.

Wavelength and frequency are inversely related for a sinusoidal wave traveling at a constant speed.

The force exerted by the roller coaster car on the loop's track at this position is 46600 N, also known as the upward force. Upward force is affected by net force and downward force. And downward force is affected by the gravity of the earth.

To calculate the upward force, we will use Newton's second rule of motion:

F=m·a

The following is how the upward force calculated:

Known variables:

m = 2000 kg

v = 18 m/s

r = 24 m

g = 9.8 m/s²

First, we need to find the roller coaster cas acceleration:

a = v²/r

a = (18.0m/s)²/(24.0)

a = 13.5m/s²

Net force (Fnet), as we mentioned above, is affected by the upward (F₀) and downward force (F₁) in the equation:

Fnet = F₀ - F₁

Net force is the mass of the roller coaster multiplied by its acceleration:

Fnet = m·a

Fnet = (2000kg)·(13.5m/s)

Fnet = 27000 N

Downward force (F₁) is affected by the gravity of the earth:

F₁ = m·g

F₁ = (2000kg) · (9.8m/s²)

F₁ = 19600 N

Therefore, the upward force (F₀) can be calculated using the equation:

F₀ = F(net) + F₁

F₀ = 27000N + 19600N

F₀ = 46600 N

As a result, the upward force that a 2000 kg roller coaster exerted with 18 m/s speed at 24 m radius loop is 46600 Newton

The new force is 1/9 times of the original gravitational force

The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface. synonyms for gravity include gravitation and gravitational attraction.

The term gravitational force refers to the force that the earth exerts on a body. Examples of motion caused by gravitational force include the downward motion of water in a river, the downward motion of water in a stream, and the upward motion of a ball when it is thrown.

Let F’ be the force, when the distance between the two is tripled

therefore:

the “tripled ” acts on both the “3” and the “r” leaving 4r^3

Distance and gravitational force have an inverse square relationship.

F’ = F/9

The value of the objects maximum speed is 52.02 cm/s.

The velocity is greatest at y=0, when displacement and acceleration are both equal to zero. This means that the system is in equilibrium. Hence, at a particular point in simple harmonic motion, the maximum value of the object's speed can be calculated by using the equation,

v = A ω

Here,

v = Maximum velocity

A = Amplitude

ω = Angular frequency

The rate at which the waveform phase changes or the angular displacement of any wave element per unit of time is referred to as the angular frequency. Symbol of angular frequency is ω.

Given,

Mass of the object (m) = 0.440 kg

Force constant (K) = 8.00 n/m

Amplitude (A) = 12.2 cm

Now,

v = A ω

We know ω = √k/m

Now substituting we get,

v = A√k/m

Putting the values in the above equation, we get

v = 12.2 × √(8/0.44)

  = 52.02 cm/s

Hence, the maximum speed is 52.02 cm/s.
