Given Data :

▪ Initial velocity = zero ( body is at rest)

▪ Distance travelled = 100m

▪ Final kinetic energy = 200000J

To Find :

▪ Resultant force acting on the car.

Therefore:

W = F × d = ΔK ----------------- eq 1.

where,

W = work done

F = applied force

d = distance

ΔK = change in kinetic energy

Calculation :

→ F × d = Kf - Ki ----------------- eq 2.

Where:

Kf = Final kinetic energy = 200000

Ki = initial kinetic energy = 0

Substituting our values into the formula from equation (2)

→ F × 100 = 200000 - 0

→ F = 200000/100

→ F = 2000N

From the analysis, it can be concluded that planet A has the strongest gravitational field, followed by planet C, and planets B and D have the same gravitational field strength.

The gravitational force acting on various masses is measured on different planets. The table shows the measured values for the forces acting on the corresponding masses:Planet Force (N) Mass (kg)A 8.0 0.50B 30 3.0C 45 3.0D 60 6.0

Method for comparing the gravitational field strengths on the different planets:First, we can use the formula for calculating gravitational force: \(`F = G (m_1m_2 / r^2)`\)where G is the universal gravitational constant `\(6.67 * 10^{-11 }Nm^2/kg^2\), m1 and m2 are the masses of the two objects in kg, and r is the distance between the centers of the objects in meters.

We know that the force is proportional to mass (F = ma). So we can calculate the acceleration due to gravity (g) on each planet by dividing the force by the mass. Therefore, we can use the formula: `g = F / m`.

Comparing the gravitational field strengths on the different planets:We will calculate the acceleration due to gravity (g) on each planet.

For planet A: `

g = F / m

= 8.0 N / 0.50 kg

= 16 \(m/s^2\)`

For planet B: `g = F / m

= 30 N / 3.0 kg

= 10 \(m/s^2\)

For planet C: `g = F / m

= 45 N / 3.0 kg

= 15 \(m/s^2\)

For planet D: `g = F / m

= 60 N / 6.0 kg

= 10 \(m/s^2\)

`So we see that planet A has the strongest gravitational field, followed by planet C, then planet B and planet D have the same gravitational field strength.

Answer:

rotation is a day and revolution is 365 days

The answer to the question is that option C is the correct answer: the statement stands incorrect. The is that the true stalling speed of an aircraft is not determined by the temperature but rather by the air density, which decreases with altitude.

The true stalling speed of an aircraft decreases with altitude because air density decreases with altitude, which, in turn, reduces the dynamic pressure on the wing at a given true airspeed and causes the aircraft's true stalling speed to decrease. Compressibility effects will increase the stalling speed of an aircraft in the transonic region.

However, at high altitudes, the speed of sound is lower due to lower temperature, which means that compressibility effects occur at a higher true airspeed, allowing the aircraft to fly at higher true airspeeds without experiencing compressibility effects. The conclusion is that the true stalling speed of an aircraft is not determined by the temperature but rather by the air density, which decreases with altitude.

A negative magnetic field reading indicates the magnetic field is in the opposite direction of the reference direction, while recording the absolute value removes the sign, focusing on the field's strength.

When using a physical probe to measure magnetic fields, a negative reading signifies that the direction of the magnetic field is opposite to the reference direction chosen. This occurs due to the nature of magnetic fields, which have both magnitude and direction. The procedure asks you to record the absolute value of the magnetic field because it is often more important to know the field's strength rather than its direction.

The absolute value eliminates the negative sign, providing a measure of the magnetic field's magnitude, regardless of its direction. This allows for better comparison and analysis of the magnetic field's strength in different locations or under various conditions, making it a more meaningful metric in many cases.

False. The formula for net filtration pressure (NFP) is calculated as the difference between the hydrostatic pressure (HP) and the colloid osmotic pressure (OP) across the capillary walls. The formula for NFP is:

NFP = HP - OP

HP represents the hydrostatic pressure exerted by the fluid within the capillaries, while OP represents the osmotic pressure exerted by the proteins and solutes in the blood. The sum of HP and OP gives the forces acting in opposite directions, determining the movement of fluid across the capillary walls.

A body moves in a perfectly circular path at constant speed. There must be a force pulling toward the center of the circle. According to Newton's first law, there must a force present to keep the object moving in a circle rather than a straight line.

Newton's 1st law is to show the resultant force acting on an object with a composition equal to zero, so that an object that is initially at rest will always remain at rest. While an object initially moves in a straight line, it will forever continue to move in a straight line at a constant speed. So it can be concluded that in Newton's Law 1 the acceleration of an object is directly proportional to the force acting on the object and inversely proportional to the mass or weight of the object itself.

The properties of objects in Newton's 1st law tend to maintain their original state with the same inertia or degree of inertia. That is why Newton's 1st Law is also known as the Law of Inertia. The shape of the moment of inertia in Newton's 1st Law occurs in various forms, for example linear moments of inertia, mass moments of inertia, and polar or polar moments of inertia.

The magnitude of the stresses also differ according to the material used, such as bending stress and torsional stress, so the calculation can be based on the moment of inertia

Newton's third law of motion states that for every action, there is an equal and opposite reaction. The action-reaction pair is used to describe the interaction between two objects. Therefore, when a car is speeding up as it drives along a level road, an action-reaction pair occurs.

An action-reaction pair is a pair of forces that are equal in strength and opposite in direction. When an object exerts a force on another object, the second object exerts an equal and opposite force on the first object. The action-reaction pair when a car speeds up as it drives along a level road can be explained as follows: Action force: The car exerts a force on the road in the forward direction. This is the action force. Reaction force: The road exerts a force on the car in the backward direction. This is the reaction force.

To estimate the speed of a singly ionized uranium ion (238U+) needed to circle the Earth 5.0 km above the equator, we can use the concept of magnetic force experienced by a charged particle moving in a magnetic field.

The magnetic force on a charged particle moving in a magnetic field is given by the equation F = q * v * B, where F is the magnetic force, q is the charge of the particle, v is its velocity, and B is the magnetic field.

In this case, the uranium ion has a charge of e (the elementary charge) and is moving in the Earth's magnetic field with a magnitude of 0.50 x \(10^-^4\)T.

The magnetic force provides the necessary centripetal force to keep the uranium ion in a circular path around the Earth. Therefore, we can equate the magnetic force to the centripetal force, which is given by the equation F = m * \((v^2 / r)\), where m is the mass of the uranium ion and r is the radius of the circular path.

Equating these two forces, we have q * v * B = m *\((v^2 / r).\)

Simplifying and solving for v, we find v = \((q * r * B / m)^0^.^5\).

Substituting the known values, where q = e, r = radius of the Earth + 5.0 km, B = 0.50 x \(10^-^4\) T, and m = mass of uranium ion, we can calculate the speed.

To a Zerkonian observer, the lights on your starship do not flash simultaneously. The trailing light flashes first.

This is due to the phenomenon of time dilation, predicted by Einstein's theory of relativity. As you, the observer on the starship, are moving away from the planet Zerkon at a high velocity of 0.70c (70% of the speed of light), time appears to be passing slower for you relative to the stationary frame of reference on Zerkon. As a result, the time interval between the flashes of the warning lights, which is one minute in your frame of reference, will be dilated or stretched from the perspective of the Zerkonian observer. The light at the front of your starship, which is moving away from Zerkon, takes longer to reach the observer compared to the light at the trailing end. Therefore, the trailing light will be observed to flash first by the Zerkonian observer. Hence, the correct answer is C. The trailing light flashes first.

The heating curve could be describing processes such as boiling and endothermic reactions.A heating curve is a graphical representation that shows the changes in temperature as a substance is heated.

It typically consists of two distinct segments: heating and phase change. Boiling is a process where a substance changes from its liquid phase to its gaseous phase. During the heating phase, the temperature of the substance gradually increases until it reaches its boiling point. At this point, the substance undergoes a phase change, and the temperature remains constant until all the liquid has vaporized. Therefore, the heating curve could be describing the process of boiling.

Endothermic reactions are chemical reactions that absorb heat from their surroundings, resulting in a decrease in temperature. If the heating curve represents the temperature changes during an endothermic reaction, we would observe a decrease or plateau in temperature during the reaction, followed by a subsequent increase. Thus, the heating curve could also be describing an endothermic reaction.

Condensation, on the other hand, is the process by which a substance changes from its gaseous phase to its liquid phase. It typically occurs when a gas is cooled down, and the temperature decreases. However, the heating curve represents temperature changes during the heating process, not cooling. Therefore, condensation is not applicable to the heating curve.
