what’s the moment if there’s a force of 50n and 0.75cm

The amount of work required to climb steps or to remain motionless while mounting a moving escalator is the same in both situations, however in the first case, the effort is in pushing the body upward, whereas in the second, it is in pushing the escalator downward.

In physics, the term "work" refers to the measurement of energy transfer that takes place when an item is moved over a distance by an external force, at least a portion of which is applied in the direction of the displacement.

The length of the path is multiplied by the component of the force acting along the path to calculate work if the force is constant. The work W is theoretically equivalent to the force f times the distance d, or W = fd, to represent this idea. Work is done when a force is applied at an angleα of to a displacement, or W = fd cosα.

The number of stairs Sara must climb to cancel out the calories consumed is 11667 stairs

To obtain the number of stairs Sara much climb, we'll begin by obtained the total height. This can be obtained as follow:

E = mgh

946671.84 = 69 × 9.8 × h

946671.84 = 676.2 × h

Divide both sides by 676.2

h = 946671.84 / 676.2

h = 1399.99 m

Finally, we shall determine the number of stairs. Details below:

Number of stairs = Total height / height of one stair

Number of stairs = 139999 / 12

Number of stairs = 11667 stairs

The braking force that caused the car to skid to a stop is given by the equation:

Force = mass * acceleration

Plugging in the values for the mass of the car (2400 kg) and its acceleration (-7 m/s/s), we get:

Force = 2400 kg * (-7 m/s/s)

The Moon could never entirely cover the solar disk if it were any smaller or orbited the Earth any further away. If the Moon were a little bit bigger or orbited the Earth a little bit closer, it would cover much of the sun's corona during totality, making eclipses far less impressive. One orbit of the moon around the Earth is completed in around one month.

There would be at least two eclipses per month if the moon orbited in the same plane as the ecliptic, the Earth's orbital plane.

The strength of the magnetic force is inversely proportional to the square of distance between the magnets. Thus, as the distance increases, force between the magnets decreases.

Magnetic force, is the force generated by magnetic flux lines arised from a magnetic field.  A magnet have a south pole and north pole. There will be repulsive force between two like poles and attractive force between two unlike pole.

The force between two objects is always in inverse proportion with the distance and this is well explained by Coulomb's law of forces.

Thus, F ∝ 1/r² where, r is the distance.

Therefore, as the distance between two magnets increases the magnetic force between them decreases.

The roller coaster slows down as it ascends yet another hill. Potential energy is created from kinetic energy.

The energy that an item has due to its height is called gravitational potential energy (PE = mgh), and it is equal to the mass of the object times its height times the gravitational constant. On a roller coaster, the gravitational potential energy is greatest at the top and lowest at the bottom. As the roller coaster speeds down the hill, the potential energy it had while on a slope is transformed into kinetic energy. The roller coaster slows down as it ascends yet another hill. Potential energy is created from kinetic energy.

The roller coaster is propelled by the conversion of potential energy to kinetic energy, and after it has descended the first hill, it has all the kinetic energy it will require for the trip.

Answer: To determine the acceleration of an object in response to a net force, you can use the equation a = F/m, where a is the acceleration, F is the net force, and m is the mass of the object. In your case, the net force is 2.5 N and the mass of the object is 16.2 g. Since the units of force are in newtons and the units of mass are in grams, you will need to convert the mass to kilograms before plugging the values into the equation.

One kilogram is equal to 1000 grams, so 16.2 grams is equal to 0.0162 kilograms. Plugging this value into the equation, we get:

a = F/m

a = 2.5 N / 0.0162 kg

a = 154.32 m/s^2

Thus, the acceleration of the object in response to the net force of 2.5 N is 154.32 m/s^2.
