a mountain 6.0 km from a person exerts a gravitational force on him equal to 2.30% of his weight. calculate the mass of the mountain.

Answer:

hi I don't know sorry sorry forgive me

Explanation:

sorry

it's caused by a pressure that is large on the button of an object that it is on the top of an object submerged in a liquid.

Explanation:

This is why object appear to weigh less when immersed in a liquid. If the upthrust is greater than the weight of the object, the object will rise up through the liquid.

The cyclic frequency of the resulting motion is 1.438 Hz. when  the acceleration due to gravity is 9.8 m/s 2. Because the mass possesses kinetic energy at the static equilibrium displacement, which is translated into potential energy stored in the spring at the extremes of its journey, oscillations happen.

Given:
Force constant of the spring = k
Displacement from equilibrium point = 21.9 cm
Displacement from equilibrium point during oscillation = 8.1 cm
Acceleration due to gravity = 9.8 m/s²Formula used:
The frequency of oscillation is given by the formula f = 1/2π √(k/m)
where k is the force constant of the spring and m is the mass of the object.

In this case, we do not have the mass of the weight, but we can assume that the weight is the only object oscillating, and therefore its mass will be considered as m. If the weight is denoted by w, then its mass will be w/g, where g is the acceleration due to gravity.

Therefore,
m = w/g

Displacement during oscillation = 8.1 cm
= 0.081 m
The maximum extension of the spring from the equilibrium point during the oscillation will be the sum of the equilibrium position and the displacement from the equilibrium point during oscillation, i.e.
y = 21.9 cm + 8.1 cm
= 30 cm
= 0.3 m

Frequency of oscillation f

1/2π √(k/m)
Substituting m = w/g, we get
f = 1/2π √(k/(w/g))
f = 1/2π √(kg/w)
Now we will calculate k.
k = mg/y
where m is the mass of the weight, g is the acceleration due to gravity, and y is the maximum extension of the spring from the equilibrium point during the oscillation.
Substituting values, we get
k = (w/g)(9.8 m/s²)/(0.3 m)
k = 32.67w/g
Substituting this value in the equation for frequency, we get
f = 1/2π √(32.67w/gw)
f = 1/2π √(32.67/g)
f = 1.438 Hz

Therefore, the cyclic frequency of the resulting motion is 1.438 Hz.

The type of energy produced when the handle of a pencil sharpener turns is mechanical energy.

The total of an object's kinetic and potential energy is its mechanical energy. You convert your own chemical energy—obtained through food—into the mechanical energy of a pencil sharpener's handle when you turn the handle.

The pencil is then sharpened using this mechanical energy by spinning the sharpening blades, which grinds away the graphite and wood while generating heat and friction. As the handle warms up from friction, some of the mechanical energy is transferred into thermal energy, and some of it is changed into the kinetic energy of the sharpened pencil as it proceeds through the sharpening process.

The velocity after 2 seconds is 26 m/s. It takes 11.50 seconds to reach a velocity of 40m/s.

Given the equation s(t) = 6t + 5t²

Let's find the velocity after 2 seconds.

(a) Velocity = (ds)/(dt)

Differentiating s(t) with respect to t, we get; ds(t) / dt = 6 + 10t

At t = 2,ds(t) / dt = 6 + 10t = 6 + 10(2) = 26m/s

Therefore, the velocity after 2 seconds is 26 m/s.

(b) We are to find how long it takes for the velocity to reach 40m/s. We know that the initial velocity of the ball, u = 6m/s. Acceleration = gsinθ = 9.81 x sin (angle of inclination) = 9.81 x 0.3 = 2.943 m/s²From the first equation of motion, v = u + at

We know v = 40m/s, u = 6m/s, a = 2.943m/s² and t is what we are to find, hence the equation becomes;40 = 6 + 2.943(t)t = (40 - 6) / 2.943t = 11.50s

Therefore, it takes 11.50 seconds to reach a velocity of 40m/s.

In conclusion, it would require approximately 441000π Nm of work to pump all the water out of the tank.

To calculate the work required to pump all the water out of the tank, we need to consider the volume of the water and the force needed to lift it.
First, let's find the volume of the water in the tank. The tank is shaped like a cone with a height of 7 meters and a base radius of 3 meters. The volume of a cone can be calculated using the formula

V = (1/3) * π * r^2 * h,

where r is the radius and h is the height. Plugging in the values, we get

V = (1/3) * π * 3^2 * 7 = 63π cubic meters.
Since the density of water is given as 10000 N/m^3, the weight of the water in the tank is equal to the volume multiplied by the density, which is

63π * 10000 = 63000π N.
To find the work required to pump out the water, we need to calculate the force needed to lift it. The force required to lift an object is equal to its weight, which in this case is 63000π N.
Work is calculated by multiplying the force applied to an object by the distance over which the force is applied. In this case, the force is applied to lift the water from the bottom of the tank to the top, which is a distance of 7 meters.
Therefore, the work required to pump all the water out of the tank is equal to the force multiplied by the distance, which is

63000π * 7 = 441000π Nm.
In conclusion, it would require approximately 441000π Nm of work to pump all the water out of the tank.

The answer is below

Explanation:

A 140 kg load is attached to a crane, which moves the load vertically. Calculate the tension in the

cable for the following cases:

a. The load moves downward at a constant velocity

b. The load accelerates downward at a rate 0.4 m/s??

C. The load accelerates upward at a rate 0.4 m/s??

Solution:

Acceleration due to gravity (g) = 10 m/s²

a) Given that the mass of the crane (m) is 140 kg. If the load moves downward, the tension (T) is given by:

mg - T = ma

Since the load has a constant velocity, hence acceleration (a) = 0. Therefore:

mg - T = m(0)

mg - T = 0

T = mg

T = 140(10) = 1400 N

T = 1400 N

b)  If the load moves downward, the tension (T) is given by:

mg - T = ma

T = mg - ma = m(g - a)

T = 140(10 - 0.4) = 140(9.96) = 134.4

T = 134.4 N

c)  If the load moves upward, the tension (T) is given by:

T - mg = ma

T = ma + mg = m(a + g)

T = 140(0.4 + 10) = 140(10.4)

T = 145.6 N

2) To find the distance (s) if the load move from rest (u= 0) and accelerates for 20 seconds (t = 20). We use:

s = ut + (1/2)gt²

s = 0(20) + (1/2)(10)(20)²

s = 2000 m

The red car is observed to experience less centripetal acceleration when compared to the blue car.

The red circle is a circular path which is said to be the outer lane.

The blue car is said to be in the inner lane which has less radius than the red circle.

They both are said to be moving with the same speed.

A body moving in the circular path is said to be moving with centripetal acceleration. The direction of that body keeps changing constantly and so its velocity hence producing acceleration.

It is given by the expression, ac = v²/r

where, ac is centripetal acceleration

v is velocity

r is distance from centre of circle to the moving body

From the above equation, it is clear that centripetal acceleration is inversely proportional to the distance from centre of circle to the moving body.

As the red circle is said to be the outer lane, it has a greater r value compared to blue car and so, less centripetal acceleration.

The conduction of current on the postsynaptic neuron in an electrical synapse occurs through direct flow of ions between the presynaptic and postsynaptic neurons.

In electrical synapses, the conduction of current on the postsynaptic neuron occurs through direct flow of ions between the presynaptic and postsynaptic neurons. These synapses are formed by specialized structures called gap junctions, which create channels between the cells, allowing ions to pass through. The channels are formed by connexin proteins that span the plasma membranes of adjacent neurons.

When an action potential reaches the presynaptic neuron, it depolarizes the cell membrane and triggers the opening of voltage-gated ion channels. This results in the influx of positively charged ions, such as sodium (Na+), into the presynaptic neuron. As a result, the electrical potential of the presynaptic neuron becomes more positive.

Due to the direct connection provided by the gap junctions, these positive ions can flow through the channels into the postsynaptic neuron. This movement of ions generates an electrical current that spreads across the postsynaptic neuron. The current causes depolarization of the postsynaptic membrane, leading to the initiation of an action potential in the postsynaptic neuron.

The strength of the electrical synapse is determined by the size of the gap junctions and the number of connexin proteins present. The larger the gap junctions and the more connexin proteins, the more ions can pass through, resulting in a stronger electrical coupling between the neurons.

at electrical synapses, the conduction of current on the postsynaptic neuron occurs through the direct flow of ions between the presynaptic and postsynaptic neurons via specialized gap junctions. This direct electrical coupling allows for rapid and synchronized transmission of signals. Electrical synapses are particularly important in neural circuits that require fast and coordinated communication, such as in reflex arcs or the synchronization of cardiac muscle cells.
