How large is the acceleration of a 35-kg mass that has a net force of 270 n applied to it horizontally?.

Answers

If a net force of 270 N applied on a 35-kg mass, the acceleration is 7.7 m/s²

The problem can be solved by applying the Newton's 2nd law of motion, which states: the acceleration on an object is directly proportional to the net force applied to it and inversely proportional to its mass.

F = ma

Where:

F = net force acted on the object

m = mass

a = acceleration

Parameters given in the problem:

m = 35 kg

F = 270 N

Plug these parameters into the formula:

270 = 35 x a

an electron travels through space and has a velocity uncertainty of 131 m/s. what is the minimum uncertainty in the electron's position?

Answers

The minimum uncertainty in the electron's position is equal to the velocity uncertainty divided by the speed of light, which is 131 m/s / 299,792,458 m/s ≈ 4.37 × 10^−9 m.

The minimum uncertainty in the electron's position is determined by the Heisenberg Uncertainty Principle, which states that the product of the uncertainties in position and momentum have to be greater than or equal to a constant, which is equal to Planck's constant (h) divided by 4π.

Therefore, the minimum uncertainty in the electron's position (Δx) can be calculated using the equation below:

Δx * Δp ≥ h/4π

Where Δp is the uncertainty in the electron's momentum, which is equal to the electron's velocity uncertainty (Δv) multiplied by the electron's mass (m):

Δp = Δv * m

Inserting this into the equation for the minimum uncertainty in position, we get:

Δx * Δv*m ≥ h/4π

Simplifying and rearranging this equation, we get:

Δx ≥ h/4π * (1/m*Δv)

For a single electron with a mass of 9.11 x 10-31 kg and velocity uncertainty of 131 m/s, the minimum uncertainty in its position is 1.11 x 10.

a constant force is exerted for a short time interval on a cart that is initially at rest on an air track. this force gives the cart a certain final speed. suppose we repeat the experiment but, instead of starting from rest, the cart is already moving with constant speed in the direction of the force at the moment we begin to apply the force. after we exert the same constant force for the same short time interval, the increase in the cart’s speed

Answers

The cart's increased speed is the same as when it first took off.

Rate is the speed from which an object travels along a path over time, whereas velocity is the speed and orientation of an item's motion.

At first, the cart is at rest.

So, u = 0 m/s.

A brief period of time is spent with a constant force applied.

The final speed that the force gives the cart is what we'll call v.

Newton's first equation of motion yields the following results:

v = u + at

Where;

The ultimate speed =v.

The starting speed =u.

Acceleration = a.

Time = t

u = 0 m/s, therefore we now have;

v = 0 + at

v = at

Let's now use Newton's second rule of motion to construct a formula to introduce force;

F = ma

Where;

Force = f.

Mass = m.

Acceleration = a.

So,

= a = F/m.

Substituting in v = at,

= v = (F/m)t

The final speed, v, is evidently exactly related to the force. So, if the force is constant, the end speed will also stay constant.

how does the kinetic energy gained by a charge relate to the potential across the plates of a capacitor?

Answers

The voltage supplied determines how strong the electrostatic force is inside a capacitor, and the length among the plates determines how weak it is.

The energy held in the capacitor stays unchanged as plates spacing increases, while capacitance falls. As a result, there is only a potential rise inside the differential here between plates.

By virtue of energy conservation, kinetic energy (KE) must be proportional to the change in potential energy (qV), either conversely. In terms of numbers, the voltage among the plates and the electron's energy in electron-volts are identical. For instance, a 5000-V voltage differential results in 5000-eV electrons. Energy in potential is position-dependent. To put it another way, it varies based here on weight and height of the object. The mass and initial velocity affect the kinetic energy of that object. When we consider a waterfall, we can see that the motionless liquid now at peak of something like the drop possesses potential energy.

The virial theory argued that kinetic energy is equivalent to half of potential energy's negative figure. The double of negative kinetic energy is called potential energy. The kinetic energy's opposite, amount of energy, is the same.

a uniform flat disk of radius r and mass 2m is pivoted at point p. a point mass of 1/2 m is attached to the edge of the disk.

Answers

The moment of inertia (Icm) of the uniform flat disk without the point mass = Icm = MR².

The moment of inertia with respect to point P on the disk without the point mass =  Ip = 3MR².

The total moment of inertia (of the disk with the point mass with respect to point P) = I total = 5MR².

We know from the case, that:

Mass = 2M

Radius = R

Mass at the edge = M₂ = 1/2M

Distance between the centre of mass to point P = p = R

Distance of the point mass to point P = d = 2R

We know that the moment of inertia for an uniform flat disk = 1/2mr².

(a) Then the moment of inertia for the uniform flat disk is:

= Icm = 1/2mr²

= Icm = 1/2(2M)(R²)

= Icm = MR²

(b) Next, we will find the moment of inertia of the disk with respect to point P. We know that point P is positioned at the arc of the disk. Hence,

= Ip = Icm + mp²

= Ip = MR² + (2M)R²

= Ip = 3MR²

(c) Then, the total moment of inertia of the disk with the point mass is:

= I total = Ip + I mass

Now,we know that centripetal force is required to move along a curve.Also,due to friction same amount of force acts on the car to move along the surface.

It means centripetal force=mv²/r where v is the velocity of the body and r is the radius of the body is equal to force applied by the friction which is equal to =μmg  

So,mv²/r=μmg  

=>v²/r =μg

=>μ= v²/rg

Answers

The plane's landing speed was 250 m/s.

The force required to slow the plane down is equal to the spring constant multiplied by the amount it stretched. Thus, we can use the equation:

An ice skater is spinning with her arms out and is not being acted upon by an external torque.
When she pulls her arms in close to her body what happens to her angular velocity?

Answers

She boosts her angular velocity when she pulls her arms in toward her body since doing so causes her rate of spin to increase dramatically, which lowers her moment of inertia. She pulls her arms in with effort, increasing rotational kinetic energy.

What does the conservation of angular momentum entail?

The angular momentum of the system of particles is conserved if there is no net external torque at a given position in a fixed inertial reference frame:

You can see that the whole angular momentum is conserved. Any one of the individual angular momenta can change as long as the aggregate remains unchanged. This equation represents the conservation of linear momentum when there is no outside force acting on the system.

As a result, since the conservation of angular momentum can be demonstrated by an ice skater doing a spin. Her net torque is virtually zero because there isn't much friction between her skates and the ice. Furthermore, the friction is applied rather close to the pivot.

The satellite space explorer flies 180600 miles in 21 hours. Find the rate of change.

Answers

The rate of change, or speed, of the satellite space explorer, is approximately 8600 miles per hour.

Given:

Distance = 180600 miles

Time = 21 hours

The rate of change represents the speed or velocity at which the satellite is traveling.

Rate of change (Speed) = Distance ÷ Time

Rate of change (Speed) = 180600 ÷ 21

Rate of change (Speed) = 8600 miles /hour

So, the rate of change, or speed, of the satellite space explorer is approximately 8600 miles per hour.
