What is a limitation of the Big Bang model?

a 4050 N sled is being pushed with a force of 575 N. If it encounters a frictional force of 385 N… determine the net force

creativ13 [48]

According to the solving the net force is:

= 3,860.

<h3>Why is net force important?</h3>

The net force is the total of all the forces operating on an object, according to its definition. Mass can be accelerated by net force. Whether a body is at rest or in motion, another force is at work on it. When a system has a lot of forces acting on it, the phrase "net force" is employed.

<h3>What's the net force equation?</h3>

When a body is moving and multiple forces, such as the normal force, frictional force, and gravitational force, are acting on it, the combined effect is known as net force. As a result, is the net force formula. FNet equals Fa, Fg, Ff, and FN.

<h3>According to the given data:</h3>

4050 N sled

force of 575 N.

encounters a frictional force of 385 N

So the net force will be:

(Net)F = F₁ + F₂ + F₃

So,

(Net)F = F₁ + F₂ - F₃(frictional force)

(Net)F = 4050 + 385 - 575

= 3,860

According to the solving the net force is:

= 3,860.

An ideal gas at 0∘C consists of 1.0×1023 atoms. 20 J of thermal energy are added to the gas. Part A What is the new temperature

fomenos

Answer: New temperature T2 = 9.66°C

Explanation:

Given;

Energy added ∆E = 20J

Initial temperature T1 = 0°C

Number of atom = 1.0×10^23

Using the energy equation.

∆E = (3/2)nR∆T

∆T = (2/3)∆E/nR

Where ;

R = universal gas constant = 8.314J/mol-K

n = number of moles = N/Nt

Nt = number of atoms in one mole of gas = 6.022×10^23

n = 1.0 ×10^23/6.022×10^23= 0.166

∆T = (2/3)×20/(0.166×8.314)

∆T = 9.66

T2 = T1+∆T = 0 + 9.66

T2 = 9.66°C

A block of mass 3 kg slides along a horizontal surface that has negligible friction except for one section, as shown above. The

ivanzaharov [21]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is $F_f = 3 * -4$

Explanation:

From the question we are told that

The mass of the block is $m = 3 \ kg$

The initial speed of the block before entering the rough section is $u = 5 \ m/s$

The time taken is t = 0.5 s

The speed with which the block leaves the rough section is $v = 3 \ m/s$

Generally from kinematic equation

$v = u + at$

=> $a = \frac{v - u }{t}$

=> $a = \frac{3 - 5 }{0.5}$

=> $a = - 4$

Generally the magnitude of the average frictional force is mathematically represented as

$F_f = m * a$

=> $F_f = 3 * -4$

=> $F_f = -12 \ N$

The negative sign show that the force is acting in the opposite direction to the direction of motion of the block

At time t = 0 s, a wheel has an angular displacement of zero radians and an angular velocity of +26 rad/s. The wheel has a const

Alex777 [14]

Answer:

t= 25.04 s

Explanation:

Given that

Initial angular speed ,ωi= 26 rad/s

Angular acceleration ,α=0.43 rad/s²

We know that kinetic energy of the wheel given as

$KE=\dfrac{1}{2}I\omega^2$

I=Mass monent of inertia

ω=Angular speed

If kinetic energy is two time then the final angular speed

$\omega_f=\sqrt{2}\ \omega_i$

We know that

$\omega_f = \omega_i + \alpha\ t$

$\sqrt{2}\ \omega_i= \omega_i +0.43\times t$

t= 25.04 s

After 25.04 s then kinetic energy will become two times of the initial kinetic energy.
