  • The consequent acceleration, in, is caused by doubling the net force, F, acting on the same object.ms^-2 is going to 2a.
  • What is net force?
  • The vector sum of the forces exerted on a particle or body is known as the net force. As with all actual forces combined, its corresponding torque, or net force, forms the resultant force and affects the object's rotational motion. A torque-free resultant force may be defined by a system of forces.

The acceleration would be 1m/s²

<h3>What is  Force?</h3>

putting pressure to a door to push or pull it. Because force is a vector variable, it has both magnitude and direction. Force is defined as the "product of mass and acceleration of a body," in accordance with Newton's second law.

Acceleration - any process that alters velocity. There are only two ways to accelerate: changing your speed or changing your direction, or changing both. This is because velocity is both a speed and a direction.

if the force applied is f

the mass of the object is m

and acceleration is a = 2m/s²

so the relation will be,

f = ma

f = m×2

ATQ,

Now, when mass is 2m

a = f/m

a = 2m / 2m

a = 1 m/s²

The average kinetic energy of water molecules is greatest in
user100 [1]
<h2>Answer: in a gaseous state </h2>

The average kinetic energy of the water molecules is greater in its gaseous state (in the form of water steam).

This is because in the gaseous state the water molecules are well separated from each other and can move freely in all the available space they have; because there are no cohesion forces that bond them.

In contrast to the liquid and solid state, in which the molecules have less movement.

A copper wire has a square cross section 2.0 mm on a side. The wire is 5.0 m long and carries a current of 2.0 A. The density of
kondor19780726 [428]

Answer:

30.22 hours

Explanation:

Given data:

A= l² = (2 x 10^{-3})² = 4 x 10^{-6} m²

Length 'L' = 5m

current 'I' = 2 A

density of free electrons 'n'= 8.5 x 10^{28} /m³

Current Density 'J' = I/ A

J= 2/4 x 10^{-6}

J= 5 x 10^{5} A/m²

We can determine the  time required for an electron to travel the length of the wire by

T= L/ Vd

Where,

L is length and Vd is drift velocity.

Vd can be defined by J/ n|q|

where,

n is the charge-carrier number density

|q| is is the charge carried by each charge carrier =>1.6 x 10^{-19}C

T= L/ Vd

Therefore,

T= L . n|q| / J

T= (4 x 8.5 x 10^{28} x |1.6 x 10^{-19}|)/5 x 10^{5}

T= 108800 seconds =>1813.33 minutes

Converting minute into hours:

T= 30.22 hours

Thus, time that is required for an electron to travel the length of the wire is 30.22 hours

A 800-gram grinding wheel 27.0 cm in diameter is in the shape of a uniform solid disk. (We can ignore the small hole at the cent
SSSSS [86.1K]

Explanation:

d = Diameter of wheel = 27 cm

r = Radius = \frac{d}{2}=\frac{27}{2}=13.5\ cm

m = Mass of wheel = 800 g

\omega_i = Initial angular velocity = 245\times \frac{2\pi}{60}\ rad/s

Equation of rotational motion

\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\frac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\frac{0-245\times \frac{2\pi}{60}}{50}\\\Rightarrow \alpha=-0.51312\ rad/s^2

Moment of inertia is given by

M=\frac{1}{2}mr^2\\\Rightarrow M=\frac{1}{2}\times 0.8\times 0.135^2\\\Rightarrow M=0.00729\ kgm^2

Torque is given by

\tau=I\alpha\\\Rightarrow \tau=0.00729\times -0.51312\\\Rightarrow \tau=-0.0037406448\ Nm

The torque the friction exerts is -0.0037406448 Nm
