A solid sphere is placed on a frictionless floor in a very long corridor and is given a quick push so that it begins to slide, without rotating, along the corridor. How would the angular speed of the sphere be changing if the floor were not frictionless?

A.) It would remain zero because the net torque is still zero.
B.) It would remain zero because the angular momentum is conserved.
C.) It would be increasing until the slipping between the sphere and the floor stops.
D.) It would be increasing until the linear and the angular speeds become equal.
E.) It would be increasing until the translational motion stops.

Answer:

increases its amplitude.

Answer:

Ik its mass and velocity but not sure if its also shape

Its shape of an object that is not needed to find the kinetic energy of an object.

The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Answer:

the work done on the car is 7,500 J.

Explanation:

Given;

distance traveled by the car, d = 150 m

applied force, F = 50 N

The work done on the car is calculated as;

W = F x d

W = 50 N x 150 m

W = 7,500 J

Therefore, the work done on the car is 7,500 J.

Answer: 2.92 s

Explanation:

Given

Mass of ball is [tex]m=3.9\ kg[/tex]

The initial velocity of the ball is [tex]u=-3.5\ m/s[/tex]

Velocity after the rebound is [tex]v=15.9\ m/s[/tex]

Force during the contact is [tex]F=25.9\ N[/tex]

We know, change in momentum is Impulse

[tex]\Rightarrow F\cdot \Delta t=m(\Delta v)[/tex]

[tex]\Rightarrow 25.9\cdot \Delta t=3.9(15.9-(-3.5))\\\\\Rightarrow \Delta t=\dfrac{3.9\times 19.4}{25.9}=2.92\ s[/tex]

Thus, the force is applied for 2.92 s

Answer:

Metals is defined as the solid material which shows lustrous appearance and is a good conductor of electricity while non-metal are defined as the material which are not in solid form, have no luster and are bad conductor of electricity.

Two metals which are so unusual are mercury and sodium because metals are generally solid bur mercury is present in liquid form and metals are hard but sodium is so soft.

Two non-metals which are so unusual are diamond and iodine because diamond is opposite to the property of non-metals that is hard and iodine shows lustrous appearance whereas non-metals are non- lustrous.

Hence, Two example of metals are mercury and sodium and two example of non-metals are diamond and iodine.

Answer:

20N

Explanation:

mass=weight/gravitational pull

mass=120/10

mass=12Kg

weight=mass×gravitational pull

=12× (⅙of 10)

=12×1.666666666667

=20N

Answer:

0.84m

Explanation:

0.51+0.43=0.93

πr can be 22/7 or 3.14

radius is 2x2= 4

3.14 divide0.93divide 4

=0.84m/s

Answer:

0.605 m (approx.)

Explanation:

We know, given the radius and the circular velocity we can yield the centripetal acceleration using this equation,

[tex]a = \frac{v^2}{r}[/tex]

From this equation, we can solve for [tex]$r$[/tex] like this,

[tex]r = \frac{v^2}{a}\\r = \frac{0.51^2}{0.43} m \\ = 0.605 m[/tex]

Answer:

The gravitational potential energy (GPE) of the object is 294 J.

Explanation:

Given;

height of object, h = 3 m

mass of the object, m = 10 kg

acceleration due to gravity, g = 9.8 m/s²

The gravitational potential energy (GPE) of the object is calculated as follows;

GPE = mgh

substitute the given values and solve for GPE

GPE = 10 x 9.8 x 3

GPE = 294 J

Therefore, the gravitational potential energy (GPE) of the object is 294 J.
