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.
The angular speed of the sphere be changing if the floor were not frictionless, it would be increasing until the slipping between the sphere and the floor stops. Hence, option C is correct.
What is Friction?Friction refers to the resistance to a thing moving or rolling over another solid object. Although friction force can be beneficial, for instance the traction required to move without slipping, they also provide a significant degree of resistance to motion.
In order to overcome frictional forces in the working components, about 20% of an automobile's engine power is used.
The attractive forces, also known as stickiness, between the contact zones of the surfaces, that are always microscopically uneven, seem to be the main contributor to friction between alloys. These "welded" joints are shredded, and friction is created by the imperfections of the rough surface scuffing up against the softer surface.

A uniform, horizontal 300 N beam, 5.00 m long, is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0° with the horizontal. If a 600 N person stands 1.50 m from the wall, find the tension in the cable and the force exerted on the beam by the wall
Answer:Given A uniform horizontal beam with a length of 8.00 m and a weight of 200 n is attached to a wall by a pin connection ( allows rotation). Its far end is supported by a cable that makes an angle of 53 degrees with the horizontal. If a 600 n person stands on the beam at 2.00 m from the wall , find the tension in the cable
Now the force acting on the beam are the gravitational force of earth and weight attached to a wall is 200 N which acts at centre. Also force of person standing is 600 N and force exerted is r and tension is T , also torque due to r is zero because it acts at the pivot point. So r = 0
Torque due to tension in the rope is sin 53 x 8.00 x T.
Torque due to force is 2.0 m x 600 N
The weight of beam acts in the centre since the beam is uniform.
So we have
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Explanation:
The tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N respectively.
What is force?Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
L is the length 5.00 m long,
[tex]\rm \theta[/tex] is the angle of 53.0°
d is the distance = 1.50 m
T is the tension in the cable
F is the force exerted on the beam by the wall= ?
Torque due to tension in the rope is
[tex]\rm \tau = 8.00 \times sin 53^0 \times T[/tex]
Force due to the torque will be;
F= 2.0 m x 600 N
F= 1200 N
The net tension is found as on applying the static equilibirium equation;
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Hence the tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N .

If a wave has a speed of 200 m/s and a frequency of 25Hz, what is the wavelength of the wave?
Answer:
8m
Explanation:
v=f×lamda i.e wavelength
from the question v=200 m/s, f=25Hz, lamda=?
200=25×lamda
lamda=200/25(if you divide both sides by 25)
therefore, lamda=8Hz

determine the density in kg/m3 of a solid whose mass is 40 and whose dimension in centimetre are 30×4×3
Answer:
Density = 11.11 kg/m³
Explanation:
Given the following data;
Mass = 40 kg
Dimensions = 30×4×3 = 360 cm³ to m³ = 360/100 = 3.6 m³
Thus, volume = 3.6 m³
Now, we can find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
Density = 40/3.6
Density = 11.11 kg/m³

If two alpha particles (each with two protons and two neutrons) are 0.500 m apart, what is the electric potential energy of the system?
Answer:
U = 1.84 10⁻²⁷ J
Explanation:
Electric potential energy is
U = k q₁q₂/ r
in this case the electric charge is
q = 2 p
q = 2 1.6 10⁻¹⁹
q = 3.2 10⁻¹⁹ C
indicate the distance between the charges is 0.500 m
we calculate
U = 9 10⁹ 3.2 10⁻¹⁹ 3.2 10⁻¹⁹ /0.500
U = 1.84 10⁻²⁷ J

A lever of class 1 has a lotal length of 3m and is
able to lift a load of 60N with a force of 30N at a Time Find
the position of the fulcrum.
Answer:
Fin Lin = Fo Lo Work = Work out where in = input and o = output
Fin / Fo = Lo / Lin = 30 / 60 = 1/2 (input force = 1/2 output force)
Lin + Lo = 3
Lo = 3 - Lin
1/2 = (3 - Lin) / Lin from above
1/2 = 3 / Lin - 1
3 / Lin = 1.5 and Lin = 2
So the input length = 2 m and the output length = 1 m
A 1500 kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is a pipe with radius of 24 cm at the top and 2cm at the bottom. To generate an upward acceleration for the car of 1.0 m/s2, how much force must be applied to the small end of the pipe? The answer is NOT 102 N btw
Answer:
The force that must be exerted at the other end is 102.08 N/m₂
Explanation:
Using Pascal's formula; P₁ = P₂
P₁ = F₁/A₁ = m*g/(πr²)
m = 1500 kg; g = 9.8 m/s², r = 24 cm = 0.24 m
P₁ = (1500 * 9.8)/(22/7 * 0.24 * 0.24)
P₁ = 81235 N/m²
P₂ = F₂/A₂
A₂ = πr² where π = 22/7; r = 2.00 cm = 0.02m
A₂ = 22/7 * 0.02 * 0.02 = 0.00126 m²
P₂ = F₂ / 0.00126 m₂
substituting in the formula P₁ = P₂
81235 N/m² = F₂ / 0.00126 m²
F₂ = 81235 N/m² * 0.00126 m²
F₂ = 102.08 N/m₂
