How could you increase the sliding friction between the sled and track? How could you decrease it?
Answer:
You could put sheet metal lining the bottom or something similar to that
Explanation:
Explanation:
If the normal force is the weight of objects you are sliding across the floor, adding or subtracting weight will increase or decrease the sliding friction. But also, if you are pulling an object with a rope, pulling at an upward angle will reduce the normal force.How is the strength of an electromagnetic affected by the number of turns of wire in coil

what is frictional force?
how to Express frictional force?
Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
Coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force.

The displacement needed by the airplane to return to its starting point is 12.53 km.
DisplacementFrom the question, we are to determine the displacement
Using the diagram attached, D is displacement
Using the Pythagorean theorem,
D² = 11² + 6²
D² = 121 + 36
D² = 157
D = √157
D = 12.53 km
Hence, the displacement needed by the airplane to return to its starting point is 12.53 km.

which type of light wave has the highest energy? which has the least amount of energy
Answer:
Red has the lowest energy and violet the highest. Beyond red and violet are many other kinds of light our human eyes can't see, much like there are sounds our ears can't hear. On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light.

In the absence of air resistance and starting from rest ... Select one or more: a. an object would fall quadruple the distance if you double the time b. an object would fall half the distance if you double the time c. a 2 kg object falls twice as fast as a 1 kg object d. an object would fall twice the distance if you double the time e. a 2 kg object falls as fast as a 1 kg object
Answer:
only E is true
Explanation:
A) to find out if it would fall 4x as fast by 2x the time we can look at the formula for free fall:
for free fall the Y = [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex] where Y is the distance fallen, g is gravity and t is time
so since the rate at which an object falls is the same (gravity stays the same) it will not fall faster with any alteration
B) An object would fall half the distance if you double the time
here we may need to check with an example:
lets say we fall for 2 seconds in the first and 4 in the second:
Y= 1/2 (9.8) (2)^2 gives 19.6m fallen
Y= 1/2 (9.8) (4)^2 gives 78.4m fallen
from this we can see that doubling the time does not half the distance
C) all objects fall at the same rate no matter their mass so this statement is false
D) from the example above we see again that doubling time does not double the distance
E) this statement is true
Option e is correct. So that a 2 kg object falls as fast as a 1 kg object. Height attained depends upon the time factor.
What is height?The vertical distance between the object's top and bottom is defined as height. It is measured in centimeters, inches, meters, and other units.
The height attained during free fall ;
[tex]\rm H = ut + \frac{1}{2}gt^2 \\\\ u = 0 \\\\ H=\frac{1}{2}gt^2[/tex]
The height attained during free fall is independent of the mass. Due to that, a 2 kg object falls as fast as a 1 kg object.
Hence,option e is correct.

A particle with a charge of +7.4 C is separated from another charged particle with a charge of
-3.6 uC by a distance of 1.4 m. Find the direction and the magnitude of electrostatic force
between the particles.
Explanation:
9 × 10^-3 × 13.59 = 0.122 N
The given question is incorrect I think the question you asking is:
A particle with a charge of +7.4μC is separated from another charged particle with a charge of -3.6μC by a distance of 1.4 m. Find the direction and the magnitude of the electrostatic force between the particles.
The electrostatic force between the particles is 0.122N. The direction of the force is from the negatively charged particle to the positively charged particle.
What is electrostatic force?The electrostatic force is the force of attraction or repulsion between two charged particles due to their electric charges. It is a fundamental force in nature and is described by Coulomb's law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Here in the Question,
Given Data:
Charge of particle 1 (q1) = +7.4 μC = 7.4 × 10^-6 C
Charge of particle 2 (q2) = -3.6 μC = -3.6 × 10^-6 C
Distance between the two particles (r) = 1.4 m
Coulomb's constant (k) = 8.99 × 10^9 N·m^2/C^2
Using Coulomb's law:
Electrostatic force (F) = (k * |q1| * |q2|) / r^2
where |q1| and |q2| are the magnitudes of the charges.
Substituting the values, we get:
F = (8.99 × 10^9 N·m^2/C^2) * (7.4 × 10^-6 C) * (3.6 × 10^-6 C) / (1.4 m)^2
F = 0.12219≈0.122
Therefore, The electrostatic force between the particles is 0.122N. Since one of the charges is negative, the force will be attractive, pulling the particles toward each other.

1) wavelength is 2
6m is 3 wavelengths so 6 = 3.. to find for one wavelength divide both sides by 3
6 = 3
2(m) = 1(wavelength)
2) amplitude is half of what they've given
2/2 = 1m
3) f = 1/t
time period = 1.5s for 3 wavelengths
time period for one wavelength is 1.5/3 = 0/5
so f = 1/0.5 = 2 Hz
