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.

suppose that you have 2 boxes. one has a bottom of 0.25 m x 0.20 m and a mass of 55.5 kg. the other box has a bottom of 0.20 m x 0.40 m and a mass of 65.5 kg. find the pressure each box exerts on the ground and indicate which is the most
Answer:
Approximately [tex]1.1 \times 10^{4}\; {\rm Pa}[/tex] and [tex]8.0 \times 10^{3}\; {\rm Pa}[/tex], respectively (assuming that [tex]g = 9.81\; {\rm N \cdot kg^{-1}}[/tex].)
The [tex]55.5\; {\rm kg}[/tex] box exerts more pressure than the [tex]65.5\; {\rm kg}[/tex] box.
Explanation:
Let [tex]m[/tex] denote the mass of the [tex]55.5\; {\rm kg}[/tex] box.
The weight of that box would be: [tex]W = m\, g[/tex].
The normal force [tex]N[/tex] that this box exerts on the ground would be the same as its weight: [tex]N = W = m\, g[/tex].
If the contact area between the box and the ground is [tex]A[/tex], the pressure [tex]P[/tex] that this box exerts on the ground would be [tex]N / A[/tex]. That is:
[tex]\displaystyle P = \frac{N}{A}= \frac{m\, g}{A}[/tex].
The contact area between the ground and this [tex]55.5\; {\rm kg}[/tex] box is [tex]A = 0.25\; {\rm m} \times 0.20\; {\rm m}[/tex]. Substitute in these values and evaluate to find the pressure:
[tex]\begin{aligned} P &= \frac{N}{A} \\ &= \frac{m\, g}{A} \\ &= \frac{55.5\; {\rm kg} \times 9.81\; {\rm N \cdot kg^{-1}}}{0.25\; {\rm m} \times 0.20\; {\rm m}} \\ & \approx 1.1 \times 10^{4}\; {\rm Pa}\end{aligned}[/tex].
Similarly, for the [tex]65.5\; {\rm kg}[/tex] box:
[tex]\begin{aligned} P &= \frac{N}{A} \\ &= \frac{m\, g}{A} \\ &= \frac{65.5\; {\rm kg} \times 9.81\; {\rm N \cdot kg^{-1}}}{0.20\; {\rm m} \times 0.40\; {\rm m}} \\ & \approx 8.0 \times 10^{3}\; {\rm Pa}\end{aligned}[/tex].
Thus, the [tex]55.5\; {\rm kg}[/tex] box exerts greater pressure on the ground than the [tex]65.5\; {\rm kg}[/tex] box.

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.
