Answer: the phase of the Moon would be a waxing gibbous.
Explanation:
if you continue to exert this force (in m/s2) once the crate starts to slip, what will the magnitude of its acceleration (in m/s2) then be?
The magnitude of the acceleration when the crate starts to slip will depend on the coefficient of friction between the crate and the floor.
Generally, the acceleration will be equal to the coefficient of friction multiplied by the acceleration due to gravity, which is 9.8 m/s2. So, if the coefficient of friction is 0.5, the acceleration of the crate will be 4.9 m/s2.
The coefficient of friction between two surfaces is determined by the nature of the materials (for example, the roughness of the surface) and the amount of force that is being applied to the surfaces. Generally speaking, the coefficient of friction increases as the force increases.

a car starts from rest, after 10 s the speed of the car is 25 m/s. what is the magnitude of the car's acceleration?
the magnitude of the car's acceleration is 2.5 m/s^2.
The change in velocity (delta v) over time can be used to determine the amount of an automobile's acceleration (delta t). Acceleration is calculated as follows:
a = Δv / Δt
Given that the car begins at rest (with a beginning velocity of v0 = 0 m/s) and reaches a final speed of 25 m/s after 10 seconds, the acceleration can be calculated as follows:
v = beginning velocity - ultimate velocity.
Δv = 25 m/s - 0 m/s
Δv = 25 m/s
Δt = 10 s
A = 25 m/s/10 s for a = v/t.
a = 2.5 m/s^2
Consequently, the automobile accelerates by 2.5 m/s2.

Yes, we would classify Galileo as a nominalist because he claimed that qualities as that of color were mere names.
Galileo argued that color resided in the eye of the beholder and not really existed in the space. This concept is directly related to nominalism. Nominalism in metaphysics is the theory that universals and abstract things are only names or labels and do not genuinely exist. Nominalism has at least two main iterations. One interpretation rejects the existence of universals, which are things that may be expressed or illustrated by a large number of individual objects (e.g., strength, humanity). The alternative version expressly contests the reality of abstract objects, or those that do not exist in space or time.

weber constant for the volume of sound is 1/10. a car alarm is sounding off at 60 sound units. after five minutes it is programmed to get louder. how loud does it have to be for people to preceive it as louder?
The car alarm has to reach at least 75 sound units for people to perceive it as louder.
The Weber-Fechner law states that a noticeable increase in the intensity of a stimulus is proportional to the logarithm of the increase in the physical intensity. When it comes to sound, the law says that if a sound gets louder, people will only notice a difference if the change in volume is big enough.
To calculate the minimum increase in the volume required for a sound to be perceived as noticeably louder, we can use the formula for the Weber-Fechner law: V' = V * 10^(1/10) where,
V is the initial volume V' is the new, perceived volume.Let's say that a car alarm is sounding off at 60 units of volume. To find the minimum increase in the volume required for the car alarm to be perceived as noticeably louder, we can plug in the initial volume into the formula:
V' = 60 * 10^(1/10)
= 60 * 1.25992105

To calculate the number of electrons attached to or detached from the plastic sphere, we first need to calculate the charge on the sphere.
First, we can calculate the Stokes' drag force acting on the sphere:
F_drag = 6πηrvwhere
η = viscosity of argon (2.26 x 10^-5 Ns/m^2)r = radius of the sphere (assume it to be 1 mm)v = terminal velocity of the sphere (2.64 x 10^-5 m/s)Next, we can calculate the electrostatic force acting on the sphere:
F_electrostatic = qEwhere
q = charge on the sphereE = electric field (35 V / 1 mm = 35 x 10^6 V/m)Equating these two forces and solving for q, we get:
q = 6πηrv / EFinally, we can use the elementary charge (1.6 x 10^-19 C) to calculate the number of electrons attached or detached:
n = q / ewhere
e = elementary charge (1.6 x 10^-19 C)Substituting the values, we get:
n = (6π * 2.26 x 10^-5 * 10^-3 * 2.64 x 10^-5) / (1.6 x 10^-19 * 35 x 10^6)n = approximately 1.2 x 10^12 electronsSo, approximately 1.2 x 10^12 electrons have been either attached to or detached from the initially neutral plastic sphere, depending on the sign of the charge.

Electromagnetic interference (EMI) is also known as electric current and electromagnetic induction. It may also be referred to as magnetic induction due to the fact that the underlying concept is the same regardless of whether the procedure is carried out using an electromagnet or a static magnet.

5 m/s north is a velocity. Therefore, the correct option is option D among all the given options.
What is velocity?In physics, velocity is characterized as a vector measure of the motion's direction and speed. To be more precise, the change rate in an object's location relative to a reference frame and time is another way to describe velocity.
The definition of velocity simply states the rate of motion of an item in a certain direction. It determines how quickly or slowly something is going. Consider a scenario in which there are two moving items. If both items are going in the same direction, it is simple to determine which one is moving much faster than the other. 5 m/s north is a velocity.
Therefore, the correct option is option D.

Vehicle A and vehicle B collide and vehicle A loses 4000 kg•m/s of momentum. What is the change in momentum of vehicle B? What is the total change in momentum due to the collision?
The gain in momentum of vehicle B is 4000 kg•m/s
The total change in momentum due to the collision is zero.
What is the principle of momentum conservation?According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
As no external force applied, total momentum during collision remains conserved.
Hence, the gain in momentum of vehicle B = the loss in momentum of vehicle C
= 4000 kg•m/s
And, the total change in momentum due to the collision is zero.
