objects 1 and 2 attract each other with a electrostatic force of 36.0 units​

This process (called electrolysis) is not have a change of state. This comes from the fact that the substance (in this case water) does not keep its identity during the change, this means that we don't end up with the same substance; rather we have two new ones, hydrogen and oxygen.

Answer:

102 m upwards.

Explanation:

Just from a qualitative analysis we can tell the mass it needs to go upwards. How much we determine with the fact that the increase will be - in absolute value - equal to the work gravity does on it to go down that same distance.

Fixed that work being 1 kJ, we get

\(\vec F \cdot \vec{ \Delta h} = |F| |\Delta h| cos 0 = ( 9.8 N )\Delta h \cdot 1 = 10^3 J\\\Delta h = \frac {10^3}{9,8} m \approx 102 m\)

I= 0.39 A

OPTION B is the correct answer.

Answer:

P = 4[Pa]

Explanation:

Pressure is defined as the relationship between Force over area. So we can use the following equation.

\(P=F/A\)

where:

P = pressure [Pa] (units of Pascals)

F = force = 100 [N]

A = area = 25 [m²]

Now replacing:

\(P=100/25\\P=4[Pa]\)

\(\\ \rm\longmapsto P=\dfrac{F}{A}\)

\(\\ \rm\longmapsto P=\dfrac{100}{25}\)

\(\\ \rm\longmapsto P=4Pa\)

earth energy budget is the relationship between how much energy the earth receive from the sun and energy the earth radiates out.

Energy is described as the quantitative property that is displaced to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.

It is important to know that the magnetic field of the Earth depends on its properties inside its nucleus, which means the magnetic field is variable.

In other words, the polarity of the Earth's magnetic field changes its polarity over time.

A 20.0 N block slides over a horizontal table. If it takes 5.0 N to move the block at a constant velocity, the coefficient of friction is D. 0.25.

Given,

Frictional force (F) is 5.0 N

Normal force (N) is 20.0 N

The coefficient of friction (µ), a numerical value, is obtained by dividing the resistive force of friction (F) by the normal or perpendicular force (N) pushing the objects together.

i.e., µ = F/N

Calculating the coefficient of friction :

The frictional force is equal to and opposing the applied force since the box is traveling at a constant speed.

µ = F / N

µ = 5.0 N / 20.0 N

µ = 1/4 N

µ = 0.25 N

Thus, the coefficient of friction is D. 0.25.

a) Electric field strength is 1 N/C ; b) Acceleration of the sphere is 6.67 m/s² ;  c) It takes the sphere approximately 0.299 seconds to travel 0.1 meters.

Quantitative expression of the intensity of electric field at particular location is known as  electric field strength.

a) as F = qE

F is force experienced by the charged sphere, q is charge on the sphere, and E is electric field strength.

2 N = (2 C)(E)

E = 1 N/C

Therefore, electric field strength is 1 N/C.

b)  As F = ma

F is force experienced by the charged sphere, m is mass of the sphere, and a is the acceleration.

2 N = (0.300 kg)(a)

a = 6.67 m/s²

Therefore, acceleration of the sphere is 6.67 m/s².

c) d = (1/2)at²

d : distance, a :acceleration, t : time.

0.1 m = (1/2)(6.67 m/s²)(t²)

t = 0.299 s

Therefore, it takes the sphere approximately 0.299 seconds to travel 0.1 meters.

The complete question is below:

A vehicle, starting from rest, accelerates on a circular track with a 335m diameter. What is the distance travelled by the vehicle when it makes one complete cycle?

The function is not continuous at x=1, so the answer is A.

At x=1, the two pieces of the function meet. The first piece ends with an open dot at (1,0), meaning that the function is not defined at $x=1$. The second piece starts with a closed dot at (1,-1), meaning that the function is defined at x=1 and takes the value -1 there.

Since the function is not defined at x=1, it cannot be continuous at that point. Therefore, the function is not continuous overall.

Explanation: i did the test

The magnitude of the applied force and the mass of the object, together determine how an object's motion will change in response to the applied force.

When describing the effect of an applied force on an object's motion, two important factors to consider are:

Magnitude of the Force: The magnitude or strength of the applied force determines the amount of acceleration or deceleration experienced by the object. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. A greater force will result in a greater acceleration, while a smaller force will result in a smaller acceleration. Additionally, the direction of the force relative to the object's initial motion will determine if it speeds up, slows down, or changes direction.

Mass of the Object: The mass of the object being acted upon is another crucial factor. As mentioned earlier, according to Newton's second law, the acceleration of an object is inversely proportional to its mass. This means that for a given force, an object with a larger mass will experience a smaller acceleration compared to an object with a smaller mass. In simpler terms, it requires more force to accelerate a heavier object compared to a lighter object.

These two factors, the magnitude of the applied force and the mass of the object, together determine how an object's motion will change in response to the applied force.

Answer:

Explanation:

7a) t = d/v = 100/45cos14.5 = 2.29533...= 2.30 s

7b) h = ½(9.81)(2.29533/2)² = 6.46056... = 6.45 m

  or

  h = (45sin14.5)² / (2(9.81)) = 6.47 m

which rounds to the same 6.5 m when limiting to the two significant digits of the initial velocity.

In circular motion, the total acceleration has two components: the centripetal acceleration (a_c) and the tangential acceleration (a_t). The centripetal acceleration is directed towards the center of the circle, while the tangential acceleration is directed along the tangent to the circle at the point of interest.

θ = tan^(-1)(a_c/a_t) or θ = tan^(-1)(a_t/a_c)
