An object starts at position 12 on a horizontal line with a reference point of 0. What is the position of the object if it moves 14 units to the left?

Answers

Answer 1

Answer:

Answer:

The position of the object is $-2$

Explanation:

I add a picture of the situation in order to explain the question.

We are going to state the ''zero'' on a horizontal line. Then, we are going to state as positive the sense from left to right.

Now, if the object moves 14 units to the left , we need to subtract to the original position 14 units (because it will be a negative move given that the object is moving to the left) ⇒

$12-14=-2$

It new position will be at $-2$ .

In general, the first step to solve this kind of exercises is to set a reference system. Then, it is very important to draw the situation.

Answer 2

Answer:

-2 is the right answer

Which factor does not affect the resistance of a material?A. thickness

B. weight

C. length

D. temperature

Answers

Answer: The correct answer is option B.

Explanation:

Resistance is the property of the material which resists the flow of current.

The expression for the resistance is as follows:

$R=(\rho l)/(A)$

Here, $\rho$ is the density of the wire, l is the length of the wire and A is the area of the cross section of the wire.

The resistance of the wire depends on the length of the wire, area of the cross section of the wire and the temperature.

The thicker wire has less resistance. The thinner wire has more resistance.

The longer wire has more resistance in comparison to the shorter wire in length. The resistance of the wire increases with increase in temperature.

The resistance does not depend on the weight of the wire.

Therefore, the correct option is weight.

the best answer is b

A 10 kg bowling ball would require what force to accelerate down an alleyway at a rate of 3 m/s2? F=
M=
A=

Answers

The force to accelerate down an alley way will be "30 N".

In the given question, the values are:

Mass,

m = 10 kg

Acceleration,

a = 3 m/s²

As we know the formula for finding the force will be:

→ $Force = Mass* Acceleration$

or,

→ $F = m* a$

By putting the given values in the formula, we get

→ $= 10* 3$

→ $= 30 \ N$

Thus the above answer is correct.

Hello!

A 10 kg bowling ball would require. What force to accelerate down an alleyway at a rate of 3 m/s² ?

We have the following data:

F (force) = ? (in N or kg.m/s²)

m (mass) = 10 kg

a (acceleration) = 3 m/s²

We apply the data to the Net force formula, we have:

$F =m*a$

$F = 10\:kg * 3\:(m)/(s^2)$

$F = 30\:kg*(m)/(s^2) \to \boxed{\boxed{F = 30\:N}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

The force is 30 Newton

Our solar system formed from a huge cloud of dust and gas called a _____.a. disk
b. protostar
c. solar nebula
d. planetesimal

Answers

The correct answer is C. Solar nebula

Explanation:

According to scientists, the Solar nebula was rotating disk or cloud of dust and gas (mainly hydrogen and helio) that is believed was the origin of our solar system. Indeed, it is estimated the formation of our solar system began 4.6 billion years ago as the solar nebula began contracting forming first the sun in the center and then other elements such as planets. This theory was first proposed in 1734 by Emanuel Swedenborg; however, from the first proposal, multiple models have emerged related to this theory and nowadays, the solar nebula theory is the one that scientist believe explain the formation of our solar system and other solar systems. Thus, our solar system formed from a huge cloud of dust and gas called a solar nebula.

c. solar nebula

Based on the nebular hypothesis, our solar system formed from hydrogen gas and interstellar dust. The gas and the dust contracted and formed the early stage of the sun.

A solution is measured to have a pH of 2.3. What is most likely also true about the solution?1.)It has a low hydroxide ion concentration.
2.)It has a low hydronium ion concentration.
3.)It is neutral.
4.)It has no H2O molecules.

Answers

According to the pH scale, a solution that has a pH of < 7 is considered an acid. Since it is established that the solution is an acid, there will be a low OH- concentration (hydroxide ion) in solution. In terms of hydronium ion, an acid has a higher amount of hydronium ion concentration.

Answers

qualitative data
electronic temp probe

-type of data did the scientist record was qualitative data.

-tool the scientist would use is electronic temp probe

The scientist recorded an illustration of qualitative data.
He is recording the water's quality as perceived by him since he noted explicitly that the water's surface had an iridescent sheen.
This makes the kind or condition qualitative data because it cannot be expressed numerically.

What is an electronic temperature probe ?

Electronic thermometers use thermoresistive devices, in which the electrical resistance alters in response to changes in temperature, to detect temperature changes.
The tip of a probe contains this device, which could be a thermocouple or a thermistor.
