BRAINLIEST TO THE CORRECT QUESTION

The acceleration of an object depends on the mass of the object and the amount of the force applied to it. It states that the acceleration of an object increases with increased force and decreases with increased mass.

Answer:

  1) see the diagram below

  2) (b) the length of the wire being tested

Explanation:

1) An ammeter is connected in series with the circuit branch in which you want to measure current. "Conventional current" enters the positive terminal of the ammeter. (You can think of it as a voltmeter across a small resistor. The polarity of the voltage matches the polarity of the current.)

A voltmeter is connected in parallel with the circuit element of interest. Here, you want to measure the voltage across the wire, so the voltmeter is placed in parallel with the wire. The positive terminal of the voltmeter is connected to the end of the circuit element that has the higher (more positive) potential.

2) The wording of the problem tells you which variable is independent:

  "A varies with B" means the independent variable is B

Here, the independent variable is the length of the wire.

Answer:

2.304 × 10^-28 N

Explanation:

Compute the force on each of two electrons when they are seperated in vaccum by a distance corresponding to the approximate size of an ato. (0.100nm)

Solution

The formula to use is

F = K Qq / r^2

Substitute all the parameters

F = 9 × 10^9 × (1.6 × 10^-19)^2 / (0.1 × 10^-9)^2

F = 2.304 × 10^-28 / 1 × 10^-10

F = 2.304 × 10^-18 N

Therefore, the force between each of the electron is 2.304 × 10^-18 N

Answer:

11 blocks

Explanation:

distance is adding up the numbers while displacement is the difference in starting and ending points

Answer:

The greater the density of a medium, the slower the speed of sound. This observation is analogous to the fact that the frequency of a simple harmonic motion is inversely proportional to m, the mass of the oscillating object.

Air molecules have more energy at higher temperatures, which means they vibrate faster. This allows the sound waves to also travel faster because they are propelled by collisions between the molecules

Answer:

0.50 s

Explanation:

Answer:

, pfx = pix + Jx.

Explanation:

The momentum principle tells us that impulse transfers momentum to an object.

If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object

increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.

Just as we did with energy, we can represent this “momentum accounting” with a

momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball

colliding with a wall in Figure 11.4. Momentum bar charts are a tool for visualizing

an interaction

Answer: 8.6m/s

Explanation:From KE=1/2mv^2

In order to make v the subject of the formula we divide both sides by 1/2m. Thus V^2 will be left alone on the RHS. But we are looking for v and not v^2. Thus we find the square root of KE1/2m

Meaning V= sqrt[3000÷1/2 of 80]

=sqrt[3000÷40]

=sqrt(75)

=8.6m/s

Answer:

I think deposition of C is the oldest deposit

Answer:

False

Explanation:

Fusion doesn't produce more.

Answer:

Energy = 51840 J = 51.84 KJ

Explanation:

The electrical energy delivered to the toy can be found out by the following formula:

[tex]Energy = (Power)(time)\\Energy = (VI)(t)\\Enegry = VIt\\[/tex]

where,

V = Voltage = 3 V

R = Resistance = 2.5 Ω

I = Current = V/R (Ohm's Law) = 3 V/2.5 Ω = 1.2 A

t = time = (4 h)(3600 s/1 h) =  14400 s

Therefore,

[tex]Energy = (3\ V)(1.2\ A)(14400\ s)\\[/tex]

Energy = 51840 J = 51.84 KJ

Answer:

The length at the final temperature is 11.7 cm.

Explanation:

We need to use the thermal expansion equation:

[tex]\Delta L=\alpha L_{0}\Delta T[/tex]

Where:

So, we have:

[tex]L_{f}-L_{0}=\alpha L_{0}(T_{f}-T_{0})[/tex]

[tex]L_{f}=L_{0}+\alpha L_{0}(T_{f}-T_{0})[/tex]

[tex]L_{f}=0.115+(12.5*10^{-6})(0.115)(1221-22)[/tex]

[tex]L_{f}=0.117\: m[/tex]

Therefore, the length at the final temperature is 11.7 cm.

I hope it helps you!

Answer:

Q1: c

Q2: a

Explanation:

you can tell the factors by looking at the formulas for kinetic and potential energy

for question 1  look at the formula for kinetic energy

[tex]KE=\frac{1}{2} mv^{2}[/tex]

the variables needed in order to calculate an object's kinetic energy are mass and velocity.

hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy

same thing for the second question

[tex]PE = mgh[/tex]

as g (acceleration due to gravity) is considered constant (10 [tex]m/s^{2}[/tex] ) it will not be considered as a factor

and thus, the factors affecting potential energy are mass and height

m = 340 kg

F = ma

Therefore, a = 1900/340 = 5.59

Answer:

D. Exothermic because energy is a product

Explanation:

ENDOTHERMIC REACTION: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.

EXOTHERMIC REACTION: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.

Hence, the correct answer for this question will be:

D. Exothermic because energy is a product
