is my answer correct plz explain i don't understand it.

Answer:

I believe it is True... I hope it is correct :)

Explanation:

Answer : False

Explanation :

Answer:

a = kL/m

Explanation:

Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:

F = kL

Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:

F = ma

Comparing both the forces, we get:

kL = ma

a = kL/m

girl what- I can't answer this but I need points so I'ma just put this random lol sorry tho . ask the tutor

Answer:

Platinum

Explanation:

The specific heat of a substance gives the amount of energy it takes to raise the temperature.

Answer:

In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.

Explanation:

Answer:

90cm

Explanation:

2x5=10

10x9=90

Answer:

90 cm

Explanation:

To find volume, the formula is V=LWH

L is the length, W is the width and H is the height:

9 x 5 x 2 = 90

So V = 90 cm

Hope this helps you out! : )

Answer:

Explanation:

it's correct trust me

Answer:

Heat is released.

Explanation:

Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled.

Answer: Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Explanation: hope it helps :)

Answer:

With the given information, we can assume that the start and the end of the trip are the same place. (Suppose, a tour where the bus starts at the school, then it goes to a given location, and then it returns to the school)

Now, the definition of displacement is:

The difference between the final position and the initial position.

But if the start and the end of the trip are the same place, then the initial and final position must be the same. Then the difference between the final position and the initial position is zero.

This means that the displacement of the school bus from the start to the end of its trip must be zero.

i was wrong sorry

Explanation:

Answer:

it is relatively weak distance Force

ordered from strongest to weakest the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity

Answer:

W₁ = 2F₀d

Explanation:

When a force is applied on a body, due to which the body displaced by some distance, then the work is said to be done. Hence, the work is the dot product of the force nd displacement.

W = F.d

where,

W = Work Done

F = Force Applied

d = Displacement

For student 1:

W = W₁ = ?

F = F₁ = F₀ i

d = 2d i + d j

Therefore,

W₁ = (F₀i).(2di + dj)

W₁ = 2F₀d(i.i) + F₀d(i.j)

W₁ = 2F₀d(1) + F₀d(0)

W₁ = 2F₀d + 0

W₁ = 2F₀d

Answer:

the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.

B) beyond the frost line in the nebula.

Answer:

The frequency of the wave is 5 Hz

Explanation:

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).

The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.

In this case:

Replacing:

50 [tex]\frac{m}{s}[/tex] = f* 10 m

Solving:

[tex]f=\frac{50 \frac{m}{s} }{10 m}[/tex]

f=5 Hz

The frequency of the wave is 5 Hz

Answer:

Your answer is false

Explanation:

Answer:

Yes, Most living thing need oxegen, plants need light to grow(food).

plants and animals need water. temputre is important too, most living things need a  tempure range. therefor, all(most) living things need these 5 thing to live.

just rewrite this in your own word

Answer:

$7.95

Explanation:

$5.75 cost per bag ÷ 47 apples = unit cost of $0.1223. thus, each apple cost $ .1223.

.1223 × 65 apples= $7.95

note_rounding apples to .12*65=$7.8
