When is heat positive or negative? I need it please help me

Answers

Answer 1

Answer:
I may be wrong, but I really don't think there's any such thing as
negative or positive heat. Heat is one of the forms of energy, so
it can never pop up out of nowhere, and it can never disappear.
Like all energy, heat just moves from place to place. If it flows
out of one thing, then it flows into something else. So I don't think
it's ever correct to say that the heat that's over there, or the heat
that's moving from here to there, is positive or negative.

Flatworms can be cut in half, creating two new individuals, by _____.binary fission
multiple fission
fragmentation
budding

Answers

Flatworms can be cut in halfcreating two individuals by binary fission. Binary fission is a type ofasexual reproduction in which the offspring has the same features andcharacteristics of the parent. During binary fission, the DNA replicates intotwo and goes at the end of each membrane. And then the cell membrane divides intotwo daughter cells. Then cytokinesis follow.

Answer:

If you think about you're cutting and Flatworm in half. Flatworms don't naturally divide/create new individuals by binary fission. So, the answer would be c) fragmentation; based on the fact that you are the one cutting the Flatworm, not the other way around.

A student moves a box across the floor by exerting 23.3 N of force and doing 47.2 J of work on the box. How far does the student move the box?

Answers

Given:
23.3 N of force and doing 47.2 J of work

Required:
distance

Solution:
W = Fd where W is work, F is the force applied and d is the displacement caused by the applied force.

47.2 J = 23.3N (d)
d = 2.03 meters

If a wave has a frequency of 8hz it has a period of

Answers

The required period of the wave is 0.125 seconds.

What is the frequency and time period?

In physics, frequency and period are two related concepts that are used to describe the properties of waves. Period, on the other hand, is a measure of the time it takes for one complete cycle of a wave.

Frequency is a measure of how many cycles of a wave occur in one second. It is measured in units of Hertz (Hz), which is defined as cycles per second.

Here,
The period (T) of a wave is the time it takes for one complete cycle of the wave. It is related to the frequency (f) of the wave by the formula:

T = 1/f

Where T is in seconds and f is in Hertz (Hz).

Given that the frequency of the wave is 8 Hz, we can calculate the period as follows,

T = 1/f

T = 1/8

T = 0.125 seconds

Therefore, the period of the wave is 0.125 seconds.
