What is your hypothesis (or hypotheses) for this experiment?(physically science lab report)​

Physics
1 answer:
stealth61 [152]3 years ago
5 0

Answer:The hypothesis (or hypotheses) for this experiment would be :

1) Experiment of motion( movement) can be performed in this lab.

2) Experiment of motion( movement) can be performed better in this lab.

3)  Only experiments of motion( movement) can be performed in this lab.

4) Experiment of motion( movement) can be performed more accurately in this lab.

5) No experiment of motion( movement) can be performed in this lab.

Explanation:

The hypothesis (or hypotheses) for this experiment would be :

Experiment regarding motion( movement) can be performed in this lab.

And Conclusion would be:

This lab is for motion.

We can only conclude that this lab is for motion when we find out that the motion experiments can be performed better or with higher accuracy or none other experiment can be carried out as easily as the motion experiment.

We only conclude when we test the hypothesis .

The hypothesis can be tested in a number of ways such as showing better results, or showing negative results of the said statement.

So there can be a few hypotheses as follows.

1) Experiment of motion( movement) can be performed in this lab.

2) Experiment of motion( movement) can be performed better in this lab.

3)  Only experiments of motion( movement) can be performed in this lab.

4) Experiment of motion( movement) can be performed more accurately in this lab.

5) No experiment of motion( movement) can be performed in this lab.

A cyclist acceleration from 0m/s to 8m/s in 3second. what is his acceleration?​
umka2103 [35]

Answer:

2.66 m/s² .

Explanation:

Initial velocity , u = 0 m/s

Final Velocity , v = 8 m/s

Time Taken , t = 3 s

So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²

Find the direction (clockwise or counterclockwise) of the current induced in loop AA if II is steadily decreasing. The current i
IrinaVladis [17]

Answer: counterclockwise

Explanation:

As the area of the loop decreases steadily, the flux through the loop also decreases. By Lenz’s law, any induced current will tend to oppose the decrease. Using Flemming right hand rule (Fleming's right-hand rule which shows the direction of induced current) we know that magnetic field inside the loop due to a counterclockwise current comes out of the plane. Therefore a counterclockwise current will create a stronger magnetic field inside

the loop, tending to increase the flux.

When a wire loop is moved in the direction of the current or a wire loop is being pulled through a uniform magnetic field there would be no induced current ( current loop is said to be zero)

Question 10 of 10Which statements are true?Check all that apply.O A. If heat is added to a substance, the temperature alwaysincr
inna [77]

The true statements are B and C.

This comes from the following facts:

Even when heat is added to a substance in a change of phase the temperature does not increases since this heat is latent heat.

If you are given force and distance you can determine power if you know
weeeeeb [17]
Yes, we can determine power if we know force and distance.
As power= Force x velocity
and velocity= distance/ time.

To calculate the heat needed to melt a block of ice at its melting point what do you need to know?
777dan777 [17]

Answer:

D.The mass and the latent heat of fusion.

Explanation:

When a block of ice is at its melting point, it doesn't need any additional heat in order to reach that temperature. Instead, it needs heat in order to break the bonds between the molecules and change state from solid to liquid. During the phase change, the temperature of the substance does not change, since all the heat provided is used to break the bonds between the molecules.

The heat needed for the phase change is

Q=m\lambda_f

where

m is the mass of the block

\lambda_f is the latent heat of fusion

Therefore, we see that the correct answer is

D.The mass and the latent heat of fusion.
