It means the experiment can be reproduced again and again with close results to that of the first experiment. please give brainliest?

Answer:

It means the same result is occur after every experiment.

Explanation:

If an experiment will exhibit reproducibility, it means that the same result will occur after every experiment is performed.

Reproducibility is defined as the ability of an experimenter to give same results after every experiment under the same condition without any affect of external factors. The conditions for reproducibility is that the experimental conditions will not change with time.

An apparatus like the one Cavendish used to ﬁnd G has large lead balls that are 5.2 kg in mass and small ones that are 0.046 kg.

Ber [7]

Answer:

The magnitude of gravitational force between two masses is $4.91\times 10^{-9}\ N$ .

Explanation:

Given that,

Mass of first lead ball, $m_1=5.2\ kg$

Mass of the other lead ball, $m_2=0.046\ kg$

The center of a large ball is separated by 0.057 m from the center of a small ball, r = 0.057 m

We need to find the magnitude of the gravitational force between the masses. It is given by the formula of the gravitational force. It is given by :

$F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67259\times 10^{-11}\times \dfrac{5.2\times 0.046}{(0.057)^2}\\\\F=4.91\times 10^{-9}\ N$

So, the magnitude of gravitational force between two masses is $4.91\times 10^{-9}\ N$ . Hence, this is the required solution.

What are physics? How do you use physics on a daily basis?

Keith_Richards [23]

The physics is involved in many daily activities,

Forrxample,

1. At the time of wake up when the alarm clock rings, the sound from the alarm clock is studied by using physics, the angular motion of the pins on the clock.

2. The oscillation and time period of the minute, second and hour hand.

3. The tranformation of our energy from food to the energy for motion of our body.

4. The balance of our house equipments on the tab

What fundamental frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep

kari74 [83]

Answer:

708.3 Hz

Explanation:

For an open-air column, like the empty can, the fundamental frequency is given by

$f_1 = \frac{v}{2L}$

where

v = 340 m/s is the speed of sound

L is the length of the column

In this problem, the length of the bottle is

L = 24 cm = 0.24 m

Therefore, the fundamental frequency is

$f_1 = \frac{340 m/s}{2(0.24 m)}=708.3 Hz$

A reasonable estimate for the height of the walls in an ordinary american home is?

Olegator [25]

A reasonable estimate for the height of the walls in an ordinary American home is 2.5m.

<h3>What is wall estimation?</h3>

Building gauge is of two sorts one is known as Rough Cost Estimate. This gauge won't depict the specific expense of the structure, however it can provide you with the rough expense worth of the structure that will help adequately in overseeing cash for the structure. Harsh Cost Estimate is directed in various ways for various sort of structures. The rough complete wall length is found in running meters in this framework and this all out length accumulated by the rate per running meter of the wall gives an actually solid cost. Assessment hypothesis is a part of insights that arrangements with assessing the upsides of boundaries in light of estimated experimental information that has an irregular part. The boundaries depict a fundamental actual setting so that their worth influences the circulation of the deliberate information.
